It appears that I ventured out to check on the late season orchids by myself as pictures taken on the Olympus E-M5 Mark II are the only record and they do not have GPS data. So, I will post the pictures and info for each orchid found with no commentary for the outing itself.

5 Different species located. From the species found I believe the location to be east of Esperance.
We check out of the York Hotel in Kalgoorlie, then say our goodbyes to Bob n Jan who are heading straight home to Esperance. Deb and I on the other hand have more orchid hunting to achieve on our return home.
First point of call is Victoria Rock Nature Reserve at 10am on this beautiful Sunday morning. For the next 2hrs or so we wander around the rock and surrounding woodland. The flies are terrible, so we actually wear our head nets on this exploration. We are rewarded for our perseverance with some good orchids found.
In no particular order the following orchids were located and photographed:
Little laughing leek orchid (Prasophyllum gracile), Dainty brown rufous greenhood (Pterostylis tryphera), Desert mignonette orchid (Microtis eremicola), Ant / Clown orchid (Caladenia roei), Yellow granite donkey orchid (Diuris hazeliae), Lemon-scented sun orchid (Thelymitra antennifera) and Granite sun orchid (Thelymitra petrophila).
Numerous hybrid orchids were an exciting find. Parents are the Lemon-scented sun orchid and the Granite sun orchid, both of which have been found at this location.
Thelymitra antennifera x T. petrophila (Yet to fully open)Thelymitra antennifera x T. petrophila (Inverted flower)
Onwards to our next location, we head south down Victoria Rock Road and turn left onto the Hyden-Norseman Road. Upon reaching the Coolgardie-Esperance we make a right turn, then pass through Norseman. Our next location, Bromus Dam is to the right of the highway some 30kms south of Norseman. We head straight for the McPherson’s Rocks granite outcrop and start our exploration.
We are fortunate to find the following orchids in flower:
We need to keep on moving closer to home, so we make tracks south along the highway as far as Circle Valley to check out the woodlands surrounding the salt lakes. Here we find the Short-sepaled spider orchid (Caladenia brevisura) in good numbers with one lonely Midget greenhood (Pterostylis mutica) and a all but spent spider orchid (ID unknown).
Well, that is our final stop on the Pub Crawl road trip done and dusted.
Our trip with Bob n Jan started back on the 7th of September. We stayed overnight in some interesting pubs: Newdegate Hotel Kukerin Community Hub Cuballing Tavern Hotel Beverley Greenhills Inn Koorda Hotel Palace Hotel – Southern Cross York Hotel – Kalgoorlie
After a restful sleep we grab breakfast at the local cafe, the Southern Star Cafe. Then we again hit the road. Bob and Jan head off for Coolgardie, whilst we use good old Google Maps to find a possible orchid location. Condarnin Rock Nature Reserve is chosen. We take the road south just after the burnt out Yellowdine Roadhouse. It turned out to be a good choice as we discovered the following orchids: Narrow-lipped dragon orchid (Caladenia mesocera), Clown / Ant orchid (Caladenia roei), Dainty blue orchid (Cyanicula amplexans), Spoon-lipped rufous greenhood (Pterostylis spathulata), Yellow granite donkey orchid (Diuris hazeliae), Lemon-scented sun orchid (Thelymitra antennifera), Granite sun orchid (Thelymitra petrophila), Little frog greenhood (Pterostylis occulta) and Little laughing leek orchid (Prasophyllum gracile).
Numerous spider orchids from the Filamentosa complex were also found. I however find identifying these orchids very difficult so will provide my options for the species names and pictures of the orchids. Any assistance in naming these would be greatly appreciated. I have also posted then on iNaturalist for similar assistance.
Breakfast in Koorda before we head east toward Mukinbudin, where we make our first orchid hunting stop at Wundowlin Nature Reserve. Orchids discovered at this location include: Lemon-scented sun orchid (Thelymitra antennifera), Dainty blue orchid (Cyanicula amplexans), Little laughing leek orchid (Prasophyllum gracile) and Chameleon spider orchid (Caladenia dimidia).
Passing through Mukinbudin we come across an amazing mural featuring black cockatoos and Blue beard orchids, painted by Tammi de Rooy @tammiderooyart, which by the way is the feature image of this post. Next, we head southeast towards Westonia.
On the way we make another orchid hunting stop at Boodallin Soak located in the Westonia Common. After a quick check of the well Bob n Jan head into Westonia for an explore whilst we explore the granite outcrop. Orchids found include: Yellow granite donkey orchid (Diuris hazeliae), Little laughing leek orchid, Western wispy spider orchid (Caladenia microchila), Midget greenhood (Pterostylis mutica), Dainty blue orchid, Slender rufous greenhood (Pterostylis macrosceles) and Pink candy orchid (Caladenia hirta subsp. rosea).
After arriving in Westonia we enjoy lunch with Bob and Jan at the Cafe/Supermarket. They then go to check out the museum whilst we explore the Woodlands & Wildflowers Heritage Trail for orchids. This walk trail is also contained in the Westonia Common. Orchids found include: Dainty blue orchid with an Albino form found, Little laughing leek orchid, Ant / Clown orchid (Caladenia roei), Granite sun orchid (Thelymitra petrophila), Spoon-lipped rufous greenhood (Pterostylis spathulata) and Spider orchids of the Filamentosa complex. Unable to identify with a high probability of correctness, so have posted 4 pics of the various forms found.
Nearly 3pm so we had better keep moving. We hit the Great Eastern Hwy and venture eastward as far as Bodallin1 where we make another exploration stop. Many more Filamentosa complex spider orchids are found. I’ll not attempt to name them, but I’ll use iNaturalist.com for assistance and make edits as needed. Other than C. microchila and C. dimidia already listed today other possible species are: Glistening spider orchid (Caladenia incensum), Banded Ironstone spider orchid (Caladenia saxicola), Common spider orchid (Caladenia varians).
Other orchids found include the Dainty blue orchid, Ant / Clown orchid, Little laughing leek orchid, Yellow granite donkey orchid, Hairy-stemmed snail orchid (Pterostylis setulosa), and Little frog greenhood (Pterostylis occulta).
It is nearly 4pm so we move onto our next overnight accommodation, where we again catch up with Jan and Bob. The Palace Hotel in Southern Cross was a comfortable hotel with great meals. We hit the sack content.
After enjoying our hotel breakfast, we leave Newdegate and head towards Dragon Rocks Nature Reserve. Numerous stops are made along the track and then we explore the camping area which includes the flat granite rocks.
First orchid found was the Sugar orchid (Ericksonella saccharata), then further along the track a possible Dwarf zebra orchid (Caladenia pachychila) is found. Open to correction on this one. Other common orchids found along the way include the: Purple enamel orchid (Elythranthera brunonis), Western tiny blue orchid (Cyanicula aperta), Western wheatbelt donkey orchid (Diuris brachyscapa) Dancing spider orchid (Caladenia discoidea).
Along the track in we also come across our first standard looking spider orchids. Again, like yesterday I feel they are all variations of the Chameleon spider orchid (Caladenia dimidia).
Further common orchids were found at the flat granite outcrop area, including the Cowslip orchid (Caladenia flava subsp. flava), Pink candy orchid (Caladenia hirta subsp. rosea) and the Ant orchid (Caladenia roei).
Also found along the way was the Little laughing leek orchid (Prasophyllum gracile) and 2 Pterostylis orchids from different complexes. One is a spent orchid from the Vittata complex and the other is a budding orchid from the Rufa complex. Naming these is not possible.
Now onwards to our next stop, which was an unplanned stop at the intersection of Kulin-Holt Rock Road, where we found a memorial of the Holland Track, so pulled in for a photo op. Also took the opportunity to quickly explore the verge side vegetation for any orchids. Actually, found some including the Jug orchid (Pterostylis recurva) and more Chameleon spider orchids.
Pterostylis recurvaCaladenia dimidia
Heading west along the Kulin-Holt Rock Road we come to our planned lunch stop, Buckley’s Breakaway, which is located in the Un-named Nature Reserve No. WA27485. After a bite to eat we venture along the trail into the breakaways, which are an amazingly site. (Refer feature image)
Of course, our eyes are looking for orchids as we stroll along. We are not disappointed as we first come across the Sugar orchid, followed by the Frog greenhood (Pterostylis sargentii) and an unknown Banded greenhood (Pterostylis sp.). I originally identified this as the Mallee banded greenhood (P. arbuscula) however it is listed as flowering in early winter so it may just be a short specimen of the Dark banded greenhood (P. sanguinea)which does flower into September and is also listed as occurring in this vicinity. Please provide comments to assist with the ID.
On the return journey 2 more orchids are found. The Brittle snail orchid (Pterostylis timothyi) and more Western wheatbelt donkey orchids.
Pterostylis timothyiDiuris brachtscapa
We move on towards Kukerin our planned overnight hotel stay. However, we first make a planned orchid hunt and bush walk at a spot called The Jam Patch, which is located at the old North Lake Grace tennis club.
Orchids found that had been found earlier today include the: Pink candy orchid, Western wheatbelt spider orchid, Little laughing leek orchid, Chameleon spider orchid.
New orchids for the day include the: Salt lake spider orchid (Caladenia exilis subsp. exilis)* Cream spider orchid (Caladenia horistes)* Yellow granite donkey orchid (Diuris hazeliae)* Drooping spider orchid (Caladenia radialis), Possible hybrid, parents unknown (Caladenia x)*
Orchids marked with * may not be separate species, possibly just C. dimidia, D. brachyscapa, or C. radialis so please correct me in the comments section if so.
Today is the day that our Pub Crawl around the Southeast of WA commences. We head off in the Triton around 8.45 am and venture over to Nulsen to pick up our travelling companions for the adventure, Bob and Jan. First stop is at the Munglinup1 Roadhouse, where I take the time to have a very quick check for orchids.
8 species are found, which is quite unbelievable. First up, the reliable Cowslip orchid (Caladenia flava subsp. flava) is found. Next is a large white spider orchid, which, given its location, I will name the Esperance white spider orchid (Caladenia longicauda subsp. crassa). Thirdly is one of the smaller spider orchids from the Filamentosa complex. It is most likely the Common spider orchid (Caladenia varians). Next is the small Zebra orchid (Caladenia cairnsiana). The 5th orchid found is the Lemon-scented sun orchid (Thelymitra antennifera). A not fully opened Purple enamel orchid (Elythranthera brunonis) is found next. The 7th orchid for the day is the Dancing spider orchid (Caladenia discoidea). Final and 8th orchid for this location is the Small mantis orchid (Caladenia attingens subsp. gracillima).
We now move on to the lookout on Ethel Daw Drive in the Ravensthorpe shire. Only 2 species were found along the roadside. First up is the Western tiny blue orchid (Cyanicula aperta),followed by the Sugar orchid (Ericksonella saccharata).
Cyanicula apertaEricksonella saccharata
Moving back to Elverdton Road, we head west and pull into a new location I will name Ravensthorpe1. Walking along this dirt track, we locate 4 species, 1 new for the day. Found again were the Small mantis orchid, Sugar orchid and Western tiny blue orchid. The new species for the day is the Common dragon orchid (Caladenia barbarossa). Terrible pictures were taken, so I will include only 2.
Passing through Ravensthorpe, will pull into Kukernup Memorial to have lunch. After having a bite to eat, we all venture out to explore the walk trail. It was a great spot, as we found 9 orchid species in flower. First up is the Jug orchid (Pterostylis recurva), Next, more Dancing spider orchids and Common dragon orchids are found. Also found again were more Small mantis orchids, Lemon-scented sun orchids, Cowslip orchids and Purple enamel orchids. Other new species found for the day are the Redbeak (Pyrorchis nigricans) and the Frog greenhood (Pterostylis sargentii).
We now backtrack to the road leading to Lake King and head north. Next stop is one of our all-time favourite places. Pallarup Rocks picnic area provides loads of places to explore for orchids. We are not disappointed with the species located. First up are the Sugar orchid, Cowslip orchid, Jug orchid, Purple enamel orchid, and Lemon-scented sun orchid, which were all found earlier today at prior locations.
New species found start with the Ant orchid (Caladenia roei), quickly followed by the closely related Short-sepaled spider orchid (Caladenia brevisura)and Purple-veined spider orchid (Caladenia doutchiae).
The next new species found for the day was the Pink candy orchid(Caladenia hirta subsp. rosea) together with its hybrid – Tinged spider orchid(Caladenia x suffusa). So, now to find the other possible parent of the hybrid. Due to the location, I believe the other parent to be the Pallarup white spider orchid (Caladenia longicauda subsp. ‘Pallarup’). Luckily specimens are found.
Caladenia hirta subsp. roseaCaladenia x suffusaCaladenia longicauda subsp. ‘Pallarup’
Once up on the granite rock we come across some donkey orchids. I believe them to be the Yellow granite donkey orchid (Diuris hazeliae). I have posted images of 3 orchids as they may represent another species.
Diuris hazeliaeDiuris sp.Diuris sp.
A smaller whiteish spider orchid is found in various shades, however I feel they are all the Chameleon spider orchid (Caladenia dimidia).
Do you agree they are all one species?
Also found a nice bunch of what appears to be another orchid species, possibly the Central wheatbelt spider orchid (Caladenia sp. ‘central wheatbelt’) however is outside of the recorded location.
Another frog greenhood is found however on closer inspection; it is actually a Little frog greenhood (Pterostylis occulta)due to the hairy narrow horn-like labellum structures. 2 pics posted to show this aspect as clearly as possible
Pterostylis occultaPterostylis occulta
Another new orchid for the day is the Little laughing leek orchid (Prasophyllum gracile) which is found growing in shallow soil on the granite.
Other random hybrids are found during the search, and I will post them below for record keeping. Assigning parents is always difficult for hybrids especially between the Roei and Filamentosa complexes.

Well that is our final orchid stop for the day, so it is off to our first hotel stay. Night 1 is spent at the Newdegate Hotel. Checked out the Silo Art before settling in for the night.
Newdegate SilosNewdegate Hotel
23 species found with a possible 4 hybrids, plus a possible new species but outside its usual range.
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
A beautiful Sunday afternoon in Esperance so what better way to spend it than looking for orchids. Where to go today though? Let’s hit some coastal and near coastal locations to see what we find.
First stop is a coastal Esperance location10
Walking around the marked trail from the car park Deb spies some Snail orchids growing in the scrub. These small orchids appear to be the Southern thick-sepaled snail orchid (Pterostylis meridionalis). They are found in coastal locations between Stokes Inlet and Cape Arid. Flowering from July to September in coastal woodlands and shrublands. If my ID is correct this is only the 2nd time, we have found these, which is exciting.
20-100mm in heightBloated appearanceSlightly apically thickened lateral sepalsGreen and white flowers4-6 basal rosette leaves and 3-4 cauline leavesBroadly flared petals
We now head down the dirt track to toward the granite headland. In the scrubby raised edges to the path, we are pleased to find some helmet orchids. These ones appear to be the Sand hill helmet orchid (Corysanthes despectans)which is found between Bunbury and Israelite Bay. They flower from July to early-September and grow in sandy soils in coastal woodlands and shrublands. They also occur in SA, Vic and Tas.
Now this is a newly discovered species for us so really excited.
Dorsal sepal does not form a hood over labellumLarge, incurved labellumSide on perspectiveBirdseye viewSimilar colouring to Crystal Helmet Orchid (C. limpida)Stand 9-15mm in height when floweringMany leaves but few flowersGreen, rounded, ground hugging leaf
Further down the track we come across more rounded leaves. These leaves, however, end up belonging to the Mosquito orchid (Cyrtostylis robusta). This is a widespread orchid which occurs between Perth and Israelite Bay. These flower earlier so are nearing the end of their season, being June to August.
Thin spreading petalsGreen ground hugging leafUp to 8 flowers per plantFull plant shot
At the end of the track/s before reaching the granite another species of snail orchid is found. This one is likely to be the Eastern granite snail orchid (Pterostylis voigtii) which flowers from July to September. It occurs between Stokes Inlet and Cape Arid, growing in shallow soil pockets over granite.
20-100mm in heightShortish lateral sepals1 or 2 cauline leavesFlared petalsNice hood of snailsRosette of 4 to 6 leaves
Moving onto another coastal location 11 . Here we first find some more snail orchids. Some had the slight clubbing to the lateral sepals whilst others did not. I believe the former are Southern thick-sepaled snail orchids whilst the later are Eastern granite snail orchids. Pics of both recorded.
Deb is excited to find a shell orchid. From the location of the orchid, I believe it to be the Curled-tongue shell orchid (Pterostylis rogersii). These orchids flower from June to August between Binningup and Esperance in coastal woodlands and shrublands. Another one is found nearby which is greener in colour but appears to be the same species.
Stands only 70-100mm in heightThe more common brown coloured formThe rarer green coloured formProminent hairy curved labellumWhite striped flowersObvious “Common name”
An orchid found in various shades was the Pink fairies (Caladenia latifolia). A common orchid found between Kalbarri and Israelite Bay, flowering during the months August to December.
Can grow up to 450mm in height50 Shades of pink: Pale to ….50 Shades of pink: … to BrightCommon name alludes to the winged labellum and column resembling a fairySide view showing upright dorsal sepal
Another 3 species of orchid are also found. 1 of which have been found previously today: The Mosquito orchid. Newly found are the rosette of a Bird orchid and the Banded greenhood (Pterostylis vittata). Pictures taken for future reference.

Moving onto our third location for the day.12 Here a quick inspection turns up some more Curled-tongue shell orchids.
Labellum protrudes giving the common nameLong thin upright lateral sepalsBrown or green and white striped flowers
Last location of the day provides wonderful views over Pink Lake. 13 Here we are amazed to find the Beautiful donkey orchid (Diuris pulchella) growing so close to the coast. I believed it was an inland orchid as it’s range is listed as being between Salmon Gums and Israelite Bay. These stunning orchids flower from July to September.
Broadly-oval to rounded petalsNarrow, often crossed lateral sepalsSide view. Lateral sepals not crossed this timeRelatively short mid lobe to labellumBright yellow and mauve flowers
Another less colourful donkey orchid is also found. Due to our location, I believe this to be the Green Range donkey orchid (Diuris littoralis). Florabase’s map indicates they can occur in coastal locations. Also, their range is listed in my orchid books as being between Denmark and Esperance. The flowering season is July to early-September so it all fits.
Narrow, often crossed lateral sepals. though not is this case.Yellow, brown and mauve flowersOblong to elliptic petalsBroad dorsal sepalRange in height from 180 – 300mmTri-lobed labellumUp to six flowers per orchid
Further along the track we come across some more Pink fairies. These ones seem to be pink and white striped which is interesting. Also found a lone Snail orchid, ID unknown. Pics take for recording purposes.

The final orchids found for the day were the large white spider orchids. I now need to decide if they are all the Esperance white spider orchid (Caladenia longicauda subsp. crassa) or maybe different species. What are your thoughts?
We spend several hours exploring our coastal and near coastal locations. Then, we return home happy as we have located so many different types of orchids.
The Sand hill helmet orchid being the find of the day.
I’ll finish this post with one of the beautiful scenes we enjoyed today…
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.
