08/10/2022 ….. Burnt Jerramungup

Numerous days, Road Trip, Western Australian Orchids

OK so we finally arrive at the promised land. The burnt area near Jerramungup. We spend just short of 1hr walking around the burnt-out landscape and find the Red beaks as expected in good numbers, however the other orchids were few and far between. They are recorded below as usual.

Red beaks (Pyrorchis nigricans)

Habitat: Found between Shark and Israelite Bays, growing in sandy, sandy-clay and lateritic soils in forests, woodlands and scrublands. With rare exceptions, plants flower only in the season following a summer fire.

Season: August to October

Red beaks en-masse after the summer fire

Purple enamel orchid (Elythranthera brunonis)

Habitat: Found between Kalbarri and Israelite Bay, growing in sandy, sandy-clay and lateritic soils in forests, woodlands and scrublands.

Season: August to early November

Cowslip orchid (Caladenia flava subsp. flava)

Habitat: Found between Northampton and Israelite bay, growing in sandy, sandy-clay, lateritic and granitic soils in forests, woodlands and scrublands. In inland areas the subspecies is found in isolated populations on granite outcrops and rocky hills.

Season: July to early December

Blue china orchid (Cyanicula gemmata)

Habitat: Found between Kalbarri and Israelite Bay, growing in coastal heaths, open forest and mallee scrubs, on sandy to clay to gravelly loam soils.

Season: August to early November

Green spider / Fringed mantis orchid (Caladenia falcata)

Habitat: Found between Wongan Hills and Jerramungup, growing in woodlands and shrublands on sandy to clay loam soils.

Season: September & October

?? sun orchid (Thelymitra sp.)

Appear to be from the Sienna sun orchid complex due to the broad leaves.

Nearly 3pm and a bit deflated, we move on westwards looking for our overnight location.

17/09/2022 ….. Fishing Trip Findings

Cape le Grand NP, National Parks, Weekend away, Western Australian Orchids

It is the Esperance Offshore Fishing Club Classic and my brother, Geoff and Deb have entered the competition as have friends Bob and Tammy. So, a little group of 6 head out to Dunns Beach for an overnight beach camp, with some to try their luck. I am not a fisherperson so during Saturday afternoon I head into the dunes behind the beach to see if I can locate any orchids. Our son Tim turned up as well to fish into the night.

OK, so into the dunes I head. Immediately behind the first set of dunes the land was flooded, so had to work my way around this to get into the more stabilised dunes where some orchids may be found.

Finally made it to the stabilised dune system, which was densely vegetated, so it proved difficult to transverse. However, I was rewarded with great views, plus I actually found some orchids. Some were finished, others were in bud, but I still found 3 species in flower. I took photos of them all, however they are not great.

Firstly, found is a sole Banded greenhood (Pterostylis vittata) at the end of its flowering cycle. These orchids are known to flower in coastal heath between Perth and Balladonia. Next were orchids in bud, still to flower, which was frustrating. They appear to be Pink fairies (Caladenia latifolia) which are also listed as growing in coastal heath, though over a larger range, Kalbarri to Israelite Bay. Another orchid in bud was one from the Thelymitra genus plus another finished orchid from the Pterostylis genus, which seems to be a Snail orchid.

The next 3 orchids listed were found flowering … So happy to find flowering orchids. The Western tiny blue orchid (Cyanicula aperta) was found first. These small orchids are found between Dumbleyung and Mt Ragged, which seems to be more inland, so finding one in a coastal environment is special. A single Purple enamel orchid (Elythranthera brunonis) is found growing in a tangle of dead branches of a shrub. These bright orchids flower between Kalbarri and Israelite Bay which indicates coastal shrublands are an included habitat. Final orchid for the day was the Lemon-scented sun orchid (Thelymitra antennifera) which is listed as flowering between Shark Bay and Israelite Bay, growing in seasonally wet areas and creek lines, which covers off on the habitat I found it in.

Purple enamel orchid (Elythranthera brunonis)

I was not expecting to find 7 species to record as being located in the stabilised dunes behind Dunns Beach, which is located in Cape Le Grand National Park, which is great as I don’t have many records for that park listed in my previous blogs.

Back at camp the rest had started fishing with a few small fish caught. It was a beautiful sunset as is common out here on the beach, but I never grow tired of them. Deb does catch a nice sized Gummy shark later in the night. We are so spoilt to live in this beautiful and remote part of the country.

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.

04/09/2022 ….. Father’s Day Findings Pt. I

Dempster Head, Esperance, Western Australian Orchids

Father’s Day breakfast enjoyed at my son’s home with his little family. After stuffing ourselves, we all venture up to Dempster Head to walk off the excess joules. 🙂 It is during our walk that we encounter the following orchids.

Spectacled donkey orchid (Diuris conspicillata)

Distribution & Habitat: Restricted to the Esperance area, growing in shallow soil pockets on coastal granite outcrops.

Eastern granite snail orchid (Pterostylis voightii)

Distribution & Habitat: Found between Albany & Israelite Bay, growing in shallow soil pockets on granite outcrops.

White spider orchid ?? (Caladenia sp.)

Unknown species of spider orchid.

Distribution & Habitat: Found between Bremer Bay and Cape Arid, growing in sandy-clay and clay soils in woodlands and shrublands.

Saying goodbye to the kids, grandkids and Deb C, we head north for our next location. Here we check out the burnt patch north of Gibson.

27/08/2022 ….. Out East – Part 1 – Parmango Road

Day Trip, Western Australian Orchids

One week back at work after our 2022 road trip to Mt Augustus, we need to check out our local orchid haunts. So where to? Let us travel east of Esperance and see what is still flowering in late August.

First up we drive as far east as we will go today and call into our favourite spot along Parmango Road. After parking up, we waste no time as orchids are already spotted.

It is now past 11am, so we move on to our next location, Beaumont Nature Reserve.

We make our way back to the Triton and have ourselves some lunch. It was whilst eating lunch we spied the nice Jug orchids flowering, which was great as prior to this we had only found a Jug orchid that was someone else’s lunch 🙂

From here we head back to Fisheries Road and check out a spot I had checked earlier in the year. Not much found but you never know until you check.

19/08/2022 ….. Westonia to Roe Dam

Merredin Peak Reserve, Numerous days, Other Reserves, Road Trip, Western Australian Orchids

We are packed up and ready to leave by 10am on a beautiful sunny day. The Westonia Caravan Park is an awesome place to spend a few nights as the area around has so much to offer. Travelling south to the Great Eastern Highway, we turn west and make our way to Merredin. We decide to check out the reserve around Merredin Peak as this could be a great spot for some orchids. We were not disappointed.

We parked up at the RV Parking area closest to the rock as that was our main focus. However, to ensure we checked out a variety of habitat we venture along the Bush Trail first. (Due to time constraints, we only walked the trail I have highlighted in RED on the above map snip). Excitedly the first orchids found are some spider orchids. A trio of small clumps are found, with all appearing to be the Chameleon spider orchid (Caladenia dimidia), which is a common inland orchid of variable colourings; yellow, cream or pink-red flowers with white or pale-yellow labellum with red markings. Now you can see why these smaller spider orchids are so hard to positively identify.

Nearby we also find a little group of Ant orchids (Caladenia roei) growing. These are cheerful looking orchids, so are also commonly known as Clown orchids. They are a common widespread orchid, being found from Eurardy Station to Ravensthorpe.

Soon enough another spider orchid is found. These have a smooth-edged labellum with dense bands of calli plus the dorsal sepal is drooping. From these features it is the Drooping spider orchid (Caladenia radialis) which is also a common orchid across inland locations, from Northampton to Jerramungup.

Donkey orchids are found at the base of the granite rock growing in the wet areas. The Yellow granite donkey orchid (Diuris hazeliae) is a common inland orchid growing between Paynes Find and Salmon Gums. It is possible some may be a different species. Please let me if you think so.

Up on the rock in the mossy area we luckily find a few small Little laughing leek orchids (Prasophyllum gracile) growing. Not the best photos taken but still a record of their location. These small orchids are very widespread, growing between Shark Bay and Eyre. They grow on granite inland but in scrublands, woodlands and swamps nearer the coast.

Now we did come across many more spider orchids on the track, but I am struggling to identify them confidently. They range in colour, stance and size of both flower and leaf. For that reason, I will post the best pictures taken and will for now just call them Caladenia sp. Any ideas on the actual species please let me know and I will post an edit. EDIT 2 iNaturalist members have agreed they are all colour variations of the Chameleon spider orchid.

We move on as it’s now after 12 and lunch is calling as is the need to get some kilometres driven. Prior to leaving Merredin though we have to grab a look at and take a photo of the painted silos.

Leaving Merredin, we head west along the highway to Hines Hill where we turn south, down Hines Hill Road. It is at the intersection of Jura West Road that we pull over and check out a patch of vegetation. We all head off in different directions and my first orchid found is the common Hairy-stemmed snail orchid (Pterostylis setulosa). Not common here today but some others were found later in the search. Another Pterostylis orchid is found but has already been fertilised and has closed up. The Mallee banded greenhood (Pterostylis arbuscula) is a recently named species which as the name suggests is restricted to mallee regions. It is listed occurring from Dalwallinu to the Eyre Bird Observatory.

Deb as usual has the more exciting find. She comes across some small spider orchids. However, after the initial excitement it appears they are all Chameleon spider orchids. Nice to find, but a new species would have been great.

Chameleon spider orchids in the breeze

And to end the search of the area, a record of the one and only Western tiny blue orchid (Cyanicula aperta) is still to be posted, so here it is. It was found in the middle of all the spider orchids. As the common name suggests, these little guys only grow to 15omm in height and the flowers are 20 – 25 mm across.

Past lunch time and we need something to eat, so off we head into Bruce Rock. Unable to secure a counter meal at the local pub, we venture down to the local cafe, Bruce Rock Cafe (Love that Food) where we were surprised with the choices available. We sat outside to eat as the weather was mild. Well fed, we then move on.

With no real direction planned we head into Narembeen, so that Richard can change his tyre, on a solid flat surface, as the spinout north of Bullfinch seems to have caused the tyre to wear very badly. Narembeen has a great overnight campsite in the town, but we decide to head out to Roe Dam for our last joint overnight camp of the trip. We don’t have the site to ourselves, but we set up as best we can, light a campfire and enjoy the wonderful evening.

18/08/2022 ….. Search of Westonia Shire

Numerous days, Road Trip, Western Australian Orchids

We have booked for 2 nights at the Westonia Caravan Park, so today we plan on checking out some nearby locations for possible orchids. The morning is very cold, in fact, ice has formed on the tonneau cover of Richard’s Triton. We again use the kitchen facilities and enjoy bacon and eggs on avo toast with hollandaise sauce. The sun is shining so we lay out all our wet belongings from yesterday to dry. We head into town first to check out with the shire if their local roads are open. They are all open, so we are able to follow our plan. We next call into a cafe to pick up takeaway lunch for later and a coffee for now, plus some gifts for the grandkids.

Leaving town, we head north to Geelakin Rock, where we find the usual large water tank which is filled by runoff from the granite rock.

In the first patch of bush, we immediately find orchids. First up we find the beautiful Drooping spider orchid (Caladenia radialis) which has a widespread distribution from Northampton to Fitgerald National Park. They are a distinct spider orchid, with usually dropping petals and sepals and a labellum with smooth edges or with a few short fringe elements.

A different species then pops into view. The bright cheerful Blue beard (Pheladenia deformis), is a common widespread orchid which ranges from Kalbarri down to Israelite Bay then eastwards into SA and beyond. It is easy to see where the common name came from, with the many labellum calli.

Amazingly only one snail orchid was found in our search of this rock. The Hairy-stemmed snail orchid (Pterostylis setulosa) is a common inland orchid. Common maybe but my one and only photo is not real good, but I had to record its discovery.

Luckily the next orchid stood out in the grasses however this does not equate to easy identification, especially with these smaller spider orchid species. However, using both Florabase and the Atlas of Living Australia as references, I will be naming theses first spider orchids the Chameleon spider orchid (Caladenia dimidia), which is a common, variable inland species.

Another small spider orchid appears to be the Common spider orchid (Caladenia varians) due to its whiter colouring and pendulous petals and sepals. As the name suggests they are a common orchid which grows between Kalbarri and Esperance.

Then one of the unique types of spider orchids is found. The small Ant orchid (Caladenia roei) is found growing next to one of the Drooping spider orchids. They can grow as high as 300mm however this specimen and others found were much shorter.

After a good 45 mins exploring this rock and surrounds, we decide to move onto our next planned stop, Warrachuppin Rock. At the intersection of the Koorda – Bullfinch Road we pull over at the Warralakin Hall for a photo as it is a rustic corrugated iron building. Warrachuppin Rock unfortunately is behind a fence so we could not reach it and after a quick search around the scrub I only located some Hairy-stemmed snail orchids.

So onwards to our final planned stop of the day, Baladjie Rock. At least this spot is set up for visitors. As expected, the first orchids found are more snail orchids. Some had shorter lateral sepals and less hairy stems, but the location leads me to name them all Hairy-stemmed snail orchids.

After 20 minutes of nothing but the occasional snail orchid I finally find another species for the day growing on the rock. The small Dainty blue orchid (Cyanicula amplexans) is growing in a sheltered nook on the eastern side of the rock. These beautiful little orchids grow between Kalbarri and Norseman during the months of August through October.

Back down on level ground I come across a couple of Ant orchids (C. roei) growing in the cleared patches of the scrub.

Then a trio of spider orchids is discovered, standing in isolation, as no others are found. I am struggling to place a definate ID to these ones. They are most likely more Chameleon spider orchid; however, any ideas would be greatly accepted.

Then another blue orchid comes into view. This lone specimen is a Blue Beard which is a monotypic species. Not great shots taken of this orchid, but I will post 2 images just for the record.

The final species found was the bright yellow donkey orchid. The species found at this location should be the Yellow Granite Donkey Orchid (Diuris hazeliae), so that is what I am identifying these ones as. These are a common inland orchid found from Paynes Find to Salmon Gums.

It’s after 3pm when we finally decide to head back to Westonia. The views from the top of the rock were amazing. This picnic area and rock are not a part of the adjacent Nature Reserve which I find interesting. We enjoy another night at the amazing Westonia Caravan Park.

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.

11/09/2021 ….. Chirelillup Nature Reserve to Jerramungup

Chirelillup NR, Nature Reserves, Numerous days, Road Trip, Toompup NR, Warperup East NR, Western Australian Orchids

After a cool night, instead of packing up camp straight after breakfast, we go exploring the reserve, whilst the camper dries out. I had seen lots of orchids on my quick scout yesterday and now looked forward to having the time to explore with Debbie.

CHIRELILLUP NATURE RESERVE

As per last night the very first orchid found is the Green spider orchid (Caladenia falcata). Also commonly known as the Fringed Mantis orchid.

Then we stumble across a newly named orchid. The Little frog greenhood (Pterostylis occulta) was named in 2021 from specimens collected in 2005, west of Brookton. It is distinguished from P. sargentii by the shape and hairiness of the horn-like structures of the labellum.

Then an old favourite appears just asking us to take a photo. The Cowslip orchid (Caladenia flava subsp. flava) comes in varied shades of yellow. Then the reddish markings can be bold or pale and be dots or lines and everything in between.

Another yellow orchid is then spotted. Donkey orchids are another orchid that can be difficult to identify, as they are all so similar in appearance and overlap in their recorded locations. For this reason I will not attempt to name the ones found here.

Well I find donkey orchids hard to identify, now I need to try and identify spider orchids from the filamentosa complex. I believe some to be the Common spider orchid (Caladenia varians) whilst others may be the Joseph’s spider orchid (Caladenia polychroma) as both are recorded as being located in the Shire of Gnowangerup, and the features seem to match the reference books

An exciting find was the Purple-veined spider orchid (Caladenia doutchiae) which is found between Mullewa and Raventhorpe. The long tapers to the sepals distinguish it from other related orchids.

A common inland orchid is the Sugar orchid (Ericksonella saccharata) however only a few were found at this location. Also found was the ever reliable Jug orchid (Pterostylis recurva), again not in great numbers though.

We ran into some fellow orchid enthusiasts, Martina & Rick, who amazingly follow this blog via Facebook. They shared with us an app on their phone they use to record locations of interest. It also has the ability to overlay geology maps, that show different geology types, which they feel assists them in locating different orchid habitats. I have installed the Australian geology travel maps app and now regularly use it on our excursions.

The camper has now dried out sufficiently so we pack up camp and head off. We detour into Gnowangerup before heading east again. This time we venture into a new location which is not too great a detour off the main track. However we did have to take the Triton and camper through a bit of water to get back to the main Gnowangerup-Jerramungup Road. The water was in the middle of farmland, not the Nature Reserve though.

TOOMPUP NATURE RESERVE

Being a new location, we are excited to see what is found in Toompup Nature Reserve. We pull into an off road parking spot and immediately find some Green spider orchid (Caladenia falcata) which is also referred to as Western mantis orchid. The highly upturned lateral sepals are one of its distinguishing features.

Some small frog greenhoods are located next, however the photos we took are not clear enough to discern the species conclusively. I though, will name them the Little frog greenhood (Pterostylis occulta) due to the sharp of the horn-like structures on the labellum. Please correct me if you think I have erred in this ID.

Some yellow catches our eye. The faithful Cowslip orchid (Caladenia flava subsp. flava) is found. They certainly brighten up the dull West Australian bush.

Vying for having the most yellow in the bush are the donkey orchids, which are also found en masse. To make life difficult three species are recorded as being found in the Shire of Gnowangerup. I will take a guess that some are the Western wheatbelt donkey orchid (Diuris brachyscapa) and some other ones are the Small flowered donkey orchid (Diuris porrifolia). Florabase mentions D. brachyscapa whilst Atlas of Living Australia lists D. brachyscapa and D. porrifolia as being found in this Nature Reserve.

Well we did find some orchids as a single specimen. A flowering Jug orchid (Pterostylis recurva) and Dancing spider orchid (Caladenia discoidea) , a budding Purple enamel orchid (Elythranthera brunonis) and a spent Hare orchid (Leporella fimbriata) were some such finds. Red beaks (Pyrorchis nigricans) and Sugar orchid (Ericksonella saccharata) were found in low numbers.

OK so we find so many different coloured spider orchids from the filamentosa complex that being certain of their identification is proving difficult.

So, I believe most to be the Joseph’s spider orchid (Caladenia polychroma) as they are a common orchid that occurs in variable colours of white, cream, yellow, red and pink. However, the Chameleon spider orchid (Caladenia dimidia) is also a possibility given it occurs in various colours, though it is not currently recorded as occurring in the Gnowangerup LGA.

Some spiders I cannot name are shown opposite. Either the calli are not broad, the colouring seems different, or the size of the flower and labellum don’t fit in with the Joseph’s species. Any help with an ID would be appreciated.

Then to add to the confusion with identification, some hybrids are found together with a lutea or hypochromic specimen.

Parents could be the Purple-veined spider orchid and either Joseph’s or Chameleon spider orchids as both are recorded hybrids.

The lutea or hypochromic specimen appears to be a Joseph’s spider orchid due to the broad calli on the labellum.

Also found were some larger white spider orchids. Now 2 sub-species of C. longicauda are recorded as being found nearby to this location. However, I believe the one I located to be the Stark white spider orchid (Caladenia longicauda subsp. eminens) due to the broad labellum with long fringe segments.

As with the smaller spider orchids, we also came across a couple that did not appear usual. They could just be variants, given the C. longicauda has 4 or more rows of calli. However, the colouring is not stark white either so if you can help with ID, again that would be appreciated.

Finally, time to move on towards Ongerup where we plan to grab a cuppa at the Malleefowl Centre. We came across some water covering the road, so I jumped out and walked through to test the depth. All good, so Deb pushes through and we arrive at the Yongergnow Malleefowl Centre.

Water covers Cleveland Road, so I jumped out and walked through to test the depth. All good, so Deb pushes through in the mighty Triton.

After another amazing cuppa and icecream we make tracks east towards Jerramungup. However along the Gnowangerup-Jerramungup Road we pull over at a patch of green on the map. It turns out to be Warperup East Nature Reserve. So we jump out the Triton and go exploring this new location.

WARPERUP EAST NATURE RESERVE

First up we find the Sugar orchid (Ericksonella saccharata), which has now been found at all 3 locations visited so far today.

Next up find some orchids of the Pterostylis genus. Most are way past their best, but I took photos just to record they are found at this location. Jug orchid (Pterostylis recurva), Banded greenhood (Pterostylis vittata) and Hairy-stemmed snail orchid (Pterostylis setulosa). These orchids all start flowering much earlier in the season.

Other green orchids are found but these belong to the Caladenia genus. First up we find the Small mantis orchid (Caladenia attingens subsp. gracillima), however later on larger flowers are found with longer fringe segments. These could be the Green spider orchid (Caladenia falcata) which occurs as far east as Jerramungup according to my references. The Small mantis orchid is stated as being located as far west as Jerramungup and as we are only 22kms west of Jerramungup both of these species could very well be located here.

Excitedly, we find a new species for the day. The Western tiny blue orchid (Cyanicula aperta) as the name suggests is only 50 – 150mm in height with flowers only 20 – 25mm across. For comparison the Stark white spider orchid is 300 – 600mm in height with flowers 80 -120mm across.

After blue comes the yellow. The reliable Cowslip orchid (Caladenia flava subsp. flava) is the next orchid to be spotted.

Another yellow orchid is also found. The Western wheatbelt donkey orchid (Diuris brachyscapa) is a common orchid found between York, Tenterden and Ravensthorpe. The lateral sepals are said to be crossed hanging, often reflexed, which my pictures confirm.

A special find for this location was the hybrid orchids found. Three in total were found and I believe they are all the named hybrid, Wheatbelt spider orchid (Caladenia x cala). This is a cross between a White spider orchid (C. longicauda) and a Green spider orchid (C. falcata). Hybrids of C. attingens X C. longicauda are also recorded though un-named.

We then move a little further east before pulling up at the location of Needilup. A quick exploration around then takes place with some familiar orchids being found.

NEEDILUP

Well, we only pull over on the side of the road and explore a few meters in. First orchid to catch our eyes was the donkey orchid. Then a lone 2 headed Jug orchid is found, plus lots of Green spider orchids. I feel these ones are definitely Green spiders and not Small mantises due to the size of the labellum.

No more stops before we reach our final destination for the day. Jerramungup is a welcome sight after a long day orchid hunting. We check into the Jerramungup Motor Hotel and enjoy a good pub feed and a comfortable bed. At least 17 different species found with a few hybrids thrown in. A very pleasing day !!!!
