08/10/2022 ….. Warperup East Nature Reserve

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

After leaving Ongerup, the plan was to drive to Jerramungup to check out a burnt-out area we spied on the drive to Albany on Monday, however as per usual we make an unscheduled stop at a new location for us. Warperup East Nature Reserve looked too good an opportunity to just drive by, so after less than 20kms into the drive we turn off, down Corackerup Road and pull over on the roadside to commence our exploration of this area. We spend a good 45mins here checking out various spots along the roadside and were very excited to find our first ever striped sun orchid along with other previously found species.

First orchids found were a couple from the green spider orchid complex. Now due to the calli extending past the mid-lobe of the labellum, I believe these to be the Small mantis orchid (Caladenia attingens subsp. gracillima) which is recorded as being found between Jerramungup (20ish kms to the east of current location) and Israelite Bay and flowers from August to early October, which covers off the date as well. Please correct me if I have wrongly identified the species.

Now for the highlight of this morning. We find many specimens of the beautiful Western azure sun orchid (Thelymitra occidentalis). This orchid is recorded as being common over its southern distribution, Cranbrook to Eyre, however as stated earlier it is our first time finding this orchid, so not common to us. They flower from September to November and can reach 400mm in height, plus may have up to 15 flowers per plant. A beautiful sight indeed.

In the middle of all these Azure sun orchids a Shy sun orchid (Thelymitra graminea) is found. A similar sized orchid though only half the numbers of flowers per plant. These orchids range from Perth to Esperance and flower in October and November.

A much smaller orchid from another genus is the next found. The Ruddy hood (Pterostylis perculta) was previously named after the town of Ongerup, prior to being formally named in 2015. These small orchids are found from the Stirling Range to Thomas River, east of Esperance. They are found growing in rocky soils during September through November.

The Purple enamel orchid (Elythranthera brunonis) is the final orchid we find flowering at this location. These orchids range from Kalbarri to Israelite Bay, flowering from August to early November.

We did actually find one other orchid; however, it is only in bud at this time. It appears to be an orchid from the Sienna sun orchid complex, due to the broad leaf.

Not a bad wing it stop I must say, especially given the find of the Western azure sun orchid. 5 species in total found flowering. Time now to move onto the burnt-out area near Jerramungup.

08/10/2022 ….. Ongerup walkabout

Numerous days, Road Trip, Western Australian Orchids

After not too cold a night we awake to a beautiful day in the Ongerup Gardens Caravan Park. After cereal for breakfast, we decide to go exploring the woodlands behind the caravan park. We take what we believe to be a rough track, but it peters out soon enough, so we go bush bashing in an attempt to find it again. We end up curving north and head up past the sporting complex. We cross Jaekel Steet and follow the track/s to the Yongergnow Malleefowl Centre, where we grab a coffee, for the walk back to the caravan park. The orchid count for such a good walk was a bit disappointing, however we did find some, so I will record them now.

07/10/2022 ….. Lake Toolbrunup & Kebaringup

Anderson Lake NR, Nature Reserves, Numerous days, Road Trip, Western Australian Orchids

Next stop on our winding drive back to Esperance is another new location. Anderson Lake Nature Reserve which is 30kms east as the crow flies from Pootenup Nature Reserve, will hopefully produce some different orchids. As we get close to the location it is apparent that it is much drier so let’s see if we actually find anything at all.

As anticipated, we struggled to find any orchids, however the ones found were indeed different. Very close to where we park, we find our first orchid. The Purple veined spider orchid (Caladenia doutchiae) flowers August through October, between Mullewa and Ravensthorpe. References checked indicate it is found growing on rises around salt lakes, which is exactly the habitat we are currently searching. Four sperate flowers were located, which portray the variable colouring to this species.

Smooth margined, variably coloured, red tipped labellum
Narrow band of labellum calli
Flowers 15 to 30mm across
Purple veins to sepals
Long, shortly clubbed lateral sepals
Short, backswept petals

It was another 15mins or so before we stumbled across another orchid. This time it was the Midget greenhood (Pterostylis mutica) that caught Debs eye. The lime green colouring stands out against the otherwise brown foliage. These small orchids flower July through October, between Wongan Hills and the SA border. They are also found in QLD, NSW, Vic, Tas and SA. Florabase mentions they are known to grow around saline lakes, again confirming we are in suitable habitat.

From the latin MUTICUS (without a point, awn less, blunt) alluding to the blunt petals and sepals.

The next orchid found was a pleasant surprise. First up we thought it was a frog greenhood, but as we settled in to take some photos it became apparent that it was another species. After getting back into the Triton we are excited to note that this is a new species for us. The Ruddy hood (Pterostylis perculta) flowers from late September to early November between Kojonup and Cape Arid National Park. It was only formally named in 2015, previously called sp. “Ongerup’ which alludes to its location. It is a small orchid growing to 150mm in height, may have up to 5 flowers per orchid and is found growing in sandy-clay and clay soils.

Almost hairless labellum
Straight to slightly upcurved lateral sepals
70-150mm in height

As alluded to earlier we had returned to the Triton as this location did not prove overly productive, however finding a new species is always amazing. We head north up to Gnowangerup, then west stopping along the roadside in Kebaringup. I believe this is only our 2nd time visiting this location so we will see what turns up this time.

Straight up the large white spider orchids catch our eye. The Stark white spider orchid (Caladenia longicauda subsp. eminens) is probably the species found, based solely on location. They flower August to early October between Moora and Esperance and can grow to 600mm in height.

Four or more rows of red calli
300 – 600mm in height
Spider on spider orchid

Further orchids are found, though not in great numbers. The Little laughing leek orchid (Prasophyllum gracile) the Cowslip orchid (Caladenia flava subsp. flava) and the Green spider orchid (Caladenia falcata) are all represented by sole specimens.

Cowslip orchid (Caladenia flava subsp. flava)
Green spider orchid (Caladenia falcata)

More Purple veined spider orchids are found in better numbers. Then another single specimen on anorchid is found. The Common mignonette orchid (Microtis media subsp. media) is a widespread orchid being found flowering between Shark Bay and Eyre during the months of September through January. The final orchid found for the day was a good bunch of Jospeh’s spider orchid (Caladenia polychroma), which are found between Boyup Brook and the Fitzgerald River National Park during the months of September and October.

We decide to move on and look for somewhere to stay the night. As we have 2 vehicles and a camper trailer, we make the decision to check into the Ongerup Gardens Caravan Park for the night. It was a choose you own site sort of place, so we parked up close to the ablutions. This was a great day orchid hunting in our wonderful Western Australian outdoors.

07/10/2022 ….. Pootenup Nature Reserve

Nature Reserves, Numerous days, Pootenup NR, Road Trip, Western Australian Orchids

Meeting up with Debbie in Cranbrook this morning. I drove down from Katanning, and she drove up from King River. So, the plan is to take a winding route back to Esperance over the next the next 3 days, with regular stops to search for orchids. After grabbing a cuppa from the Cranbrook store, we head up the Great Southern Highway, but only get as far as Pootenup Nature Reserve, where we pull over for our first exploration. This is a new location, so we are hopeful of finding some orchids.

First up some large Green spider orchids (Caladenia falcata), also called the Fringed mantis orchid, are found with many twins flowering. They can have up to 3 flowers per orchid, so twins are nice to find. They are a common orchid, flowering between Wongan Hills and Jerramungup, from late August to October.

We thought we found a lot of Green spider orchids, but the number of White spider orchids was unbelievable. From the location I feel the large white spider orchids to be the Stark white spider orchid (Caladenia longicauda subsp. eminens), which flowers between Moora and Esperance, during August to early October.

However, some of the white spider orchids are smaller with thinner labellum and shorter fringe segments. After checking the references these ones may be the Tangled white spider orchid (Caladenia longicauda subsp. redacta) which occurs between Collie, Mount Barker and York, growing in sandy-clay soils and seasonally moist flats in forests and woodlands. I will post some pics for you to decide if I am correct in the identification. If not, please let me know.

Other orchids are also found interspersed between all the large green and white spider orchids. A lone Jug orchid (Pterostylis recurva) with 5 flowers in various stages of bloom is one of these. From the reference books having five flowers is somewhat rare, so this is an exciting find, for such a common orchid. Another common orchid found, though not too common at this location, is the Common bee orchid (Diuris decrementum), which is often found growing in clumps and occurs from north of Perth to east of Esperance.

Another common yellow coloured orchid is found but again not common in this location. The Cowslip orchid (Caladenia flava subsp. flava) differs wildly in its markings, as shown by the two specimens found. One has red lines and dots whilst the other is mostly dots. Where the various subspecies overlap these variations cause confusion in making a positive ID.

A hybrid orchid is found which should not have come as a surprise as the probable parents are both found in large numbers. That said, finding a hybrid is always exciting. The named hybrid, Wheatbelt spider orchid (Caladenia x cala) is a cross between the Green spider orchid (C. falcata) and a white spider orchid (C. longicauda).

Another surprise is finding the Pink enamel orchid (Elythranthera emarginata) which is found between Jurien Bay and Ravensthorpe, from October to December. This is a beautiful, bright orchid that grows in sandy, sandy-clay and clay soils in forests, woodlands and shrublands.

Hiding behind the spectacular foursome of Pink enamel orchids you can see some small white orchids. These little beauties are the White fairy orchid (Caladenia marginata), which are found between Jurien and Israelite Bays over the spring months.

Now for the difficult part, trying to ID the smaller spider orchids. The location leads me to believe that the majority of them are the Joseph’s spider orchid (Caladenia polychroma), which is a variably coloured orchid found growing between Boyup Brook and Fitzgerald River National Park during the months of September and October. Listed as growing in woodlands with grassy to herb-rich ground cover, on seasonally damp clay-loam soils.

However, some of the red spider orchids could be the Crimson spider orchid (Caladenia footeana) which is listed as growing between Cranbrook and Binnu, from July through to October. EDIT: Identification via iNaturalist confirms correct ID is the Joseph’s Spider orchid (C. polychroma)

I struggle with identifying some orchids so I will post the pictures with the expectation that someone will advise me what species they believe them to be. Thank you in advance.

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

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.
