Top Orchids Found West of Esperance: A Field Report; Part IV

04/09/2024

Well, this has proven to be a full-on day trip looking for orchids. The last stop for the day is an East Munglinup location, though this time it’s on Jonegatup Road.

The first orchid found is the Small mantis orchid (Caladenia attingens subsp. gracillima), which has been a common orchid at various locations today.
Flowering occurs from August to October in woodlands and shrublands between Jerramungup and Israelite Bay.

Whilst capturing a photo of the Small mantis orchid, another smaller orchid is spied. Another better example is found soon after.
The Little frog greenhood (Pterostylis occulta) is found between Northampton and Ravensthorpe from late-August to October.
Our location is some 80kms to the east of Ravensthorpe, so a slight extension to its range.

Further along, a couple of specimens of the Zebra orchid (Caladenia cairnsiana) are found.
These small orchids occur between Lancelin and Esperance from August to early-November.

It was amazing to catch 2 species of orchids growing together. The Small mantis orchid was found under the watchful eye of the Common dragon orchid (Caladenia barbarossa).
The dragon orchid is found growing between Bindoon and Esperance from September to mid-November.

Appears to be the location for Caladenia species. Next up, we find the Short-sepaled spider orchid (Caladenia brevisura).
These orchids are found between Jerramungup and Israelite Bay during August and September.

5 other species were also spotted at this location.
4 were solo specimens:
Little laughing leek orchid (Prasophyllum gracile)
Sugar orchid (Ericksonella saccharata)
Western tiny blue orchid (Cyanicula aperta)
Common spider orchid (Caladenia varians)

Lastly was the Lemon-scented sun orchid (Thelymitra antennifera), which was found in a group, though not yet fully open.

So, our day trip finally comes to an end. We now need to drive the 112 kms home, but we do so with a sense of achievement.
This final location turned up 10 different orchid species, whilst over the whole day, we discovered at least 27 orchid species and at least 1 hybrid.
What a Day !!!!!

Top Orchids Found West of Esperance: A Field Report; Part II

Day Trip, Western Australian Orchids

04/09/2024

After a wonderful morning finding 15 species of orchids over numerous locations, we pull off the road to park up and enjoy lunch, from the boot of my small Toyota Corolla (Fili).
Neds Corner Rd is the border between the locations of Coomalbidgup and East Munglinup.
So, our lunch is in East Munglinup⁸, being West of the road however our explorations take us to the East side as well, which technically is in Coomalbidgup.
Not too confusing I trust. 🙂

After lunch we hit the surrounding area for another orchid hunt. Very close by we find our first orchids for the afternoon.
The Zebra orchid (Caladenia cairnsiana) is found growing between Lancelin and Esperance from August to early-November.

Red beaks (Pyrorchis nigricans) are usually found flowering the season after a summer fire has burnt its habitat. This is the case with this location, and they are found in great numbers.
Occur between Shark Bay and Israelite Bay from August to October.

Another orchid previously found today is also located at both sides of the road. The Small mantis orchid (Caladenia attingens subsp. gracillima) is found between Jerramungup and Israelite Bay during the period August to early-October.

A newbie for the day was next on the list. The tiny Little laughing leek orchid (Prasophyllum gracile) occurs between Shark Bay and Eyre during the period July to November.

An orchid which we always expect to find, but on occasions we are disappointed is the Cowslip orchid (Caladenia flava subsp. flava). Today we are not disappointed. In fact, we find hundreds growing on the banks of the Young River in the unburnt vegetation, whilst earlier we found sporadic ones growing in the bushfire zone.

In a bushfire regrowth area green with weeds and white sandy soil we find a great patch of the Esperance king spider orchid (Caladenia decora). These orchids range from Bremer Bay to Cape Arid from mis-August to October.

Another newbie and a surprise for the day is the Pink candy orchid (Caladenia hirta subsp. rosea) which occurs between Kalbarri and Israelite Bay from late-June to September.

Intermixed with the Cowslips was another yellow-coloured orchid. The Lemon-scented sun orchid (Thelymitra antennifera) is found between Shark and Israelite Bays from July to October.

As would be expected orchids found earlier today will also be found at this location being only 10km or so north. So further specimens of the Purple enamel orchid (Elythranthera brunonis) are found as they occur between Kalbarri and Israelite Bay from August to early-November.

A single king type spider orchid is found which does not appear to be the Esperance king spider orchid.
Due to the lack of red colouring and the drooping petals I will name this the Heberle’s spider orchid (Caladenia heberleana). These orchids are listed as occurring between Augusta and Cape Arid during September and October.
I have posted this ID on iNaturalist and will await other opinions.

Another solitary specimen is found, this time of the Pink fairies (Caladenia latifolia) which is found between Kalbarri and Israelite Bay from August to early-December.

Upon crossing the road, the first orchid found appears to be a hybrid. The parentage was hard to decipher until we found one of the parents close by.
I have decided the parents are Caladenia attingens x barbarossa.
Posted on iNaturalist for thoughts from others.

Just past the hybrid orchid we come across one of the parents. The Common dragon orchid (Caladenia barbarossa) is found scattered at the top of the ridge above the river flat.
These orchids are found between Bindoon and Esperance from September to mid-November.

Another orchid found as two separate specimens was the Beautiful donkey orchid (Diuris pulchella) which is listed as growing between Salmon Gums and Israelite Bay from July to September. The specimens were north and south of the river.
Our location is some 50km southwest of Salmon Gums but the species is recorded at this location in the Atlas of Living Australia.

As I was taking photos of orchids found Debbie is exploring further afield and she yells out excitedly.
She has come across a vast warren of the Rabbit orchid (Leptoceras menziesii) which has flowered due to the previous summer bushfire that scorched this area.
These orchids are found growing between Northampton and Israelite Bay from September to early-November.

Close by we also found the Esperance white spider orchid (Caladenia longicauda subsp. crassa) which occurs between Bremer and Israelite Bays from August to early-October.
Some may be the related Rigid white spider orchid (Caladenia longicauda subsp. rigidula) which occurs between Ravensthorpe and Israelite Bay during a similar flowering season.
The differences between the 2 species are the size of the flower and the rigidness or pendulousness of the petals and sepals.
Let me know your thoughts.

Crossing back over the river we come across more spider orchids that appear to be further Esperance king spider orchids.
However the better find was some other species of Donkey orchid. Due to the location and date found, I will be naming these the Green Range donkey orchid (Diuris littoralis) which is recorded as occurring between Denmark and Esperance from July to early-September.

Finally made it back to Fili at around 2pm and move onto another location.
16 species found at this location.
Part III to follow… Stay tuned

Top Orchids Found West of Esperance: A Field Report; Part I

Day Trip, Lake Mortijinup NR, Nature Reserves, Western Australian Orchids

04/09/2024

Today Deb and I decide to head out west of Esperance to see what we can find.
Our first destination is Lake Monjinup which is located in the Lake Mortijinup Nature Reserve which is also referred to as Lake Monjingup Reserve. 3 different spellings and differing details on the size of the reserve make things rather confusing.
This is only a quick check around the parking area as we have many kms to go today.

As would be expected the first orchids found were the Esperance king spider orchids (Caladenia decora). They are amazing large spider orchids that can be so dazzling in their colours.

Another dazzling orchid is found. These are the much smaller Pink fairies (Caladenia latifolia) which as the name suggests are pink in colour.
They do have a much larger range, occurring between Kalbarri and Israelite Bay in WA but are also found in Vic, Tas, and SA. The Esperance king spider by comparison is found only between Bremer Bay and Cape Arid in WA.

Our next stop is nearly 1 hours’ drive west in Coomalbidgup⁹. We park up off the road and venture into the roadside vegetation. This was just one of those “Let’s check this spot out” random choices.
And guess what? It paid off this time 🙂

First up we find the Purple enamel orchid (Elythranthera brunonis) growing sporadically over the location searched. These orchids are found between Kalbarri and Israelite Bay.

Another orchid found throughout this location was the bright yellow Common bee orchid (Diuris decrementum). These small orchids are found from near to Perth to east of Esperance.

A 2nd species of yellow orchid is also found. The common Cowslip orchid (Caladenia flava subsp. flava) was expected but is always a surprise to find as well. This particular subspecies is the most widespread of the 4 names subspecies.

Who would have picked it, another yellow orchid is found in good numbers. The Twisted sun orchid (Thelymitra flexuosa) grows with sedges and low shrubs in moist places such as the edge of swamps.
It is found between Kalbarri and Israelite Bay and is also found in southern Vic, south-eastern SA and Tas.

Also found at this location were more Esperance king spider orchids.

The discovery of the final orchid at this location was unexpected, as the area has not seen a recent burn. Red beaks (Pyrorchis nigricans) typically flower following a summer fire however, rare specimens bloom without fire, which appears to be case in instance.
Found between Shark Bay and Israelite Bay in WA and all Australian states except Qld and the NT.

Next stop is a new Coomalbidgup¹⁰ spot where the powerline gives easy access.
Today, we encountered additional specimens of some previously identified orchids so I will post a picture of them to document their presence at this new location.

New species for the day were also found. Firstly, came the Esperance white spider orchid (Caladenia longicauda subsp. crassa) which as the name suggests is found in a range between Bremer Bay and Cape Arid which includes Esperance.

A solitary Western tiny blue orchid (Cyanicula aperta) was found. These small guys flower between Ongerup and Israelite Bay.
Pics taken from different angles either highlight or diminish the blue colouring of the orchid flower.

And the final new species found at this new location was the bright Lemon-scented sun orchid (Thelymitra antennifera) which is found flowering between Shark and Israelite Bays.

We head further north up Neds Corner Road and make a random roadside stop at some low granite. On the West side of the road, it was covered in water but on the East side it was mainly dry.
We found orchids on both sides of the road, though mostly the same as previously found today.
Common bee orchids, Lemon-scented sun orchids and Cowslip orchids listed for recording purposes.

New species for today is found on the East side of the road.
The Small mantis orchid (Caladenia attingens subsp. gracillima) is found flowering between Jerramungup and Israelite Bay.

A spent Jug orchid (Pterosylis recurva) was found as were some orchids yet to flower.
Thelymitra, Microtis and possibly Prasophyllum orchids in bud and some leaves to tempt us.
We move on but not too far of course 🙂

Only a little way up the road will pull over at another random spot due to a change in vegetation cover.
First up hiding underneath a shrub a compact clump of Western tiny blue orchids is found.

An exciting find here was a small patch of the Dwarf shell orchid (Pterostylis brevichila). These orchids are found flowering between Hyden and Mount Arid.

Another new orchid for today is found, from the Caladenia genus, which is always exciting. The Short-sepaled spider orchid (Caladenia brevisura) is another easterly located orchid, as it grows between Ravensthorpe and Israelite Bay.

The next orchids found are the small Zebra orchid (Caladenia cairnsiana) and the Frog greenhood (Pterostylis sargentii) which are found from Watheroo to Esperance and Mullewa to Grass Patch respectively.

Then some further Esperance white spider orchids and Small mantis orchids are found. As usual I will post a pic of each for recording purposes.

As we proceed, we take a moment to reflect on the discovery of 15 distinct species of orchids. With additional locations yet to be explored, this promises to be a highly successful orchid hunting expedition.
As I compose these blog posts several months after the actual date, I am dividing this day into three reports. Stay tuned for Part II and III.

Orchid Hunting Adventure East of Esperance: 28 Unique Species

Mount Burdett NR, Mount Ridley NR, Western Australian Orchids

26/08/2024

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.

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.

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.

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.

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.

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

Intermixed with the dwarf zebra orchids were some small spider orchids.
They appear to be more Cream spider orchids.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 !!

Cream spider orchids blowing in the wind

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.

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.

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

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.

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.

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.

Further afield I stumble across the Esperance white spider orchid (Caladenia longicauda subsp. crassa) growing within the scrub.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

Orchid diversity in Coomalbidgup and East Munglingup

Western Australian Orchids

21/08/2024

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.

Exploring Orchid Diversity north of Esperance

Helms Arboretum, Nature Reserves, Swan Lagoon NR, Western Australian Orchids

17/08/2024

So today we decide to head north of Esperance to see what the season has produced. We don’t get far before we pull into our first stop of the day.
Helms Arboretum is always a favourite stop.

Starting off small the first orchid found was the Zebra orchid (Caladenia cairnsiana).

These orchids are found growing between Lancelin and Esperance. They have only recently started flowering as their season commences in August and extends to early-November.

They are recorded as growing to heights of 400mm which would be amazing to find. Our specimens are more around the 200mm range.

Next our targeted orchid the Grass-leafed spider orchid (Caladenia graminifolia) was found.

These orchids also commence their flowering in August, then until September only.

They range from Mt Manypeaks to Israelite Bay so appears restricted to the south coast.

The Esperance king spider orchid (Caladenia decora) was represented by a single specimen found nearby the aforementioned orchids.

This king spider orchid is located from Bremer Bay to Cape Arid. Its season is mid-August to October.

We don’t stay longer at Helms as we only popped in here to find a flowering Grass-leafed spider orchid.

Our next stop is near Gibson¹⁴. We walk along the tracks and every so often we venture into the surrounding scrub.

A solitary Blue beard (Pheladenia deformis) is found first.

These orchids flower from late-May to October.

In WA they occur between Murchison River to Israelite Bay.

As this area has been burnt in the last few years, we were still able to find some Redbeaks (Pyrorchis nigricans) in flower.

Redbeaks flower from August to October.

They are found from Shark Bay to Israelite Bay, which is one of the largest ranges for an orchid in WA.

Throughout the area checked we came across a few patches of the Cowslip orchid (Caladenia flava subsp. flava).

This subspecies is the most widespread and ranges between Northampton and Israelite Bay.
It also has the longest flowering season; July to early-December.

There are 4 subspecies of the Cowslip orchid. The other 3 are restricted to much smaller ranges that all overlap the range of the subspecies found around Esperance.

We did make an exciting find of a hammer orchid leaf in bud.
From the leaf I believe it will be the King-In-His-Carriage orchid (Drakaea glyptodon).

These orchids flower August to October over a range between Eneabba and Esperance.

However, the most prolific orchid found at this location was the Esperance king spider orchid.

It was found either as a lonely specimen or in good size groups.

If any of the flowers pictured are the similar C. heberleana, please comment on this post.

We move further north up the highway to another location in the Gibson area ¹⁵.
A gate had been installed which precluded us for heading down the track. We instead checked out the verge and walked a bit into the scrub.

Hiding under the verge scrub we find the Jug orchid (Pterostylis recurva).

This unusual but common orchid is found between Geraldton and Israelite Bay.

Flowering season is only from August to October

Deb has her eye in for spying orchids as she stumbles across an exciting find for this location.

The first orchid found is so small. Refer pic with the tip of my index finger for size comparison.

The Reaching spider orchid (Caladenia arrecta) is so named due to its erect petals.

Found between Bindoon and Israelite Bay.

Flowering season from late-July to mid-October.

We now move onto a new location, further north. We turn left at Hawkey Road them immediately right into Swan Lagoon Road. Our first stop ¹⁶ along this road is down a track in some bushland.
We take this slowly and regularly get out to walk along and into the surrounding scrub. It is along this track that we pull over and have lunch from the back of the Triton.

The orchid that stands out for this location is the Western Tiny Blue orchid (Cyanicula aperta). It was found in huge numbers.

They are found flowering from August to early-October between Dumbleyung and Mt Ragged.

They have horizontally held petals and lateral sepals and can grow up to 150mm in height.

Another very similar orchid is also found, however not is such great numbers.

The Sugar orchid (Ericksonella saccharata) flowers in August and September between Paynes Find and Israelite Bay.

A small number of Midget greenhoods (Pterostylis mutica) were found along the way.

These orchids flower from July to October between Wongan Hills and the SA border.

They can grow to 200mm in height and can have up to 15 small green flowers.

A further Pterostylis orchid is found in small numbers.

The Brittle snail orchid (Pterostylis timothyi) flowers July to September between Lake Cronin and Esperance.

Some distinctive features are having a small rosette of pointed prominently veined leaves and only one or two stem leaves.

The we find one of the newest named Greenhoods. The Mallee banded greenhood (Pterostylis arbuscula) was formally named in 2018.

The flower between Dalwallinu and Eyre bird observatory during the months June and July.

As we are now in August this could explain why we only found two still in flower.

Amazingly we find a Grass-leafed spider orchid in this new location. So that makes a third spot we have found this orchid. Helms and Stokes NP are the other locations.

Another orchid of the Pterostylis genus is found. Only one specimen found, so was very lucky to have spotted it.

This time it is the Dwarf shell orchid (Pterostylis brevichila) which flowers from July to September.

It has an inland southeastern range, occurring from Hyden to Mt Ragged.

The Jug orchid is found at numerous spots in this location.

Pictures taken for registration purposes.

Just before we decide to have a break for lunch, we finally find a donkey orchid.

There are 2 possible ID’s for these orchids. They could be the South Coast donkey orchid (Diuris brockmanii) or the Yellow granite donkey orchid (Diuris hazeliae).

Flowering is June to early August and Aug to September respectively.
So, the ones that already have finished flowers could very well be the former.

As both are recorded for the Grass Patch area any assistance in positive ID would be appreciated.

Note the brightness of the yellow is greatest with the mobile phone pics.

Whilst eating lunch we still explore nearby.
It is here we find some different orchids than found previously today.

Due to the location, they must be the Small mantis orchid (Caladenia attingens subsp. gracillima).

These orchids flower from August to early-October between Jerramungup and Israelite Bay.

The flowers are green, yellow and red in colour and can grow up to 350mm in height.

The prominently upcurved lateral sepals are distinctive to most mantis orchids.

Back on Swan Lagoon Road we travel further north and pull into another track which is much shorter, so we walk it. ¹⁷

Blown away by the numbers of Western tiny blue orchids found.

I have posted a video below to show how many occur in say 1 square metre.

So many Western tiny blue orchids

Another previously found orchid is also found in greater numbers.

The Midget greenhood rears it lime green coloured head again.

Also found was another Mallee banded greenhood.

Moving further north again we make a final stop in the Swan Lagoon Nature Reserve.
Initially we turn up nothing in the lagoon area however further afield our luck changes.

Seems a regular occurrence today. Blue beards are also found in greater numbers than earlier today.

Well, we finally start finding the small spider orchids in flower. Actually, we find loads of them, and they may possibly be 2 species.

One is definitely the Western wispy spider orchid (Caladenia microchila).

This orchid is a common southeastern inland species. It is found between Kondinin and Madura.

Flowers occur July through to early-October.

If another species is apparent from the pictures supplied, can you please enlighten me. I am swaying to C. dimidia or C. horistes

Intermixed with the wispy style spider orchids we also find the Short sepaled spider orchid (Caladenia brevisura) standing proud.

These orchids flower between Jerramungup and Israelite Bay during August and September.

The common name refers to the shortened sepal tips, when compared to the similar C. doutchiae.

Larger spider orchids appear as we progress with our exploration of this Nature Reserve.

Due to the shorter length of the petals and sepals, plus the dull white colouring I believe they are the Reclining spider orchid (Caladenia cruscula).

These orchids are found between Salmon Gums and Mt Ragged / Israelite Bay.

Flowering during August and September.

More donkey orchids are found near the large spider orchids.

Positive ID again not attempted. Could be D. hazeliae or D. brockmanii. Thoughts??

Midget and Mallee greenhood orchids were also found at this location. Pics for recording purposes.

Our final orchid of the day was the small Sigmoid spider orchid (Caladenia sigmoidea) which was very exciting.

The name “Sigmoid” refers to the ‘S’ shaped labellum tip.

These orchids grow between Mt Jackson and Mt Ragged.

Flowering during the months of July, August and September.

They are very small, ranging from 50 to 150mm in height. Their colouring blends into their surroundings. This makes finding them difficult.

We were blown away by the numbers found. Previously, we have only found them solo or as spread-out isolated specimens.

Well, this hunt was a great success. So many orchids found, with some in huge numbers.
The highlights were the patches of Western tiny blue orchids and the large number of Sigmoid spider orchids found.

At least 20 species found!!

15/09/2023 ….. Final day of 2023 Road Trip :(

Beaumont NR, Clyde Hill NR, Condingup Water Reserve, Nature Reserves, Numerous days, Other Reserves, Road Trip

After a restful night at the Deralinya Homestead campground, we enjoy a peaceful breakfast. We then quickly pack up camp and head off on the track to Mount Coobaninya. But, after less than 2kms we turn back due to many trees fallen on the track. It seems the strong winds we encountered on the Nullarbor hit here with impact.

Back at the Homestead we pull up at the granite rock that forms the catchment for the dam and go for an orchid exploration. Sun orchids are found with some actually open so we can record their finding. They appear to be the Granite sun orchid (Thelymitra petrophila) which is found flowering from August to November. They occur from Mullewa out to Israelite Bay which is southeast of here.

So many Sun orchids found both flowering and still in bud. The other orchid found was the Little laughing leek orchid (Prasophyllum gracile) which are found between Shark Bay and the Great Australian Bight. These ones are not as far gone as the ones found yesterday.

We have a quick look at the homestead as the occupants had left for the morning. It was very interesting to see.
The Heritage Council of WA has this recorded on it’s website : The well constructed buildings of local materials were built by a well known character of the area. George Burns Scott was a pioneer with a dam sinking plant who liked building and establishing stations and then moving on. The painter, A E Baesjou. lived there for some years as a little girl. The property was used as an outstation to Balladonia until 1936 when the roofs were removed. The last load of wool was taken out in 1920. Cattle were run there until 1936.

Moving further south we next stop at Breeboorinia Rock. The occupants from Deralinya Homestead cleared the track into here of fallen trees this same morning. This was opportune for us.
Upon exploring the rock, we first come across the Granite sun orchid. Only 2 good specimens found with pics taken for recording purposes.

The Desert mignonette orchid (Microtis eremicola) was also found growing on the granite. As these orchids flower during September and October only a couple of newly flowering orchids were located. As the common name suggests, these orchids are found in a drier part of the state. Their recorded range is between Hyden and Balladonia.

Then in a bushy patch Deb comes across what appears to be very pale Cowslips. Upon closer inspection, I believe them to be the hybrid known as Dusky fairy orchid (Caladenia x erminea). This is due to the yellow/white colouring. It is also because of the hairs on the underside of the sepals. They are listed as occurring between Esperance and Perth during September through November.

One of the parents to the hybrid was also found in the thick scrub of the granite depression. The Cowslip orchid (Caladenia flava subsp. flava) was growing in an isolated group. They were very bright yellow in colour, in comparison to the hybrids.

We quickly check out the dam at the base of the rock. It is covered in wattle pollen, giving it a yellow tinge.

We make our way back to the Triton. On our way out we noticed the colour yellow in the surrounding grasses. Upon closer inspection, it is the Lemon-scented sun orchid (Thelymitra antennifera). This orchid is found flowering from Shark Bay to Israelite Bay during the months July through October.

We now head off and come to the beginning of the farms. In the middle of the farms is Clyde Hill Nature Reserve. Here we pull up and go for an exploration as this is our first visit to this reserve. Well, this proves to be a great location for orchids at this time of the season. Whilst walking along the track into the granite hill, we first come across a solitary Midget greenhood (Pterostylis mutica). A cobweb holds it prisoner.

Then another new orchid for the day is found. Pics of the various ones found in this location will be shown together to reduce the size of this post. The Short-sepaled spider orchid (Caladenia brevisura) flowers in August and September from Jerramungup to Israelite Bay.

Next up we find both the Lemon-scented sun orchid and Granite Sun orchid flowering. These 2 orchids are recorded as being the parents to an Un-named hybrid orchid ( Thelymitra antennifera x petrophila). Amazingly we find one of these in flower as well. I will post pics of all 3 orchids.

Another new orchid for the day is found. The Granite mantis orchid (Caladenia attingens subsp. effusa) flowers from August to early October between Peak Charles and Balladonia. The distinctive feature is the slightly upcurved lateral sepals. The related and possibly co-occurring Small mantis orchid has prominently upcurved lateral sepals.

Of course, we also come across the ever-faithful Cowslip orchid. These are found in most locations where orchids flower between Northampton and Israelite Bay. They can be found as early as July right through to December.

Next up is another new orchid for the day. The Pink fairies (Caladenia latifolia) are found from August to December between Kalbarri to Israelite Bay. The bright pink colour stood out from the surrounding greens and browns.

Well, we must keep moving so back to the Triton we go and southwards along Parmango road we head. Along the roadside we come to a spot that appears to have had a summer burn go through. We stop for an exploration.
Glad we did as we did as we soon come across the Purple enamel orchid (Elythranthera brunonis). Actually, we end up finding loads in this spot which was amazing. These unique orchids flower from August to November, between Kalbarri and Israelite Bay.

As we had expected we came across Red Beaks (Pyrorchis nigricans) flowering. These orchids usually only flower after a summer fire the season before. But it is possible to find the odd one flowering without a fire.

Also discovered the large Esperance king spider orchid (Caladenia decora) which flowers from mid-August to October between Bremer Bay and Cape Arid.

Another similar coloured orchid is also found. The Dancing spider orchid (Caladenia discoidea) flowers August to early-October between Kalbarri and Israelite Bay.

An inconspicuous orchid is found in the early stages of development. The Common mignonette orchid (Microtis media subsp. media) is found flowering from September to January between Shark Bay and Eyre.

A surprising find was a solitary Common spider orchid (Caladenia varians) in flower. These orchids are found flowering from July to mid-October between Kalbarri and Esperance.

But the best find so far is the Custard orchid (Thelymitra villosa). This was not an expected find at all, so we were shocked in a good way. These orchids are found between Northampton and Esperance flowering over spring.

Two other orchids already found today were also found at this location. Cowslip orchid and Lemon-scented sun orchid just added to the yellow of the Custard orchid. Time to move on to the next location.

We arrive at Beaumont Nature Reserve, park up and head off exploring. Orchids that were recorded earlier today are also found at this location. They are captured in pictures below as a record of where they are found.

Purple enamel orchid (Elythranthera brunonis)

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.

Esperance white spider orchid (Caladenia longicauda subsp. crassa)

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.

25/09/2022 ….. Gibbo re-visited.

List of Orchids Found, Sunday Drive, Western Australian Orchids

Earlier this season (June) we checked out the burnt area north of Gibson and found greenhoods but nothing else.
