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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
