Breakfast in Koorda before we head east toward Mukinbudin, where we make our first orchid hunting stop at Wundowlin Nature Reserve. Orchids discovered at this location include: Lemon-scented sun orchid (Thelymitra antennifera), Dainty blue orchid (Cyanicula amplexans), Little laughing leek orchid (Prasophyllum gracile) and Chameleon spider orchid (Caladenia dimidia).
Passing through Mukinbudin we come across an amazing mural featuring black cockatoos and Blue beard orchids, painted by Tammi de Rooy @tammiderooyart, which by the way is the feature image of this post. Next, we head southeast towards Westonia.
On the way we make another orchid hunting stop at Boodallin Soak located in the Westonia Common. After a quick check of the well Bob n Jan head into Westonia for an explore whilst we explore the granite outcrop. Orchids found include: Yellow granite donkey orchid (Diuris hazeliae), Little laughing leek orchid, Western wispy spider orchid (Caladenia microchila), Midget greenhood (Pterostylis mutica), Dainty blue orchid, Slender rufous greenhood (Pterostylis macrosceles) and Pink candy orchid (Caladenia hirta subsp. rosea).
After arriving in Westonia we enjoy lunch with Bob and Jan at the Cafe/Supermarket. They then go to check out the museum whilst we explore the Woodlands & Wildflowers Heritage Trail for orchids. This walk trail is also contained in the Westonia Common. Orchids found include: Dainty blue orchid with an Albino form found, Little laughing leek orchid, Ant / Clown orchid (Caladenia roei), Granite sun orchid (Thelymitra petrophila), Spoon-lipped rufous greenhood (Pterostylis spathulata) and Spider orchids of the Filamentosa complex. Unable to identify with a high probability of correctness, so have posted 4 pics of the various forms found.
Nearly 3pm so we had better keep moving. We hit the Great Eastern Hwy and venture eastward as far as Bodallin1 where we make another exploration stop. Many more Filamentosa complex spider orchids are found. I’ll not attempt to name them, but I’ll use iNaturalist.com for assistance and make edits as needed. Other than C. microchila and C. dimidia already listed today other possible species are: Glistening spider orchid (Caladenia incensum), Banded Ironstone spider orchid (Caladenia saxicola), Common spider orchid (Caladenia varians).
Other orchids found include the Dainty blue orchid, Ant / Clown orchid, Little laughing leek orchid, Yellow granite donkey orchid, Hairy-stemmed snail orchid (Pterostylis setulosa), and Little frog greenhood (Pterostylis occulta).
It is nearly 4pm so we move onto our next overnight accommodation, where we again catch up with Jan and Bob. The Palace Hotel in Southern Cross was a comfortable hotel with great meals. We hit the sack content.
After enjoying our hotel breakfast, we leave Newdegate and head towards Dragon Rocks Nature Reserve. Numerous stops are made along the track and then we explore the camping area which includes the flat granite rocks.
First orchid found was the Sugar orchid (Ericksonella saccharata), then further along the track a possible Dwarf zebra orchid (Caladenia pachychila) is found. Open to correction on this one. Other common orchids found along the way include the: Purple enamel orchid (Elythranthera brunonis), Western tiny blue orchid (Cyanicula aperta), Western wheatbelt donkey orchid (Diuris brachyscapa) Dancing spider orchid (Caladenia discoidea).
Along the track in we also come across our first standard looking spider orchids. Again, like yesterday I feel they are all variations of the Chameleon spider orchid (Caladenia dimidia).
Further common orchids were found at the flat granite outcrop area, including the Cowslip orchid (Caladenia flava subsp. flava), Pink candy orchid (Caladenia hirta subsp. rosea) and the Ant orchid (Caladenia roei).
Also found along the way was the Little laughing leek orchid (Prasophyllum gracile) and 2 Pterostylis orchids from different complexes. One is a spent orchid from the Vittata complex and the other is a budding orchid from the Rufa complex. Naming these is not possible.
Now onwards to our next stop, which was an unplanned stop at the intersection of Kulin-Holt Rock Road, where we found a memorial of the Holland Track, so pulled in for a photo op. Also took the opportunity to quickly explore the verge side vegetation for any orchids. Actually, found some including the Jug orchid (Pterostylis recurva) and more Chameleon spider orchids.
Pterostylis recurvaCaladenia dimidia
Heading west along the Kulin-Holt Rock Road we come to our planned lunch stop, Buckley’s Breakaway, which is located in the Un-named Nature Reserve No. WA27485. After a bite to eat we venture along the trail into the breakaways, which are an amazingly site. (Refer feature image)
Of course, our eyes are looking for orchids as we stroll along. We are not disappointed as we first come across the Sugar orchid, followed by the Frog greenhood (Pterostylis sargentii) and an unknown Banded greenhood (Pterostylis sp.). I originally identified this as the Mallee banded greenhood (P. arbuscula) however it is listed as flowering in early winter so it may just be a short specimen of the Dark banded greenhood (P. sanguinea)which does flower into September and is also listed as occurring in this vicinity. Please provide comments to assist with the ID.
On the return journey 2 more orchids are found. The Brittle snail orchid (Pterostylis timothyi) and more Western wheatbelt donkey orchids.
Pterostylis timothyiDiuris brachtscapa
We move on towards Kukerin our planned overnight hotel stay. However, we first make a planned orchid hunt and bush walk at a spot called The Jam Patch, which is located at the old North Lake Grace tennis club.
Orchids found that had been found earlier today include the: Pink candy orchid, Western wheatbelt spider orchid, Little laughing leek orchid, Chameleon spider orchid.
New orchids for the day include the: Salt lake spider orchid (Caladenia exilis subsp. exilis)* Cream spider orchid (Caladenia horistes)* Yellow granite donkey orchid (Diuris hazeliae)* Drooping spider orchid (Caladenia radialis), Possible hybrid, parents unknown (Caladenia x)*
Orchids marked with * may not be separate species, possibly just C. dimidia, D. brachyscapa, or C. radialis so please correct me in the comments section if so.
Time to head back to Esperance. I decide to take the Brookton Hwy direction and make my first stop along the highway in the State Forest in the Flint locale. At this random stop I was extremely lucky to stumble across the Bird orchid (Pterostylis barbata). This sole specimen though had not yet fully flowered, so its labellum was not visible. Also, the brown markings around where the labellum appears between the body forming petals was not yet evident. However, I am still confident in my identification.
Moving along the highway to the next Flint location1 in the hope that more species will be found. Parking up off the road I had a quick look around but was driven back to the car by a rain shower. I did find a nice donkey orchid specimen, however now the difficult task of identifying it. I am leaning toward the Common donkey orchid (Diuris corymbosa) which flowers from August to October. They are listed as growing between Mogumber and Tenterden in sandy, sandy-clay and lateritic soils in forests, woodlands and shrublands. (Colours differ due to mobile / camera pics)
Another orchid found in this quick search was a Silky blue orchid (Cyanicula sericea)which is distributed between Jurien Bay and Esperance. They occur from August to early-October and is found growing in sandy, sandy-clay and lateritic soils in forests and woodlands. They occur in greater numbers in the season following a summer bushfire.
The rain stopped for a bit so had another quick look and came across a wonderful Jug orchid (Pterostylis recurva). These orchids are distributed between Geraldton and Israelite Bay growing in sandy-clay and clay soils in woodlands and shrublands.
Final orchid found at this location was the small Little Pink Fairy orchid (Caladenia reptans subsp. reptans) which is distributed between Northampton and Esperance. They are recorded as growing in a wide variety if habitats; from coastal heath to dry inland woodland in sandy to clay loam to gravelly soils.
Well, I didn’t get far along the highway before I made another stop, this time in Westdale1. Pulling off the road I make a beeline for the bush I hope to find the Blood spider orchid, as I have found it at this location on a previous visit. First up though I find some more donkey orchids flowering. Unsure of the ID as they may just be more Common donkey orchids D. corymbosa or may be another species. I will post to iNaturalist but they are rarely identified on that site either.
Then I stumble across a Green spider orchid (Caladenia falcata) which can also be referred to as the Fringed mantis orchid. These orchids are distributed between Wongan Hills and Jerramungup growing in a variety of woodland and shrubland habitats, on sandy to clay loam soils.
Then the targeted orchid is found, however in much lower numbers than before. As time is precious, I quickly take some pics of a couple, without exploring further. The Blood spider orchid (Caladenia filifera) is distributed between Wongan Hills and Tenterden growing in heathy to shrubby woodland and open forest, on clay loam, sometimes gravelly soils.
After successfully finding the Blood spider orchid it was time to move on. Further along the highway I pull into Jelcobine location9, in the Brookton Highway Nature Reserve. As per today’s previous locations the first orchid found was another donkey orchid. ID is proving difficult as 3 species are recorded in the Atlas of Living Australia for the surrounding area and the dorsal sepal is both erect and recurved in the flowers found. The options are Diuris brachyscapa, D. porrifoliaandD. corymbosa. Any help with identification would be appreciated.
Another yellow-coloured orchid is also found scattered over the location searched. The widespread and common Cowslip orchid (Caladenia flava subsp. flava) is distributed between Northampton and Israelite Bay. This orchid grows in a wide variety of habitats from wet forest and coastal heath to dry inland woodland, on deep sands to heavy clay loam soils.
Final orchid found at this spot was a solitary Sugar orchid (Ericksonella saccharata)which occurs between Paynes Find and Israelite Bay growing in a variety of habitats including heaths, woodlands, mallee scrubs and granite outcrops, on sandy to clay to gravelly loan soils.
Now as I am writing this blog some 7 mths after the actual date I have forgotten where my final search was completed as it was nearly 3pm, so more than 3 hrs since the previous stop. I did however stop for lunch in Corrigin so feel it was near Hyden. Upon researching Google Maps I have deduced it was at the Lake Hurlstone Nature Reserve stop.
2 species located here were previously found today so I will only post pictures of these. They were the Sugar orchid and Jug orchid.
Donkey orchids were also found and as usual the ID is difficult however based on the location and number of flowers it appears to be the Western wheatbelt donkey orchid (Diuris brachyscapa). These orchids are found growing between York, Tenterden and Ravensthorpe in woodlands and on and around the margins of granite outcrops.
Next, I stumble across a couple of small spider orchids. They appear to be the Chameleon spider orchid (Caladenia dimidia) which is found between Paynes Find and Norseman growing in seasonally moist areas on granite outcrops, mallee woodlands and slopes to seasonal creeks.
Underneath some bushes I spied some Hairy-stemmed snail orchids (Pterostylis setulosa) still in flower. These little guys are found between Kalbarri and Balladonia in WA as well as in NSW and SA. They grow in shrublands, woodlands and shallow soil pockets on granite outcrops.
The next stop was another 1hr later so from using maps again I believe I may have pulled into Pallarup Nature Reserve; however, this place is usually full of orchids so not really sure. However, pics were taken so will post them here. The Midget greenhood (Pterostylis mutica) is found growing in WA between Wongan Hills and the SA border. Also found in QLD, Vic, NSW, Tas and SA. Grows in shrublands, woodlands and shallow soil pockets in granite outcrops, as it appears many of our orchid do.
Another long drive back to Esperance, though this one was broken up with some fruitful orchid explorations. More than 12 species found, especially given the Donkey orchids found may be a few different species given the distance covered. This is the last day of Winter down here in Australia, so tomorrow will be Spring and the so-called peak flowering time for WA orchids.
So today I am heading out orchid hunting with another orchid enthusiast. We connected via the South East WA Orchid Group on Facebook. Luc has kindly offered to use his vehicle for the adventure. We have decided to head out east of Esperance and will be sharing our locations and techniques for finding orchids.
Our first location is Mount Ridley. He we pull up on the track, near a low granite outcrop, on the drive in from Dempster Road. This proves a fruitful location as we find multiple species within say 50sqm.
First picture taken is of the Cream spider orchid (Caladenia horistes). They are endemic to WA and are distributed between Southern Cross, Fitzgerald River N.P. and Balladonia. Grow in woodland and mallee scrubs, in damp locations on or around granite outcrops and along seasonal drainage lines.
(Caladenia horistes)
A nice triple headed donkey orchid is then captured in pixels. The Yellow granite donkey orchid (Diuris hazeliae) as the names suggests, grows in shallow soil pockets on granite. Also occurs in deeper sandy-clay soil along drainage lines. Distributed between Paynes Find and Balladonia.
(Diuris hazeliae)
Next up the Sugar orchid (Ericksonella saccharata) is found scattered across the site. These endemic white orchids are distributed between Paynes Find and Israelite Bay although absent on the West Coast and in the far South West. They grow in a variety of habitats including heaths, woodlands, mallee scrubs and granite outcrops, on sandy to clay to gravelly loam soils.
(Ericksonella saccharata)
Time for a blue orchid to be recorded. The Blue beard (Pheladenia deformis) is also known as the Blue fairy orchid. In WA they are found growing from Murchison River to Israelite Bay. They also occur in SA, Vic, Tas, and NSW. Varied habitats from the coast to inland plains and foothills.
(Pheladenia deformis)
And the last orchid found at this location is the Small mantis orchid (Caladenia attingens subsp. gracillima). Found between Jerramungup and Israelite Bay growing in sandy and sandy-clay soils in woodlands and shrublands.
(Caladenia attingens subsp. gracillima)
We move onto the main parking area and head into the bush adjacent to the granite outcrop. After quite some time of not finding anything in flower I stumble across a patch of small orchids. Very excited as I have only found these particular orchids once before. Back in 2018 at Wattle Rocks along the Holland Track.
The Dwarf zebra orchid (Caladenia pachychila) is found growing between Nerren Nerren Station and Mt Ragged. Typically, an inland species growing in mallee heaths and scrubs, on sandy to clay loam soils, also in shallow soils on granite outcrops, usually sheltered under shrubs
(Caladenia pachychila)
Intermixed with the dwarf zebra orchids were some small spider orchids. They appear to be more Cream spider orchids.
(Caladenia horistes)
Moving a little further west along the rock edge, still in the bush, I come across a larger spider orchid. I believe this to be the Rigid white spider orchid (Caladenia longicauda subsp. rigidulus). They are located between Ravensthorpe and Israelite Bay and inland to Balladonia growing in woodland and mallee scrubs, usually on or around granite outcrops. Also occurs on winter-wet flats and along watercourses.
(Caladenia longicauda susbp. rigidulus)
Where the track hits the granite in an isolated patch of vegetation I find another Yellow granite donkey orchid. Before we drive on, I quickly check out the Resurrection bush growing on the flat granite for any orchids. Here I found some more Cream spider orchids.
(Diuris hazeliae)
(Caladenia horistes)
Ok so now we jump back into the 4WD and take the track along the edge of the granite that leads up to the Aboriginal Rock Art.
Under the surrounding scrub a single Western tiny blue orchid (Cyanicula aperta)is found. Located between Dumbleyung and Mt Ragged growing in mallee scrubs and woodland, on sandy to clay loam soils, also on and around granite outcrops in shallow gravelly soils.
(Cyanicula aperta)
Another solitary orchid found was the Jug orchid (Pterostylis recurva). These occur between Geraldton and Israelite Bay growing in sandy, sandy-clay and lateritic soils in forests, woodlands and shrublands. In inland areas it is also known to occur on granite outcrops in shallow soil pockets.
(Pterostylis recurva)
The Little laughing leek orchid (Prasophyllum gracile)was found growing in the moss on a shallow soil pocket in the granite rock. These orchids occur between Shark Bay and Eyre also growing in sandy, sandy-clay and granitic soils in woodlands and shrublands. Near the coast they also occur in seasonally wet flats.
(Prasophyllum gracile)
In the scrub above the rock art Luc stumbles across a great bunch of Rigid white spider orchids, so I just have to share a pic of these.
(Caladenia longicauda subsp. rigidulus)
Also found nearby was a single Hairy-stemmed snail orchid (Pterostylis setulosa) still in flower. In WA these occur between Nerren Nerren Station and Balladonia. They also are found in SA and western NSW. They are a common orchid growing in shallow soil pockets on inland granite outcrops as well as sandy, sandy-clay and granitic soils in woodlands and shrublands.
(Pterostylis setulosa)
Also found was a Sugar orchid, more Cream spider orchids and Yellow granite donkey orchids.
Another first found for the day was a Lemon scented sun orchid (Thelymitra antennifera)growing in the middle of a resurrection plant. These are found between Shark and Israelite Bays, growing on creek margins, seasonally moist flats and granite outcrops.
(Thelymitra antennifera)
Time to move on so Luc takes us to a spot where he has found many Blue beards. It is along the track to the secondary parking area. There we found many Blue beards but many had finished the season already. We did have a quick look around for anything else. Alas nothing else found.
Blue Beards are found in various shades of blue/mauve and can even be found in white.
(Pheladenia deformis)(Pheladenia deformis)
Moving south down Dempster Road to one of my spots (Wittenoom hills3) in the Mt Ridley Nature Reserve which is a location new to Luc. It was here I found shell and greenhood orchids on a previous visit. It will be interesting to see what is found this time.
First up Luc finds the Midget greenhood (Pterostylis mutica). In WA these orchids are found between Wongan Hills and the SA border, whilst also being found in SA, Vic, NSW, Tas and southern QLD. They grow in sandy, sandy-clay and loamy soils in woodlands and scrublands.
(Pterostylis mutica)
Then a small spider is seen hiding in the dry gum leaves and sticks. I had not found this species at this location before, so that was exciting.
The Sigmoid spider orchid (Caladenia sigmoidea) is found between Mts Jackson and Ragged growing in mallee woodland on or around rocky outcrops, on heavy clay to lighter sandy loam and sometimes gravelly soils.
(Caladenia sigmoidea)
Found the shell orchid again but not in the numbers previously found.
The Dwarf shell orchid (Pterostylis brevichila) is found between Hyden and Mt Ragged growing in sandy-clay and clay soils in woodlands and shrublands.
(Pterostylis brevichila)
Close to the shell orchid more Sigmoid spider orchids were found. A very special one was discovered. It appears to be a hypochromic/lutea version. These lack certain colour pigments and usually appear yellowish white in colour.
Lutea (Caladenia sigmoidea)
Moving east along Norwood Road we pull into Mt Burdett which unlike Mt Ridley is found within the boundaries of the Nature Reserve bearing its name. We make our way around the base of the rock first, before climbing up to the Telstra tower. Orchids are found sparsely scattered around.
I will list those found at this location that had been found elsewhere today.
Jug Orchid Cream Spider Orchid Yellow Granite Donkey Orchid Western Tiny Blue Orchid
I have also included a video of the Cream spider orchids blowing in the wind, to provide you some idea of how hard it can be to get a good photo !!
Now for the more exciting finds here at Mt Burdett.
Firstly, comes the colourful Beautiful donkey orchid (Diuris pulchella)which occurs between Salmon Gums and Israelite Bay growing in shallow soil pockets on granite outcrops and deeper soils in surrounding shrublands.
(Diuris pulchella)
Next, we find the Pink bunny orchid (Eriochilus scaber subsp. scaber)still in flower. These small orchids are found between Jurien Bay and Cape Arid National Park usually after a previous summer bushfire. They prefer moist habitats, and our little patch is found growing in the moss on the granite rock.
(Eriochilus scaber subsp. scaber)
A single flowering Brittle snail orchid (Pterostylis timothyi)is the final orchid found at this location. They occur between Mt Lindesay and Mt Ragged and inland to Merredin, growing in sandy, sandy-clay, and clay soils in woodlands and shrublands
(Pterostylis timothyi)
Next stop is one of Lucs locations where he has found Curly locks before. This location is in Neridup2 along Coolinup Road.
Luc found the Southern Curly-locks (Thelymitra uliginosa) in flower which confirmed this was the correct spot. They are found between Busselton and Esperance (This location is over 50kms northeast of Esperance) growing in seasonally damp areas surrounding peaty swamps and granite outcrops.
(Thelymitra uliginosa)
Pics of orchids found here as before in previous locations: Jug Orchid Western Tiny Blue Orchid Cream Spider Orchid
I have also included a pic of the typical habitat we find the Southern curly-locks growing in.
(Pterostylis recurva)(Cyanicula aperta)(Caladenia horistes)Typical habitat for Southern Curly-locks
Another snail orchid is found, however due to its stature and bloated appearance I believe it to be another new species for the day: The Fawn snail orchid (Pterostylis parva). Found between Albany and Eyre and inland to near Lake King, growing in sandy, sandy-clay and clay soils in woodlands, shrublands and soil pockets on granite outcrops.
As the name suggests they are located between Bremer and Israelite Bays growing in clay and sandy-clay soils in seasonally moist woodlands and shrublands.
(Caladenia longicauda subsp. crassa)
A bright yellow orchid comes into view. The Common bee orchid (Diuris decrementum) is found between Wongan Hills and Israelite Bay growing in sandy-clay soils in open woodland and shrublands.
(Diuris decrementum)
Another donkey orchid found, however a different species thus time.
The South coast donkey orchid (Diuris brockmanii)is found between Ongerup and Esperance growing in sandy, sandy-clay and lateritic soils in mallee woodlands and shrublands.
(Diuris brockmanii)
Another smaller spider orchid is found, which is also whitish in colour.
This one appears to be the Common spider orchid (Caladenia varians)which is found between Kalbarri and Esperance growing in coastal heaths, woodlands, mallee scrubs, on granite outcrops and around salt lake margins, usually on well-drained sandy loam soils.
(Caladenia varians)
Final orchid for this location is the Dancing spider orchid (Caladenia discoidea).
This orchid is found between Kalbarri and Israelite Bay growing in a variety of woodland and heath habitats, usually on sandy soils.
(Caladenia discoidea)
We move onto what will be our last location of the day. This is another new location for me and is further up Coolinup Road so is now a Mt Ney1 location.
First up we are astounded as to the numbers of spider orchids found in a small open area under the trees.
The Cream spider orchid is found singularly and in clumps all over whilst the Rigid white spider orchid appears as isolated individuals.
Next up is an exciting find. A Blue china orchid is found with another one turning up within 30mins of searching. Not 100% sure of the ID so posted then separately on iNaturalist. Appears they may be 2 different species. First one is confirmed as the Boyatup china orchid (Cyanicula sp. “Boyatup”) which has yet to be formally named. As the name suggests they have a restricted range east of Esperance.
(Cyanicula sp “Boyatup”)
And the 2nd orchid is confirmed as being the Granite china orchid (Cyanicula nikulinskyae) which is found between Fitzgerald River and Cape Arid National Parks. As the name suggests they can be found growing in shallow soil pockets on granite outcrops, however, are also found growing amongst low shrubs or in open herbfields, on well drained gravelly loam soils.
(Cyanicula nikulinskyae)
Another orchid found in quite good numbers was the Short-sepaled spider orchid (Caladenia brevisura).
These occur between Jerramungup and Israelite Bay growing in woodland, mallee scrubs and on granite outcrops, in sandy to gravelly and clay loam soils.
(Caladenia brevisura)
Stumbled across an orchid that commences its season in August, so it is not fully open, however pic taken for recording purposes.
The Purple enamel orchid (Elythranthera brunonis)is found between Kalbarri and Israelite Bay, growing in heaths, woodland, open forest and malee scrubs in sandy, sandy-clay and lateritic soils.
(Elythranthera brunonis)
Orchids found previously today were also found at this location. Pics taken for recording purposes.
Common bee orchid South-coast donkey orchid Small mantis orchid Blue beard
Well what a day it has been. I took my first pic at 9.47am and my final pic at 4.07pm. Time to head back to Esperance 28 species recorded with a Lutea thrown in Plus 2 species of China orchids in 1 location An amazing day Thanks for the company, Luc
So today we decide to head north of Esperance to see what the season has produced. We don’t get far before we pull into our first stop of the day. Helms Arboretum is always a favourite stop.
Starting off small the first orchid found was the Zebra orchid (Caladenia cairnsiana).
These orchids are found growing between Lancelin and Esperance. They have only recently started flowering as their season commences in August and extends to early-November.
They are recorded as growing to heights of 400mm which would be amazing to find. Our specimens are more around the 200mm range.
Next our targeted orchid the Grass-leafed spider orchid (Caladenia graminifolia) was found.
These orchids also commence their flowering in August, then until September only.
They range from Mt Manypeaks to Israelite Bay so appears restricted to the south coast.
The Esperance king spider orchid (Caladenia decora)was represented by a single specimen found nearby the aforementioned orchids.
This king spider orchid is located from Bremer Bay to Cape Arid. Its season is mid-August to October.
We don’t stay longer at Helms as we only popped in here to find a flowering Grass-leafed spider orchid.
Our next stop is near Gibson14. We walk along the tracks and every so often we venture into the surrounding scrub.
This subspecies is the most widespread and ranges between Northampton and Israelite Bay. It also has the longest flowering season; July to early-December.
There are 4 subspecies of the Cowslip orchid. The other 3 are restricted to much smaller ranges that all overlap the range of the subspecies found around Esperance.
We did make an exciting find of a hammer orchid leaf in bud. From the leaf I believe it will be the King-In-His-Carriage orchid (Drakaea glyptodon).
These orchids flower August to October over a range between Eneabba and Esperance.
However, the most prolific orchid found at this location was the Esperance king spider orchid.
It was found either as a lonely specimen or in good size groups.
If any of the flowers pictured are the similar C. heberleana, please comment on this post.
We move further north up the highway to another location in the Gibson area 15. A gate had been installed which precluded us for heading down the track. We instead checked out the verge and walked a bit into the scrub.
This unusual but common orchid is found between Geraldton and Israelite Bay.
Flowering season is only from August to October
Deb has her eye in for spying orchids as she stumbles across an exciting find for this location.
The first orchid found is so small. Refer pic with the tip of my index finger for size comparison.
The Reaching spider orchid (Caladenia arrecta) is so named due to its erect petals.
Found between Bindoon and Israelite Bay.
Flowering season from late-July to mid-October.
We now move onto a new location, further north. We turn left at Hawkey Road them immediately right into Swan Lagoon Road. Our first stop 16 along this road is down a track in some bushland. We take this slowly and regularly get out to walk along and into the surrounding scrub. It is along this track that we pull over and have lunch from the back of the Triton.
The orchid that stands out for this location is the Western Tiny Blue orchid (Cyanicula aperta). It was found in huge numbers.
They are found flowering from August to early-October between Dumbleyung and Mt Ragged.
They have horizontally held petals and lateral sepals and can grow up to 150mm in height.
Another very similar orchid is also found, however not is such great numbers.
The Sugar orchid (Ericksonella saccharata) flowers in August and September between Paynes Find and Israelite Bay.
A small number of Midget greenhoods (Pterostylis mutica)were found along the way.
These orchids flower from July to October between Wongan Hills and the SA border.
They can grow to 200mm in height and can have up to 15 small green flowers.
A further Pterostylis orchid is found in small numbers.
The Brittle snail orchid (Pterostylis timothyi) flowers July to September between Lake Cronin and Esperance.
Some distinctive features are having a small rosette of pointed prominently veined leaves and only one or two stem leaves.
The we find one of the newest named Greenhoods. The Mallee banded greenhood (Pterostylis arbuscula) was formally named in 2018.
The flower between Dalwallinu and Eyre bird observatory during the months June and July.
As we are now in August this could explain why we only found two still in flower.
Amazingly we find a Grass-leafed spider orchid in this new location. So that makes a third spot we have found this orchid. Helms and Stokes NP are the other locations.
Another orchid of the Pterostylis genus is found. Only one specimen found, so was very lucky to have spotted it.
This time it is the Dwarf shell orchid (Pterostylis brevichila) which flowers from July to September.
It has an inland southeastern range, occurring from Hyden to Mt Ragged.
The Jug orchid is found at numerous spots in this location.
Pictures taken for registration purposes.
Just before we decide to have a break for lunch, we finally find a donkey orchid.
There are 2 possible ID’s for these orchids. They could be the South Coast donkey orchid (Diuris brockmanii)or the Yellow granite donkey orchid (Diuris hazeliae).
Flowering is June to early August and Aug to September respectively. So, the ones that already have finished flowers could very well be the former.
As both are recorded for the Grass Patch area any assistance in positive ID would be appreciated.
Note the brightness of the yellow is greatest with the mobile phone pics.
Whilst eating lunch we still explore nearby. It is here we find some different orchids than found previously today.
These orchids flower from August to early-October between Jerramungup and Israelite Bay.
The flowers are green, yellow and red in colour and can grow up to 350mm in height.
The prominently upcurved lateral sepals are distinctive to most mantis orchids.
Back on Swan Lagoon Road we travel further north and pull into another track which is much shorter, so we walk it. 17
Blown away by the numbers of Western tiny blue orchids found.
I have posted a video below to show how many occur in say 1 square metre.
So many Western tiny blue orchids
Another previously found orchid is also found in greater numbers.
The Midget greenhood rears it lime green coloured head again.
Also found was another Mallee banded greenhood.
Moving further north again we make a final stop in the Swan Lagoon Nature Reserve. Initially we turn up nothing in the lagoon area however further afield our luck changes.
Seems a regular occurrence today. Blue beards are also found in greater numbers than earlier today.
Well, we finally start finding the small spider orchids in flower. Actually, we find loads of them, and they may possibly be 2 species.
This orchid is a common southeastern inland species. It is found between Kondinin and Madura.
Flowers occur July through to early-October.
If another species is apparent from the pictures supplied, can you please enlighten me. I am swaying to C. dimidia or C. horistes
Intermixed with the wispy style spider orchids we also find the Short sepaled spider orchid (Caladenia brevisura)standing proud.
These orchids flower between Jerramungup and Israelite Bay during August and September.
The common name refers to the shortened sepal tips, when compared to the similar C. doutchiae.
Larger spider orchids appear as we progress with our exploration of this Nature Reserve.
Due to the shorter length of the petals and sepals, plus the dull white colouring I believe they are the Reclining spider orchid (Caladenia cruscula).
These orchids are found between Salmon Gums and Mt Ragged / Israelite Bay.
Flowering during August and September.
More donkey orchids are found near the large spider orchids.
Positive ID again not attempted. Could be D. hazeliae or D. brockmanii. Thoughts??
Midget and Mallee greenhood orchids were also found at this location. Pics for recording purposes.
Our final orchid of the day was the small Sigmoid spider orchid (Caladenia sigmoidea) which was very exciting.
The name “Sigmoid” refers to the ‘S’ shaped labellum tip.
These orchids grow between Mt Jackson and Mt Ragged.
Flowering during the months of July, August and September.
They are very small, ranging from 50 to 150mm in height. Their colouring blends into their surroundings. This makes finding them difficult.
We were blown away by the numbers found. Previously, we have only found them solo or as spread-out isolated specimens.
Well, this hunt was a great success. So many orchids found, with some in huge numbers. The highlights were the patches of Western tiny blue orchids and the large number of Sigmoid spider orchids found.
After a restful night at the Deralinya Homestead campground, we enjoy a peaceful breakfast. We then quickly pack up camp and head off on the track to Mount Coobaninya. But, after less than 2kms we turn back due to many trees fallen on the track. It seems the strong winds we encountered on the Nullarbor hit here with impact.
Back at the Homestead we pull up at the granite rock that forms the catchment for the dam and go for an orchid exploration. Sun orchids are found with some actually open so we can record their finding. They appear to be the Granite sun orchid (Thelymitra petrophila) which is found flowering from August to November. They occur from Mullewa out to Israelite Bay which is southeast of here.
So many Sun orchids found both flowering and still in bud. The other orchid found was the Little laughing leek orchid (Prasophyllum gracile) which are found between Shark Bay and the Great Australian Bight. These ones are not as far gone as the ones found yesterday.
We have a quick look at the homestead as the occupants had left for the morning. It was very interesting to see. The Heritage Council of WA has this recorded on it’s website : The well constructed buildings of local materials were built by a well known character of the area. George Burns Scott was a pioneer with a dam sinking plant who liked building and establishing stations and then moving on. The painter, A E Baesjou. lived there for some years as a little girl. The property was used as an outstation to Balladonia until 1936 when the roofs were removed. The last load of wool was taken out in 1920. Cattle were run there until 1936.
Moving further south we next stop at Breeboorinia Rock. The occupants from Deralinya Homestead cleared the track into here of fallen trees this same morning. This was opportune for us. Upon exploring the rock, we first come across the Granite sun orchid. Only 2 good specimens found with pics taken for recording purposes.
The Desert mignonette orchid (Microtis eremicola)was also found growing on the granite. As these orchids flower during September and October only a couple of newly flowering orchids were located. As the common name suggests, these orchids are found in a drier part of the state. Their recorded range is between Hyden and Balladonia.
Then in a bushy patch Deb comes across what appears to be very pale Cowslips. Upon closer inspection, I believe them to be the hybrid known as Dusky fairy orchid (Caladenia x erminea). This is due to the yellow/white colouring. It is also because of the hairs on the underside of the sepals. They are listed as occurring between Esperance and Perth during September through November.
One of the parents to the hybrid was also found in the thick scrub of the granite depression. The Cowslip orchid (Caladenia flava subsp. flava)was growing in an isolated group. They were very bright yellow in colour, in comparison to the hybrids.
We quickly check out the dam at the base of the rock. It is covered in wattle pollen, giving it a yellow tinge.

We make our way back to the Triton. On our way out we noticed the colour yellow in the surrounding grasses. Upon closer inspection, it is the Lemon-scented sun orchid (Thelymitra antennifera). This orchid is found flowering from Shark Bay to Israelite Bay during the months July through October.
We now head off and come to the beginning of the farms. In the middle of the farms is Clyde Hill Nature Reserve. Here we pull up and go for an exploration as this is our first visit to this reserve. Well, this proves to be a great location for orchids at this time of the season. Whilst walking along the track into the granite hill, we first come across a solitary Midget greenhood (Pterostylis mutica). A cobweb holds it prisoner.
Then another new orchid for the day is found. Pics of the various ones found in this location will be shown together to reduce the size of this post. The Short-sepaled spider orchid (Caladenia brevisura)flowers in August and September from Jerramungup to Israelite Bay.
Next up we find both the Lemon-scented sun orchid and Granite Sun orchid flowering. These 2 orchids are recorded as being the parents to an Un-named hybrid orchid ( Thelymitra antennifera x petrophila). Amazingly we find one of these in flower as well. I will post pics of all 3 orchids.
Another new orchid for the day is found. The Granite mantis orchid (Caladenia attingens subsp. effusa) flowers from August to early October between Peak Charles and Balladonia. The distinctive feature is the slightly upcurved lateral sepals. The related and possibly co-occurring Small mantis orchid has prominently upcurved lateral sepals.
Of course, we also come across the ever-faithful Cowslip orchid. These are found in most locations where orchids flower between Northampton and Israelite Bay. They can be found as early as July right through to December.
Next up is another new orchid for the day. The Pink fairies (Caladenia latifolia) are found from August to December between Kalbarri to Israelite Bay. The bright pink colour stood out from the surrounding greens and browns.
Well, we must keep moving so back to the Triton we go and southwards along Parmango road we head. Along the roadside we come to a spot that appears to have had a summer burn go through. We stop for an exploration. Glad we did as we did as we soon come across the Purple enamel orchid (Elythranthera brunonis). Actually, we end up finding loads in this spot which was amazing. These unique orchids flower from August to November, between Kalbarri and Israelite Bay.
As we had expected we came across Red Beaks (Pyrorchis nigricans) flowering. These orchids usually only flower after a summer fire the season before. But it is possible to find the odd one flowering without a fire.
Also discovered the large Esperance king spider orchid (Caladenia decora) which flowers from mid-August to October between Bremer Bay and Cape Arid.
Another similar coloured orchid is also found. The Dancing spider orchid (Caladenia discoidea) flowers August to early-October between Kalbarri and Israelite Bay.
An inconspicuous orchid is found in the early stages of development. The Common mignonette orchid (Microtis media subsp. media) is found flowering from September to January between Shark Bay and Eyre.
A surprising find was a solitary Common spider orchid (Caladenia varians) in flower. These orchids are found flowering from July to mid-October between Kalbarri and Esperance.
But the best find so far is the Custard orchid (Thelymitra villosa). This was not an expected find at all, so we were shocked in a good way. These orchids are found between Northampton and Esperance flowering over spring.
Two other orchids already found today were also found at this location. Cowslip orchid and Lemon-scented sun orchid just added to the yellow of the Custard orchid. Time to move on to the next location.
We arrive at Beaumont Nature Reserve, park up and head off exploring. Orchids that were recorded earlier today are also found at this location. They are captured in pictures below as a record of where they are found.
New orchids for the day were also found at this location. First up is the Zebra orchid (Caladenia cairnsiana) which flowers from August to early-November between Lancelin and Esperance.
Another yellow orchid is found. This time it is the Common bee orchid (Diuris decrementum). It flowers from August to early-October between Wongan Hills and Israelite Bay.
Another pink orchid is found. No not another fairy but a Pink candy orchid (Caladenia hirta subsp. rosea). These orchids flower from late-June to September between Kalbarri and Israelite Bay.
Also found some very pale Pink fairies so just had to share some pics of them. Do not believe they are a hybrid or lutea/hypochromic.
The we come across some donkey orchids. Two different species it seems. Firstly, the distinctive Beautiful donkey orchid (Diuris pulchella) is found. Then a South coast donkey orchid (Diuris brockmanii) is found. The difference in colouring is the major deciding feature.
Next, we come across some of the larger white spider orchids. Based on the location only, I will name one the Esperance white spider orchid (Caladenia longicauda subsp. crassa). As the name suggests they occur both west and east of Esperance. However, the other has a very different labellum with shorter fringe segments. I feel this one is the Reclining spider orchid (Caladenia cruscula). It occurs between Salmon Gums and Mt Ragged.
We are amazed to stumble across a large number of hybrids. The parents must be the Pink fairies and Cowslips which we have found at this location. The orchid is therefore the named hybrid Spectacular spider orchid (Caladenia x spectabilis). They do vary in colour quite a bit though. Although the hybrid between Cowslips and the Little pink fairy is very similar. One of the pics below seems quite different to the others. A firm ID may be harder to pin down.
As it’s around 4pm, we decide to move on to our final location. We wish to check if the Bird orchids have flowered yet in the Condingup area. We are excited to find them in flower. The Bearded bird orchid (Pterostylis turfosa) is a southern species found from Bunbury to Israelite Bay, flowering in spring.
Time to head home to Esperance. It has been an amazing last day of our 2023 road trip. So many orchids found, which makes up for the days in the desert. So, our adventure ends. Life is wonderful when spent doing what you love.
Well, it has finally arrived. The day we head off on our 2023 road trip. This year will be a little different as we will be travelling from Laverton in the eastern goldfields to Coober Pedy in South Australia. As we will be travelling the more remote desert areas, orchids will not play a part of this adventure other than in the first few and last few days of our adventure.
Heading north from Esperance we make at stop at Bromus Dam where we check out McPherson Rock. We are amazed to find 5 different orchid species in flower on and around the rock plus an extra species on the track back to the dam.

26/08/2023 ….. 2023 Road Trip Day 2
After a good night’s sleep in our Cot Tent, we enjoy breakfast before heading north. We arrive at the Victoria Rock Nature Reserve where we will have a bite to eat for lunch, then go exploring the rock for some orchids.

Now it is time to move north to catch up with Richard, Sandy and Noel, who will be our travel buddies for the next few weeks. We say goodbye to our beloved orchids until we return to WA in September.
Next stop on our winding drive back to Esperance is another new location. Anderson Lake Nature Reserve which is 30kms east as the crow flies from Pootenup Nature Reserve, will hopefully produce some different orchids. As we get close to the location it is apparent that it is much drier so let’s see if we actually find anything at all.
As anticipated, we struggled to find any orchids, however the ones found were indeed different. Very close to where we park, we find our first orchid. The Purple veined spider orchid (Caladenia doutchiae) flowers August through October, between Mullewa and Ravensthorpe. References checked indicate it is found growing on rises around salt lakes, which is exactly the habitat we are currently searching. Four sperate flowers were located, which portray the variable colouring to this species.
Smooth margined, variably coloured, red tipped labellum
Narrow band of labellum calli
Flowers 15 to 30mm across
Purple veins to sepals
Long, shortly clubbed lateral sepals
Short, backswept petals
It was another 15mins or so before we stumbled across another orchid. This time it was the Midget greenhood (Pterostylis mutica) that caught Debs eye. The lime green colouring stands out against the otherwise brown foliage. These small orchids flower July through October, between Wongan Hills and the SA border. They are also found in QLD, NSW, Vic, Tas and SA. Florabase mentions they are known to grow around saline lakes, again confirming we are in suitable habitat.
From the latin MUTICUS (without a point, awn less, blunt) alluding to the blunt petals and sepals.
The next orchid found was a pleasant surprise. First up we thought it was a frog greenhood, but as we settled in to take some photos it became apparent that it was another species. After getting back into the Triton we are excited to note that this is a new species for us. The Ruddy hood (Pterostylis perculta) flowers from late September to early November between Kojonup and Cape Arid National Park. It was only formally named in 2015, previously called sp. “Ongerup’ which alludes to its location. It is a small orchid growing to 150mm in height, may have up to 5 flowers per orchid and is found growing in sandy-clay and clay soils.
Almost hairless labellum
Straight to slightly upcurved lateral sepals
70-150mm in height
As alluded to earlier we had returned to the Triton as this location did not prove overly productive, however finding a new species is always amazing. We head north up to Gnowangerup, then west stopping along the roadside in Kebaringup. I believe this is only our 2nd time visiting this location so we will see what turns up this time.
Straight up the large white spider orchids catch our eye. The Stark white spider orchid (Caladenia longicauda subsp. eminens) is probably the species found, based solely on location. They flower August to early October between Moora and Esperance and can grow to 600mm in height.

Cowslip orchid (Caladenia flava subsp. flava)

More Purple veined spider orchids are found in better numbers. Then another single specimen on anorchid is found. The Common mignonette orchid (Microtis media subsp. media) is a widespread orchid being found flowering between Shark Bay and Eyre during the months of September through January. The final orchid found for the day was a good bunch of Jospeh’s spider orchid (Caladenia polychroma), which are found between Boyup Brook and the Fitzgerald River National Park during the months of September and October.

We decide to move on and look for somewhere to stay the night. As we have 2 vehicles and a camper trailer, we make the decision to check into the Ongerup Gardens Caravan Park for the night. It was a choose you own site sort of place, so we parked up close to the ablutions. This was a great day orchid hunting in our wonderful Western Australian outdoors.
A leisurely morning today as it is our last one for our 2022 road trip. We enjoyed breakfast whilst listening the raucous Galah flock as they ate on the ground then flew up when spooked into the nearby trees. Our first orchid location was not far away so we were in no rush.
Dempster Rock is our first hunt for the day. As per many locations, the first orchid found is the Hairy-stemmed snail orchid (Pterostylis setuloso), which is a common inland orchid. Only a couple found here and no more were encountered at this location, which is interesting.
We find loads of spider orchids which will as usual prove problematic to identify so firstly I will post the pics of other orchids found first. So the first non-spider orchid found was the common inland occurring Sugar orchid (Ericksonella saccharata)which is found in huge numbers later in the search. I will post some individual pics plus a video showing the large expanse of flowers.
Next up we find some Blue beards (Pheladenia deformis) growing sparsely around the location with one small clump in the early stages of flowering found. It is always nice to find a blue orchid as they are a rare colour for our Southwest orchids.
Another vibrant colour found is pink. The lone Pink candy orchid (Caladenia hirta subsp. rosea)stood out in the green grasses. No others found though, so we thank our lucky stars we came across this specimen.
OK, so now it’s time to record the spider orchid finds. I will start with the easier ones first. The Drooping spider orchid (Caladenia radialis) is a unique spider orchid with usually drooping petals and all sepals, plus has a smooth or slightly fringed labellum.
That’s it for easy ID, now it becomes more difficult. These striking red spider orchids are not recorded as occurring this far southeast. The two that have the closest listed range are the Slender spider orchid and the Red thread spider orchid. Both occur in pure red forms, and both are listed as having pendulous or near pendulous petals and lateral sepals. EDIT: With assistance from members of the FB group Western Australian Native Orchids I am now confident in naming this small clump as being the Slender spider orchid (Caladenia pulchra)
So now the identification gets even more difficult. First up I think these orchids are the Chameleon spider orchid (Caladenia dimidia) due to the backswept petals and whitish colouring to the flowers, however they are variable in colour, so maybe not a great defining feature. 🙂
Now many spider orchids with a creamy to yellow colouring confuse me even more. Some have dark filaments to the ends of the petals and sepals, whilst there are also differences in the colours of the labellum calli. They could be more of the species already identified today or possibly another species. Again, any help in ID would be appreciated.

Getting late so we had better move on. We did not get far before pulling into Sugg Rock Road to visit Kathleen Nature Reserve. We just park up on the road verge and head into the reserve to hopefully find some orchids. We do find some but not in great numbers. The first orchid found was another spider orchid, which I believe is another Joseph’s spider orchid. This was followed up by two headed one tangled together. Then yellowish coloured ones are found.
Then we find an orchid that was once included in the Caladenia genus but in Western Australia it has been added to its own monotypic genus, Ericksonella. The Sugar orchid is a distinctive white orchid with horizontally held lateral sepals.
The next three orchids found belong to the genus Pterostylis. First up the ever-reliable Jug orchid (Pterostylis recurva) is found. Then we find a good patch of Midget greenhoods (Pterostylis mutica) growing in numerous spots. Finally, the equally small Little frog greenhood (Pterostylis occulta) which was only named as a distinct species in 2021.
We are getting a pit peckish and plan on a counter lunch at Lake King Tavern, so we push on. However, on reaching the main road we notice a sign pointing west indicating Sugg Rock dam, so we cross the road to check it out. We did not find the dam but decided to check out the bush as it was a bit more open than in the Nature Reserve. We find some familiar orchids so take a photo to record the location and keep searching.
More spider orchids are found which appear to be more Joseph’s spider orchids.
Final couple of orchids found were more Pterostylis ones. A lone greenhood that was fertilised a while ago and a lone good quality shell orchid. The shell orchid is possibly a Green-veined shell orchid (Pterostylis scabra) which flowers May through August over a range from Kalbarri to Esperance.
Now finally it’s time to go and grab some lunch. We enjoy a cold bevvy and hot counter meal at the Lake King Tavern, before heading south to our last planned stop of the 2022 road trip, Pallarup Nature Reserve. Our particular spot is Pallarup Rock picnic area, where we park up and head off on foot to find some orchids. First up the colourful Pink candy orchids are found. Quickly followed up by the Sugar orchids and Blue beards.
Then we moved along the track toward the rock, where we came across some spider orchids. First up were the small Joseph’s spider orchids, however we also found the larger Pallarup white spider orchid (Caladenia longicauda subsp. ‘Pallarup’)which grows over a restricted range between Lake King and Ravensthorpe, growing in sandy soil on the margins of granite outcrops.

We venture onto the rock but not much catches our eyes, so we loop back into the surrounding bush and we find more orchids, this time from the Diuris genus. The South-coast donkey orchid (Diuris brockmanii) is found between Ongerup and Esperance during the months of June to August. I feel confident on this ID based on the location and the bright yellow colouring of the flowers, as the other possibility is a pale yellow in colour (D. brachyscapa).
More various orchids found including more Sugar, Bluebeard and Pink Candy orchids, plus a nice Jug Orchid and a very special Lutea or hypochromic candy orchid. As usual Pallarup Rock area always has something flowering during the season. It was a fitting place to end our 2022 Road Trip.
I trust you have enjoyed travelling with us on our 2022 Road Trip which had some exciting, scary, amazing and awe-inspiring times. There was a patch of no orchid hunting but there are areas of this great state of Western Australia that still need to be seen. 2023 will be similar as we venture across the desert to Coober Pedy in South Australia. Well, that is the plan for now.
