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.
Well, what else do you do on a RDO in spring but go Orchid Hunting. Today we head out east of Esperance in the hope of finding some different species to those found around the lakes and at Helms Arboretum last weekend.
First up we head past Condingup and head north up Parmango Road. At our usual location we slowly drive in, hanging out the windows looking for orchids, then park up and head further in on foot.
At the clearing where we park up, we are surprised to find the beautiful Custard orchid (Thelymitra villosa). This striking orchid flowers during the spring months, over a large range from Northampton to Israelite Bay. It is known to have up to 20 flowers per plant.
Located very close by is the glistening Purple enamel orchid (Elythranthera brunonis). This sun loving orchid flowers from August to early November over a similar range, Kalbarri to Israelite Bay.
Similar sized, petals and sepalsPattern on reverse of petals/sepals showing throughRarely has 3 flowers per plant.
Time to head off on foot as you do find more orchids this way. Backtracking toward Parmango Road first though as Deb spied a bird orchid on the drive in. Only one specimen found and appears to be the Bearded bird orchid (Pterostylis turfosa) as the species named Esperance bird orchid was included as an eastern variety of P. turfosa.
Petals joined forming long pointed hoodDensely hairy labellum – gives common name
Also found here was a smaller yellow orchid. The Bee orchid (Diuris laxiflora) also flowers during the spring months, though only flowers as far northwest as Gingin from Esperance.
Broad labellum mid-lobeYellow, brown marked flowersThis one could be the related Common bee orchid (D. decrementa)
Finally, we head west along the track. A single, solitary Esperance king spider orchid (Caladenia decora) is found. No others were found along this track today. The prominently clubbed sepals allowed me to ID it, as the similarly located and similarly featured Heberle’s spider orchid causes no end of confusion, when trying to ID these king type spider orchids.
4 or more rows of deep red calliProminently clubbed sepals
Another small yellow orchid catches our eye. The tiny Twisted sun orchid (Thelymitra flexuosa), is so named due to a distinctive zig-zagged flower stem. The flowers themselves are listed as being 12 – 15mm across which is smaller than a 5c piece. We have only found this species a couple times before, so this is an exciting find.
Short-crested column with a thickened mid lobeCan have 4 flowers per plant
Amazingly the next orchid is also yellow in colour. The more common Lemon-scented sun orchid (Thelymitra antennifera) which is so named due to the antennae like structures to the column. These orchids flower as far north as Shark Bay from Israelite Bay to our east.
Broad spreading petals and sepalsDark ear-like lateral lobes to column
Finally, an orchid that is not yellow in colour. The striking Common mignonette orchid (Microtis media subsp.media) can stand up to 600mm in height and can have up to 100 yellowish-green flowers per plant. Each flower is miniscule being only 2-3mm across.
The single tube like leaf can be longer than the flower height. Flowers have hood-like dorsal sepals
The surprise find for the day was a solitary hammer orchid, which is well and truly fertilised and slowly shriveling up. The only recorded hammer orchid in the Shire of Esperance is the King-in-his-carriage (Drakaea glyptodon). The distinctly pouched labellum is not apparent, though it may have just shrivelled away.
Narrow hanging petals and lateral sepalsSmooth heart shaped leaf
Another single specimen found. Hiding in a bush the Shy sun orchid (Thelymitra graminea)is living up to its common name. There are four visually similar blue sun orchids flowering in the Esperance district so my identification may be incorrect, so please feel free to enlighten me.
Broad , spreading petals and sepalsColumn has a smooth, yellow crested mid lobe with white tufted lateral lobes
Next up is an orchid that apparently smells bad. As they are so small and close to the ground, I have never put that to the sniff. The White fairy orchid (Caladenia marginata) is an orchid that is stimulated by fire and is usually found around granite outcrops. That is the case for our nearby Cape Le Grand rock location, however no visible granite at this location.
Creamy-white in colourSmall labellum with short fringe segments
Another sun orchid is found in the old damp gravel pit area, however due to the deep cleft in the mid-lobe of the column I believe it to be the Slender sun orchid (Thelymitra vulgaris). They are one of the weird self-pollinating orchids, as are the Twisted sun orchids.
Deep cleft to the mid-lobeNarrow leaf 4 – 8 mm in width – Blurred photo
Next up is a mutated orchid I believe. It appears to be a Lemon-scented sun orchid however it does not have a normal looking column. I would love to have your thoughts on this unusual specimen.
Usual spreading petals and sepalsUnusual structure to column
Another amazing orchid is found poking up through the undergrowth. Rattle beaks (Lyperanthus serratus) in its dull green and maroon colourings is a beautiful orchid. They may have up to 10 flowers per plant and can reach heights of 500mm. They have a distinctive leaf which we regularly find prior to the flowering season but feel blessed when we find one flowering.
Densely hairy yellow-white labellumNarrow petals and lateral sepals
In the gravelly or rocky wet area, we were staggered to find the Pointing spider orchid (Caladenia exstans). We had previously found this orchid at Thomas River and Dempster Head which are in listed habitat of near coastal granite. We are around 25kms from the coast with no apparent granite so did not expect to find these orchids here. Actually, we have also found them at Boyatup which is a similar distance inland but also has granite everywhere.
Further orchids were found but not great photos taken so will record them here and put up the best photo I have of them. Zebra orchid (Caladenia cairnsiana) in a nice bright red form. Dancing spider orchid (Caladenia discoidea) in washed out colours plus the Laughing leek orchid (Prasophyllum macrostachyum) with its beautiful red lined sepals and petals.
Well, this track walked along proved a great spot with many species found. We can’t linger at one place too long so back to the Triton we trudge and onward to our next location.
We pull into Beaumont Nature Reserve which is little further north along Parmango Road. Here we again make our way on foot as the track is too tight and will scratch the crap out of the Triton. It is not long before we find our first orchid. Interestingly it is another Rattle Beaks, closely followed by more Zebra orchids and Bee orchids
Walking further along the track we find other previously found orchids. This time another Purple enamel orchid appears shining in some brief sunlight, further Common mignonette orchids stand tall and yellow Lemon-scented sun orchids are visible against the drying foliage.
Purple enamel orchid (Elythranthera brunonis)Common mignonette orchid (Microtis media subsp. media)Lemon-scented sun orchid (Thelymitra antennifera)
Next up the blue sun orchids start to appear in numbers. From the thin leaf I believe they are further Shy sun orchids and another Slender sun orchid is found, with its deeply clefted column mid lobe. Maybe we will find something new here the further we venture in.

And guess what? We did find something new for the day. From what I can tell this spider orchid appears to be a Hybrid but could also just be a pale coloured Esperance king spider. What are your thoughts?
Prominently red-tipped white labellum4 rows of calliClubbed petals and sepals
Another yellow orchid is found, and it is amazing it has taken this long to find the very widespread common Cowslip orchid (Caladenia flava subsp. flava). These orchids vary greatly in the brightness of their yellow and the patterns of their markings.
Bright yellow with dotsDull yellow with dots and stripe
The next orchid found is confusing as the location would lead the ID to be the Short sepaled spider orchid (Caladenia brevisura), however a lack of clubbing to the lateral sepals seems to indicate the Ant orchid (C. roei)may be the correct ID, but these orchids only go as far East as Ravensthorpe. However, my iNaturalist record has confirmed the first choice.
Down-swept petalsSmooth-margined labellumDense, central band of calli
A new colour for the day appears in the undergrowth. The Pink candy orchid (Caladenia hirta subsp. rosea) is an unexpected find. They are however listed as occurring as far east as Israelite Bay, so should not be a surprise. The pink colouration is varied from very pale pink, almost white to vivid pink.
Spreading petals and sepalsStand up to 250mm in heightUpright labellum with bright pink calli
Talking about a splash of yellow. We have finally reached the granite area with a stream running through it and there is a good number of orchids flowering here. A standout is a great clump of the Elegant donkey orchid (Diuris concinna) which is bright yellow with some small brown markings. This is the best bunch I’ve ever seen.
Slightly brown marked bright yellow flowersForward projecting lateral sepalsStand up to 400mm in height
Flowering nearby was the closely related Common bee orchid (Diuris decrementa) which is known to grow on shallow soil on granite outcrops. They were found in large numbers the more we ventured.
Brown marked labellum and dorsal sepalTop-down viewIntermixed with Blue flowers and Swamp mignonette orchids
As pictured above with the bee orchids was the small Swamp mignonette orchid (Microtis atrata) which as the name suggests are found in seasonally wet flats and run-off areas around granite outcrops. They are only 40 to 80mm in height.
Up to 40 tiny yellowish-green flowersColony forming habitSingle, smooth, tubular leaf
Other orchids were found growing on the shallow soil surrounding the granite, including Rabbit orchids (Leptoceras menziesii) and Lemon-scented sun orchids. Rabbit orchids have ear-like petals that provide the common name and very forward projecting lateral sepals.
Plus of course granite loving orchids are also found. The Granite sun orchid (Thelymitra petrophila) is an inland occurring orchid that flowers from August to November, however, the Coastal sun orchid (Thelymitra granitora) is also recorded as being found on inland granite outcrops northeast of Esperance and flowers during August and September. I think we have found both as the Coastal sun orchid is said to have a fleshy flower stem and the photos do seem to show one with a thicker stem.
Thick fleshy stem (T. granitora)Thinner stem (T. petrophila)Up to 350mm in height (T. petrophila)Up to 200mm in height (T. granitora)
Other orchids found in the woodlands and on the granite were more Common mignonette orchids and Shy sun orchids.
Shy sun orchid (Thelymitra graminea)Common mignonette orchid (Microtis media subsp. media)
The most exciting find at this location was the hybrid of the Lemon-scented sun orchid and one of the blue sun orchids. This hybrid is a wonderful pinkish tone with bright yellow antennae. (Thelymitra x)
Just amazing colours Stance and antennae of T. antinnifera
What a great location this has turned out to be, however, we decide to move on. Next stop is Condingup Hill. (Mud Map SE39) We had barely turned off Fisheries Road when the first orchids are seen. The common Purple enamel orchid comes in first place for this location, closely followed by the small Twisted sun orchid.
Purple enamel orchid (Elythranthera brunonis)Twisted sun orchid (Thelymitra flexuosa)
Next up a king type spider orchid is found. However, I have no idea if it is an Esperance king, Heberle’s or a hybrid. Both the aforementioned species have spreading petals/sepals and with this specimen they are hanging. They appear to be clubbed and particularly thin when compared to the large labellum. Ideas on ID welcome.
White, red tipped labellumClubbed petals and sepalsThin, hanging petals and sepals
Higher up the track at the swampy flat area we find some more Swamp mignonette orchids and a Lemon-scented sun orchid.
Swamp mignonette orchid (Microtis atrata)Lemon-scented sun orchid (Thelymitra antennifera)
At the corner, underneath a bush we are happy to find the Bearded bird orchid in flower. Actually, there is more than one in flower which is great.
We choose not the check out the lookout or Telstra tower area, so we drive back down and look along Fisheries Road just before the Condingup townsite sign. As expected, we locate some Esperance white spider orchids (Caladenia longicauda subsp. crassa) growing in the swampy ground.
Four of more rows of pale red calliStand up to 500mm in heightBroad based petals and lateral sepals
The only other orchids found flowering here were some Purple enamel orchids. So, we grab some quick snaps then jump back into the Triton and head west.
We turn into Ridgelands Road and head north. Stopping at a patch of non-farmland we venture down into what appears to be an area leading to a swamp/lake. The ground is covered in dry leaf litter but growing here and there are some tall sun orchids. Most likely Shy sun orchids again due to location and thickness of the leaf.
Stand up to 350mm in height4-5mm leaf widthBeautiful coloursWhite tufted lateral lobes to columnYellow crested mid-lobe to columnUp to 8 flowers per orchid
Moving to the other side of the road, it is apparent the vegetation is different and straight away we find some Esperance white spider orchids.
4 or more rows of pale red calliBroad, spreading petals and sepalsNarrow fringe segments to labellum
Another, Caladenia species found which occurs between Ravensthorpe and Israelite Bay is the Short sepaled spider orchid. This small spider orchid is distinguished by its south easterly location and short sepal tips which are clubbed. At least these ones have clubs unlike the one found earlier today. There colouring varies considerably from dark red to light green.
A more typical colouring Short, incurved, upright dorsal sepalGreenish colour variantReddish colour variantAlways a red tipped labellum even with colour variantsShort club tipped lateral sepalsSmooth margined labellumDense, central band of dark red calli
Other orchids found include the ever-reliable Cowslip orchid, more Purple enamel orchids, a patch of Elegant donkey orchids and the Common mignonette orchid.
After 4pm, so time to make tracks home. At least 27 orchid species found with a hybrid or 2 thrown in. One last picture to post of a herd of Zebras coz I like it. No other reason!!
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.
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 and move a few hundred metres down the road before stopping at a spot that had seen a bushfire some time in the last year. Let us see if this has triggered orchids to grow for us to find.
Now it nearly 11am so onwards we travel, with our next stop being Talyuberlup Picnic Area. First up we check the picnic area side of the road then we head up the Talyuberlup Peak trail a wee bit, before scrambling back to the triton. As we had hoped, orchids are found.
Spent – Cyrtostylis sp.?? snail orchid (Pterostylis sp.)Little pink fairy (Caladenia reptans subsp. reptans) Jug orchid (Pterostylis recurva)?? donkey orchid (Diuris sp.)Talyuberlup Picnic Area & Trail Head
Time to consider lunch, so we move onwards 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.
Still more of this National Park to check out so onwards 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.
We now head north along Red Gum Pass Road and make a quick stop into the picnic area, where we find a few orchids but move further north to another road side location where orchids are located as well.
We eventually reach Salt River Road and turn right. However we soon pull over at Salt Lake Nature Reserve for an explore, but after a quick check not much is located so we move on to Camel Lake Nature Reserve, with a road side stop along the way. At this final stop we are lucky to find some new orchid species for the day as well as previously found ones. Photos of all those found at the locations along the way were taken 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, set up camp and whilst Deb lights the campfire I have a very quick scout around in the waning sunlight.
Cowslip orchids, Green spider orchid and DaisiesCampsite at Chirelillup Nature ReserveChirelillup Nature Reserve
We awake to a cool morning, so I take Deb around exploring the area whilst the camper dries out. We discover other orchids as well as the ones I found yesterday afternoon, so the wander around was worth the effort.

Well we were not disappointed. At least 22 orchid species found which blows our minds. The bush fire caused devastation, however the regrowth of the Australian bush is amazing. It’s now 4pm so we had better move on and find our overnight camp.
Kingia in flower following the bush fire
We struggled to find a camping location so made the decision to book into one of the Gnowangerup Hotel units for the night. We enjoyed a wonderful bar meal and bevy.
We are collected from our home by Eric and his father, for an orchid adventure out east of Esperance. We will be showing them our Boyatup location ( Mud Map SE 40) and in return we get chauffeured and have the chance to discuss our findings, views, information and thoughts on our beautiful terrestrial orchids. Enjoying the great outdoors by taking nothing but photographs and leaving only footprints.
Our Boyatup location had been affected by bushfire last summer, so this will be our first visit since early August. It will interesting to see which orchids are in flower later in the season after a summer bushfire.
As usual we turn off fisheries Road into the track leading to the rock and jump out once the first orchid is spied. Seen by Deb of course :). Following will be photos taken of the orchids found along this first part of the track.

Lunch time and it’s time we move on. Eric wishes to show us a location where he has previously found the Holy Grail of orchids: Queen of Sheba orchid. He did not have to ask us twice. After having a bite to eat we head off at this new location, just off Parmango Road. Immediately we come across a new orchid, that Deb and myself had never seen. The following orchids are the ones found at this new location, which is now firmly added to our must visit sites.

What a great new location this was off Parmango Road. Time to move on, so we take Eric and his father to our original location off Coolinup road which is on the other side of Condingup. Here we first visit the gravel pit, then decide to bush bash down to our small granite location. The orchids listed below were found on that bush bash plus around the small granite location.
Esperance king spider orchid
Caladenia decora
Laughing leek orchid
Prasophyllum macrostachyum
Heberle’s spider orchid
Caladenia heberleana
Common bee orchid
Diuris decrementa
Bearded bird orchid
Pterostylis turfosa
Purple enamel orchid
Elythranthera brunonis
It proved a very successful day with Boyatup proving itself once again to be a magnificent location for orchids, with this season especially good after last summers bushfire. Thanks to Eric for sharing his Parmango Road location we finally got to see the Twisted sun orchid in bloom and Eric the custard orchid. Nearly 6 hrs spent searching for orchids in great company.
As we came home early from our Road Trip we had to finish our holidays with a final orchid hunt. What better place to check out than Boyatup Hill (Mud Map SE40) . Like Helms Arboretum, Boyatup never disappoints. Arriving at 10am we immediately go exploring for orchids. Our first orchid is the Purple enamel orchid ( Elythranthera brunonis). Closely followed by the small Diuris orchid, from the Bee orchid complex. From the habitat found and the small stature of the plants they appear to be the Common bee orchid (Diuris decrementa).
Pinkish colour variant
Two large, black basal calli
Glossy flowers
Small, yellow, brown marked flowers
Forward projecting lateral sepals
Twins
In close proximity we come across a Red beak (Pyrorchis nigricans), Cowslip orchids (Caladenia flava subsp. flava), more Purple enamel orchids and Common bee orchids.
Distinctive red and white flowers
Up to five flowers per plant
Great family shot
Common, red marked yellow flowers
Then prior to hopping back in the Triton we find some Lemon-scented sun orchids (Thelymitra antennifera) and what appears to be an Esperance king spider orchid (Caladenia decora) nearing the end of it’s season.
Small antennae like column lobes
Stiffly held petals and sepals
We now pass through the gravel pit and head up the track to a spot that allows us to turn around, where we get out have morning tea, then head on up the overgrown track on foot, towards the granite outcrop. Along this overgrown track we find some Pink candy orchids (Caladenia hirta subsp. rosea), more Cowslip orchids and Esperance king spider orchids, plus some of the small, Zebra orchids (Caladenia cairnsiana).
Short, spreading petals and lateral sepals
Twins
Red tipped labellum
Upright dorsal sepal
As mentioned Boyatup is a great location and as proof we have already found 8 varieties in the first half hour of looking. What will a few hours bring? We can’t wait to find out.
Next orchid found was a Pointing spider orchid (Caladenia exstans) which is only found between Esperance and Israelite Bay from September to early November.
Named after the labellum projecting forwards
Smooth margined labellum
More yellow spied. Cowslips and Lemon-scented sun orchids found.
3 is a crowd
Enjoying the sunshine
No scrub will stop them finding the sun
Red colouring is varaible
Then to our surprise we find a Beautiful donkey orchid (Diuris pulchella), very near it’s season end, but still showing off it’s mauve colouring.
The beautiful mauve colouring
Found north and east of Esperance
The further along we walk the more we find. More Zebra, Cowslip, Pink Candy, Pointing spider and Beautiful donkey orchids, then something new for the day. We break out of the overgrown track onto an open, damp, low granite rock space about the size of a soccer pitch and find a Blue china orchid (Cyanicula gemmata ), but exact identification is uncertain as 3 different species can be found in this location.
Short, scattered labellum lamina calli
Mauve-blue to purple flowers
Next orchids found were a small grouping of a Caladenia hybrid. One parent is the Cowslip orchid but deciding the other was proving difficult. The other parent does not appear to be the usual Pink fairy orchids as the dorsal sepal hangs forward over the column, which is a feature of the Pink fans. Reviewing the site esperancewildflowers.blogspot.com.au and the Spider Orchids EBook 2018 it appears the other parent to be the Little pink fan orchid. I would never have picked this due to the recorded location being West of Bremer Bay. So in my research the EBook mentions a hybrid between these two orchids being photographed in Esperance and the Esperance wildflowers blog records finding the Little pink fan orchid within his 160km radius of Esperance. So I am recording these orchids as (Caladenia flava x Caladenia nana) an unnamed hybrid.
Beautiful little hybrid
Forward facing dorsal sepal, typical of C. nana

Colours of both parents
Before leaving this open area we find our smallest orchid of the day. A Laughing leek orchid (Prasophyllum macrostachyum) which is found September through January in a range from Dongara to Cape le Grand. We are 50km East of this range however the flowers appear wider spaced, lateral sepals are shorter and dorsal sepal is wider, than the related Little laughing leek orchid, so I am happy with my classification.
Flowers more widely spaced that the Little laughing leek orchid
Still a very small orchid
The track becomes over grown again and we find a lone spider orchid. Appears to be a Western wispy spider orchid (Caladenia microchila) although this is far from certain
The most Eastern spider orchid
Smaller labellum than other wispy’s
Then we come to the low prickly scrub which leads up to the Granite outcrop. Close to the base of the rock is a thick woodland but for now we are searching in thigh high bushes. Amazingly we find a Rattle Beak (Lyperanthus serratus) growing under one of the bushes bordering the track. Further along we find more Rattle beaks pushing through the prickly shrubs.
Up to 10 dull flowers
Single, long, narrow, leathery leaf 200 – 400mm long by 12-16 mm wide
Densely hairy yellow-white labellum
Narrow forward facing petals and lateral sepals
We don’t have time or inclination to bush bash to the granite rock so after a few more minutes finding further Purple enamel, Pointing spider, Esperance king spider and Zebra orchids we back track to the Triton and move on to another location closer to home, only just.
Big brother watching over
Smooth margined labellum
Striking colours
Flower only 15mm high
On a track named Bebenorin Rd we first come across what appeared to be another Esperance king spider orchid, but on closer inspection I believe it to be a Heberle’s spider orchid (Caladenia herberleana) due to the narrow clubbing of the lateral sepals. These flower September and October in a range from Augusta to Cape Arid which causes them to grow in the same area and at a similar time to the Esperance king spider orchid which makes it difficult to distinguish between them.
Long, slender, rather indistinct petal and sepal clubs
4 or more rows of pale to deep red calli
Red-tipped labellum with long fringe segments
Pale red, white and yellow flowers 60-120mm across
Close by we find some Dancing spider orchids (Caladenia discoidea) and more Cowslip orchids, this time with longer, thinner lateral sepals.
Pale green and red rounded labeluum
Longer thinner lateral sepals than the standard shape
Another first for the day is the Common mignonette orchid (Microtis media) which flowers September through January and ranges from Shark Bay to Eyre, one of the largest ranges of the orchid family in WA.
Curled lateral sepals
Each small flower has a hood like dorsal sepal
Up to 100 yellowish-green flowers
Maybe a pollinator
Getting hungry so we head off to Thomas River for lunch, but not before taking a few more pics.
Awesome coloured tips to the sepals and petals
Wonder where they got the Wispy name from?? LOL
Short spreading petals and sepals
King spider orchid
Side profile
Four rows of squat labellum calli
Nice off centre shot
Large spider orchid flowers 60-120mm across
Just at the entrance to the National Park we find some more Rattle beaks, Lemon-scented sun orchids, Purple enamel orchids and Bee orchids, however only got good pics of the Rattle beaks.
Prominent hood-like dorsal sepal
Spread eagled
We decide to have lunch at the top campground as they have undercover seating. First though we check out the beach and take a walk up the trail for a bit, looking for the patch of leaves we found months earlier. Nothing doing, so we head back to have lunch. On the track in, Deb spies some blue and we are lucky enough to find a solitary Coastal sun orchid (Thelymitra granitora) with a Lemon-scented sun orchid neighbour.
Maroon-tipped flower bract
Column with smooth, yellow-crested mid lobe
Broad spreading petals and sepals
Saying hello
We park the Triton in one of the camping bays and quickly look around, finding a Pointing spider orchid and a King spider orchid, species unknown due to it’s petals and lateral sepals being nibbled off.
Upswept lateral seapls
Petals and lateral sepals nibbled away
After lunch we make our way to the Len Otte nature trail. At the base of the first rise we find a small Laughing leek orchid and further up a some Pink fairies (Caladenia latifolia) and Common bee orchids.
Smooth tubular leaf
Stiffly spreading petals and sepals
Tri-lobed labellum, short fringe segments, two rows calli
Small, yellow, brown marked flowers
Moving through a wooded part of the trail we find some Western wispy spider orchids, before coming out onto the next clearing. Here we get the fright of our life, with a big, black, curled up snake hiding in the low bushes. We keep to the track from now on, no bush bashing, so to speak.
Stiffly held petals and sepals
Two rows of white calli
Birds-eye view of group
OMG this scared us
Now to add to our day the heavens open up and it starts to rain. We try to hurry back but the I see another Blue sun orchid, which appears to be another Coastal sun orchid. Then just as the rain and wind picks up we find some Rabbit orchids (Leptoceras menziesii) in a new location for this nature trail. Photos with it raining and your lenses fogging up, is not an easy task.
Not fully open given the weather
Narrow, erect, ear-like petals
Broad, forward spreading lateral sepals
Up to 5 red and white flowers
Nearby Deb finds a lone Snail orchid. From location and the length of the lateral sepals I am naming it Ravensthorpe snail orchid (Pterostylis sp. ‘ Ravensthorpe’), which is found from Stirling Ranges to Esperance, flowering August and September.
United dorsal sepal and petals forming a blunt hood
Rosette of leaves, 20 to 50mm across
Long, erect lateral sepals, 10 – 25 mm long
Bloated appearance
Still getting wet, but unperturbed, we still search whilst walking quickly back and find some more spider orchids and cowslip orchids. No good photos though, due to rain and fogging lenses, so will not post them. Well this was quite a day of orchid hunting, as our holidays draw to an end. However we did finish on a high – 22 species found in just over 4hours of searching.
