Heading up to Perth for a few days so made sure to stop along the way to look for some orchids in flower. First stop after 2 or so hours of driving is at the rock in Pallarup Nature Reserve. Only had a quick 15 min walk around and found 3 species.
Pink Candy orchid (Caladenia hirta subsp. rosea)
(Caladenia hirta subsp. rosea)
Sugar orchid (Ericksonella saccharata)
(Ericksonella saccharata)
Frog greenhood (Pterostylis sargentii)
There are 2 species of Frog greenhoods, but I did not obtain a closeup pic of the labellum, which is a distinguishing feature, so have listed the original name for now.
(Pterostylis sargentii)
Next stop was at the Lake Grace Lookout for a lunch break and of course an orchid hunt.
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
Keeping closer to home today I decide to go and check out the Kepwari Walk Trail. This trail is located in the Woody Lakes Nature Reserve. I park up at the spot between Woody and Windabout Lakes to commence the trail.
Not far along the track I spy some king spider orchids. They appear to be the Esperance king spider orchid (Caladenia decora). The Esperance king spider orchid comes in many shape and colour variations. Some will have clubbed petals, some will be mostly red, whilst others have minimal clubbing and may be almost completely creamy-green in colour. These variations can make a positive ID difficult especially given the related Heberle’s spider orchid (C. heberleana) is found in Esperance and looks very similar. Let alone it hybridises with the Esperance white spider orchid (C. longicauda subsp. crassa). C. longicauda and a possible hybrid were also found today. Other specimens are found further along the track especially the area between Woody and Wheatfield Lakes.
Up on the high ground section which provides a great view over Woody Lake I find some classy Pink fairies (Caladenia latifolia). Others are found further along as well, with a very pale pink, nearly white one being the highlight. Also found leaves and spent Mosquito orchids at base of a series of steps and in other patches.
Once down on the flats again and along the track between Woody and Wheatfield lakes the Cowslip orchid (Caladenia flava subsp. flava) appears. The yellow colouring differs between my camera and mobile phone pictures. The duller yellow I feel is closer to real life.
I did not complete the full trail before turning around as it is now lunch time and I’m starving. Orchid photos were taken on the way back to the carpark as well and are included in the pics already listed for each species. Just before making it back to the carpark I find a small orchid in bud. Pic was taken and I did plan to go back to check what it was when in flower. However, that was forgotten until way too late. Maybe next season.
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.
On the hunt for that elusive Winter Spider Orchid. To improve our chances, we are heading over to Lake King. To provide as much time as possible we have booked into the Lake King Tavern Motel for Saturday night.
However, as is usual for us we never go anywhere directly. Orchid hunting stops will be made along the way, plus we like to venture paths not previously travelled.
First up we check out a location in Coomalbidgup3 where we come across some bunny orchids.
Pictures of two findings only taken with the leaf not visible in one. The second pics show very small smooth margined leaves.
Unable to give a positive ID based on these pics so will leave as ??? bunny orchid (Eriochilus sp.)
The next couple of locations, one in Coomalbidgup4 and one in Munglinup,5 did not turn up any orchids.
I did come across a large Beehive located under a rocky overhang. I gave it a wide berth.
Another 2 stops made on the roadside verge of Lake Ace Nature Reserve followed by Kathleen Nature Reserve.
No luck in finding any orchids in flower.
We then visit a previously visited site nearby6 and here we only find some spent Pygmy orchids (Corunastylis fuscoviridis).
Oh well that was not a very successful day, orchid wise, however getting out in the bush is always enjoyable.
After spending a wonderful night at Lake King, we enjoy a leisurely morning. The after the 10am check-out we finally head out for further exploration.
Damnosa and Pallarup Nature Reserves are both checked. Unfortunately, nothing other than further spent Pygmy orchids are found.
Oh well time to go home and back to work on Monday.
The Winter spider orchids will have to wait for another year.
It’s past midway of May so we anticipate some other orchids are starting to show themselves. So, northeast of Esperance we head with our first stop being one of our usual haunts in Neridup1.
The only orchid found during a quick sweep of the location was the Hare orchid (Leporella fimbriata).
They are a very distinctive orchid with thin upright petals that appear to be ears and a prominently fringed labellum.
Flowering: March – June Distribution: Shark Bay to Israelite Bay
Moving on towards our planned destination we pull into a track on a whim and have a quick look around.2 Not much found here either.
First up we find the Pygmy orchid (Corunastylis fuscoviridis), however they are finished for the season. Pics taken for recording purposes only.
Flowering: March – May Distribution: Corrigin to Eucla
Then we come across the Banded greenhood (Pterostylis vittata) which is the most common of the greenhood orchids.
Flowering: April – September Distribution: Perth to Israelite Bay
Then a small greenhood orchid is found that is just sprouting its first flower. From the colouring and size, I believe it will be the Mallee banded greenhood (Pterostylis arbuscula).
Flowering: June – July Distribution: Dalwallinu to Eyre Bird Observatory
Next, we move onto our planned destination, Mount Burdett, which is also located in the Mt Burdett Nature Reserve. We enjoy a late bite to eat for lunch before starting our search.
On the granite rock we locate some bunny orchids growing. By referring to the latest book by Andrew Brown I ID them as the Eastern granite bunny orchid (Eriochilus dilatatus subsp. “eastern granites”).
Flowering: April and May Distribution: Esperance to Balladonia
Then around the back of the rock I discover the sole Hare orchid growing. Last year there were more but not today 🙁
Well not such a productive day, however it is always wonderful to get out on a beautiful sunny winters day.
Home alone for the weekend, so of course I head out looking for some early season orchids. Heading north out of Esperance I first pull into one of our regular haunts. To my dismay, it appears the track we used to check along is in fact a fire break. It had been re-cleared, though unfortunately a little wider this time. Thus, it cleared away the vegetation where we had previously found orchids. I decided to expand my search in the location. I included the other side of a Salt Lake. I was excited to find some orchids over the entire search area.
The first orchid found was of the Eriochilus genus. Due to the wavy edged leaf, I believe they are the Blunt-leaved bunny orchid (Eriochilusdilatatus subsp. brevifolius).
These orchids are listed as being found between the Murchison River and Toolinna Cove.
Flowering during the months of April, May and June.
Two specimens of the Leafless orchid (Praecoxanthus aphyllus) were found in the newly explored area past the Salt Lake.
The orchids are listed as occurring between Perth and Condingup.
Flowering during the months of March, April and May.
The common name is actually incorrect. The flowering orchids do have a leaf. However, it is minuscule (Minute bract only) when compared to the non-flowering leaf. Plus, it occurs at the very base of the flowering stem.
A farmer on a quad bike with his two dogs approached me. It appears I have been looking for orchids on his property. After discovering I was not a lost tourist, he was quite happy for me to stay.
I however decide to head back, taking one last hunt for any orchids in the old location.
Woohoo, I find one lone Hare orchid (Leporella fimbriata)growing in the shrubs alongside the newly cleared fire break.
These orchids are listed as being found between Shark Bay and Israelite Bay.
Flowering during the months of March, April, May and June.
I decide to head further north to the Red Lake Townsite Nature Reserve. This is a known location for the 4th early season orchid I am chasing today.
As luck would have it after walking along the track for quite a while, I finally find the Pygmy orchid (Corunastylis fuscoviridis).
The orchids are listed as occurring between Corrigin and Eucla.
Flowering during the months of March, April and May.
I finish the day a happy Chappy as I managed to find 4 of the early season orchids flowering. Each species was from a different genus: Eriochilus, Praecoxanthus, Leporella, Corunastylis.
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.
Breeboorinia Rock DamWattle Pollen covers the water
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.
