Discovering Orchids: A Southeast WA Pub Crawl Adventure

List of Orchids Found, Numerous days, Pallarup NR, Road Trip, Western Australian Orchids

07/09/2024

Today is the day that our Pub Crawl around the Southeast of WA commences.
We head off in the Triton around 8.45 am and venture over to Nulsen to pick up our travelling companions for the adventure, Bob and Jan.
First stop is at the Munglinup¹ Roadhouse, where I take the time to have a very quick check for orchids.

8 species are found, which is quite unbelievable.
First up, the reliable Cowslip orchid (Caladenia flava subsp. flava) is found.
Next is a large white spider orchid, which, given its location, I will name the Esperance white spider orchid (Caladenia longicauda subsp. crassa).
Thirdly is one of the smaller spider orchids from the Filamentosa complex. It is most likely the Common spider orchid (Caladenia varians).
Next is the small Zebra orchid (Caladenia cairnsiana).
The 5th orchid found is the Lemon-scented sun orchid (Thelymitra antennifera).
A not fully opened Purple enamel orchid (Elythranthera brunonis) is found next.
The 7th orchid for the day is the Dancing spider orchid (Caladenia discoidea).
Final and 8th orchid for this location is the Small mantis orchid (Caladenia attingens subsp. gracillima).

We now move on to the lookout on Ethel Daw Drive in the Ravensthorpe shire. Only 2 species were found along the roadside.
First up is the Western tiny blue orchid (Cyanicula aperta), followed by the Sugar orchid (Ericksonella saccharata).

Moving back to Elverdton Road, we head west and pull into a new location I will name Ravensthorpe¹.
Walking along this dirt track, we locate 4 species, 1 new for the day.
Found again were the Small mantis orchid, Sugar orchid and Western tiny blue orchid.
The new species for the day is the Common dragon orchid (Caladenia barbarossa).
Terrible pictures were taken, so I will include only 2.

***Caladenia attingens subsp. gracillima***

Passing through Ravensthorpe, will pull into Kukernup Memorial to have lunch.
After having a bite to eat, we all venture out to explore the walk trail.
It was a great spot, as we found 9 orchid species in flower.
First up is the Jug orchid (Pterostylis recurva),
Next, more Dancing spider orchids and Common dragon orchids are found.
Also found again were more Small mantis orchids, Lemon-scented sun orchids, Cowslip orchids and Purple enamel orchids.
Other new species found for the day are the Redbeak (Pyrorchis nigricans) and the Frog greenhood (Pterostylis sargentii).

We now backtrack to the road leading to Lake King and head north. Next stop is one of our all-time favourite places.
Pallarup Rocks picnic area provides loads of places to explore for orchids.
We are not disappointed with the species located.
First up are the Sugar orchid, Cowslip orchid, Jug orchid, Purple enamel orchid, and Lemon-scented sun orchid, which were all found earlier today at prior locations.

New species found start with the Ant orchid (Caladenia roei), quickly followed by the closely related Short-sepaled spider orchid (Caladenia brevisura) and Purple-veined spider orchid (Caladenia doutchiae).

The next new species found for the day was the Pink candy orchid(Caladenia hirta subsp. rosea) together with its hybrid – Tinged spider orchid(Caladenia x suffusa).
So, now to find the other possible parent of the hybrid. Due to the location, I believe the other parent to be the Pallarup white spider orchid (Caladenia longicauda subsp. ‘Pallarup’). Luckily specimens are found.

Once up on the granite rock we come across some donkey orchids. I believe them to be the Yellow granite donkey orchid (Diuris hazeliae). I have posted images of 3 orchids as they may represent another species.

A smaller whiteish spider orchid is found in various shades, however I feel they are all the Chameleon spider orchid (Caladenia dimidia).

Do you agree they are all one species?

Also found a nice bunch of what appears to be another orchid species, possibly the Central wheatbelt spider orchid (Caladenia sp. ‘central wheatbelt’) however is outside of the recorded location.

Thoughts?

Another frog greenhood is found however on closer inspection; it is actually a Little frog greenhood (Pterostylis occulta) due to the hairy narrow horn-like labellum structures.
2 pics posted to show this aspect as clearly as possible

Another new orchid for the day is the Little laughing leek orchid (Prasophyllum gracile) which is found growing in shallow soil on the granite.

Other random hybrids are found during the search, and I will post them below for record keeping. Assigning parents is always difficult for hybrids especially between the Roei and Filamentosa complexes.

Well that is our final orchid stop for the day, so it is off to our first hotel stay. Night 1 is spent at the Newdegate Hotel.
Checked out the Silo Art before settling in for the night.

23 species found with a possible 4 hybrids, plus a possible new species but outside its usual range.

Amazing first day !!!!

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

Day Trip, Western Australian Orchids

So we move onto our 7th location of the day which is just another random roadside stop on the boundary between Coomalbidgup and East Munglinup localities. All depends on which side of the road you are 🙂

The Western tiny blue orchid (Cyanicula aperta) is the first orchid found at this spot. These little orchids are found between Dumbleyung and Mt Ragged from August to early-October.

Next up the Purple enamel orchid (Elythranthera brunonis) is spotted dotted around this location. They can be found growing between Israelite Bay and Kalbarri from August to early-November,

An orchid that is found on both sides of the road is the Small mantis orchid (Caladenia attingens subsp. gracillima). These are found growing between Jerramungup and Israelite Bay from August to early-October.

The wispy spider orchids from the Filamentosa complex are the next found. One specimen appears to be the Cream spider orchid (Caladenia horistes) whilst a nearly finished specimen could be the Common spider orchid (Caladenia varians).
Our location is found within the recorded distribution of both species, both flower during September, plus their flowers and leaves are of similar appearance. I will leave it for you to decide if they are the same species or not.

As this area was also subject to last summer’s bushfire the next orchid found was as expected.
Red Beaks (Pyrorchis nigricans) flower from August to October between Shark and Israelite Bays.

Last orchid recorded for this location is an unfurling Dancing spider orchid (Caladenia discoidea), which are found flowering from August to early-October between Kalbarri and Israelite Bay.

Location 8 is another random stop along the road. Change of vegetation so we will see if anything new is found.
First orchid located was a donkey orchid, however based on only 1 specimen I will not attempt to ID it at this stage. Will share to iNaturalist for assistance in this regard

The following orchids have all been found previously today and recorded in this blog so I will post 2 pics each only to record they were found in this new location.
Western tiny blue orchid,
Small mantis orchid,
Red Beaks,
Cream spider orchid,
Purple enamel orchid.

Finally, a new orchid for this blog is found.
Nothing special unfortunately but something new is something new.
The Cowslip orchid (Caladenia flava subsp. flava) is widely distributed between Northampton and Israelite Bay flowering from July to early-December

Just as we were heading back to Fili I spied a tall yellow orchid.
Woohoo it is a new orchid for today !!!!!!
The Custard orchid (Thelymitra villosa) grows to 600mm in height and can have up to 20 flowers per plant.
They are found between Northampton and Israelite Bay from September to November.

What a great way to finish off this location.
So, over the 2 random roadside stops we found 10 species of orchids.
Sometimes it pays just to pull over and look.

Off to our final destination of the day.

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 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!!

20/08/2023 ….. Southern Curly-Locks and Pink Bunny Orchid | Orchid Discovery West of Esperance

List of Orchids Found, Sunday Drive, Western Australian Orchids

Earlier this month we ventured east of Esperance, so today we have decided to try the west side of Esperance. It is a few weeks later into the orchid season in Western Australia so we are hopeful of finding many orchids in flower.
First up we check out a recently burnt section of bush near Coomalbidgup. We find so many orchids here that it is over 1hr later before we move on.

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

So, it turned out to be a great Sunday drive where we discovered at least 16 species of orchid. A first for us west of Esperance was the Southern curly-locks, which we have only found east of Esperance previously. Finding the small Pink bunny orchid at numerous locations was our highlight of the day.

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.

08/10/2022 & 09/10/2022 ….. Jacup Jewels

Numerous days, Road Trip, Western Australian Orchids

Upon leaving the Jerramungup burnt are we head east looking for somewhere to park up for the night. We make it about 35kms when we pull into the Jacup Highway Park at the Fitzgerald River crossing. This will do, so we set up the camper and I do my best to drive over a log in my Ford Falcon, not the greatest idea 🙂 I’ve had.

Now we still have the late afternoon to go orchid hunting. As per our previous visit to this location, we are not disappointed. First, we find the Green spider/Fringed mantis orchid (Caladenia falcata) flowering in isolation and in small groups over the entire area we checked out.

Calli extend to mid lobe only
Clubbed sepals
Parent and hybrid child

As can be seen in the picture above the hybrid, Wheatbelt spider orchid (Caladenia x cala) was also found. It was amazing how many were actually found, as we usually find one or two only in each location.

Attractive hybrid
Red hockey stick shaped calli
Regularly found in twins
Standing up to 400mm in height
Long fringe segments to greenish-white, red-tipped labellum
Long pendulous lateral sepals
Another parent and hybrid child

And of course, we also found the other parent for the hybrid. The Stark white spider orchid (Caladenia longicauda subsp. eminens) occurs as far east as Ravensthorpe and grows in open woodlands so seems to fit the bill.

Broad labellum
Broad bases to lateral sepals
May be found in tight groups
Bright white in colour
Labellum yet to curl under

Next, we find the very special Lazy spider orchid (Caladenia multiclavia) which is recorded as occurring between Wongan Hills, Borden and Ravensthorpe. This unusual looking orchid is known for its upright petals and sepals plus the smooth striped labellum with a dense band of bristly headed calli.

Tied up with cobwebs
All sepals and petals held upright
Horizontally held flowers.
Lazing with friends
Greenish-yellow flowers with heavy red striping and shading
Striped diamond shaped labellum
Can stand up to 250mm in height
A mobile labellum – Vertical to Horizontal
Dorsal sepal and petals almost joined.
Lazing in the late afternoon sunshine

We also come across a mixture of other orchids but not in great numbers, so I will record then with only 1 pic each. Firstly, there is the ever-reliable Cowslip orchid (Caladenia flava subsp. flava) and Common mignonette orchid (Microtis media subsp. media). Both are common, widespread orchids. Then the more rarely found, without a recent summer fire, Red Beaks (Pyrorchis nigricans) is discovered with a nine-flower inflorescence. Finally, a pale coloured Pink candy orchid (Caladenia hirta subsp. rosea) and possibly a Ravensthorpe rufous greenhood (Pterostylis leptochila) yet to fully flower are found.

One orchid not expected was the Common dragon orchid (Caladenia barbarossa) which is found flowering between Bindoon and Munglinup. There are only 4 species of dragon orchids, and all are endemic to WA. Only 2 specimens found but still very happy.

Column overlooks the large major callus
Standing up to 300mm in height
Spreading petals and lateral sepals
Distinctive hairy labellum

However, one final orchid is found in decent numbers. The Drooping spider orchid (Caladenia radialis), is found flowering between Northampton and Ravensthorpe from August to October. The labellum can have smooth margins or tiny marginal teeth.

Drooping petals and lateral sepals
Dorsal sepal can be held erect.
Two distinct bands of calli
Dorsal sepal can also droop
Red striped labellum
Stand up to 350mm in height

Back to camp due to the fading light.

We awake to a beautiful sunny morning, have breakfast then decide we will take some time this morning to complete a search down to the river. Fingers crossed for something new.

First up though I will post pictures of those orchids we come across that we also found in our afternoon search yesterday.

Lazy spider orchid (Caladenia multiclavia)

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

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

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