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

Orchid Adventures on the Road to Perth

Pallarup NR, Road Trip, Western Australian Orchids

28/08/2024

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

Pink Candy orchid
(Caladenia hirta subsp. rosea)

Sugar orchid
(Ericksonella saccharata)

Frog greenhood
(Pterostylis sargentii)

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

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

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

This orchid has many Common Names

Sugar orchid
(Ericksonella saccharata)

Western wheatbelt donkey orchid
(Diuris brachyscapa)

Chameleon spider orchid
(Caladenia dimidia)

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

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

Orchid 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.

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.

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.

Cowslip orchid (Caladenia flava subsp. flava)
Common mignonette orchid (Microtis media subsp. media)
Pink candy orchid (Caladenia hirta subsp. rosea)
Red beaks (Pyrorchis nigricans)
Ravensthorpe rufous greenhood (Pterostylis leptochila)

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

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

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

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

Back to camp due to the fading light.

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

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

Drooping spider orchid (Caladenia radialis)
Wheatbelt spider orchid (Caladenia x cala)
Stark white spider orchid (Caladenia longicauda subsp. eminens)
Ravensthorpe rufous greenhood (Pterostylis leptochila)
Green spider orchid (Caladenia falcata)
Common mignonette orchid (Microtis media subsp. media)
Lazy spider orchid (Caladenia multiclavia)

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

Bee orchid (Diuris laxiflora)

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.

11/09/2022 ….. Sunny Sunday

Sunday Drive, Western Australian Orchids

What better way to spend a beautiful sunny spring September day that to go exploring for orchids. A decision needs to be made on which direction: North, East, West or maybe a combination.

East wins the day, so off we head directly to Condingup townsite, as we wanted to see if the Drakaea leaves had produced orchids. We were in luck, as the King-in-his-carriage (Drakaea glyptodon) was in flower. These interesting looking orchids are found flowering from Eneabba to Esperance during the months of Aug, Sept and Oct. Condingup is in the Shire of Esperance and approx 70kms east of the Esperance townsite.

More orchids from different genera are found in this location as well. Caladenia is represented by 3 different species. Firstly, the Esperance white spider orchid (Caladenia longicauda subsp. crassa) is found. As the name suggests this orchid ranges from Bremer Bay to Israelite Bay, so includes a vast area of the Esperance shire. Then the equally large Heberle’s spider orchid (Caladenia heberleana) which ranges between Augusta and Cape Arid, is found scattered around. A single specimen of the Western wispy spider orchid (Caladenia microchila) with a wonky labellum is the last species found. These smaller spider orchids are found over a much wider range, from Kondinin and Madura.

Next, we found various orchids, each representing their genus. First up the Purple enamel orchid (Elythranthera brunonis) which ranges from Kalbarri and Israelite Bay. Then the Red beaks (Pyrorchis nigricans) which ranges from Shark Bay to Israelite Bay and finally the Common bee orchid (Diuris decrementa) which ranges from Perth to east of Esperance.

Next location checked is one our spots along Parmango Road, a few clicks east of Condingup. Parking up the Triton, we go for a quick look and find some Common bee orchids and a few Heberle’s spider orchid, which were both located back in Condingup previously.

Not a hugely fruitful location, so we move up a few hundred metres to another favoured location and immediately encounter many more orchids. First up are more Common bee orchids, in good numbers here and further along the track.

Luckily some new species for the day are encountered as well. First up is the Jug orchid (Pterostylis recurva) which is a widespread orchid, being found from Geraldton to Israelite Bay. Then the much smaller Zebra orchid (Caladenia cairnsiana) is found, with these orchids being found between Lancelin and Esperance. Another new species for the day is the ever popular and spectacular Cowslip orchid (Caladenia flava subsp. flava) which is one of the most, if not the most widespread orchid in WA. Including the 4 subspecies, it is found south of the line Shark Bay to Israelite Bay. Then a very local new species is found, the Esperance king spider orchid (Caladenia decora). These orchids are found between Bremer Bay and Cape Arid.

Other new species for the day include the Dancing spider orchid (Caladenia discoidea) and the Lemon-scented sun orchid (Thelymitra antennifera) which both range from north of Geraldton to Israelite Bay. Then some others found previously today are found again, including Red beaks, the Purple enamel orchid and the Western wispy spider orchid.

This was a much better location, with 10 species found, however we need to keep moving. So off to a new location, along Fisheries Road in Howick. We drive slowly down the track and occasionally spy an orchid, at which time we have a scout around for more orchids, before moving on again. This location proves rather fruitful with 8 species found, including 2 new ones for the day. First up I will mention new species found; Beautiful donkey orchid (Diuris pulchella) which is an easterly occurring orchid, found between Salmon Gums, Esperance and Balladonia. The smaller Western tiny blue orchid (Cyanicula aperta) is also found over a larger easterly range, Dumbleyung to Mt Ragged.

The other orchids found at this location were the Cowslip orchid, Western wispy spider orchid, Esperance king spider orchid, Lemon-scented sun orchid, Jug orchid and Esperance white spider orchid.

Now our final location for the day, is one of our favourite spots. The area around Boyatup Hill never disappoints. I will start with the new species for the day, then confirm the findings of those previously found earlier today, as also being located this far east of Esperance.

The Custard orchid (Theymitra villosa) is a nice yellow coloured sun orchid which is found flowering between Northampton and Israelite Bay. Then we have the equally brightly coloured Pink candy orchid (Caladenia hirta subsp. rosea) which flowers slightly further north in Kalbarri then south to Israelite Bay.

Another 2 new species for the day include the Rabbit orchid (Leptoceras menziesii) which is another orchid that ranges from Israelite Bay, but only to Geraldton this time and the Common spider orchid (Caladenia varians) which is listed between Kalbarri and Esperance. The maps do show occurrences east of Esperance; however, I have posted images on iNaturalist asking fellow Citizen Scientists to assist me in identification.

Now to list the orchids previously found at earlier locations, that were also found around Boyatup hill. Purple enamel orchid, Lemon-scented sun orchid, Esperance king spider orchid, Heberle’s spider orchid, Cowslip orchid, Dancing spider orchid, Beautiful donkey orchid, Common bee orchid and a lone fertilised Jug orchid. EDIT: Fellow citizen scientists from my iNaturalist post have advised the Bee orchid (Diuris laxiflora) is the correct ID, so it is not the Common bee, which makes this another species found for the day.

Now you can see why this location is a favourite of ours. With at least 13 species found with a white variant of the Pink candy orchid being a special find. Well, it has been a long day, and we have an hour or so drive home. Time to reflect on the 17 EDIT: 18 species found today, making east of Esperance a special spot for orchids.

21/08/2022 ….. Varley to Esperance – Our 2022 Road Trip Ends

Kathleen NR, Nature Reserves, Numerous days, Pallarup NR, Road Trip, Western Australian Orchids

A leisurely morning today as it is our last one for our 2022 road trip. We enjoyed breakfast whilst listening the raucous Galah flock as they ate on the ground then flew up when spooked into the nearby trees. Our first orchid location was not far away so we were in no rush.

Dempster Rock is our first hunt for the day. As per many locations, the first orchid found is the Hairy-stemmed snail orchid (Pterostylis setuloso), which is a common inland orchid. Only a couple found here and no more were encountered at this location, which is interesting.

We find loads of spider orchids which will as usual prove problematic to identify so firstly I will post the pics of other orchids found first. So the first non-spider orchid found was the common inland occurring Sugar orchid (Ericksonella saccharata) which is found in huge numbers later in the search. I will post some individual pics plus a video showing the large expanse of flowers.

Next up we find some Blue beards (Pheladenia deformis) growing sparsely around the location with one small clump in the early stages of flowering found. It is always nice to find a blue orchid as they are a rare colour for our Southwest orchids.

Another vibrant colour found is pink. The lone Pink candy orchid (Caladenia hirta subsp. rosea) stood out in the green grasses. No others found though, so we thank our lucky stars we came across this specimen.

OK, so now it’s time to record the spider orchid finds. I will start with the easier ones first. The Drooping spider orchid (Caladenia radialis) is a unique spider orchid with usually drooping petals and all sepals, plus has a smooth or slightly fringed labellum.

That’s it for easy ID, now it becomes more difficult. These striking red spider orchids are not recorded as occurring this far southeast. The two that have the closest listed range are the Slender spider orchid and the Red thread spider orchid. Both occur in pure red forms, and both are listed as having pendulous or near pendulous petals and lateral sepals. EDIT: With assistance from members of the FB group Western Australian Native Orchids I am now confident in naming this small clump as being the Slender spider orchid (Caladenia pulchra)

So now the identification gets even more difficult. First up I think these orchids are the Chameleon spider orchid (Caladenia dimidia) due to the backswept petals and whitish colouring to the flowers, however they are variable in colour, so maybe not a great defining feature. 🙂

Now many spider orchids with a creamy to yellow colouring confuse me even more. Some have dark filaments to the ends of the petals and sepals, whilst there are also differences in the colours of the labellum calli. They could be more of the species already identified today or possibly another species. Again, any help in ID would be appreciated.

Chameleon spider orchids dancing in the breeze.

Getting late so we had better move on. We did not get far before pulling into Sugg Rock Road to visit Kathleen Nature Reserve. We just park up on the road verge and head into the reserve to hopefully find some orchids. We do find some but not in great numbers. The first orchid found was another spider orchid, which I believe is another Joseph’s spider orchid. This was followed up by two headed one tangled together. Then yellowish coloured ones are found.

Then we find an orchid that was once included in the Caladenia genus but in Western Australia it has been added to its own monotypic genus, Ericksonella. The Sugar orchid is a distinctive white orchid with horizontally held lateral sepals.

The next three orchids found belong to the genus Pterostylis. First up the ever-reliable Jug orchid (Pterostylis recurva) is found. Then we find a good patch of Midget greenhoods (Pterostylis mutica) growing in numerous spots. Finally, the equally small Little frog greenhood (Pterostylis occulta) which was only named as a distinct species in 2021.

We are getting a pit peckish and plan on a counter lunch at Lake King Tavern, so we push on. However, on reaching the main road we notice a sign pointing west indicating Sugg Rock dam, so we cross the road to check it out. We did not find the dam but decided to check out the bush as it was a bit more open than in the Nature Reserve. We find some familiar orchids so take a photo to record the location and keep searching.

More spider orchids are found which appear to be more Joseph’s spider orchids.

Final couple of orchids found were more Pterostylis ones. A lone greenhood that was fertilised a while ago and a lone good quality shell orchid. The shell orchid is possibly a Green-veined shell orchid (Pterostylis scabra) which flowers May through August over a range from Kalbarri to Esperance.

Now finally it’s time to go and grab some lunch. We enjoy a cold bevvy and hot counter meal at the Lake King Tavern, before heading south to our last planned stop of the 2022 road trip, Pallarup Nature Reserve. Our particular spot is Pallarup Rock picnic area, where we park up and head off on foot to find some orchids. First up the colourful Pink candy orchids are found. Quickly followed up by the Sugar orchids and Blue beards.

Then we moved along the track toward the rock, where we came across some spider orchids. First up were the small Joseph’s spider orchids, however we also found the larger Pallarup white spider orchid (Caladenia longicauda subsp. ‘Pallarup’) which grows over a restricted range between Lake King and Ravensthorpe, growing in sandy soil on the margins of granite outcrops.

Joseph’s spider orchid (Caladenia polychroma)

We venture onto the rock but not much catches our eyes, so we loop back into the surrounding bush and we find more orchids, this time from the Diuris genus. The South-coast donkey orchid (Diuris brockmanii) is found between Ongerup and Esperance during the months of June to August. I feel confident on this ID based on the location and the bright yellow colouring of the flowers, as the other possibility is a pale yellow in colour (D. brachyscapa).

More various orchids found including more Sugar, Bluebeard and Pink Candy orchids, plus a nice Jug Orchid and a very special Lutea or hypochromic candy orchid. As usual Pallarup Rock area always has something flowering during the season. It was a fitting place to end our 2022 Road Trip.

I trust you have enjoyed travelling with us on our 2022 Road Trip which had some exciting, scary, amazing and awe-inspiring times. There was a patch of no orchid hunting but there are areas of this great state of Western Australia that still need to be seen. 2023 will be similar as we venture across the desert to Coober Pedy in South Australia. Well, that is the plan for now.

17/08/2022 ….. Southern Cross to Westonia

Numerous days, Road Trip, Western Australian Orchids, Westonia Common

So, before we get into our day of finding orchids, I need to catch-up on what’s been happening since the last post.

15/08/2022 ….. Early start as Sandy and Noel pack up and head off. A quiet morning is then enjoyed, where I go for a wander around the area near the homestead. The breakaway is amazing with its many colours. Richard then takes us for a drive up to Mt Elvire, well as high as we are game to go that is. The views are amazing. We also have fun fossicking in the black rocks of Lake Barlee.

16/08/2022 ….. I wake early for a change and go out to enjoy the sunrise. Well, that did not happen as the flies were so bad I had to wear the fly net and the sky was grey as, so no sun. It started to drizzle, then the sky grew darker. I woke up Richard and Deb so we could pack up before the rain got heavier. Fail. We pack up wet campers and head off. The track was already getting covered in water, so this will be interesting. We make it back to Evanston-Menzies Road turn west, then south down Evanston-Bullfinch Road. This road soon turned to a slippery hell ride. We could not go over 40km per hr and Richard lost control of his rig and spun 90 degrees on the track, causing damage to both camper trailer and Triton. After checking out his damage on a sealed intersection (mining roads) we take off too slowly and slide into the roadside ditch. One hr later after moving the MaxTrax many times Deb eventually gets the Triton and camper trailer back on the road. A long stressful while later the sealed road returns. Bullfinch not being much of a drawcard we head south to Southern Cross, where we are lucky enough to grab the last available room, a triple, at the Palace Hotel. Hot showers, hot meal, cold beer and warm beds are such a relief after this stressful day.

17/08/2023 ….. Waking up to a beautiful sunny, if somewhat cold day, we chuck our dirty clothes from yesterday into the washing machines, whilst we head across the highway to the local cafe for breakfast. Clothes added to the dryers Deb and I go for a walk around town, whilst Richard does some more cleaning of his rig. Check out at 10am, then we head down to do some extra cleaning as well, buy supplies from the local IGA before heading west towards Westonia.

We arrive at Westonia and grab ourselves two sites in the caravan park. Seems we needed to have booked but luckily for us the young lady who is the live-in caretaker organises for us to remain. After setting up camp we decide to go on the Woodlands & Wildflowers Heritage Walk Trail. Amazingly for us we actually start at Interpretive Sign No.1 and walk in the correct direction. We follow the trail until site 14 is reached, then due to the worsening weather we take the road back to our campers. We are lucky enough though to have stumbled across some orchids. The Hairy-stemmed snail orchid (Pterostylis setulosa) is a common inland orchid and is found growing from July to September. We find them growing singerly plus in small and large groups.

Of course, Deb gets ahead of myself and Richard as I take forever to get my photos. She calls out excitedly as she has found Rufous type greenhoods in various stages of growth, but not flowering. We quickly catchup and there are a few, so I had to grab some shots.

Again, whilst I’m taking photos Deb moves ahead and this time finds some spider orchids. From the creamy yellow colouring I believe these first orchids to be the Chameleon spider orchid (Caladenia dimidia) which flowers from July to September over an inland range, Paynes Find to Norseman.

Easier ones to identify are found next. With the Sugar orchid (Ericksonella saccharata) being first. This is a monotypic genus, so is the only species of its type. They flower August and September over a large area, Israelite Bay to Paynes Find.

Then a different type of spider orchid is found. The unusual Ant orchid (Caladenia roei) is found a couple of times. This little guy flowers from August to October, again over a large range, Eurardy Station to Norseman.

Next up a change in colour is found. The Dainty blue orchid (Cyanicula amplexans) also flowers August to October, over an inland range, Nerren Nerren Station to Norseman. They are also found in pure white form on rare occasions.

Another bright colour is sighted. The Pink candy orchid (Caladenia hirta subsp. rosea) ranges from near white to vivid pink in colour and flowers from late June through to September. They range from Kalbarri to Israelite Bay and occur further inland than the related Candy orchid.

Many more spider orchids were found, with the identification proving difficult. Some have long thin leaves, others are short and thin, whilst others are shortish and wide. Flower colours range from white to cream to pale yellow. Labellum width and markings are also varied between flowers. Many are possibly more Chameleon spider orchids as this species has variable-coloured flowers. Then possible Ironcaps and Glistening spider orchids are found. If you can assist with identification, please make comment.

Some of the orchids were definite Glistening spider orchids (Caladenia incensum) as they have broad, squat white calli and broad leaves. These orchids flower from late June right through to September over an inland range, Hyden to Nerren Nerren Station, which is north of the Murchison River.

Before reaching the road where we decide to head back due to the persistent drizzle, we find another species of orchid. The yellow donkey orchids jump out at us from the dull green, grey foliage. I feel this could be the Mottled donkey orchid (Diuris suffusa) which flowers during August and September in the recorded range, Wongan Hills to Kellerberrin. Our location is some 90kms east of the recorded range so if this ID is incorrect, please let me know.

Walking back along the road we spy more orchids, but as the rain is getting heavier, we do not stop to take any more photos. We enjoy our first night at the Westonia Caravan Park and make use of the campers’ kitchen. Let see what tomorrow brings.

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

Cowslip orchid (Caladenia flava subsp. flava)

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.
