A camping trip on the coast at Alexander Bay, east of Esperance, provides our first orchids of the season. Within metres of the water the early flowering White bunny orchid (Eriochilus dilatatus subsp. dilatatus) is found. These orchids are found from Lancelin to Israelite Bay during April and May. They can grow up to 350mm in height and can have as many as 10 flowers. Their colouring is listed as white, dull green and red. Finding these small delicate flowers flowers growing so close to the water was amazing. The strong winds and sea spray they endure is a test of their resilience.
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.
Earlier this month we ventured east of Esperance, so today we have decided to try the west side of Esperance. It is a few weeks later into the orchid season in Western Australia so we are hopeful of finding many orchids in flower. First up we check out a recently burnt section of bush near Coomalbidgup. We find so many orchids here that it is over 1hr later before we move on.

Moving on we head west and call into an area, that had also been recently burnt, along the South Coast Hwy, near Neds Corner Road. At the first spot chosen we ventured far and wide and came across orchids in large colonies as well as isolated individuals. We found some species which were found at the Coomalbidgup location as well as some new species for the day.

So, it turned out to be a great Sunday drive where we discovered at least 16 species of orchid. A first for us west of Esperance was the Southern curly-locks, which we have only found east of Esperance previously. Finding the small Pink bunny orchid at numerous locations was our highlight of the day.
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.
What better reason to travel up to Perth and Dwellingup than to help to celebrate 2 milestone birthdays. This will be the first road trip in my new car, a hybrid Toyota Corolla I have named Fili, due to its red colouring matching the Blood spider orchid (Caladenia filifera).
FILI – My new Hybrid Toyota Corolla – Pit stop in Corrigin
Travelled up Friday by taking another RDO, which gives us time to make a quick orchid stop, firstly near Corrigin (Mud Map E12). Not a very successful location this early in the season with only 1 bunny orchid found. Given the location and the small stem leaf I will name this one the Blunt-leaved bunny orchid (Eriochilus dilatatus subsp. brevifolius), which flowers April to June over a range from Murchison River to Toolina Cove, as previous subspecies orientalis and undulatus have now been combined into brevifolius. Refer this BioOne article.
One other location checked quickly was Williams Road where we found a shell orchid in bud; most likely the Red-veined shell orchid (Pterostylis hamiltonii) which flowers late May to early August over an inland range from Toodyay to Stirling Range.
Now to get to Perth for the 60th Birthday Party for a High School and Youth Club friend, Kim. Next morning, Saturday the 13th we head up to Dwellingup to catch up with my sister Lorraine and her family, who was celebrating her 70th birthday by having a weekend away. As the road bridge over the Murray River was closed for repairs we parked on the North bank and walked over and then onto Nanga Bush Camp where my sister and family were staying. After enjoying a wonderful Birthday breakfast, we said our goodbyes and got drenched on the walk back to our cars due to a freak rain shower. Welcome back to Dwellingup 🙂
Back in Dwellingup we pop up to the Forest Discovery Centre to say hello to Megan, my niece and it is in the carpark we find some bunny orchids. It was fun showing people these unusual small orchids for the first time. The orchids found are now known as the White bunny orchid (Eriochilus dilatatus subsp. dilatatus) as per the beforementioned article on BioOne. Subspecies magnus and multiflorus, which these orchids would have most likely have been identified as, have been absorbed by dilatatus.
We spend the afternoon with Geoff and Robyn and sister; Maxine which leads into an evening catch-up and sleepover. Next morning, we make the start of our long drive home to Esperance. Only one orchid hunt is completed on this leg and that is checking a location near Hyden for the elusive Winter spider orchid. No luck with them but we did find some more bunny orchids. This time round they appear to be the now defunct Crinkle-leafed bunny orchid (Eriochilus dilatatus subsp. undulatus)which is now subsp. brevifolius as per the previously mentioned article.
It was a great weekend catching up with family and friends and being there to celebrate Kim’s 60th and Lorraine’s 70th birthdays. Orchid wise not so great, but we did find some.
IMPORTANT NOTE It was only when writing this blog in Jan 2024 that I realized Florabase had removed the following subspecies from the dilatatus group: magnus, multiflorus, orientalis and undulatus. Only 2 subspecies remain: dilatatus and brevifolius. I then checked online and found the BioOne article dated 16/04/2020, which advises which subspecies were combined. I have now named my orchids based on this change. My latest reference book: The Complete Orchids of Western Australia (Andrew Brown) however still includes a total of 8 subspecies, which adds to confusion with Identification.
I have an RDO, and the grandkids are enjoying the last few days of school holidays, so why not give mum a break and spend the day with Grandad and Nana. So, we take them off on an afternoon orchid hunt of sorts. First up it’s time to play on the blue metal mounds in our first location, a bit north up the Coolgardie-Esperance Highway.
No orchids seen on the drive into and out of this location, so we move on to Mount Burdett where we take the kids on a mountain climb. Well calling this casual bush bash and granite rock ramble a mountain climb is a bit of a stretch, but it was a good workout, nonetheless. Plus, the bonus was finding some orchids.
Actually, the first orchid blew my mind, as it was a bunny orchid with 16 flowers in its inflorescence. For this location, the White bunny orchid (Eriochilus dilatatus subsp. dilatatus) or the Granite bunny orchid (Eriochilus pulchellus) are the most likely species to be encountered. Neither are listed with 16 flowers; however, the Granite bunny is listed as having up to 10, whilst the White bunny has up to 7 and in rare cases 10. I have posted pics onto iNaturalist Australia site for assistance in identifying the probable species.
At and near the summit of the hill we come across some other bunny orchids in flower. These orchids are growing on the granite, have fewer flowers and a thick stem, which leads me to name these one’s the Granite bunny orchid.
Before leaving the rock, we grab a couple of pics then head back down to the Triton where we have afternoon tea before for the drive home. On a roadside stop we find another bunny orchid, which I will not attempt to ID as I did not grab a photo of its leaf.
What better way to spend my RDO than in the company of my beautiful partner in crime Debbie and 2 of our gorgeous grandchildren, exploring for early season orchids. The amazing warm, sunny weather was the icing on the cake.
This time we have lunch rather than breakfast at the Esperance Bird and Animal Park. We enjoy the company of friends, Kim and Linda and I enjoy a beer 🙂 After a pleasant catch-up Deb and I decide to go check out one of our favourite orchid haunts, Helms Arboretum (Mud Map SE35). We are hunting the early season species such as the white bunnies, hare and leafless orchids.
After spending around an hour checking various locations, we struck out with the hare and leafless orchids, zero found 🙁
We did however find a few White bunny orchids (Eriochilus dilatatus subsp. dilatatus) in flower. These small orchids commence flowering in April and continue into May over a large coastal range from Lancelin to Israelite Bay. The labellum is usually a cream colour with purple markings, that can range in vividness to almost non-existence.
White bunny orchid (Eriochilus dilatatus subsp. dilatatus)
Breakfast enjoyed at the Esperance Bird and Animal Park with my sister Lorraine, brother in-law Ken and Tim, Tian and kids. It was then time to show L&K the Helms Arboretum orchids. Well, the one’s flowering in late October that is.
It has been raining so the orchids are covered in drops of water which makes for some great pictures. First up we find the small but colourful Elegant donkey orchid (Diuris concinna) which flowers from September to early December between Bremer Bay and Cap Arid.
Forward projecting lateral sepals hidden under labellum
Tapering dorsal sepal
Up to 400mm in height
Up to 5 flowers per orchid
Covered in water droplets
Also, very excited to find some orchids without any colouring other than yellow. These are likely to be lutea or hypochromic versions of the Elegant donkey orchid, as the visually similar Little Esperance bee orchid is listed as a very rare orchid, so is unlikely to be found at Helms.
Tapered dorsal sepal
Elongated petals
Forward projecting lateral sepals hidden under labellum.
Up to 5 flowers per orchid
Due to the damp and overcast weather the sun orchids are barely open. Firstly, the Leopard orchid (Thelymitra benthamiana) is found. These orchids flower from September to November between Northampton and Israelite Bay. Next is most likely the Scented sun orchid, however as I overlooked taking photos of the leaf, positive ID will not be possible.

Other random orchids found include the Purple enamel orchid (Elythranthera brunonis) which flowers August to early November between Kalbarri and Israelite Bay; the Rattle beaks (Lyperanthus serratus)which flower September to November between Perth and Israelite Bay; and the White fairy orchid (Caladenia marginata) which flowers late September to November between Juien Bay and you guessed it, Israelite Bay.

Then last but definitely not least, we locate some spider orchids. The Esperance white spider orchid (Caladenia longicauda subsp. crassa) is still found in fairly good numbers, given they are recorded as flowering August to early October. The other orchid is the Esperance king spider orchid (Caladenia decora) which flowers mid-August to October. Both orchids are recorded as occurring from Bremer Bay to as far east as Israelite Bay and Cape Arid respectively.

With at least eight species located it turned out to be quite a successful hunt. Oh, I would love for the yellow orchids to be the Little Esperance bee orchid, however I would require a better person than myself to name them that. However even if they are just a single-coloured variety of D. concinna, that will still be fine. Tomorrow, we head north.
Upon leaving the Jerramungup burnt are we head east looking for somewhere to park up for the night. We make it about 35kms when we pull into the Jacup Highway Park at the Fitzgerald River crossing. This will do, so we set up the camper and I do my best to drive over a log in my Ford Falcon, not the greatest idea 🙂 I’ve had.
Now we still have the late afternoon to go orchid hunting. As per our previous visit to this location, we are not disappointed. First, we find the Green spider/Fringed mantis orchid (Caladenia falcata) flowering in isolation and in small groups over the entire area we checked out.
Calli extend to mid lobe only
Clubbed sepals
Parent and hybrid child
As can be seen in the picture above the hybrid, Wheatbelt spider orchid (Caladenia x cala) was also found. It was amazing how many were actually found, as we usually find one or two only in each location.
Attractive hybrid
Red hockey stick shaped calli
Regularly found in twins
Standing up to 400mm in height
Long fringe segments to greenish-white, red-tipped labellum
Long pendulous lateral sepals
Another parent and hybrid child
And of course, we also found the other parent for the hybrid. The Stark white spider orchid (Caladenia longicauda subsp. eminens) occurs as far east as Ravensthorpe and grows in open woodlands so seems to fit the bill.
Broad labellum
Broad bases to lateral sepals
May be found in tight groups
Bright white in colour
Labellum yet to curl under
Next, we find the very special Lazy spider orchid (Caladenia multiclavia) which is recorded as occurring between Wongan Hills, Borden and Ravensthorpe. This unusual looking orchid is known for its upright petals and sepals plus the smooth striped labellum with a dense band of bristly headed calli.
Tied up with cobwebs
All sepals and petals held upright
Horizontally held flowers.

We also come across a mixture of other orchids but not in great numbers, so I will record then with only 1 pic each. Firstly, there is the ever-reliable Cowslip orchid (Caladenia flava subsp. flava) and Common mignonette orchid (Microtis media subsp. media). Both are common, widespread orchids. Then the more rarely found, without a recent summer fire, Red Beaks (Pyrorchis nigricans) is discovered with a nine-flower inflorescence. Finally, a pale coloured Pink candy orchid (Caladenia hirta subsp. rosea) and possibly a Ravensthorpe rufous greenhood (Pterostylis leptochila) yet to fully flower are found.
Cowslip orchid (Caladenia flava subsp. flava)
Common mignonette orchid (Microtis media subsp. media)
One orchid not expected was the Common dragon orchid (Caladenia barbarossa)which is found flowering between Bindoon and Munglinup. There are only 4 species of dragon orchids, and all are endemic to WA. Only 2 specimens found but still very happy.
Column overlooks the large major callus

However, one final orchid is found in decent numbers. The Drooping spider orchid (Caladenia radialis), is found flowering between Northampton and Ravensthorpe from August to October. The labellum can have smooth margins or tiny marginal teeth.
Drooping petals and lateral sepals
Dorsal sepal can be held erect.
Two distinct bands of calli

Back to camp due to the fading light.
Small campfire lit
We awake to a beautiful sunny morning, have breakfast then decide we will take some time this morning to complete a search down to the river. Fingers crossed for something new.
First up though I will post pictures of those orchids we come across that we also found in our afternoon search yesterday.

Now for the new findings of the location. The Short-sepaled spider orchid (Caladenia brevisura) is found between Jerramungup and Israelite Bay from August to October. Only one specimen found, and not the best picture, but a record non the less. Another sole specimen found was that of the Bee orchid (Diuris laxiflora) which flowers September to early November between Gingin and Esperance.

Blue sun orchids are found in good numbers closer to the river. Now identifying them is needed. As I am writing this account over 12mth later I am identifying them from pictures taken. Based on these I feel some to be Scented sun orchid (Thelymitra macrophylla) due to the broad leaf and large numerous flowers. Others though have thin leaves with fewer flowers, so are most likely the Shy sun orchid (Thelymitra graminea). Both are recorded as flowering in the Shires of Ravensthorpe and Jerramungup during the month of October.

It is 11am so we had better push on as we need to arrive home in Esperance today. One last stop is made at Kukenarup Memorial, where we enjoy a spot of lunch before one last exploration for orchids.
