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

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

Exploring the Kepwari Walk Trail: Orchids and Scenic Views

Esperance, List of Orchids Found, Western Australian Orchids, Woody Lake NR

03/09/2024

Today I decide to start the Kepwari Walk Trail from the far eastern end, which is at Lake Wheatfield.
As I did not start this walk till after 4pm I plan on getting to the spot I reached from my walk on the 25/08/2025, before turning back.

Orchids were found over the entire length of the walk, however, were never found in great numbers.
I will just list the orchids in groups of the same species, even if found at different stages of the walk, as my memory will not allow me to provide a more detailed record of the exact locations found.

Cowslip orchid
(Caladenia flava subsp. flava)

Common spider orchid
(Caladenia varians)

Esperance king spider orchid

(Caladenia decora)

Esperance white spider orchid

(Caladenia longicauda subsp. crassa)

Esperance hybrid spider orchid

(Caladenia decora x longicauda)

Small mantis orchid

(Caladenia attingens subsp. gracillima)

I arrived back at the carpark just prior to sunset so took the opportunity to grab some pictures of this amazing sight. A perfect way to end a relaxing afternoon walk in the fresh air.

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.

New Orchid Discovery at Helms Arboretum – 2023 Season Finale Highlights

Esperance, Helms Arboretum, List of Orchids Found, Western Australian Orchids

14/10/2023
Well time stops for no man and the orchid season is nearing its end. For Deb and I this will be our last planned orchid hunt for the season. Later flowers do bloom right though to Feb. However, we call it quits now that the snakes are active, and the orchid pickings are slim.
So, what better place to finish the season than at Helm’s Arboretum? It is a part of the 4000 ha Helms Forestry Reserve.
There is not much of a tale to tell initially. I will just post pictures of the many Sun orchids found flowering.
_{NOTE: Access to Florabase for info on each orchid is linked via the scientific name.}

Slender sun orchid

(Thelymitra vulgaris)

Scented sun orchid

(Thelymitra macrophylla)

Shy sun orchid

(Thelymitra graminea)

Leopard orchid

(Thelymitra benthamiana)

As is normal for Helms there are other species found that are not sun orchids. I will now list these below.

Common mignonette orchid

(Microtis media subsp. media)

Elegant donkey orchid

(Diuris concinna)

Esperance spider orchid – Hybrid

(Caladenia decora x longicauda)

We check out a newer area of the arboretum where the soil is mainly white sand. This is to see if this habitat turns up anything new or more of the same.
OMG we are very excited to find our very first Flying Duck orchids. These orchids belong to their own genus: Paracaleana of which 15 species are found in WA.
4 of which are found in the Shire of Esperance.
From these 4 I feel these to be the Broad-billed duck orchid (Paracaleana triens) which flower Sept-Oct.

Broad-billed duck orchid

(Paracaleana triens)

What a way to end our 2023 Orchid season. We are adding a brand-new orchid to our list of species found.

Roll on the 2024 season!!!!!

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Purple enamel orchid (Elythranthera brunonis)

New orchids for the day were also found at this location. First up is the Zebra orchid (Caladenia cairnsiana) which flowers from August to early-November between Lancelin and Esperance.

Another yellow orchid is found. This time it is the Common bee orchid (Diuris decrementum). It flowers from August to early-October between Wongan Hills and Israelite Bay.

Another pink orchid is found. No not another fairy but a Pink candy orchid (Caladenia hirta subsp. rosea). These orchids flower from late-June to September between Kalbarri and Israelite Bay.

Also found some very pale Pink fairies so just had to share some pics of them. Do not believe they are a hybrid or lutea/hypochromic.

The we come across some donkey orchids. Two different species it seems. Firstly, the distinctive Beautiful donkey orchid (Diuris pulchella) is found. Then a South coast donkey orchid (Diuris brockmanii) is found. The difference in colouring is the major deciding feature.

Next, we come across some of the larger white spider orchids. Based on the location only, I will name one the Esperance white spider orchid (Caladenia longicauda subsp. crassa). As the name suggests they occur both west and east of Esperance. However, the other has a very different labellum with shorter fringe segments. I feel this one is the Reclining spider orchid (Caladenia cruscula). It occurs between Salmon Gums and Mt Ragged.

Esperance white spider orchid (Caladenia longicauda subsp. crassa)

We are amazed to stumble across a large number of hybrids. The parents must be the Pink fairies and Cowslips which we have found at this location. The orchid is therefore the named hybrid Spectacular spider orchid (Caladenia x spectabilis). They do vary in colour quite a bit though. Although the hybrid between Cowslips and the Little pink fairy is very similar. One of the pics below seems quite different to the others. A firm ID may be harder to pin down.

As it’s around 4pm, we decide to move on to our final location. We wish to check if the Bird orchids have flowered yet in the Condingup area.
We are excited to find them in flower. The Bearded bird orchid (Pterostylis turfosa) is a southern species found from Bunbury to Israelite Bay, flowering in spring.

Time to head home to Esperance. It has been an amazing last day of our 2023 road trip. So many orchids found, which makes up for the days in the desert.
So, our adventure ends.
Life is wonderful when spent doing what you love.

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.

Esperance King Spider Orchid

(Caladenia decora)

Cowslip orchid

(Caladenia flava subsp. flava)

Blue beard

(Pheladenia deformis)

Spectacular spider orchid

(Caladenia x spectabilis)

Parents: C. flava / C. latifolia

Lort River snail orchid

(Pterostylis lortensis)

Banded greenhood

(Pterostylis vittata)

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.

Pink bunny orchid

(Eriochilus scaber subsp.scaber)

Reaching spider orchid

(Caladenia arrecta)

(Pheladenia deformis)

Little pink fairy

(Caladenia reptans subsp. reptans)

Banded greenhood

(Pterostylis vittata)

We now move along the highway a bit further westward and pull into a firebreak track. It gets a little boggy, so we don’t venture in far by car, so again go exploring the area on foot. Similar species found with another 2 new for the day.

Little pink fairy

Further west we pull into Munglinup Roadhouse and whilst Deb grabs lunch I go for a wander. After eating our wonderful burgers another nearby location is checked by us both. Orchids found at both spots which is rewarding.

South coast donkey orchid

(Diuris brockmanii)

Cowslip orchid

(Caladenia flava subsp. flava)

Pink bunny orchid

(Eriochilus scaber subsp. scaber)

Stark white spider orchid

(Caladenia longicauda subsp. eminens)

Leaving Munglinup we head southeast to Springdale Nature Reserve. A quick inspection of this location turns up more orchids, including a new species for the day.

South coast donkey orchid

(Diuris brockmanii)

Southern curly-locks

(Thelymitra uliginosa)

Pink bunny orchid

(Thelymitra uliginosa)

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.

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.

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.

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.

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.

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.

Well, this was an amazing first location for the day. Possibly 10 species and 1 hybrid. Let’s see what the rest of the day produces.
