Orchid Adventures on the Road to Perth

Pallarup NR, Road Trip, Western Australian Orchids

28/08/2024

Heading up to Perth for a few days so made sure to stop along the way to look for some orchids in flower.
First stop after 2 or so hours of driving is at the rock in Pallarup Nature Reserve.
Only had a quick 15 min walk around and found 3 species.

Pink Candy orchid
(Caladenia hirta subsp. rosea)

Sugar orchid
(Ericksonella saccharata)

Frog greenhood
(Pterostylis sargentii)

There are 2 species of Frog greenhoods, but I did not obtain a closeup pic of the labellum, which is a distinguishing feature, so have listed the original name for now.

Next stop was at the Lake Grace Lookout for a lunch break and of course an orchid hunt.

Jug orchid / recurved shell orchid / Antelope orchid / Bull orchid
(Pterostylis recurva)

This orchid has many Common Names

Sugar orchid
(Ericksonella saccharata)

Western wheatbelt donkey orchid
(Diuris brachyscapa)

Chameleon spider orchid
(Caladenia dimidia)

I have posted 4 pics as I wanted to show the varied colours of this orchid.

Well, no more stops as it is an 8hr or so drive to Perth and I wish to arrive before the kangaroos come out at dusk.

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

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!!

06/08/2023 ….. Discovering a Diverse Array of Orchids in East Esperance: A Photographic Journey

Condingup Water Reserve, Other Reserves, Sunday Drive, Western Australian Orchids

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.

29/07/2023 ….. A week spent wandering – Part 8

Nature Reserves, Pallinup NR, Western Australian Orchids

All to soon our week away comes to an end. We leave Albany and head northeast along National Highway No. 1 to Wellstead where we make a quick stop at the TransWA bus bay. No orchids found flowering however we did find some Redbeak leaves and the beautiful Silver princess (Eucalyptus caesia) in flower. From here we continue along until we reach a pull over spot in the Pallinup Nature Reserve.

Driving into the parking bay we spy some donkey orchids in flower. A promising start however it did prove to be not so. The Green Range donkey orchid (Diuris littoralis) is the likely species of donkey orchid as they flower from July to early September over a range from Denmark to Esperance in a coastal and near coastal locations. Other than these in flower there are a couple of Banded greenhoods (Pterostylis vittata) in flower and some Jug orchids (Pterostylis recurva) close to flowering. Nothing else found, which is disappointing.

Moving on we head toward Jerramungup, where we plan to check out the recently burnt area again to see what is now in flower. First up though we check out a location shared to us by a friend who used to live in the area. Down Carlawillup Road we go, until we reach the gully. Here we pull over and have a quick scout around. Only Banded greenhoods and other nearly in flower jug orchids were found. Will need to check this location out further into the orchid season to see what is flowering then.

Back to the burnt area near Jerry and again we are a bit disappointed as we find loads of donkey orchids and a few Banded greenhoods. The only other interesting find were some Redbeaks from last season with their charcoal black dried flowers. The Latin “pyr” (fire), “orchis” (pertaining to Orchidaceae) & “niger” (black) show how this scientific name Pyrorchis nigricans was chosen. They flower after fire and the dried flower is black in colour.
The other issue is naming the donkey orchids as they do appear to differ in their appearance. So some may be the Green Range donkey orchid as noted being found earlier today, whilst others could be the South Coast donkey orchid (Diuris brockmanii). The latter orchid flowers between Ongerup and Esperance from June to early August, so they could co-occur.

We now make tracks for Newdegate, where we plan to stay in the local hotel for the night. A rustic hotel which was busy with the locals, so our wonderful meal was eaten in the company of many. Only one more day of travel before we reach home, so we try and get a good night’s sleep, however the heater kept cutting out so needed to be reset many times.

28/07/2024 ….. A week spent wandering – Part 7

Gull Rock NP, Mount Martin Botanical Reserve, National Parks, Numerous days, Other Reserves, Road Trip, Western Australian Orchids

Today we go on our planned quest to find the elusive Queen of Sheba orchid which has been recorded from Gull Rock National Park by many people in the Western Australian Native Orchids Facebook group. We may be too early however as the one around Albany is recorded as flowering from August, so fingers crossed.
First off, we head down Ledge Beach Rd and check out the beach. From here we walk around the parking area, and it is here we find our first orchids for the day.
Just for a change, NOT, our first orchid found is the Banded greenhood (Pterostylis vittata).

Then some other Pterostylis orchids are found. These small snail orchids could be the Coastal short-eared snail orchid (Pterostylis actites) given the short backswept lateral sepals. They are recorded as occurring from Capel to Duke of Orleans Bay and flower from July to September. The rosette has 4 to 7 leaves, and they stand up to 100mm in height.

Another exciting find here was a further patch of the Common helmet orchid (Corysanthes recurva) hiding under an overhanging shrub. Harder to get a clear shot but tried my best. These orchids are found between Mandurah and Albany and flower from June to September.

We now decide to head off on the Mount Martin walk trail which starts from the Ledge beach carpark which is in the National Park however the majority of the walk trail is in the Mount Martin Botanical Reserve. We do not do the entire trail, so I have attached a snip showing approximately where we walked. Arrows show direction and X marks turnaround spots. First orchids found on the walk were further Banded greenhoods together with Slipper orchid leaves and a Redbeak leaf.

Then we nearly step on those things we have come to find. We find very small spiral leaved orchids in bud. A few patches found however none were in flower. Oh well they may be the Queens or possibly just some Curly Locks. We now know to come early August for a better chance of finding them in bloom. Pics taken as proof of the find.

Orchids may be few and far between however the coastal views and other wildflowers make up for it.

We are heading down toward Coal Basket Bay when at a patch of granite, we find some Autumn Leek orchids (Prasophyllum parvifolium) in flower. These orchids flower over the winter months, so the common name seems a bit off.

It is here we turn around as the track is getting rather steep and as orchids are so rare we decide we need to get back to check out other areas of the National Park. At another granite location possibly called Mount Eileen Lookout we find more Banded greenhoods and a nice patch of spent Mosquito orchids.

At the next little patch of granite crossed we are excited to find the Pink bunny orchid (Eriochilus scaber subsp. scaber) flowering. These small orchids are found during the months of July to September and are usually found the season after a summer bushfire. Without a summer fire they are flowering much more rarely.

Upon arriving back at the carpark, we make tracks for Ledge Point Road and checked out Gull Rock Beach carpark. Seemed more peppermint trees around with no picnic table so we again had a tailgate lunch. A quick check whilst eating turned up some snail orchids. These ones however have long thin lateral sepals so are a different species to those found earlier today. Possible ID – Brittle snail orchid (Pterostylis timothyi) or Slender snail orchid (Pterostylis crispula). Both have long lateral sepals, flared petals and flower from July. P.timothyi though is not recorded as being found in the Albany shire, however it is the shorter of the two and has fewer cauline leaves, so I am confused. Any help in the ID would be appreciated.

Now to check out some other spots in the National Park. We pull over at a gate off of Gull Rock Road and go for a hike up the track. The track goes through some differing habitats but unfortunately, we only find a few Banded greenhoods flowering.

Further along the road we get excited to actually find a common orchid but one we had not seen so far today. The Jug orchid (Pterostylis recurva) is recorded as flowering from August, so we were lucky to find an early twin. Another single specimen was found together with another beautiful Scarlet banksia surrounded by blue flowers.

It was at this sole Jug orchid where we took a very overgrown track into the bush as it provided a much easier pathway off the road. We arrived at a sort of clearing with quite large boulders and pushed up mounds of dirt. It is around this disturbance that we find a few Autumn leek orchids in flower.

Well, that is the last of our orchid finds for today! Back in Albany we have the hard task of where to go for dinner. We decide to try out Little Italy in York Street and enjoy some beautiful pasta.

24/07/2023 ….. A week spent wandering – Part 3

Lane Pool Reserve, Numerous days, Other Reserves, Road Trip, Western Australian Orchids

After breakfast with Richard at his house sit on Rockingham beach we make tracks for Dwellingup via lunch in Mandurah with sister Maxine. We detour along Scarp road for a quick explore as we will catch up with brother Geoff after he finishes work. We touch the boundary of Lane Pool Reserve, so unsure if our locations are in the reserve or not but will record them as so.

Orchids are found which is exciting. First up is the Banded greenhood (Pterostylis vittata) which is a green and white striped orchid which is found between Perth and Israelite Bay. They range in height from 100 to 450mm and can have between 1 and 25 flowers per plant. In fact, one of the orchids found measured over 530mm in height. Pic with tape measure taken as proof.

Also discovered were some Slender snail orchids (Pterostylis crispula) which are found between Perth and Albany growing in sandy, sandy-clay and lateritic soils in forests, woodlands and shrublands. They flower from July through to early October and can grow to 250mm in height. The petals and dorsal sepal are joined and form a hood with the dorsal sepal forming a short point.

The Jug orchid (Pterostylis recurva) was also found; however, it was not fully open as yet, which fits with the recorded flowering period being August to October. We then continued on to Dwellingup, however Geoff was still at work so whilst Deb had a relax, I went for a quick walk into the surrounding bush and came across the rosettes of some Bird orchids (Pterostylis sp.) which are also listed as flowering from July/August so just a tad early it seems. Pics taken of both for recording purposes.

Geoff arrives home and takes us for a drive out to the river to show us the Dwaarlindjirraap Bridge over the river constructed for bicycles and pedestrians only. It was an amazing site and a great way to end the day before having a wonderful night at Geoff and Robyn’s place.

07/10/2022 ….. Pootenup Nature Reserve

Nature Reserves, Numerous days, Pootenup NR, Road Trip, Western Australian Orchids

Meeting up with Debbie in Cranbrook this morning. I drove down from Katanning, and she drove up from King River. So, the plan is to take a winding route back to Esperance over the next the next 3 days, with regular stops to search for orchids. After grabbing a cuppa from the Cranbrook store, we head up the Great Southern Highway, but only get as far as Pootenup Nature Reserve, where we pull over for our first exploration. This is a new location, so we are hopeful of finding some orchids.

First up some large Green spider orchids (Caladenia falcata), also called the Fringed mantis orchid, are found with many twins flowering. They can have up to 3 flowers per orchid, so twins are nice to find. They are a common orchid, flowering between Wongan Hills and Jerramungup, from late August to October.

We thought we found a lot of Green spider orchids, but the number of White spider orchids was unbelievable. From the location I feel the large white spider orchids to be the Stark white spider orchid (Caladenia longicauda subsp. eminens), which flowers between Moora and Esperance, during August to early October.

However, some of the white spider orchids are smaller with thinner labellum and shorter fringe segments. After checking the references these ones may be the Tangled white spider orchid (Caladenia longicauda subsp. redacta) which occurs between Collie, Mount Barker and York, growing in sandy-clay soils and seasonally moist flats in forests and woodlands. I will post some pics for you to decide if I am correct in the identification. If not, please let me know.

Other orchids are also found interspersed between all the large green and white spider orchids. A lone Jug orchid (Pterostylis recurva) with 5 flowers in various stages of bloom is one of these. From the reference books having five flowers is somewhat rare, so this is an exciting find, for such a common orchid. Another common orchid found, though not too common at this location, is the Common bee orchid (Diuris decrementum), which is often found growing in clumps and occurs from north of Perth to east of Esperance.

Another common yellow coloured orchid is found but again not common in this location. The Cowslip orchid (Caladenia flava subsp. flava) differs wildly in its markings, as shown by the two specimens found. One has red lines and dots whilst the other is mostly dots. Where the various subspecies overlap these variations cause confusion in making a positive ID.

A hybrid orchid is found which should not have come as a surprise as the probable parents are both found in large numbers. That said, finding a hybrid is always exciting. The named hybrid, Wheatbelt spider orchid (Caladenia x cala) is a cross between the Green spider orchid (C. falcata) and a white spider orchid (C. longicauda).

Another surprise is finding the Pink enamel orchid (Elythranthera emarginata) which is found between Jurien Bay and Ravensthorpe, from October to December. This is a beautiful, bright orchid that grows in sandy, sandy-clay and clay soils in forests, woodlands and shrublands.

Hiding behind the spectacular foursome of Pink enamel orchids you can see some small white orchids. These little beauties are the White fairy orchid (Caladenia marginata), which are found between Jurien and Israelite Bays over the spring months.

Now for the difficult part, trying to ID the smaller spider orchids. The location leads me to believe that the majority of them are the Joseph’s spider orchid (Caladenia polychroma), which is a variably coloured orchid found growing between Boyup Brook and Fitzgerald River National Park during the months of September and October. Listed as growing in woodlands with grassy to herb-rich ground cover, on seasonally damp clay-loam soils.

However, some of the red spider orchids could be the Crimson spider orchid (Caladenia footeana) which is listed as growing between Cranbrook and Binnu, from July through to October. EDIT: Identification via iNaturalist confirms correct ID is the Joseph’s Spider orchid (C. polychroma)

I struggle with identifying some orchids so I will post the pictures with the expectation that someone will advise me what species they believe them to be. Thank you in advance.
