20/08/2022 ….. Roe Dam to Varley

Lake Hurlstone NR, Nature Reserves, Numerous days, Other Reserves, Road Trip, Twine Reserve, Western Australian Orchids

We wake up to a fine, sunny but cold morning. As we are in no rush today, we have breakfast then go exploring the area for orchids, whilst our campers dry out in the sunshine. As we venture toward the granite rock, we discover a large number of Hairy-stemmed snail orchids (Pterostylis setulosa) growing under the sheoaks. Further snail orchids are found later on as well.

Also, at the base of the rock we find a Blue beard (Pheladenia deformis) which stands out in its vibrant blue colouring. Others are found later in the bush surrounding the rock.

From our previous visit to this location, we are aware most of the orchids are found in the bush surrounding the rock however we always have a bit of a climb just in case, plus the views are always amazing from atop these isolated granite outcrops. Usually growing on the rock as well as along the base are the bright yellow donkey orchids. Only a few were located this time round, so the Yellow granite donkey orchid (Diuris hazeliae) is recorded for posterity.

Back on ground level we wander throughout the bush surrounding the rock and immediately come across numerous Drooping spider orchids (Caladenia radialis). These particular spider orchids are so called due to their usually drooping petals and sepals, including the dorsal sepals. They occur between Northampton and Jerramungup and are known to occur in clumps.

Another orchid found in good numbers was the Ant orchid (Caladenia roei) which is a common, widespread orchid. The labellum can range in colour from nearly all green to nearly all red. Their petals and sepals are said to be positioned in a crucifix shape.

Other random orchids were also found growing in the bushland. The common Jug orchid (Pterostylis recurva) and a fertilised ?? Greenhood (Pterostylis sp.) represent their Genus whilst a lone Sugar orchid (Ericksonella saccharata) and a newly unfurled spider orchid (Caladenia sp.) are the representatives for their Genuses. EDIT iNaturalist members have named my spider orchid the Chameleon spider orchid (Caladenia dimidia)

We get back to camp and decide to have an early lunch before packing up the campers. Then Richard pulls out the mini-Magnums as a reward for surviving the adventurous road trip. We then head south and say goodbye at the Mount Walker Road intersection. It is now just Deb and me for the rest of the trip back to Esperance.

We venture further south, making a left turn into Calzoni Road and drive slowly along looking for access to a granite rock I had discovered searching Google Maps. The access road is signposted Twine Reserve. We make our way down and park up to investigate. The rock is covered in pools of water and very thick damp patches of moss. It is growing in this moss that we find our first orchids. The Little laughing leek orchid (Prasophyllum gracile) can grow up to 200mm in height and can have as many as 40 inverted flowers per plant.

We venture back into the vegetation/bush surrounding the rock and come across some more spider orchids. Now for the hard task of identifying them. However, after considering the location and the stance of the orchids they are most likely more Chameleon spider orchids (Caladenia dimida). Please correct me though if I am wrong.

One however did not meet the above criteria due to the size of the leaf and the overall yellow colouring. Please help me to name this one.

Similarly, to Roe Dam, other orchids are found, though usually only a single specimen, so I will record them together again. First up we have a Donkey orchid, then the Jug orchid, Sugar orchid, Greenhood, Ant orchid and Snail orchid are found.

Moving back to Calzoni Road we head east to another chosen location. Gibb Rock is surrounded by farmland and has the obligatory water tank at its base. We park up at the tank and head into the bush at the base. Nothing to be found in the 10 mins of searching so we decide to push on. However, just before reaching the Triton Deb spies a lone Chameleon spider orchid growing in a patch of resurrection bush surrounding a pool of water. Whilst getting photos of this a Little laughing leek orchid also comes into view.

Leaving Gibb Rock, we head south and call into Mulka’s Cave for a look. The handprints were visible which was great, however did not bother with looking for orchids as it was so weedy.

We pass through Hyden and keep heading south, where we finally pull over at Lake Hurlstone Nature Reserve. First up we head across the road to the west and then venture towards the gully. First up we find some colourful donkey orchids. Now using the location as a guide, I feel these orchids are one of two possible species. However, the bright yellow colouring leads me to name them the Yellow granite donkey orchid as they are also found along drainage lines below rocky breakaways, which feels like the habitat we are currently in. The other option, Western wheatbelt donkey orchid, is listed as being pale yellow.

Further along we find some still flowering Dark banded greenhoods (Pterostylis sanguinea) which I am confident to name now, which I was not so with the greenhoods found earlier in the day. They start to flower in June and are recorded as flowering into September.

A couple of Sugar orchid are found, followed by 2 decent Jug orchids. Not many for what can be very common orchids. On the other side of the gully, I stumble across some small spider orchids. Possible two different species found. First up some look like the familiar Chameleon spider orchid and the other orchid may be the Ironcaps spider orchid (Caladenia paradoxa) which is described as having wispy, often pendulous petals and lateral sepals with a white, red striped labellum.

A final small orchid is found over both sides of the road. The Little frog greenhood (Pterostylis occulta) was only named in 2021. It differs to the Frog greenhood by the shape of the horn like structures on the labellum. This was a great little find to end our day.

It is now past 4pm so we grab one last view over the woodland to the lake then jump into the Triton and head down to Varley, where we set up camp in the so-called Chicken Ranch.

04/06/2022 & 06/06/2022 ….. Winter Weekend Camping at Anderson Rocks

Saturday 04/06/2022

We awake to a crisp winters’ morning at the Chicken Ranch in Varley. After a leisurely breakfast, we break camp and head straight for Dempster Rock to look for orchids. Nothing in bloom found. Disappointed, we move on and stop at a new location for us, in the Lake Hurlstone Nature Reserve.

This location may prove fruitful in later stages of the season, as it has a few different habitats to check out. We did locate some orchids this time as well, so all is good. First up appears to be the Mallee banded greenhood (Pterostylis arbuscula) due to its small size and colouring. Further specimens are found with more stem leaves, taller plants and more flowers, so some may be the Dark banded greenhood (Pterostylis sanguinea). I will post pics of all, so please assist with the identification if you can.

Also found lots of spent White bunny orchids, with a lone one still identifiable as such. This one had a crinkled edged stem leaf, so I initially thought it to be the Crinkled-leafed bunny orchid (Eriochilus dilatatus subsp. undulatus) which flowers during April and May, hence why only spent flowers were found, except for this late flowering one of course. However, using Florabase, the only listed bunny orchid found in both the Shire of Kulin and the Shire of Kondinin is the Blunt-leaved bunny orchid (Eriochilus dilatatus subsp. brevifolius) which flower May and June and only have up to 3 flowers. The leaf is also crinkled-edged so I am happy with this identification. Seems subsp. undulatus has been cancelled in Florabase and the common name of Crinkled-leaved bunny orchid given to subsp. brevifolius. The name game is never ending with native orchids. Also found on the way back to the Triton was a nice specimen of the Dark banded greenhood.

Leaving this new location, we head north to Hyden, where we enjoy an amazing hamburger for lunch. As Richard is running late, we make tracks for Anderson Rocks, our planned destination for this long-weekend.

During the weekend I would climb the rock and record the sounds of the frogs in the FrogID App and then attempt to upload my recordings. I received a reply from the Frog ID App on the 20/07/22 advising they had identified 2 species, so my uploads were successful. The species found were the Bleating Froglet (Crinia pseudinsignifera) and Crawling Toadlet (Pseudophryne guentheri).

Monday 06/06/2022

After a great long-weekend camping with Richard, Sandy and Noel at Anderson Rocks, it is time to travel home. As per usual we do not travel home in a straight line and try our best to take roads yet travelled. So, from Hyden we make our way to Allen Rocks Road, where we stop at an old rubbish dump it seems, as there is so much rubbish lying around. We found some old Gest cooldrink bottles and an old enamel pot to add to our collection. The only orchids found here were some yet to fully open shell orchids.

Next stop was on Dragon Rocks Road in the Dragon Rocks Nature Reserve. This roadside stop turned up some Dark banded greenhoods. Then further south on the Newdgate Road North at another roadside stop we only found some spent Pygmy orchids (Corunastylis fuscoviridis) which are also an early flowering orchid.

Final stop for the day other than to fuel up in Lake King and a toilet break in Munglinup. Arrived back in Esperance around 6.15pm and had dinner at our sons’ house, before heading home to unpack. A great weekend but not so great on the orchid front.
