Orchids Found on the Brookton Highway Adventure

Brookton Highway NR, Lake Hurlstone NR, Nature Reserves, Road Trip, State Forest, Western Australian Orchids

31/08/2024

Time to head back to Esperance. I decide to take the Brookton Hwy direction and make my first stop along the highway in the State Forest in the Flint locale.
At this random stop I was extremely lucky to stumble across the Bird orchid (Pterostylis barbata).
This sole specimen though had not yet fully flowered, so its labellum was not visible. Also, the brown markings around where the labellum appears between the body forming petals was not yet evident. However, I am still confident in my identification.

Moving along the highway to the next Flint location¹ in the hope that more species will be found. Parking up off the road I had a quick look around but was driven back to the car by a rain shower.
I did find a nice donkey orchid specimen, however now the difficult task of identifying it. I am leaning toward the Common donkey orchid (Diuris corymbosa) which flowers from August to October.
They are listed as growing between Mogumber and Tenterden in sandy, sandy-clay and lateritic soils in forests, woodlands and shrublands. (Colours differ due to mobile / camera pics)

Another orchid found in this quick search was a Silky blue orchid (Cyanicula sericea) which is distributed between Jurien Bay and Esperance. They occur from August to early-October and is found growing in sandy, sandy-clay and lateritic soils in forests and woodlands. They occur in greater numbers in the season following a summer bushfire.

The rain stopped for a bit so had another quick look and came across a wonderful Jug orchid (Pterostylis recurva).
These orchids are distributed between Geraldton and Israelite Bay growing in sandy-clay and clay soils in woodlands and shrublands.

Final orchid found at this location was the small Little Pink Fairy orchid (Caladenia reptans subsp. reptans) which is distributed between Northampton and Esperance.
They are recorded as growing in a wide variety if habitats; from coastal heath to dry inland woodland in sandy to clay loam to gravelly soils.

Well, I didn’t get far along the highway before I made another stop, this time in Westdale¹. Pulling off the road I make a beeline for the bush I hope to find the Blood spider orchid, as I have found it at this location on a previous visit.
First up though I find some more donkey orchids flowering. Unsure of the ID as they may just be more Common donkey orchids D. corymbosa or may be another species.
I will post to iNaturalist but they are rarely identified on that site either.

Then I stumble across a Green spider orchid (Caladenia falcata) which can also be referred to as the Fringed mantis orchid.
These orchids are distributed between Wongan Hills and Jerramungup growing in a variety of woodland and shrubland habitats, on sandy to clay loam soils.

Then the targeted orchid is found, however in much lower numbers than before. As time is precious, I quickly take some pics of a couple, without exploring further.
The Blood spider orchid (Caladenia filifera) is distributed between Wongan Hills and Tenterden growing in heathy to shrubby woodland and open forest, on clay loam, sometimes gravelly soils.

After successfully finding the Blood spider orchid it was time to move on.
Further along the highway I pull into Jelcobine location⁹, in the Brookton Highway Nature Reserve.
As per today’s previous locations the first orchid found was another donkey orchid. ID is proving difficult as 3 species are recorded in the Atlas of Living Australia for the surrounding area and the dorsal sepal is both erect and recurved in the flowers found.
The options are Diuris brachyscapa, D. porrifolia and D. corymbosa. Any help with identification would be appreciated.

Another yellow-coloured orchid is also found scattered over the location searched. The widespread and common Cowslip orchid (Caladenia flava subsp. flava) is distributed between Northampton and Israelite Bay.
This orchid grows in a wide variety of habitats from wet forest and coastal heath to dry inland woodland, on deep sands to heavy clay loam soils.

Final orchid found at this spot was a solitary Sugar orchid (Ericksonella saccharata) which occurs between Paynes Find and Israelite Bay growing in a variety of habitats including heaths, woodlands, mallee scrubs and granite outcrops, on sandy to clay to gravelly loan soils.

Now as I am writing this blog some 7 mths after the actual date I have forgotten where my final search was completed as it was nearly 3pm, so more than 3 hrs since the previous stop. I did however stop for lunch in Corrigin so feel it was near Hyden. Upon researching Google Maps I have deduced it was at the Lake Hurlstone Nature Reserve stop.

2 species located here were previously found today so I will only post pictures of these. They were the Sugar orchid and Jug orchid.

Donkey orchids were also found and as usual the ID is difficult however based on the location and number of flowers it appears to be the Western wheatbelt donkey orchid (Diuris brachyscapa).
These orchids are found growing between York, Tenterden and Ravensthorpe in woodlands and on and around the margins of granite outcrops.

Next, I stumble across a couple of small spider orchids. They appear to be the Chameleon spider orchid (Caladenia dimidia) which is found between Paynes Find and Norseman growing in seasonally moist areas on granite outcrops, mallee woodlands and slopes to seasonal creeks.

Underneath some bushes I spied some Hairy-stemmed snail orchids (Pterostylis setulosa) still in flower.
These little guys are found between Kalbarri and Balladonia in WA as well as in NSW and SA. They grow in shrublands, woodlands and shallow soil pockets on granite outcrops.

The next stop was another 1hr later so from using maps again I believe I may have pulled into Pallarup Nature Reserve; however, this place is usually full of orchids so not really sure. However, pics were taken so will post them here.
The Midget greenhood (Pterostylis mutica) is found growing in WA between Wongan Hills and the SA border. Also found in QLD, Vic, NSW, Tas and SA.
Grows in shrublands, woodlands and shallow soil pockets in granite outcrops, as it appears many of our orchid do.

Another long drive back to Esperance, though this one was broken up with some fruitful orchid explorations. More than 12 species found, especially given the Donkey orchids found may be a few different species given the distance covered.
This is the last day of Winter down here in Australia, so tomorrow will be Spring and the so-called peak flowering time for WA orchids.

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.

Discovering Unique Orchids on Esperance’s Coast

Esperance, Pink Lake, Western Australian Orchids, Wind Farm

11/08/2024

A beautiful Sunday afternoon in Esperance so what better way to spend it than looking for orchids.
Where to go today though?
Let’s hit some coastal and near coastal locations to see what we find.

First stop is a coastal Esperance location¹⁰

Walking around the marked trail from the car park Deb spies some Snail orchids growing in the scrub. These small orchids appear to be the Southern thick-sepaled snail orchid (Pterostylis meridionalis). They are found in coastal locations between Stokes Inlet and Cape Arid. Flowering from July to September in coastal woodlands and shrublands. If my ID is correct this is only the 2nd time, we have found these, which is exciting.

We now head down the dirt track to toward the granite headland. In the scrubby raised edges to the path, we are pleased to find some helmet orchids. These ones appear to be the Sand hill helmet orchid (Corysanthes despectans) which is found between Bunbury and Israelite Bay. They flower from July to early-September and grow in sandy soils in coastal woodlands and shrublands. They also occur in SA, Vic and Tas.

Now this is a newly discovered species for us so really excited.

Dorsal sepal does not form a hood over labellum

Further down the track we come across more rounded leaves. These leaves, however, end up belonging to the Mosquito orchid (Cyrtostylis robusta). This is a widespread orchid which occurs between Perth and Israelite Bay. These flower earlier so are nearing the end of their season, being June to August.

At the end of the track/s before reaching the granite another species of snail orchid is found. This one is likely to be the Eastern granite snail orchid (Pterostylis voigtii) which flowers from July to September. It occurs between Stokes Inlet and Cape Arid, growing in shallow soil pockets over granite.

Moving onto another coastal location ¹¹ . Here we first find some more snail orchids. Some had the slight clubbing to the lateral sepals whilst others did not. I believe the former are Southern thick-sepaled snail orchids whilst the later are Eastern granite snail orchids. Pics of both recorded.

Deb is excited to find a shell orchid. From the location of the orchid, I believe it to be the Curled-tongue shell orchid (Pterostylis rogersii). These orchids flower from June to August between Binningup and Esperance in coastal woodlands and shrublands. Another one is found nearby which is greener in colour but appears to be the same species.

An orchid found in various shades was the Pink fairies (Caladenia latifolia). A common orchid found between Kalbarri and Israelite Bay, flowering during the months August to December.

Another 3 species of orchid are also found. 1 of which have been found previously today: The Mosquito orchid. Newly found are the rosette of a Bird orchid and the Banded greenhood (Pterostylis vittata). Pictures taken for future reference.

Moving onto our third location for the day.¹² Here a quick inspection turns up some more Curled-tongue shell orchids.

Labellum protrudes giving the common name

Last location of the day provides wonderful views over Pink Lake. ¹³ Here we are amazed to find the Beautiful donkey orchid (Diuris pulchella) growing so close to the coast. I believed it was an inland orchid as it’s range is listed as being between Salmon Gums and Israelite Bay. These stunning orchids flower from July to September.

Another less colourful donkey orchid is also found. Due to our location, I believe this to be the Green Range donkey orchid (Diuris littoralis). Florabase’s map indicates they can occur in coastal locations. Also, their range is listed in my orchid books as being between Denmark and Esperance. The flowering season is July to early-September so it all fits.

Narrow, often crossed lateral sepals. though not is this case.

Further along the track we come across some more Pink fairies. These ones seem to be pink and white striped which is interesting. Also found a lone Snail orchid, ID unknown. Pics take for recording purposes.

Bloated appearance, thin lateral sepals and 2 cauline leaves

The final orchids found for the day were the large white spider orchids. I now need to decide if they are all the Esperance white spider orchid (Caladenia longicauda subsp. crassa) or maybe different species. What are your thoughts?

We spend several hours exploring our coastal and near coastal locations. Then, we return home happy as we have located so many different types of orchids.

The Sand hill helmet orchid being the find of the day.

I’ll finish this post with one of the beautiful scenes we enjoyed today…

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.

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.

31/07/2022 ….. Bindoon to Three Springs

Marchagee NR, Nature Reserves, Numerous days, Road Trip, Udumung NR, Western Australian Orchids

This year on our road trip we are heading to Mt Augustus which will take us out of orchid territory, so the days spent orchid hunting will be limited. I will only be posting about the days spent orchid hunting with the rest of the trip summarised at the beginning of the next orchid post.

6.30pm on the 29/07/2022, we head off for our next road trip adventure. We arrive a Geoff and Robyn’s place in Dwellingup around 2.30am for our overnight stay. Next day after a leisurely breakfast we head down to Mandurah to catchup with Sheena, a friend who is over from Scotland. Our old Murray Districts Rural Youth group used this event as a reunion of sorts, so we caught up with old friends and relatives from our younger days, which was awesome. After a wonderful lunch we said our goodbyes and headed up to Perth. We caught up with our daughter and got to cuddle our beautiful granddaughter again. We then moved on to the in-laws where we had dinner and stayed the night.

Sunday and it’s time to head north with our travelling companion Richard. After fuelling up we pull over at our first orchid stop for the day, Bindoon Hill TruckBay/Bus Stop. (Mud Map N 46) This was a previous stop that we camped overnight at, which looking around now, that seemed an interesting choice. We had a quick scout around the area on both sides of the highway and we actually found orchids.

The first orchids found for the trip, are the always reliable Banded greenhoods (Pterostylis vittata) which flower from April through to September. Also found growing in the weeds were brightly coloured donkey orchids. Identification is difficult with 2 species that are known to occur in the Shire of Chittering being contenders. So, they are either the Winter donkey orchid (Diuris brumalis) or the Common donkey orchid (Diuris corymbosa). I’ll let you be the judge.

Moving on further north, I use Google Maps to spy a possible new location. We miss the turnoff so do a U-turn to pull off the road. We venture into Udumung Nature Reserve for our first every search. We are not disappointed. First up are some more donkey orchids. This time I am more certain of the species due to the reflexed lateral sepals. The Common donkey orchid is noted as sometimes having reflexed and often crossed lateral sepals.

Next up in close succession three different Pterostylis species are found. First up the Jug orchid (Pterostylis recurva) is found, followed by the Banded greenhood and lastly the Broad-petaled snail orchid (Pterostylis platypetala). This is my first time recording this snail orchid which occurs between Kalbarri and Brookton. It flowers during the months, June through August, in woodland and on the margins of seasonally wet flats and streams.

Moving into the bush further we come across further Pterostylis orchids. First up are bird orchids then another greenhood. Using Atlas of Living Australia (ALA) as reference, the bird orchid will be listed as the Dwarf bird orchid (Pterostylis galgula), which is listed as flowering in August/September between Northampton and Munglinup. The greenhood looks like a Dark banded greenhood (Pterostylis sanguinea) and is listed on the ALA site as occurring here, however in Florabase within the Shire of Chittering a similar looking species, the Coastal banded greenhood (Pterostylis orbiculata) is listed. What are your thoughts on the ID as both flower during the months of July and August.

It is now after 1.30pm, so we decide to move on. A little further north we turn right and head into Mogumber. Not much to be seen here, so we head north up the Bindoon-Moora Road. The planned stop at the nature reserve is abandoned as it does not extend to the road, so we pull over at the intersection of Gillingarra Road, as there was some scrubland that may present a possible orchid habitat. I crossed the railway line on the north side of the road whilst Deb ventured down a track on the southside, parallel to the railway line. I only discovered orchid leaves so headed back to see how Deb faired. By the time I found her, Richard was with her, and she was successful in finding our first spider orchid of the trip. The Common spider orchid (Caladenia varians) is a white to creamy-white orchid, which flowers from July to October over a vast area, Kalbarri to Esperance.

Along with the many spiders were a few Cowslip orchids (Caladenia flava subsp. flava), Common donkey orchids and another uncertain type of banded greenhood. It’s now nearly 2.30pm, so off we head further north.

We drive through Moora and head up towards Coorow. Just south of Coorow we pull over at Marchagee Nature Reserve for a very quick check, as we are now needing to work out where we will stay the night. Only found another unknown banded greenhood orchid. A storm appears to be building, so I start checking google for somewhere to stay. I telephone up the Three Springs Motel, who luckily have room for the 3 of us. It is only donga accommodation but they serve up some mean food and it was BYO, so I enjoyed my Bundy.

30/09/2021 ….. RDO romp out East

Beaumont NR, Day Trip, Nature Reserves, Western Australian Orchids

Well, what else do you do on a RDO in spring but go Orchid Hunting. Today we head out east of Esperance in the hope of finding some different species to those found around the lakes and at Helms Arboretum last weekend.

First up we head past Condingup and head north up Parmango Road. At our usual location we slowly drive in, hanging out the windows looking for orchids, then park up and head further in on foot.

At the clearing where we park up, we are surprised to find the beautiful Custard orchid (Thelymitra villosa). This striking orchid flowers during the spring months, over a large range from Northampton to Israelite Bay. It is known to have up to 20 flowers per plant.

Located very close by is the glistening Purple enamel orchid (Elythranthera brunonis). This sun loving orchid flowers from August to early November over a similar range, Kalbarri to Israelite Bay.

Time to head off on foot as you do find more orchids this way. Backtracking toward Parmango Road first though as Deb spied a bird orchid on the drive in. Only one specimen found and appears to be the Bearded bird orchid (Pterostylis turfosa) as the species named Esperance bird orchid was included as an eastern variety of P. turfosa.

Also found here was a smaller yellow orchid. The Bee orchid (Diuris laxiflora) also flowers during the spring months, though only flowers as far northwest as Gingin from Esperance.

Finally, we head west along the track. A single, solitary Esperance king spider orchid (Caladenia decora) is found. No others were found along this track today. The prominently clubbed sepals allowed me to ID it, as the similarly located and similarly featured Heberle’s spider orchid causes no end of confusion, when trying to ID these king type spider orchids.

Another small yellow orchid catches our eye. The tiny Twisted sun orchid (Thelymitra flexuosa), is so named due to a distinctive zig-zagged flower stem. The flowers themselves are listed as being 12 – 15mm across which is smaller than a 5c piece. We have only found this species a couple times before, so this is an exciting find.

Short-crested column with a thickened mid lobe

Amazingly the next orchid is also yellow in colour. The more common Lemon-scented sun orchid (Thelymitra antennifera) which is so named due to the antennae like structures to the column. These orchids flower as far north as Shark Bay from Israelite Bay to our east.

Finally, an orchid that is not yellow in colour. The striking Common mignonette orchid (Microtis media subsp.media) can stand up to 600mm in height and can have up to 100 yellowish-green flowers per plant. Each flower is miniscule being only 2-3mm across.

The single tube like leaf can be longer than the flower height.

The surprise find for the day was a solitary hammer orchid, which is well and truly fertilised and slowly shriveling up. The only recorded hammer orchid in the Shire of Esperance is the King-in-his-carriage (Drakaea glyptodon). The distinctly pouched labellum is not apparent, though it may have just shrivelled away.

Narrow hanging petals and lateral sepals

Another single specimen found. Hiding in a bush the Shy sun orchid (Thelymitra graminea) is living up to its common name. There are four visually similar blue sun orchids flowering in the Esperance district so my identification may be incorrect, so please feel free to enlighten me.

Next up is an orchid that apparently smells bad. As they are so small and close to the ground, I have never put that to the sniff. The White fairy orchid (Caladenia marginata) is an orchid that is stimulated by fire and is usually found around granite outcrops. That is the case for our nearby Cape Le Grand rock location, however no visible granite at this location.

Another sun orchid is found in the old damp gravel pit area, however due to the deep cleft in the mid-lobe of the column I believe it to be the Slender sun orchid (Thelymitra vulgaris). They are one of the weird self-pollinating orchids, as are the Twisted sun orchids.

Next up is a mutated orchid I believe. It appears to be a Lemon-scented sun orchid however it does not have a normal looking column. I would love to have your thoughts on this unusual specimen.

Another amazing orchid is found poking up through the undergrowth. Rattle beaks (Lyperanthus serratus) in its dull green and maroon colourings is a beautiful orchid. They may have up to 10 flowers per plant and can reach heights of 500mm. They have a distinctive leaf which we regularly find prior to the flowering season but feel blessed when we find one flowering.

In the gravelly or rocky wet area, we were staggered to find the Pointing spider orchid (Caladenia exstans). We had previously found this orchid at Thomas River and Dempster Head which are in listed habitat of near coastal granite. We are around 25kms from the coast with no apparent granite so did not expect to find these orchids here. Actually, we have also found them at Boyatup which is a similar distance inland but also has granite everywhere.

Further orchids were found but not great photos taken so will record them here and put up the best photo I have of them. Zebra orchid (Caladenia cairnsiana) in a nice bright red form. Dancing spider orchid (Caladenia discoidea) in washed out colours plus the Laughing leek orchid (Prasophyllum macrostachyum) with its beautiful red lined sepals and petals.

Well, this track walked along proved a great spot with many species found. We can’t linger at one place too long so back to the Triton we trudge and onward to our next location.

We pull into Beaumont Nature Reserve which is little further north along Parmango Road. Here we again make our way on foot as the track is too tight and will scratch the crap out of the Triton. It is not long before we find our first orchid. Interestingly it is another Rattle Beaks, closely followed by more Zebra orchids and Bee orchids

Walking further along the track we find other previously found orchids. This time another Purple enamel orchid appears shining in some brief sunlight, further Common mignonette orchids stand tall and yellow Lemon-scented sun orchids are visible against the drying foliage.

Next up the blue sun orchids start to appear in numbers. From the thin leaf I believe they are further Shy sun orchids and another Slender sun orchid is found, with its deeply clefted column mid lobe. Maybe we will find something new here the further we venture in.

And guess what? We did find something new for the day. From what I can tell this spider orchid appears to be a Hybrid but could also just be a pale coloured Esperance king spider. What are your thoughts?

Another yellow orchid is found, and it is amazing it has taken this long to find the very widespread common Cowslip orchid (Caladenia flava subsp. flava). These orchids vary greatly in the brightness of their yellow and the patterns of their markings.

The next orchid found is confusing as the location would lead the ID to be the Short sepaled spider orchid (Caladenia brevisura), however a lack of clubbing to the lateral sepals seems to indicate the Ant orchid (C. roei) may be the correct ID, but these orchids only go as far East as Ravensthorpe. However, my iNaturalist record has confirmed the first choice.

A new colour for the day appears in the undergrowth. The Pink candy orchid (Caladenia hirta subsp. rosea) is an unexpected find. They are however listed as occurring as far east as Israelite Bay, so should not be a surprise. The pink colouration is varied from very pale pink, almost white to vivid pink.

Talking about a splash of yellow. We have finally reached the granite area with a stream running through it and there is a good number of orchids flowering here. A standout is a great clump of the Elegant donkey orchid (Diuris concinna) which is bright yellow with some small brown markings. This is the best bunch I’ve ever seen.

Slightly brown marked bright yellow flowers

Flowering nearby was the closely related Common bee orchid (Diuris decrementa) which is known to grow on shallow soil on granite outcrops. They were found in large numbers the more we ventured.

As pictured above with the bee orchids was the small Swamp mignonette orchid (Microtis atrata) which as the name suggests are found in seasonally wet flats and run-off areas around granite outcrops. They are only 40 to 80mm in height.

Other orchids were found growing on the shallow soil surrounding the granite, including Rabbit orchids (Leptoceras menziesii) and Lemon-scented sun orchids. Rabbit orchids have ear-like petals that provide the common name and very forward projecting lateral sepals.

Plus of course granite loving orchids are also found. The Granite sun orchid (Thelymitra petrophila) is an inland occurring orchid that flowers from August to November, however, the Coastal sun orchid (Thelymitra granitora) is also recorded as being found on inland granite outcrops northeast of Esperance and flowers during August and September. I think we have found both as the Coastal sun orchid is said to have a fleshy flower stem and the photos do seem to show one with a thicker stem.

Other orchids found in the woodlands and on the granite were more Common mignonette orchids and Shy sun orchids.

The most exciting find at this location was the hybrid of the Lemon-scented sun orchid and one of the blue sun orchids. This hybrid is a wonderful pinkish tone with bright yellow antennae. (Thelymitra x)

What a great location this has turned out to be, however, we decide to move on. Next stop is Condingup Hill. (Mud Map SE39) We had barely turned off Fisheries Road when the first orchids are seen. The common Purple enamel orchid comes in first place for this location, closely followed by the small Twisted sun orchid.

Next up a king type spider orchid is found. However, I have no idea if it is an Esperance king, Heberle’s or a hybrid. Both the aforementioned species have spreading petals/sepals and with this specimen they are hanging. They appear to be clubbed and particularly thin when compared to the large labellum. Ideas on ID welcome.

Higher up the track at the swampy flat area we find some more Swamp mignonette orchids and a Lemon-scented sun orchid.

Swamp mignonette orchid (Microtis atrata)

At the corner, underneath a bush we are happy to find the Bearded bird orchid in flower. Actually, there is more than one in flower which is great.

We choose not the check out the lookout or Telstra tower area, so we drive back down and look along Fisheries Road just before the Condingup townsite sign. As expected, we locate some Esperance white spider orchids (Caladenia longicauda subsp. crassa) growing in the swampy ground.

The only other orchids found flowering here were some Purple enamel orchids. So, we grab some quick snaps then jump back into the Triton and head west.

We turn into Ridgelands Road and head north. Stopping at a patch of non-farmland we venture down into what appears to be an area leading to a swamp/lake. The ground is covered in dry leaf litter but growing here and there are some tall sun orchids. Most likely Shy sun orchids again due to location and thickness of the leaf.

Moving to the other side of the road, it is apparent the vegetation is different and straight away we find some Esperance white spider orchids.

Another, Caladenia species found which occurs between Ravensthorpe and Israelite Bay is the Short sepaled spider orchid. This small spider orchid is distinguished by its south easterly location and short sepal tips which are clubbed. At least these ones have clubs unlike the one found earlier today. There colouring varies considerably from dark red to light green.

Other orchids found include the ever-reliable Cowslip orchid, more Purple enamel orchids, a patch of Elegant donkey orchids and the Common mignonette orchid.

Cowslip orchid (Caladenia flava subsp. flava)

After 4pm, so time to make tracks home. At least 27 orchid species found with a hybrid or 2 thrown in. One last picture to post of a herd of Zebras coz I like it. No other reason!!

12/09/2021 ….. Jerramungup to Munglinup

East Naernup NR, Koornong NR, Nature Reserves, Numerous days, Road Trip, Western Australian Orchids

After an early breakfast we head out to our first location to continue our orchid hunt. Some of the first orchids found are still covered in dew, which exposes the cobwebs as well.

JERRAMUNGUP CEMETERY

Well, I glad we persevered at this location given we found nothing in the first 5 minutes. The hybrid found was our first with a Dragon orchid and the numbers of white spiders was amazing.

However, we must keep moving but we only make it some way up the SouthCoast Highway before pulling into Jacup Highway Park, a rest stop near to the Fitzgerald River crossing. Seems a bit overrun with weeds, but we make the effort and are rewarded big time.

JACUP HIGHWAY PARK

Wheatbelt spider orchid (Caladenia x cala)

After some amazing finds, we jump back into the Triton and head east. We decide to check out another new location and pull over at Koornong Nature Reserve. Some of our finds may be outside the Nature Reserve boundary as the scrubland extends further along the roadside than we were originally aware of.

Koornong Nature Reserve

Four species found, so not too bad a spot. Worthy of a re-visit another time. Next stop is further along the highway. Here we pull into an old bitumen dump and venture into the surrounding scrub. Orchids found 🙂

East Naernup Nature Reserve

It is now way past lunch time, so we head to Munglinup Roadhouse for their amazing burger. Near the roadhouse I find a nice spider orchid and take a photo, which ends up being the last taken for the day.

Our 2021 orchid hunting road trip has come to an end as we head home from Munglinup. As usual it has been amazing to find so many beautiful orchids in the wonderful West Australian bush and woodlands. Many old favourites found as well as some new species, which is always very exciting. Quite a few hybrids found this time as well as a few lutea or polychromic variants.

10/9/2021 ….. Stirling Range National Park to Chirelillup Nature Reserve

Camel Lake NR, Chirelillup NR, National Parks, Nature Reserves, Numerous days, Road Trip, Stirling Range NP, Western Australian Orchids

Well after enjoying our 2nd night at the Stirling Range Retreat, we pack up and head out on our exploration of the Stirling Range National Park. We plan on taking the Stirling Range Drive to Red Gum Pass Road, then north to Salt River Road. Then heading east to Formby Road South where we will head north to Gnowangerup. Obviously we plan on making numerous stops to explore for orchids and to enjoy the wonderful outdoors.

First up we head into Bluff Knoll Road to check out the orchids in one further location. Maybe we will find something different without the threat of rain hanging over our heads. Not surprisingly, the orchids found were the same as the ones found yesterday, but photos were taken again of course.

Warty or Slender hammer orchid ?? (Drakaea sp.)

Nearly 10am, so we make tracks toward our next location. On Stirling Range Drive, we make a split second decision to pull over on the side of the road. We manage to find a few orchids on the side of the road.

We jump back in the Triton. We move a few hundred metres down the road. We stop at a spot that had seen a bushfire sometime in the last year. Let us see if this has triggered orchids to grow for us to find.

Now it nearly 11am so onward we travel, with our next stop being Talyuberlup Picnic Area. First, we check the picnic area side of the road. Then, we head up the Talyuberlup Peak trail a wee bit. Finally, we scramble back to the Triton. As we had hoped, orchids are found.

Time to consider lunch, so we move onward to White Gum Flat picnic area. We have a bite to eat and then go exploring the nearby area. We don’t venture to far before we find orchids. This time round we actually cross the road and find further orchids including new ones for the day. Turns out the King spider orchid is a new species for us, so that was an exciting find.

King spider orchid (Caladenia pectinata)

Still more of this National Park to check out so onward we go. At the intersection of Red Gum Pass Road, we turn left and check out some locations along the roadside. We found a few orchids including some new ones for the day.

Common spider orchid (Caladenia varians)

We now head north along Red Gum Pass Road. We make a quick stop into the picnic area, where we find a few orchids. Then, we move further north to another roadside location where orchids are located as well.

We eventually reach Salt River Road and turn right. We soon pull over at Salt Lake Nature Reserve to explore. After a quick check, we do not locate much. So, we move on to Camel Lake Nature Reserve. We make a roadside stop along the way. At this final stop, we are lucky to find some new orchid species for the day. We also find previously discovered ones. We took photos of all the orchids found at the locations. This was done to record their discovery near the northern boundary of the National Park.

Joseph’s spider orchid (Caladenia polychroma)

Wowsers, they were amazing first time locations for orchids. 13 possible species and 1 hybrid found, however we must move on as it’s past 4.30pm and we still have nearly 50kms to our planned destination. We arrive at Chirelillup Nature Reserve. We set up camp. Whilst Deb lights the campfire, I have a very quick scout around in the waning sunlight.
