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 had been 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.
One week back at work after our 2022 road trip to Mt Augustus, we need to check out our local orchid haunts. So where to? Let us travel east of Esperance and see what is still flowering in late August.
First up we drive as far east as we will go today and call into our favourite spot along Parmango Road. After parking up, we waste no time as orchids are already spotted.

It is now past 11am, so we move on to our next location, Beaumont Nature Reserve.
We make our way back to the Triton and have ourselves some lunch. It was whilst eating lunch we spied the nice Jug orchids flowering, which was great as prior to this we had only found a Jug orchid that was someone else’s lunch 🙂
From here we head back to Fisheries Road and check out a spot I had checked earlier in the year. Not much found but you never know until you check.
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.

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.
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)
P. recurvaPterostylis sp.E. saccharataC. 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.
Knock up lunch including leftovers from Narembeen Cafe.Mini-Magnum Reward
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.
D. hazeliaeP. recurvaE. saccharataP. sanguineaC. roeiP. setulosa
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.
C. dimidiaP. gracileGibb Rock tank
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.
Turnoff to the cave and The Humps walk trailOpening at the back of the caveHand prints
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. The other orchid may be the Ironcaps spider orchid (Caladenia paradoxa). It is described as having wispy, often pendulous petals and lateral sepals with a white, red striped labellum. (EDIT: Andrew Brown has recorded on my iNaturalist record that he believes my C. paradoxa to be C. dimidia)

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.

This year on our road trip we are heading to Mt Augustus which will take us out of orchid territory, so the days spent orchid hunting will be limited. I will only be posting about the days spent orchid hunting with the rest of the trip summarised at the beginning of the next orchid post.
6.30pm on the 29/07/2022, we head off for our next road trip adventure. We arrive a Geoff and Robyn’s place in Dwellingup around 2.30am for our overnight stay. Next day after a leisurely breakfast we head down to Mandurah to catchup with Sheena, a friend who is over from Scotland. Our old Murray Districts Rural Youth group used this event as a reunion of sorts, so we caught up with old friends and relatives from our younger days, which was awesome. After a wonderful lunch we said our goodbyes and headed up to Perth. We caught up with our daughter and got to cuddle our beautiful granddaughter again. We then moved on to the in-laws where we had dinner and stayed the night.
Sunday and it’s time to head north with our travelling companion Richard. After fuelling up we pull over at our first orchid stop for the day, Bindoon Hill TruckBay/Bus Stop. (Mud Map N 46) This was a previous stop that we camped overnight at, which looking around now, that seemed an interesting choice. We had a quick scout around the area on both sides of the highway and we actually found orchids.
The first orchids found for the trip, are the always reliable Banded greenhoods (Pterostylis vittata) which flower from April through to September. Also found growing in the weeds were brightly coloured donkey orchids. Identification is difficult with 2 species that are known to occur in the Shire of Chittering being contenders. So, they are either the Winter donkey orchid (Diuris brumalis) or the Common donkey orchid (Diuris corymbosa). I’ll let you be the judge.
P. vittataDiuris sp.Diuris sp.P. vittata
Moving on further north, I use Google Maps to spy a possible new location. We miss the turnoff so do a U-turn to pull off the road. We venture into Udumung Nature Reserve for our first every search. We are not disappointed. First up are some more donkey orchids. This time I am more certain of the species due to the reflexed lateral sepals. The Common donkey orchid is noted as sometimes having reflexed and often crossed lateral sepals.
D. corymbosaD. corymbosaD. corymbosa
Next up in close succession three different Pterostylis species are found. First up the Jug orchid (Pterostylis recurva) is found, followed by the Banded greenhood and lastly the Broad-petaled snail orchid (Pterostylis platypetala). This is my first time recording this snail orchid which occurs between Kalbarri and Brookton. It flowers during the months, June through August, in woodland and on the margins of seasonally wet flats and streams.
P. recurvaP. vittataP. platypetalaP. platypetalaP. platypetalaP. platypetala
Moving into the bush further we come across further Pterostylis orchids. First up are bird orchids then another greenhood. Using Atlas of Living Australia (ALA) as reference, the bird orchid will be listed as the Dwarf bird orchid (Pterostylis galgula), which is listed as flowering in August/September between Northampton and Munglinup. The greenhood looks like a Dark banded greenhood (Pterostylis sanguinea) and is listed on the ALA site as occurring here, however in Florabase within the Shire of Chittering a similar looking species, the Coastal banded greenhood (Pterostylis orbiculata) is listed. What are your thoughts on the ID as both flower during the months of July and August.
It is now after 1.30pm, so we decide to move on. A little further north we turn right and head into Mogumber. Not much to be seen here, so we head north up the Bindoon-Moora Road. The planned stop at the nature reserve is abandoned as it does not extend to the road, so we pull over at the intersection of Gillingarra Road, as there was some scrubland that may present a possible orchid habitat. I crossed the railway line on the north side of the road whilst Deb ventured down a track on the southside, parallel to the railway line. I only discovered orchid leaves so headed back to see how Deb faired. By the time I found her, Richard was with her, and she was successful in finding our first spider orchid of the trip. The Common spider orchid (Caladenia varians) is a white to creamy-white orchid, which flowers from July to October over a vast area, Kalbarri to Esperance.
C. variansC. variansC. variansC. variansC. variansC. varians
Along with the many spiders were a few Cowslip orchids (Caladenia flava subsp. flava), Common donkey orchids and another uncertain type of banded greenhood. It’s now nearly 2.30pm, so off we head further north.
C. flava subsp. flavaD. corymbosaPterostylis sp.
We drive through Moora and head up towards Coorow. Just south of Coorow we pull over at Marchagee Nature Reserve for a very quick check, as we are now needing to work out where we will stay the night. Only found another unknown banded greenhood orchid. A storm appears to be building, so I start checking google for somewhere to stay. I telephone up the Three Springs Motel, who luckily have room for the 3 of us. It is only donga accommodation but they serve up some mean food and it was BYO, so I enjoyed my Bundy.
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.

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.

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.

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 🙂
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.
Esperance white spider orchid (Caladenia longicauda subsp. crassa)
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.
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 !!!!
