Getting towards the end of the orchid season in the Esperance district, so we decide to go check out the reliable Helms Arboretum (Mud Map SE 35). Prior to this though we have our usual cooked breakfast at the Esperance Bird and Animal Park.
Moving onto the arboretum we first stop along side Plot 23(E) and find some blue sun orchids. Now the tricky bit is naming them as 4 different species flower in the Esperance district. I’m leaning toward the Shy sun orchid (Thelymitra graminea), which grows in woodlands and forests between Perth and Esperance during the months of October and November. They grow up to 350mm in height and have up to 8 flowers in their inflorescences. The colour ranges from dark blue to purple or mauve.
We now move down to the arboretum proper where we hope to find some Leopard orchids in flower. Driving along Boundary X we first come across bee orchids before Deb spies a Leopard orchid (Thelymitra benthamiana) which grows in seasonally moist flats between Northampton and Israelite Bay during the spring months of September through November. Further plants were found flowering along Boundary Z.
The bee orchids also took our attention and we grabbed some photos. From their markings they appear to be the Elegant donkey orchid (Diuris concinna) which grows in moist sites amongst low shrubs between Cape Arid and Fitzgerald River National Park. So a local orchid, which flowers from September to early December.
Moving along we drive down between Plots 85 & 86 as some mignonette orchids were visible from Brockman Road. The Common mignonette orchids (Microtis media subsp. media) grow in scrublands, woodlands and forests between Shark Bay and Eyre. Flowering occurs from September to January with plants growing up to 600mm in height.
We now explore further and locate more of the same, however the sun orchids are larger, with longer inflorescences and more varied in their colour. So I believe they are the Scented sun orchids (Thelymitra macrophylla)which grow in forests and open wandoo woodlands between Perth and Albany, however Florabase shows the Esperance Shire as being a location for this orchid. They flower from August to October and can reach a height of 1000mm with more than 15 flowers per orchid.
It has been a beautiful sunny spring Sunday, so getting out and exploring for orchids was a wonderful way to fill up the morning. However, as Deb starts her shift at 2pm it is time to head home and grab some lunch. Five species found today, with the sun orchids stealing the show, with 2 species from the Blue sun orchid complex and the Leopard orchid, the sole member from the Sienna sun orchid complex. Only 1 month left of spring so we may get to explore for orchids this season, only time will tell.
The orchid below I have not named as the flowers are small, refer blowfly for size comparison, and the stems are reddish coloured and quite thick. Leaves have all been eaten off so no help from them. If anyone can assist with the ID that would be appreciated.
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.

You can tell we are moving into the last few months of the Western Australian orchid season as we only located 9 species over multiple inland locations. The Southwest corner has a much longer season than both the inland and Southeastern areas.
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.
Broad spreading petals and sepalsDistinctive column, with dense orange tufts
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 yesterday spending some time looking for orchids near our coastal lakes, it was inevitable that we would venture out to Helm’s Arboretum (Helm’s Forestry Reserve) to check out what is still flowering in this amazing location. (Mud Map SE35)
We do not have to venture far before we stumble across some orchid beauty. In the section near the entrance, we find the following orchids:

Time is a moving and so must we, so onwards into the Arboretum we go. At the first road to the right, we turn off and slowly drive along looking out the windows. As soon as we spy something new, we pull over for a closer inspection. Along this track we find the following different orchids:

Waking up in the great outdoors and enjoying a hearty breakfast is such a wonderful way to start the day. As we could not find room at the established campground, we need to drive back to the adjoining day use car park for the beginning of the walk trail which heads up the peak. It is along the flat part of this trail that we find our first orchid. One Rufous greenhood (Pterostylis roensis) is found growing under the trees. This is a inland orchid found growing between Mt Jackson and Balladonia in the months of September to November. The relatively short lateral sepals are a distinctive feature.
The trail then commences a climb up the rocks with the ultimate goal of summiting Peak Charles. We however only plan on reaching the plateau between Peak Charles and the smaller mound to the east. We made it to Mushroom rock without finding another orchid which is a bit concerning however we rest for some photo opps then move on up further with hope in our hearts.
Deb locates a patch of mignonette orchids, however only one was in bloom. So I grab a few pics for record purposes and continue up to the plateau. They appear to be the Granite mignonette orchid (Microtis graniticola) due to the location, green coloured flowers and concave dorsal sepal. As the name suggests theses orchids occur on granite outcrops ranging from Mullewa to Balladonia.
Many spent donkey orchids Diuris sp. are found however none still in flower unfortunately. Once we reached the plateau we headed east with the plan to cross over to the other mount. Along the plateau it is devoid of orchids until we find another rufous greenhood in the throngs of opening up.
It is over 1 hr since we found the first orchid then excitedly we stumble across the small Sigmoid spider orchid (Caladenia sigmoidea) growing under some protective bushes. These wonderful little spider orchids are found inland between Mt Jackson to Mt Ragged. They only grow to 150mm in height and are distinguished by their S-shaped labellum apex.
Well the gully between the 2 mounts is deeper than we remember so we back track down the hill to follow the base of the rock around and then climb back up the 2nd mount.
Pushing our way onto the next mount we come across some other rufous greenhoods. Different species though this time. From my research I believe them to be the Striped rufous greenhood (Pterostylis zebrina) which occurs on granite outcrops from Merredin to Mt Ridley.
Deb is onto her spotting as usual and comes across a small patch of Shy greenhoods (Pterostylis allantoidea) which are a very distinctive orchid. Prominently extended dorsal sepal produces a pointed hood over a thick sausage like labellum. Found over a triangular range between Coolgardie, Raventhorpe and Israelite Bay.
Hidden under the same bush as the Shy greenhoods was a green coloured rufous greenhood. Solely due to the bright green colouring I am naming this one the Green spooned-lipped rufous greenhood (Pterostylis virens) as most others are green-brown or similar variations. If I had taken a photo of the labellum, this may have confirmed or otherwise my identification.
Over the remainder of the time we searched, the only orchids found were many more rufous greenhoods, of possible different species. Tough job trying to name these orchids. Assistance would be greatly received.
Nearing 1pm so we decide to head back down to the Triton and drive back to camp for some lunch and a quiet afternoon relaxing.
Very pleased to have found the Sigmoid spider orchids, however disappointed at the lack of Donkey orchids and other spider orchid species. It definitely was the day of the rufous greenhood complex orchids, which was wonderful.
On my drive back in from the airport, after flying back from Melbourne via Perth, I stop in at Helms Arboretum (Mud Map SE 35) to have a quick look around. Only 2 orchids found due to the limited time available.

This lightning visit turns out to be my final orchid adventure for the 2019 season. Highlights were numerous and I will miss many, however some I remember whilst writing this final blog for the season were:
First time finds: Twisted sun orchid, Tenterden yellow spider orchid, Karri snail orchid, common bunny orchid and others.
Hybrids : Northern sandplain spider orchid (1st time find as well), Dusky fairy orchid, Spectacular spider orchid and other un-named ones.
Summer bushfire blooms : Rabbit orchids, Blue beards, Red beaks and Pink bunny orchids in Boyatup.
New Locations discovered : Narembeen shire, Westonia shire, Mukinbudin shire, Mount Marshall shire and Perenjori shire to name a few.
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.

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.

Prasophyllum macrostachyum
Heberle’s spider orchid
Caladenia heberleana

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.
Whilst on a fishing trip to the beaches of Cape le Grand National Park I take some time to check out the vegetation behind the dunes to see if I am lucky enough to find any orchids. In a patch of shallow soil overlaying limestone rock, which was trickling with water, I was lucky to find some Purple enamel orchids (Elythranthera brunonis). I also found close by a Yellow sun orchid yet to open and a large leaf from unknown orchid.
Can have up to 3 flowers per plant
Found around 200m behind the high tide mark in a shallow dune system
Missed getting a shot when this one was open
Possible orchid leaves

Next fishing trip is to a place named Margaret Cove, which is west of Esperance in the Stokes National Park. Again I decide to talk a walk, however this time back along the track to see if I can find any late season orchids flowering. All I find are some Common mignonette orchids (Microtis media) growing on the very edge of the track. I check out burnt banksia scrub but nothing else is found.
Hood-like dorsal sepal
Protected from the elements under larger scrub
Up to 100 flowers per inflorescence

Remembrance day and we make a visit to Helms Arboretum to see if anything different is in flower out there. Only found some Common mignonette orchids and lots of the South African orchid (Disa bracteata) which is an introduced species that appears to occur in habitats that are disturbed or degraded from Geraldton to Israelite Bay during October and November. All the Sun orchids had finished for the season.
Flowers open all the way to the tip
Very distinct inflorescence

The final orchid hunt occurred on the drive back from Perth. Nearly 4pm in the afternoon we pull into our special place in the East Naernup Nature Reserve on Mills Road near Munglinup. This little patch of bush we search and the first find are more Common mignonette orchids, which seems to be the only thing left flowering. Whilst grabbing a photo of one of these orchids, something catches my eye. Finally something different is found late in the season. A very poor specimen of the Ravensthorpe rufous greenhood (Pterostylis leptochila) is found, which flowers late September to November in a restricted range, from Ballinup River to Munglinup.
Little hood formed by dorsal sepal
Green, olive or brown and white flowers
As it was just past 4pm and the sun was shining brightly we decide to spread out our search. This proved fortuitous as we discovered a much better rufous greenhood specimen as well as other mignonette orchids.
Curled lateral sepals
Cupped, narrow-ended lateral sepals
Rosette withered at time of flowering
Little visitor to one of the flowers
Standing up to 250mm in height
This did prove to be our last orchid hunt of the 2018 season.
Roll on March 2019 when the hunt commences for the 2019 season.
Deb arrives home after another overnight shift and seeing it is Sunday we decide to take a trip out to Coolinup Road so we can get a decent orchid hunt in before her next shift starts at 5pm.
We arrive at the little granite spot on Coolinup Road (Mud Map SE37/38), park the Triton and go exploring. In a field of Yellow flowering sundews (drosera) we find some bee orchids. Due to their small stature I will be naming these the Common bee orchid (Diuris decrementa) which flowers September and October in a large range from Gingin to Israelite Bay.
Yellow, brown marked flowers
Glowing in moist run-off from granite
Clump forming habit
Also hiding in the yellow carpet were some small Lemon-scented sun orchids (Thelymitra antennifera) which flower July thru October in a very large range from Kalbarri to Kalgoorlie to Israelite Bay including the whole South West corner.
Petals and sepals uniform size and shape
Growing in a bed of Drosera
What is it with yellow flowers today? Looking all alone is a small Cowslip orchid (Caladenia flava subsp. flava) which has the same large range and flowering period as the Lemon-scented sun orchid.
