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.
So we move onto our 7th location of the day which is just another random roadside stop on the boundary between Coomalbidgup and East Munglinup localities. All depends on which side of the road you are 🙂
The Western tiny blue orchid (Cyanicula aperta) is the first orchid found at this spot. These little orchids are found between Dumbleyung and Mt Ragged from August to early-October.
Next up the Purple enamel orchid (Elythranthera brunonis) is spotted dotted around this location. They can be found growing between Israelite Bay and Kalbarri from August to early-November,
An orchid that is found on both sides of the road is the Small mantis orchid (Caladenia attingens subsp. gracillima). These are found growing between Jerramungup and Israelite Bay from August to early-October.
The wispy spider orchids from the Filamentosa complex are the next found. One specimen appears to be the Cream spider orchid (Caladenia horistes) whilst a nearly finished specimen could be the Common spider orchid (Caladenia varians). Our location is found within the recorded distribution of both species, both flower during September, plus their flowers and leaves are of similar appearance. I will leave it for you to decide if they are the same species or not.
As this area was also subject to last summer’s bushfire the next orchid found was as expected. Red Beaks (Pyrorchis nigricans) flower from August to October between Shark and Israelite Bays.
Last orchid recorded for this location is an unfurling Dancing spider orchid (Caladenia discoidea), which are found flowering from August to early-October between Kalbarri and Israelite Bay.
Location 8 is another random stop along the road. Change of vegetation so we will see if anything new is found. First orchid located was a donkey orchid, however based on only 1 specimen I will not attempt to ID it at this stage. Will share to iNaturalist for assistance in this regard
The following orchids have all been found previously today and recorded in this blog so I will post 2 pics each only to record they were found in this new location. Western tiny blue orchid, Small mantis orchid, Red Beaks, Cream spider orchid, Purple enamel orchid.
Finally, a new orchid for this blog is found. Nothing special unfortunately but something new is something new. The Cowslip orchid (Caladenia flava subsp. flava) is widely distributed between Northampton and Israelite Bay flowering from July to early-December
Just as we were heading back to Fili I spied a tall yellow orchid. Woohoo it is a new orchid for today !!!!!! The Custard orchid (Thelymitra villosa) grows to 600mm in height and can have up to 20 flowers per plant. They are found between Northampton and Israelite Bay from September to November.
What a great way to finish off this location. So, over the 2 random roadside stops we found 10 species of orchids. Sometimes it pays just to pull over and look.
Off to our final destination of the day. Refer Part IV
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
As we ventured north last trip, we decided to head west. We want to see if the species found differ in any way.
Our first stop is within the location of Coomalbidgup3.
The first orchid spied was a double-headed king spider type orchid. Identification is difficult. This is due to the recorded presence of both the Esperance king spider orchid (Caladenia decora) and the Heberle’s spider orchid (Caladenia heberleana)in this vicinity. They are also very similar in appearance.
As the later species is listed as flowering in September it is most likely the former. The dark colouring alludes to this ID as well.
A yellow-coloured orchid is the next found. The Cowslip orchid (Caladenia flava subsp. flava) is a common orchid found between Northampton and Israelite Bay.
The next orchid was found in large numbers, as it was last year in this same location. Pink fairies (Caladenia latifolia) are found flowering from August to early-December. They range from Kalbarri to Israelite Bay growing in sandy and sandy clay soils.
A single specimen of the Lort River snail orchid (Pterostylis lortensis) is spotted. It was found when walking back to the Triton, growing in the track made by illegal wood cutters. Theses orchids flower in August and September only, between Boxwood Hill and Israelite Bay.
Then back at the Triton I spied a less colourful king spider orchid. Could this one be a Heberle’s spider orchid? Please share your thoughts on the ID
Moving on we decide to check out a new location near the Coomalbidgup5 townsite. Driving, then walking, then driving, then walking we finally find some orchids. Red Beaks (Pyrorchis nigricans) is found growing in the mounded verges of the track. They flower from August to October and occur between Shark and Israelite Bays.
A few Western tiny blue orchids (Cyanicula aperta) were found spread over the site. These small blue orchids flower August to early-October between Dumbleyung and Mt Ragged.
Deb was driving and looking to the right of the track. I was walking along the left side of the track. So, as luck would have it, I came across the only specimen found of the Dancing spider orchid (Caladenia discoidea). These orchids flower August to early-October as well. Their range however is larger, Kalbarri to Israelite Bay.
Another snail orchid is also found; however, it is a different species to that found earlier. I feel we have found the Ravensthorpe snail orchid (Pterostylis grossa). These orchids are found between Millers Point and Esperance during the months of August and September.
Moving south to the west of town we find the common Cowslip orchid. A budding Purple enamel orchid is also found. None found flowering unfortunately.
Towards the end of our track, we come across some large white spider orchids in flower. From the location I will be calling them the Esperance white spider orchid (Caladenia longicauda subsp. crassa). These large orchids flower from August to early-October over the range; Bremer Bay to Cape Arid
The final orchid found at this location was an unexpected but exciting find. In a winter wet area with gravelly topsoil, we found a few buds before finding a sole flowering specimen. The Southern curly locks (Thelymitra uliginosa) is found flowering during August and September. Its range extends form Busselton to Esperance, with rare finds north to Perth.
Leaving the Coomalbidgup townsite location on a high note, we venture further west to our next Coomalbidgup6 location. Turning north up Beltana Road, we pull over on the side of the road as we see some large white spider orchids.
The first orchid photographed though is a hybrid, which is exciting. One of the parents would be the Esperance white spider orchid as we find many more of them.
Also found at this location was the Pink candy orchid (Caladenia hirta subsp. rosea). These orchids range in colour from pale to vivid pink and flower late-June to September. They occur between Kalbarri and Israelite Bay in more inland locations than the related Candy orchid.
A couple of snail orchids at the end of their season are also found. Looking at their stems I feel they may be the Hairy-stemmed snail orchid (Pterostylis setulosa). These orchids flower July to September between Nerren Nerren Station and Balladonia.
A little further up the road we spy some yellow in the bush. Upon closer inspection we are thrilled to have found some donkey orchids in flower.
From the location I will name some of these orchids the Green Range donkey orchid (Diuris littoralis). They flower from July to early-September between Denmark and Esperance. However, others could be the South coast donkey orchid (Diuris brockmanii). These flower from June to early-August between Ongerup and Esperance. These orchids have white age spots to their petals (due to earlier flowering season) and a broader labellum. Please provide your thoughts on the ID’s.
We do a U turn and head back to the Hwy. Heading west we pull some 20 metres into a track leading north, which is another Coomalbidgup7 location. Excitedly whilst having a bite to eat for lunch I spy a bird orchid alongside the track. Upon closer inspection it appears to be the Dwarf bird orchid (Pterostylis galgulus). These orchids flower in August and September between Northampton and Munglinup. This location is only 20kms east of Munglinup townsite which is an acceptable deviation.
Going further afield orchids are few and far between. Cowslip orchids are found but not in great numbers. Pictures taken for recording purposes.
Another yellow orchid is found in better numbers, though only in a restricted area at the location. The Common bee orchid (Diuris decrementum)is found singly as well as in small groups. Flowering occurs from August to early-October between Wongan Hills and Israelite Bay.
As I was walking over to Deb’s location to take pics of her many bee orchids, I stumbled across some very small leaves. Looking at the leaves more closely they appear to belong to an orchid of the Drakaea genus. EDIT: Andrew Brown has commented on my iNaturalist record that they are the non-flowering leaves of Eriochilus scaber. Thoughts
Whilst I’m busy taking pics of the bee orchids Deb finds a white spider orchid. I finally catch her up and grab some pics of what I believe to be the Esperance white spider orchid. The first orchid found appears to have had its petals and sepals nibbled. However, others found on the west side of the track have the usual long pendulous petals and sepals.
Moved on to our next stop, which ended up being 1km along Neds Corner Road. This did not prove to be very productive with only the one orchid being found. It was a very poor specimen of the Esperance king spider orchid I believe.
We did not hang around for long and moved on to our East Munglinup6 location on Farmers Road. At this spot, again only one orchid was found. This time though it was a Western tiny blue orchid.
Onto another location this time along Jonegatup Road being another new East Munglinup7 location. First up we find a few more Western tiny blue orchids.
A new orchid for the day is discovered on what appears to be the old road. The Zebra orchid (Caladenia cairnsiana)occurs between Lancelin and Esperance. Flowering during the months of August to early-November.
Snail orchids are found in various spots over this location. They appear to be more Ravensthorpe snail orchids. Pics for recording purposes. EDIT: Andrew Brown has responded to my iNaturalist record that he feels they are P. Setulosa
On a pushed-up mound we come across the Sugar orchid (Ericksonella saccharata). These orchids grow between Paynes Find and Israelite Bay during August and September. Moving back to the old road I nearly step on a snake. Scary stuff. Upon posting the pic taken on iNaturalist I can name it a Bardick (Echiopsis curta).
Spent greenhood orchids found as well, though the numerous small spider orchids are a treat. Their labellum size and the spreading habit of the petals and lateral sepals suggest they are the Cream spider orchid (Caladenia horistes). They flower between the Fitzgerald River National Park and Balladonia from August to early-October.
We have quick check of the Young River crossing before moving on to our final stop of the day.
We venture east to Neds Corner Road. We head south. Then, we make a stop on the road verge at a recently burnt area. Recorded as Coomalbidgup8 location. As with the last 2 locations, the first orchid found is the Western tiny blue orchid.
Next a single specimen of the Western wispy spider orchid (Caladenia microchila) is found. These small spider orchids flower between Kondinin and Madura from July to early-October. The relatively small labellum and stiffly held petals are distinguishing features.
Another solitary orchid is found, this one though is blue in colour. The Blue beard (Pheladenia deformis) is found between Murchison River and Israelite Bay. Flowering occurs from late-May to October.
Now the one orchid we were hoping to find in this burnt out area was the Pink bunny orchid (Eriochilus scaber subsp. scaber). Luck was on our side as we did find some small patches of them in flower. These orchids are found between Jurien Bay and Cape Arid National Park, with flowering usually after a summer bushfire. Season is from July to early-September.
Another orchid that favours a summer bushfire is the Red beaks orchid. However, we were only able to find one in bud as they only start flowering in August.
It is nearly 4.30pm so we decide to make tracks for home. Not too bad a day. We found some 21 species. We also saw leaves and buds for orchids yet to come. Plus, one possible hybrid.
After one week back at work we need to get out exploring, so as it’s Sunday we head East to Condingup to see if our Curly locks are flowering. At our townsite location we head to the location I had recorded in my Australian Geology Travel Maps app and we locate one in flower. The Southern curly-locks (Thelymitra uliginosa)is known to occur from Busselton to Esperance, flowering during August and September. It is distinguished by its spiral leaf and the more purple-coloured flowers, rather than the pinkish colour of the other curly locks species.
Further afield we stumble across the Dancing spider orchid (Caladenia discoidea) which is a distinctive spider orchid having forward projecting lateral sepals and a very broad labellum with long fringe segments. They flower between Israelite Bay and Kalbarri during late Autumn to mid Spring.
Another spider orchid found in greater numbers was the Common spider orchid (Caladenia varians) which as the name suggests has a large range from Kalbarri to East of Esperance, similar the C. discoidea mentioned previously. It flowers over a slightly longer season, July to mid-October and as its Latin name suggests is variable in appearance over its extended range.
There was a single spider orchid that has had the tips nibbled off its sepals and petals, so I initially was leaving it out of this post, however after posting it on iNaturalist it appears it is the Cream spider orchid (Caladenia horistes) which occurs between the Fitzgerald River N.P and Balladonia, flowering from August to early-October.
Other orchids found were either at the end of their season or just starting. Those ending were the Hare orchid (Leporella fimbriata) and the Scented autumn leek orchid (Prasophyllum sp. ‘early’) and the Jug orchid (Pterostylis recurva) was just starting. Flowering seasons are March to June, April to June and August to October respectively.
We now move onto our next location, Condingup Peak (Mud Map SE39) which is located in the Condingup Water Reserve. Here we find the small Fawn snail orchid (Pterostylis parva) growing in the moss on or near the granite rocks. These little orchids are found between Albany and Eyre from June to early August and are distinguished by their tiny rosette of stalked leaves, diminutive size and they become reddish with age.
The only other orchid flowering up on the peak was the Banded greenhood (Pterostylis vittata)which is found between Perth and Israelite Bay over a longer season that most other orchids, being late April through to early September.
From here we head out to our Parmango Road locations. First up we are knocked over by the number of curly locks found in flower at a patch we had not found them before. Last year we found spiral leaves so were hopeful of finding one in flower, but we found multiple. These ones included one that was pinkish in colour though it still had the usual stripes to the petals and sepals. It is possibly the Curly-locks (Thelymitra spiralis)which is also found east of Esperance during the months of August and September. The species is recorded as having pale pink petals and sepals which are unblotched.
Two others were found with blotches to the markings which may distinguish them to be the related Eastern curly-locks (Thelymitra maculata) which is also known as the Spotted curly-locks, which fits the look. They flower slightly earlier than the Southern species, however, are recorded only as far east as Ongerup, some 375km to the west of our location. Posted on iNaturalist and in the Western Australian Native Orchids FB group for assistance in identification. The responses were mixed so I will leave the ID as tentative.
Walking back to the Triton we stumble across a better Jug orchid specimen and a couple of Curly-lock pairs which may or may not be different species, due to different colouring. But the surprise find here was a good number of more Common spider orchids in flower.
Back in the Triton we move onto another location along Parmango Road where we spy more orchids. We find many orchids on the longish walk so I will group them together in species rather than chronologically. Firstly, more Southern curly-locks are found, with some showing the different shadings to the alternate petal/sepal/labellum.
Next are spider orchids from the Caladenia filamentosa complex. Telling the correct species from one another is difficult within this complex. The Common spider orchid (Caladenia varians) is the most likely to be found however the Cream spider orchid (Caladenia horistes) is another possibility as is the Western wispy spider orchid (Caladenia microchila) with all being recorded as being found this far east. You be the judge.
A change in colour is a welcome surprise. The bright yellow Common bee orchid (Diuris decrementum)is found between Wongan Hills and Israelite Bay from Aug through to October. The early flowering period is the easiest way to distinguish it from the Bee orchid (D. laxiflora) which also occurs in the same locale but does not flower until September.
A solitary Esperance white spider orchid (Caladenia longicauda subsp. crassa) is found along the track. These large orchids are found between Bremer Bay and Israelite Bay from August to October.
Another solitary orchid found appears to be a Green Range donkey orchid (Diuris littoralis) which flowers between Denmark and Esperance during July to early September. The only other possibility is the South coast donkey orchid (Diuris brockmanii) which occurs over a similar range but flowers earlier, June to early August. I will leave the positive ID to those more qualified than I.
Unsure why we are finding solo specimens, but the Bluebeard (Pheladenia deformis) is also found all by itself. This is a tiny specimen but is a nice discovery, nonetheless. This is a widespread species, ranging from Murchison River to Israelite Bay in WA, as well as being found in other states.
Leaving Parmango Road we head southwest to a granite outcrop at the Cape le Grand National Park turnoff on Merivale Road. Here we find lots of Bluebeard orchids which is nice, however it was exciting to find a new species for the day. The small Mosquito orchid (Cyrtostylis robusta) is found by searching under bushes for the distinctive round ground hugging leaf. Once you find the leaves you then take a closer look and luckily for us today, we find some in flower. These orchids flower between Perth and Israelite Bay from June to August.
Final orchid of the day is a small snail orchid. Bases on location, size and colouring I will be naming this species as the Fawn snail orchid which was found earlier today at Condingup Peak.
The east of Esperance rarely disappoints and today was no exception. At least 14 species found.
We awake to a cold morning however the sun is shining so it will be a great last day of our 2020 Road Trip. First up we check out the spider orchid we found in the fading light yesterday.
Hamersley Inlet
Western wispy spider orchid
(Caladenia microchila)
Camper packed up and time to move on. We get as far as 4 Mile Beach campground before we stop and have a scout around. We only find a few Pterostylis orchids.

Since it is after 3 pm and we still have more than 100kms to home, we decide to leave our orchid exploration at this fruitful location. The hour long drive was a great time to look back on our awesome road trip that started back on the 8th August. The Wheatbelt Way was a great loop that opened up the amazing Western Australian countryside.
Over the 3 weeks on the road we discovered many new locations as well as re-visiting favourite spots. So many orchid species were located along with numerous hybrids which was a pleasant surprise.
Leaving Esperance at just after 7am we are finally on our way. This year I will be listing the orchids found at each stop on our journey. I will group the photos of a particular orchid together rather than post them in chronological order. If needed a little narrative about the trip may be added to a location based on anything that occurred on the way to it, during the visit itself or is planned after. Please provide me any feedback on this structure as I am open to suggestions how I can improve the blog or spice it up a bit… Thanks!!
Springdale Nature Reserve
This Nature Reserve was burnt out last summer and has proven this season to be successful in providing excellent orchid finds. Today is no exception.
Turning into Mills road off the South Coast Hwy, west of Munglinup, we stop at one of our regular road verge stops. To our dismay the area had been graded so the usual orchid habitat was destroyed. Luckily some orchids seem to like disturbed ground, whilst other areas had missed the destruction.

Gorge Rock Picnic Area
Leaving Varley just after 3.15pm we make tracks for Gorge Rock, 14 kms east of Corrigin, for our overnight stay. Soup and toast for dinner then a well earned rest.
17 different orchid species found today, not too shabby.
After a wonderful night at our son’s place it is time to head off on the final day of our road trip. Leaving Ravensthorpe we make our way to Mt Desmond lookout, off Elverdton Road. Growing alongside the newly grader road to the lookout, were some small Western tiny blue orchids (Cyanicula aperta). Felt lucky to find them as the roadworks had cleared the places we had found orchids on previous visits. These little orchids are found from Dumbleyung to Mt Ragged during the period August to early-October. Also found closer to Elverdton Road was a Jug orchid (Pterostylis recurva) which is a common orchid, found flowering between Geraldton and Israelite Bay during August through October.
Moving further east, we visit another of our favourite spots, Mills Road near Munglinup. Deb finds the first of many orchids found in this location. The 4 orchids are hybrids of the Caladenia sp. Unable to positively ID so will just post some photos. I think Caladenia radialis or Caladenia brevisura may one of the parents. Please assist with ID if you can.
Found very close-by are some Zebra orchids (Caladenia cairnsiana). These small orchids flower from August to early-November in a southerly range from Lancelin to Esperance.
Intermixed with the Zebra orchids was a Short-sepaled spider orchid (Caladenia brevisura) which adds to the possibility that it is a parent of the hybrid orchids found earlier. These orchids are found between Ravensthorpe and Israelite Bay during the months of August and September.
After further exploration a sole green spider orchid was discovered. However many more were found after further searching. The Small mantis orchid (Caladenia attingens subsp. gracillima) is as the name suggests, smaller than the related Fringed mantis orchid, we found earlier in the road trip. Flowering season is August to early-October and the Small mantis orchid is found between Jerramungup and Israelite Bay,
Another spider orchid is found, this time from the filamentosa complex. The Cream spider orchid (Caladenia horistes) flowers from August to early-October between Fitzgerald River National Park and Balladonia. The Cream spider orchid is also listed as having rare hybrids with the short-sepaled spider orchid, so it may be another parent of the previously mentioned hybrids found at this site.
A single spider orchid from the same complex, but another species is found. This time the smaller Western wispy spider orchid (Caladenia microchila) is found. Smaller labellum, thinner sepals and whiter colouring provide me with this identification.
The final orchid found in this location is the small Western tiny blue orchid.
As it is only mid-morning we decide to visit Stokes National Park, before finally heading for home. Upon arriving at the campground we immediately spy some king spider orchids. One of them is a bit worse for wear with his labellum eaten out. Non damaged specimens found with variations in colour, from bright red to pale green so identifying these will be interesting, as both the Esperance king spider orchid (Caladenia decora) and Heberle’s spider orchid (Caladenia heberleana) occur in this location and they are difficult to tell apart. They may also hybridise with each other, so ID will not be attempted at this time. Lots of photos below to show my dilemma.
Well we thought there were lots of king spider orchids, but there is also as many Pink fairies (Caladenia latifolia), which flower from August to early-November between Kalbarri and Israelite Bay. Here they range in size and colour, which just adds to the thrill of finding so many.
Some Banded greenhoods (Pterostylis vittata) were also found, whilst pushing into the scrub to grab photos of the Pink fairies. Moving on, we leave the campground and drive back towards the intersection to the day area,where we had previously found orchids. We were not disappointed as we find a few Lemon-scented sun orchids (Thelymitra antennifera)in flower. These are widespread sun orchids found from Shark Bay to Israelite Bay during the months July through October.
Also found at this corner is the every popular Cowslip orchid (Caladenia flava subsp. flava) which is also a widespread orchid with a long flowering period. These ones were a bit unusual as they had white tips to the petals. Usually solid yellow with markings.
Final orchid found for the day was a unique spider orchid, which we last found at Helms Arboretum a few years back. A single Grass-leafed spider orchid (Caladenia graminifolia) is found growing in the roadside drain under the protection of overhanging banksia bushes. Found between Mt Manypeaks and Israelite Bay during August and September this orchid self pollinates so is in flower for only a few days at the most,so we are very lucky to have found one in flower.
One hour from home and nearly noon so we decide to make tracks, so we can have lunch in our own home. Mixed emotions as we remember the last 2 weeks during this last hour of our 2019 Road Trip.
The first week did not go to plan however we made up for it by visiting Margaret River and tasting a few wines. Then we had a great time catching up with friends from our Rural youth days before our 2nd week, which did not include the planned visit to Charles Darwin Reserve, however we discovered some great new un-planned locations. A special catch up with my cousin Mary-lou that included meeting the eldest cousin Ian for the first time. Only took 55 years.
The major purpose of our road trip, other than having fun getting out in the great Western Australian outdoors, is the discovery of our very special terrestrial orchids, most of which are endemic to WA. On this note we located 70 species/sub species of orchids from 10 genera, with multiple hybrids and hypochromic variants. Refer this post for their details. 2019 Road Trip – Orchids Found
So privileged to witness the natural beauty of our amazing little corner of the world!!!!!!
We wake up to a beautiful sunny spring morning. A leisurely breakfast was enjoyed as we know our destination today, so no need to rush. It’s after 9am before we finally leave Flat Rock Nature Reserve and head off in an easterly direction down the Kulin-Holt Rock Road. We reach Lake Varley and pull over on the side of the road and decide to check out the flat granite outcrop, which we later find is a part of the Lake Varley Nature Reserve.
Deb finds the first orchid growing under the scrub at the edge of the rock. The wonderful yellow donkey orchids are again flowering at the edge of the rock under the protection of the scrubs. The Western wheatbelt donkey orchid (Diuris brachyscapa) is know to grow in the region with sightings recorded in Atlas of Living Australia. Kulin shire is also one of the Local Government Areas (LGA) listed in Florabase as being a location for this orchid. Links to these resources are found via the “+” sign at the bottom of every page.
Close by some wispy spider orchids are found. Due the creamy colouring of the flowers they appear to be the Cream spider orchid (Caladenia horistes) which flowers from August to early-October over an easterly range from Fitzgerald River National Park to Balladonia, however Kulin LGA is listed in Florabase as a location for this orchid.
Another yellow orchid pops up. The wonderful Cowslip orchid (Caladenia flava subsp. flava) is such a cheerful orchid to find. Bright yellow flowers with such random markings; from spots, stripes, blotches to barely none at all. This little grouping has mainly spots. The view back to the Triton provides an indication of the habitat we are exploring.
Other orchids found were a solitary Sugar orchid (Ericksonella saccharata) and Hairy-stemmed snail orchid (Pterostylis sp. ‘inland’) . Both have vast inland ranges and flower during September.
Then a perfect specimen of the Drooping spider orchid (Caladenia radialis) is found in all it’s glory. Another inland orchid but only found from Northampton to Jerramungup, so not as widespread as the Sugar or Hairy stemmed Snail orchids.
Well now the Ant orchid (Caladenia roei) turns up to entertain us. They are said to resemble a crucifix due to the petals and lateral sepals.
Then came across more Sugar orchids and a grouping of Western wheatbelt donkey orchids before finally heading back to the Triton. Last small orchids found were the Little laughing leek orchid (Prasophyllum gracile)which were camouflaged well in the moss on the granite rock.
Time to move onto our next place to explore. We detour a slight bit to check out Holt Rock. We drive into the day use area of Holt Rock but chose not to go for an exploration, though it looks like a great place to check out another time. Further south we arrive at Varley and go check out a place on the map named Dempster Rock. After a little searching we find a track into the approximate area. Looking out our windows we are rewarded with orchids.
Some old favourites were the first found. Sugar orchids and Jug orchids (Pterostylis recurva) . Both are common orchids but always a pleasure to find.
Then the spider orchids start jumping out of the woodlands. They have strong yellow tonings and therefore appear to be the Chameleon spider orchid (Caladenia dimidia) which flowers July to September in the range Paynes Find to Norseman. My references refer to them being yellow, cream or pink-red in colour with either a small pale yellow or pale white red striped labellum. Whiter specimens are found close by.
Identifying the spider orchids is difficult given many overlap in locations and they have similar features. The Western wispy spider orchid and the Ironcaps spider orchid both also have smaller labellums than others plus the Ironcaps spider orchid also varies in colour from creamy-white to pale yellow. All three orchids are shown as being located in the Varley area in the Atlas of Living Australia.
Now we do find other orchids as well, so I will mention these ones now before adding more varied spider orchid photos. Hairy-stemmed snail orchids, Blue beards (Pheladenia deformis), Little laughing leek orchids, sugar orchids and Western wheatbelt donkey orchids are found.
The most amazing find though was a Midget greenhood (Pterostylis mutica). The reason for my amazement – is it’s height of 190mm. The tallest I have ever seen. These orchids are found in all the states of Australia which is quite amazing.
Now back to these other spider orchids. Firstly we found more Drooping spider orchids or are they? Possible hybrid with the c. dimidia as the labellum is very pale in colour with smooth margins. So I will leave the actual identification for now.
Then other spider orchids found. Some in clumps and some in isolation but all beautiful as ever. Some white, whilst others had reddish tones. Any help in naming these would be appreciated.
Getting peckish, so we finally leave this great new location and head back to Varley then down to Lake King for a meal at the tavern. After a great counter lunch and beer, we cruise further south to one of our favourite patches, Pallarup Rock. Located in the Pallarup Nature Reserve this location proves a fruitful orchid patch on most visits. Today is no exception. Within minutes we locate the first of many orchids. The Pink candy orchid (Caladenia hirta subsp. rosea) is found in many colour variations. This first one is very pale but others are bright pink.
Next up we find some donkey orchids. The Western wheatbelt donkey orchid has been recorded in the Lake Grace shire whilst the other possible orchid, the Green Range donkey orchid is recorded in the Ravensthorpe shire which is nearer the coast. The basal leaves observed are not that wide which is causing me some angst in trying to ID them, so I will just posts the pics.
We now move onto the track to the water tank and at the junction find some more Sugar orchids. Then on the side of this track the first orchids found are Frog greenhoods (Pterostylis sargentii)which was named in honour of Oswald Sargent in 1905. He was an early West Australian orchidologist and pharmacist from York, where the specimen used to name it was collected in 1904.
Moving along the track the first of the spider orchids appear. The first one is an excellent example of the wispy complex. As there is one lonely specimen I will not attempt to name it, as there are too many variables with these wispy spider orchids. It could be one of three known to this location or a hybrid between two of them.
Close by is another spider orchid, but from the White spider orchid compex this time. As the sepals and petals are not that pendulous I believe this to be the Rigid white spider orchid (Caladenia longicauda subsp. rigidula) which is found between Ravensthorpe and Israelite bay from August to October. Florabase records Lake Grace and Dundas LGA’s as also being the location of this orchid, so 50kms north of Ravensthorpe in the Lake Grace shire seems appropriate.
EDIT: With thanks to Margaret’s assistance (refer comments) the ID has been clarified as an unnamed subspecies of Caladenia longicauda. I will provide my own common name as Pallarup Rock white spider orchid (Caladenia longicauda subsp. ‘Pallarup Rocks’). Exciting to find a new subspecies.
A small blue orchid catches Deb’s eagle eye. A lone china orchid is found. This pretty blue orchid has not been found in this location on any of our numerous prior visits, so this is an exciting find. Due to the darker blue colouring, scattered calli on labellum and the location this orchid must be the Blue china orchid (Cyanicula gemmata) which has the largest range of all china orchids in WA, being from Kalbarri to Israelite Bay. Flowering period is August to early-November. The one feature that did cause me confusion with the ID was the colour of the labellum, as the mostly blue labellum conflicted with the pictures in my references, which show the labellum as being mostly white or blue striped.
EDIT: With thanks to Margaret’s assistance (refer comments) the ID has been clarified as the Granite china orchid (Cyanicula nikulinskyae) which is restricted to a range between Fitzgerald River National Park and Israelite Bay. My location is 50kms north of this coastline. Flowering period is September to early-November.
Further white spider orchids were found and their features confirm my identification as Rigid white spider orchids. Also another wispy spider orchid is found and this one appears to be the Common spider orchid (Caladenia vulgata)which as the name suggests is found over a large area, from Kalbarri to Esperance, flowering during the period July to mid-October.
Next up we come across some Ant orchids. They are also known as Clown orchid, Man orchid and Jack-in-the Box.
More yellow patches are seen growing in the Pincushion plant (Borya constricta) and Sundew (Drosera). The Lemon-scented sun orchids (Thelymitra antennifera) are another widespread orchid which flower from July to October. The latin name antennifer (antennae) refers to the little lobes on the column.
Many more spider orchids are found together with patches of Cowslips and Blue beards popping up here and there. A wonderful kaleidoscope of colours.
A relative of the Ant orchid is also found in the scrub around the rock. The Short-sepaled spider orchid (Caladenia brevisura) is a common orchid found between Ravensthorpe to Israelite Bay. We have previously found these orchids east of Esperance at Condingup so we have now found them at both edges of their range.
Other orchids found in our exploration of Pallarup Rock are the Jug orchid, Little laughing leek orchid and Hairy-stemmed snail orchid (or is it?) .
4.30 in the afternoon so time to move on to Ravensthorpe for our overnight stay. We spend our last night of our road trip as we did on our first night. Staying with our son, Timothy in his little duplex unit in Ravensthorpe.
Went to bed happy to have discovered at least 19 species today, which is amazing. Also a tinge of sadness as tomorrow is our final day.
