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.

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

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

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

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

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

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

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

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

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

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

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

Chameleon spider orchids dancing in the breeze.

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

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

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

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

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

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

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

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

Joseph’s spider orchid (Caladenia polychroma)

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

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

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

09/07/2022 ….. Afternoon wander Northeast of Esperance

Day Trip, Mount Burdett NR, Mount Ridley NR, Nature Reserves, Western Australian Orchids

Solo again as Deb is still in Perth with Ollie visiting relatives and having a ball. So, after enjoying a sleep in, I have breakfast, do some washing, then pack up and head off for an exploration northeast of Esperance. First stop is on Wittenoom Road at our usual spot (Neridup¹). I immediately check out where the spider orchids flower and was shocked to see the area had been pushed up to increase the space. There was only one small Western wispy spider orchid (Caladenia microchila) Common spider orchid (Caladenia varians) in flower, with no others found, not even leaves. (ID was altered after posting on iNaturalist)

Then I wander around the site, plus also across the road and not too much is flowering. I find some very small donkey orchids which I am not confident to name. Then of course I find the Banded greenhood (Pterostylis vittata) and Dark banded greenhood (Pterostylis sanguinea) growing under the scrub.

And the final orchid found at this location was the small Brittle snail orchid (Pterostylis timothyi) which was hard to photograph due to the wind. So I will post a video of it instead.

Time to move on, but only as far as Scaddan Road, where I pull into a section of reclaimed scrub to see if there is anything flowering. Only found a single greenhood growing as well as some more snail orchids. Both named previously.

Past lunch time, so I head off to Mount Burdett, which is located in the aptly named Mount Burdett Nature Reserve. I parked up halfway as the track is badly washed out, however the view was still great whilst eating my nuts and drinking my coffee. I then walk up the last of the track and first up come across some more snail orchids, but this time they are growing in lush green moss.

Then I hit the usual rock edge where we find most of the orchids on the previous visits. This time however all I find are the faithful Banded greenhoods. This is looking poor, however I push further along the base and come across what appears to be a great patch of non-flowering Pink bunny orchid leaves. Could not see anything flowering though. Just as I was about to head up the hill, I stumble across a small patch of Robust snail orchids (Pterostylis dilatata) which is one of the larger snail orchids and it does not have a rosette, which is quite unique.

Climbing up I come across the Dark banded greenhood again plus a patch of Caladenia leaves. Then found some Hare orchids (Leporella fimbriata) which were in a reasonable state given the listed flowering period is March to June.

Further towards to summit I reach the access track which is very rough and would be a test for your 4WD. At the first turnaround area I discover some further Brittle snail orchids. Then finally at the summit clearing I find a few Green-veined shell orchids (Pterostylis scabra), with only one fully formed. These are a widespread orchid, being found from Kalbarri to Esperance. After taking some pics, I have a quick search for any donkey orchids in flower, but alas none were found. So, it’s back down I head.

Nothing more really comes to my attention before making it back to the Triton. So back to Norwood Road, where I turn right. On the left side of the road, it had been burnt out, so I pull alongside the road, park up, then venture into the blackened scrub. After walking around for about 15 mins, with not an orchid in sight, I despondently jump back into the Triton and head toward Dempster Road. Just before the intersection of the roads, I pull into a layby, which is actually the boundary of the Mount Ridley Nature Reserve. Mount Ridley though is actually some 20kms to the north and is not included in a reserve, which I find bizarre. I decided to check out the reserve bush first, but didn’t get very far in, as it was fairly thick. I did however find some small greenhoods, one of which may be the Midget greenhood (Pterostylis mutica), which commences it’s flowering in July. The I checked out the other side of the road but again, no orchids found. Then just before I reach the Triton, I notice some very spent Pygmy orchid (Corunastylis fuscoviridis), so had to grab a pic for recording purposes.

Moving on, I turn left onto Dempster Road and head south toward Fisheries Road. This part of the road is another boundary of the Nature Reserve, so when another layby catches my eye, I do a U-turn and park up for my final exploration of the day. It is getting dark pretty quickly, but I notice some Dark banded greenhoods and grab some pics, then come across some small rosettes with 3 little buds growing from the bare earth in between. Due to this they are going to be some Shell orchids. I take a pic for record purposes, then make a beeline for the Triton.

Then out of nowhere, hiding under a small bush, a large patch of Dwarf shell orchids (Pterostylis brevichila) catches my eye. Now this is an awesome last find for the day. These wonderful orchids are found from Hyden to Mt Ragged, growing in eucalyptus woodlands. The rosette is listed as being compact with rounded leaves, which confirms the buds found earlier will be more of these.

Time to head home as the light is fading fast, however I pull over to grab a shot of the sunset over one of the many clay pans in the area. Amazing day with 2 species of Shell orchids being found together with other Pterostylis species, A sole Wispy spider orchid represents the Caladenia genus and spent Pygmy and Hare orchids close out the list. Winter is moving on slowly, so we can look forward to more orchids flowering in the weeks to come.

Dempster Road – Sunset over clay pan lake

10/10/2021 ….. Yealering to Newdegate

Malyalling NR, Nature Reserves, Weekend away, Western Australian Orchids

So, we awake in Yealering on the Sunday after enjoying the Regatta on the lake the previous day. We are in the local caravan park with friends Sandy, Noel and Richard. After breakfast we all pack up our respective campers and make our separate way home. For us this will be an excuse to go orchid hunting. Fancy that!!!

I do not have a record in my little black book, and I am writing this record more than 12mths after the fact, so my memory fails me. So, this record will record locations and finds only, with no commentary, which some may find refreshing.

12/09/2021 ….. Jerramungup to Munglinup

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

After an early breakfast we head out to our first location to continue our orchid hunt. Some of the first orchids found are still covered in dew, which exposes the cobwebs as well.

JERRAMUNGUP CEMETERY

Cowslip orchid (Caladenia flava subsp. flava)

Well, I glad we persevered at this location given we found nothing in the first 5 minutes. The hybrid found was our first with a Dragon orchid and the numbers of white spiders was amazing.

However, we must keep moving but we only make it some way up the SouthCoast Highway before pulling into Jacup Highway Park, a rest stop near to the Fitzgerald River crossing. Seems a bit overrun with weeds, but we make the effort and are rewarded big time.

JACUP HIGHWAY PARK

Wheatbelt spider orchid (Caladenia x cala)

After some amazing finds, we jump back into the Triton and head east. We decide to check out another new location and pull over at Koornong Nature Reserve. Some of our finds may be outside the Nature Reserve boundary as the scrubland extends further along the roadside than we were originally aware of.

Koornong Nature Reserve

Four species found, so not too bad a spot. Worthy of a re-visit another time. Next stop is further along the highway. Here we pull into an old bitumen dump and venture into the surrounding scrub. Orchids found 🙂

East Naernup Nature Reserve

Esperance white spider orchid (Caladenia longicauda subsp. crassa)

It is now way past lunch time, so we head to Munglinup Roadhouse for their amazing burger. Near the roadhouse I find a nice spider orchid and take a photo, which ends up being the last taken for the day.

Our 2021 orchid hunting road trip has come to an end as we head home from Munglinup. As usual it has been amazing to find so many beautiful orchids in the wonderful West Australian bush and woodlands. Many old favourites found as well as some new species, which is always very exciting. Quite a few hybrids found this time as well as a few lutea or polychromic variants.

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 !!!!

10/9/2021 ….. Stirling Range National Park to Chirelillup Nature Reserve

Well after enjoying our 2nd night at the Stirling Range Retreat, we pack up and head out on our exploration of the Stirling Range National Park. We plan on taking the Stirling Range Drive to Red Gum Pass Road, then north to Salt River Road. Then heading east to Formby Road South where we will head north to Gnowangerup. Obviously we plan on making numerous stops to explore for orchids and to enjoy the wonderful outdoors.

First up we head into Bluff Knoll Road to check out the orchids in one further location. Maybe we will find something different without the threat of rain hanging over our heads. Not surprisingly, the orchids found were the same as the ones found yesterday, but photos were taken again of course.

Warty or Slender hammer orchid ?? (Drakaea sp.)

Nearly 10am, so we make tracks toward our next location. On Stirling Range Drive, we make a split second decision to pull over on the side of the road. We manage to find a few orchids on the side of the road.

We jump back in the Triton. We move a few hundred metres down the road. We stop at a spot that had seen a bushfire sometime in the last year. Let us see if this has triggered orchids to grow for us to find.

Now it nearly 11am so onward we travel, with our next stop being Talyuberlup Picnic Area. First, we check the picnic area side of the road. Then, we head up the Talyuberlup Peak trail a wee bit. Finally, we scramble back to the Triton. As we had hoped, orchids are found.

Time to consider lunch, so we move onward to White Gum Flat picnic area. We have a bite to eat and then go exploring the nearby area. We don’t venture to far before we find orchids. This time round we actually cross the road and find further orchids including new ones for the day. Turns out the King spider orchid is a new species for us, so that was an exciting find.

King spider orchid (Caladenia pectinata)

Still more of this National Park to check out so onward we go. At the intersection of Red Gum Pass Road, we turn left and check out some locations along the roadside. We found a few orchids including some new ones for the day.

Common spider orchid (Caladenia varians)

We now head north along Red Gum Pass Road. We make a quick stop into the picnic area, where we find a few orchids. Then, we move further north to another roadside location where orchids are located as well.

We eventually reach Salt River Road and turn right. We soon pull over at Salt Lake Nature Reserve to explore. After a quick check, we do not locate much. So, we move on to Camel Lake Nature Reserve. We make a roadside stop along the way. At this final stop, we are lucky to find some new orchid species for the day. We also find previously discovered ones. We took photos of all the orchids found at the locations. This was done to record their discovery near the northern boundary of the National Park.

Wowsers, they were amazing first time locations for orchids. 13 possible species and 1 hybrid found, however we must move on as it’s past 4.30pm and we still have nearly 50kms to our planned destination. We arrive at Chirelillup Nature Reserve. We set up camp. Whilst Deb lights the campfire, I have a very quick scout around in the waning sunlight.

Cowslip orchids, Green spider orchid and Daisies

09/09/2021 ….. Stirling Range National Park and surrounds

Formby NR, Mabinup Creek NR, National Parks, Nature Reserves, Numerous days, Road Trip, Stirling Range NP, Western Australian Orchids

We awake to a cold , wet and miserable day, but we won’t let that stop us from going exploring for orchids. Finally the rain stops, so after a bite of lunch, we head up to the Bluff Knoll lookout however the actual mountain is nearly covered in clouds. The feature picture show some of the amazing metal artwork installed there. Some close-up images are included here for your appreciation.

So now is the time to commence our exploration of the area. We have a very quick scout around the lookout and parking area, where we see a few orchids. However on the drive into the lookout we saw some possible spots to check out along the roadside. So it is at these couple of stops, in between showers, that we locate the following orchids.

It’s now past 2.30pm so we only have a few hours of daylight left to explore, so we will keep close to our base. Therefore we make tracks north of the National Park, to visit the nearby Formby Nature Reserve (Google Maps), which is signposted as the Mabinup Creek Nature Reserve. The northern boundary of the park is found to be very weedy and the creek is overflowing, which does not thrill us too much. So we head back down Formby Road South and venture in on the eastern boundary. Next time we need to pack wellington boots as the place is flooded, but we venture in nonetheless, after applying insect repellent, as the mozzies may become troublesome. This place proves to be covered in orchids in large numbers and many species, which is amazing to us. Refer the following images of the orchids found.

I just had to pop in some photos to show how many orchids were at this location as well as the ones we found swimming.

It is now after 4.30 so we head back toward our base at the Stirling Range Retreat, but as per usual we make one more stop. We pull off the road before the Mount Trio turn-off and head down this gravel track. This is a new location for us in the park and it proves to be quite fruitful. Our quick stop though runs into another hour. Luckily the rain holds off. Here is what we found.

With the light running out fast we do a u-turn, head back to Formsby Road South and make tracks for our little cabin. What an amazing afternoon of orchid hunting we have had today, especially given the cold and wet morning we awoke to. I think we found 23 species and at least 3 hybrids which is mind blowing but this National Park and it’s surrounding are like an oasis in the middle of cleared land for agriculture.

03/09/2021 ….. Northam to Bedfordale Pt2

Beelu NP, National Parks, Nature Reserves, Numerous days, Road Trip, St Ronans NR, Wandoo NP, Western Australian Orchids

After leaving Mokine Nature Reserve we make our way south down Wambyn Road to St Ronans Nature Reserve (Mud Map E 7). We park up at the NW boundary of the park and go exploring. My first orchid found is the Little pink fairy (Caladenia reptans subsp. reptans) which is a rather common orchid flowering between Northampton and Esperance. They are always a pleasure to find though and range from pale to vivid pink in colour.

Also found is a lone Green spider orchid (Caladenia falcata), which is referred to as a common wheatbelt orchid, given its distribution from Wongan Hills to Jerramungup. This specimen stands a good 300mm in height and they are recorded as growing to 400mm in height.

Next up a patch of yellow is seen. Getting closer it is confirmed to be a donkey orchid and appears to be a Small flowered donkey orchid (Diuris porrifolia) which can have up to 7 flowers per orchid. Florabase confirms they are located in the Northam and York shires so the location is covered. The other possibility is the common donkey orchid which is similar though larger in size. Thoughts??

Finally we come across a new orchid for the day. The bright white Sugar orchid (Ericksonella saccharata) is found as two scattered individuals, which is light on when compared to the dozens we have found growing elsewhere in previous seasons. Ericksonella is a another monotypic genus endemic to Western Australia.

The final orchid for this location is another yellow orchid. The reliable Cowslip orchid (Caladenia flava subsp. flava) is found with markings similar to the Brookton Highway cowslip orchid, though this orchid flowers from late September and is located further south. I have read that the boundaries are quite unpredictable with the subspecies but I’m happy to call it the plain cowslip.

We can’t spend an hour at each site, so we move onto Mount Observation in the Wandoo National Park to show Richard what we found here last year. Let’s hope they are flowering this season. On the drive in we spy a nice white spider orchid. I believe it to be the White Spider orchid (Caladenia longicauda subsp. longicauda) which is known to grow in the area and does occur in gravelly ground.

Long pendulous petals and lateral sepals

We then make our way up to the picnic area and park up, to go exploring. Not much around here but we did come across a couple of Blue beards (Pheladenia deformis) which is another monotypic genus, however this time is located along the whole of southern Australia including Tasmania. The most distinctive feature which alludes to the common name, is the dense mass of calli and short fringe segments to the upright labellum.

Walking back to the Tritons, Deb and I come across some Green spider orchids. Then a rocky incline, above the parking area, I find some more Small flowered donkey orchids.

Hidden by a log right where we parked is a couple of Jug orchids (Pterostylis recurva) which are a unique shaped orchid from the Pterostylis genus. They have also been referred to as the Recurved shell orchid, Antelope orchid and Bull orchid.

We now move on and stop at an area we have found other orchids before. The Clubbed spider orchid (Caladenia longiclavata) is again found growing on the verges. As the common names alludes both the sepals and petals are clubbed, with the former being long, thick, grooved clubs and the later small, thin clubs.

However some seem to be the often co-located Big clubbed spider orchid (Caladenia magniclavata) which is distinguished by having down-swept petals and lateral sepals and the clubs to the lateral sepals being approx 50% of the length. The Clubbed spider orchids clubbing is around 30% of the length in comparison.

More Little pink fairies were located as were some awesome Bird orchids (Pterostylis barbata) which are the most widespread of the bird orchids, ranging from Bindoon and Albany. I am amazed at the structure of these orchids with their beak, bloated body and feather duster like labellum.

Also found mixed in with the Clubbed spiders, Big clubbed spiders, Pink fairies and Bird orchids were more Blue beards and Jug orchids.

Finally we move on and close to the end of the track, near the Great Southern Highway we find some more donkey orchids and a Sugar orchid.

Turning south at Mundaring we travel along Mundaring Weir Road and make an on the spot decision to stop at Gungin Gully in the Beelu National Park for our last exploration of the day. We hit the bush and first orchid found is another Jug orchid quickly followed by a Bird orchid. In fact we find so many bird orchids, it is mind blowing.

Another Pterostylis sp. is found amongst the flock of Bird orchids. A small snail orchid is found, however I will not endeavour to name it based on one specimen. If you have any ideas on the ID please contact me.

Another Small flowered donkey orchid is found together with a very finished Hare orchid (Leporella fimbriata). I took photos of both just to record their location.

The highlight of today was finding numerous Silky blue orchids (Cyanicula sericea) which is a common orchid in the western part of its distribution whilst becoming rarer in the eastern parts. Distribution is Jurien Bay to Condingup. The black spotted labellum is a distinctive feature of this orchid.

It’s 3pm so time to make our way to Sandy and Noel’s place in Bedfordale, where we will crash the night. Over the next couple days I train down to Mandurah to visit my mum and sister Maxine, then catch up with the in-laws for a Father’s Day breakfast near the Swan River, then pop up to my brothers place in Dwellingup, where we grab another bed for the night.

Another great day with at least 17 species of orchid found.
