29/07/2020 ….. Dempster Head and Myrup

Dempster Head, Esperance, Myrup, Western Australian orchids

On my planned RDO I revisit Dempster Head (Mud Map SE 34), this time in the company of my dearest Deb, who only has the morning free, due to her night shift roster. We head off in the direction of the helmet orchids and like my last visit the snail orchids are first orchids found. ID again up in the air.

Then Deb finally gets to see the little Crystal helmet orchids (Corybas limpidus) in flower at Dempster Head. We visit two of my three known locations and capture some more photos of theses small orchids.

Also found were Mosquito orchids (Cyrtostylis robusta) in various locations along the track. I used a nearby rock once to assist with focusing, as the overcast day made focusing on these small orchids rather difficult.

Deb then finds some shell orchids in flower… So Happy as it has been a few years since we last found them on Dempster Head. The Curled-tongue shell orchid (Pterostylis rogerii) is a southern coastal shell orchid found between Binningup and Esperance. The rosettes of unflowering orchids are commonly found with only a few orchids flowering usually located. Oddly enough flowering shell orchids lack that same rosette.

A small patch of yellow catches our eye and we are rewarded with finding the Spectacled donkey orchid (Diuris conspicillata) which is geographically restricted to coastal granite outcrops near Esperance. The dark markings on the labellum lateral lobes are said to give the orchid the impression it is wearing spectacles.

After nearly 2 hours searching for orchids it time to head home so Deb can have a rest before her shift starts at 2pm.

To get the most out of my RDO, after Deb heads off to work, I decide to go check out another location close to town. We refer to this spot as our Myrup location. Parking up just after 3pm I am shocked to find that someone had decided to dump a large amount of household rubbish in the bush, rather than pay at the Shire refuse site. Some people make you shake your head in their total disrespect for the environment. To add to this horror the Shire has also graded the road verges and widened the road so a lot of gravel and destroyed vegetation has just been pushed onto the vegetated verge.

It is right on the edge of this devastation that I come across some beautiful Esperance king spider orchids (Caladenia decora) flowering in various colours. Some may actually be hybrids with the Esperance white spider orchids or similar.

Across the road I come across many more in flower, with more still to come, given they are recorded as flowering from mid-August to October.

In the middle of these large bright king orchids I come across some small white spider orchids. The Common spider orchid (Caladenia varians) is a widespread orchid occurring between Kalbarri and Esperance. These little guys were definitely dwarfed by the large Esperance king spider orchids.

A successful RDO spent searching for orchids now comes to an end. Work tomorrow 😦

Orchids grow in amazing places

Dempster Head, Esperance, Western Australian orchids

Amazed to find these snail orchids (Pterostylis sp.) growing in the small amount of rubble on a granite boulder over 2 metres above the surrounding ground. The 1st photo below is of the boulder. The 2nd photo is zoomed in with Circle indicating position of orchids contained in video 1 and the Arrow indicates location of the 4 orchids in video 2. The 4 orchids are also the Feature Image of this post.

26/07/2020 ….. Boyatup Bound & Beyond

Cape Arid NP, Day Trip, National Parks, Western Australian orchids

Deb arrives home from her night shift and will spend a quiet day at home, however I am taking a friend, another Deb, out East to see what our favourite locations will produce in mid Winter.

Boyatup Hill (Mud Map SE 40) is our first destination for the day. As usual we stop along the track prior to reaching the gravel pit and immediately find some spider orchids in flower. They appear to be the Common spider orchid (Caladenia varians) due to the larger labellum and less pendulous petals and sepals.

Then to confuse matters a couple of what appears to be the Western wispy spider orchid (Caladenia microchila) are located. The thinner labellum and more pendulous sepals and petals alludes to this identification.

Next up a colourful Esperance king spider orchid (Caladenia decora) is located growing near a mound of dirt pushed up in making the gravel pit. They are one of the largest spider orchids found in Western Australia.

Another regular found out this way is the Blue beard (Pheladenia deformis) which is also commonly known as the Blue fairy orchid. The genus Pheladenia is monotypic as it contains only the one species. They come in various shades of blue and purple plus there is a white variety, which is very rare to locate.

Around the edge of the gravel pit in a damp location more spider orchids are found, of varying types and colourings.

Then growing in patches of vegetation in the gravel pit itself, donkey orchids are found in flower. Due to the colouring of the orchids found I believe them to be Green Range donkey orchids (Diuris littoralis) as they are one of only a few Diuris orchids flowering this far east.

Moving up to the track leading from the gravel pit we find the bright and colourful Reaching spider orchid (Caladenia arrecta), which is the only clubbed spider orchid found this far east. Up-swept petals are also a distinctive feature.

Moving into the burnt area, from last summer’s bush fire, we come across a couple of donkey orchids and a Blue beard.

Further along the track just past the area we used to drive up to and turn around I find some small Mosquito orchids (Cyrtostylis robusta) growing alongside the track. The large dark labellum distinguishes this orchid as Mosquito and not the related Midge.

As we plan to visit a few more locations today we make tracks back to the Triton and along the way find some clumped Blue beards and a poor Esperance king spider orchid with all his tepals nipped off.

We now move onto Thomas River in the Cape Arid National Park. After a spot of lunch at the campgrounds we head to Len Otte Nature Trail and locate some Mosquito orchids growing under the shrubs on the granite incline, which is a first for me.

As we had found no other orchids by this part of the trail I decide to head back to the Triton and move on to another location, Alexander Bay. Snail orchids are found under shrubs growing on the coastal granite. Again I will not attempt to name these. One has very short lateral sepals however they may have been nipped off or are actually that short.

I contact Deb on the phone and she directs me to area where she had found the Esperance king spider orchids. This was great as I missed these on my last visit to this spot.

The afternoon is moving along quickly so time to head off for the last planned stop. At the top of Condingup Peak (Mud Map SE 39) I park the Triton then show Deb the granite lookout where snail orchids are usually found. However first up at the edge of the track I locate a Beautiful donkey orchid (Diuris pulchella) which is very distinctive due to its mauve colouring, which is unique this far East.

Also found along the track edge were some snail orchids. They appear to be Brittle snail orchids (Pterostylis timothyi) due to the fawn colouring of the flower and length of lateral sepals. They are also found growing on the granite lookout, however in much lower numbers than found in previous years.

Moving along the ridge of the Telstra installation a small white spider orchid is found. Appears to be a beautiful specimen of the Common spider orchid.

In the moss growing on the flat granite outcrops of the ridge many snail orchids are found. They are much shorter in stature, however still have longish lateral sepals and a rosette with pointed veiny leaves, so may still be Brittle snail orchids. I will leave the identification for now.

It’s 5pm so light is running out fast and taking photos is getting more difficult so we climb back up to the Triton and head back to Esperance. A great day out and about hunting down orchids and sharing the day with our friend Deb C.

25/07/2020 ….. Winter Afternoon Wander

Dempster Head, Esperance, Western Australian orchids

After Deb heads of to her Saturday night shift I decide to go check out Dempster Head Reserve and see if I can finally locate the helmet orchids others have mentioned growing there. We had previously found leaves which we were unsure if they were Corybas or Cyrtostylis orchids. It will be great to answer the mystery.

Parking up at the Rotary Lookout, I walk off in the direction of the port as that is where we have found the mysterious leaves. First up though I am distracted by the many snail orchids popping up in the usual, plus very unusual, locations. Unsure of the exact species however finding some growing on the top of a boulder was a unique find.

In the known patch of mysterious leaves I am lucky enough to find a couple in flower to answer the question of what species they belong to. The Crystal helmet orchid (Corybas limpidus) is confirmed as that species. These are found flowering from July till early-September over south coastal locations between Walpole and Esperance. The Latin name limpidus alludes to the transparent dorsal sepal and lateral sepals which form the helmet. Further around the trail I locate flowering corybas orchids in another two locations, so I am a very happy man.

Final orchid found for the afternoon was the Mosquito orchid (Cyrtostylis robusta) which was located right alongside the walking track. A widespread orchid found between Perth and Israelite Bay during the winter months.

Moving to the West Beach side of the reserve the orchids become few and far between and as it is now after 4:30pm I take an photo overlooking a pool of water with views in the background of West Beach. A calming shot to end an enjoyable few hours on a winters’ Saturday afternoon.

22/07/2020 ….. Deb’s Day Out with L&K

Cape Arid NP, Day Trip, National Parks, Western Australian orchids

Its back to work for me, however Deb decides to take Lorraine and Ken out further east for the day. The trip takes them out to Thomas River in the Cape Arid National Park. From here they travelled back west to Alexander Bay located at Howick in the Shire of Esperance.

Deb finds and takes photos of a few orchids at Alexander Bay just to rub it in that I was not there… LOL




<<<<<<< Brittle snail orchids (Pterostylis timothyi) with their distinctive veined pointed rosette leaves. Fawn colouring is also a feature.

Looks like they had a great day with beautiful sunny skies. Soooo jealous.

20/07/2020 ….. R.D.O. Ramble to Ravensthorpe

Cocanarup Timber Reserve, Day Trip, Esperance, National Parks, Nature Reserves, Pink Lake, Springdale NR, Stokes NP, Western Australian orchids

I have taken an Rostered Day Off (RDO) today so I can spend some more time with my sister Lorraine and her hubby Ken. Yesterday we went north of the South Coast Hwy and detoured back east of Esperance. Today we are going west and staying within 50kms of the coast.

Our first point of call is along the edge of our famous Pink Lake. Here we discover some Mosquito orchids (Cyrtostylis robusta) growing in the dense undergrowth. These unusual orchids flower during the winter months over an area stretching from Perth to Israelite Bay.

Nothing more found other than Pterostylis rosettes, with some in bud, so we move onwards. Next stop is the Stokes National Park camping grounds. Actually we find orchids before the campground, just growing along the roadside. First up are some wispy type spider orchids. Due to the colouring of the flowers and the larger leaf width, I believe these orchids to be the Common spider orchid (Caladenia varians). As the name suggests it is a common orchid with a large distribution, Kalbarri to Cape Arid National Park. It also has a long season, flowering from July to mid-October.

Intermixed with the spider orchids were patches of yellow. Bright yellow South coast donkey orchids (Diuris sp. ‘south coast’) are found from Denmark to Munglinup during the winter months. They were first recognised as distinct in 1999 when collected near Munglinup, which is approximately 20kms to the west of our current location.

We finally make it to the campground and it was a let down with only a Dark Banded greenhood (Pterostylis sanguinea) in flower and a Banded greenhood (Pterostylis vittata) finished for it’s season. We did however stop and have morning tea overlooking the Stokes Inlet.

We move on further west along the South Coast Hwy, before turning south down Springdale Road. We pullover to the side of the road at Springdale Nature Reserve for a quick check. Straight away we find the Reaching spider orchid (Caladenia arrecta) which blooms from late-July till mid-October between Bindoon and Esperance. Prominently clubbed petals and sepals ,plus the dark red labellum with dark red calli are distinctive features.

Also found were the South coast donkey orchids, with many more to come. However we must push on as it is now past lunch time and we still have Munglinup Beach campground to check out.

Well first up we drive down to the Oldfield River and park up on the granite rock bank, so we can have a quick scout around. Other than one South coast donkey orchid and many leaves in bud, nothing much was found so we quickly move on.

We now venture down to the Munglinup Beach campground (Mud Map SE 33) and I go looking for the elusive helmet orchid, whilst Deb takes Lorraine and Ken down to the beach. I come across loads of leaves and then find some sprouting flowers, however they are not fully open. By this time Deb has made her way into the Agonis flexuosa grove and we both simultaneously find fully open ones in different patches. They are confirmed as being the Crystal helmet orchid (Corybas limpidus) which flowers from July to early-September in coastal locations between Walpole and Esperance. We had to lie flat on the ground to get the photos as they are only 20mm in height.

Very happy to have found these beautiful small orchids flowering as they are listed for the Mud Map reference. Also found underneath the Agonis flexuosa trees are snail orchids. They appear to be the Coastal snail orchid (Pterostylis sp. ‘coastal snail’) which is found between Bremer Bay and Israelite Bay during the months of July and August. Distinctive features are bloated appearance and small thickened lateral sepals.

Leaving Munglinup Beach we now drive west towards Hopetoun our planned lunch stop. On the way we check out both Starvation Bay and Masons Bay campgrounds. Choosing the bakery for lunch we walk down to the foreshore and finally fill our bellies.

We now head north to Ravensthorpe where we grabbed a ginger ice-cream from Yummylicious Candy Shack. Sooooo good!! After showing Lorraine and Ken the Grain Silo’s, we head west out to Kukenarup Memorial, one of our regular orchid haunts.

Just past the Eagle Wings to the left is a wonderful little Dancing spider orchid (Caladenia discoidea) which is found between Israelite Bay and Kalbarri flowering during August, September and October.

Next up we find the Blue beard (Pheladenia deformis) which flowers over along season, May till October. They can occupy many different habitats, (woodlands, shrublands, granite outcrops and forests) over a range from Israelite Bay to the Murchison River. Many specimens are found at this location today.

On the return leg of the trail we find some donkey orchids. As mentioned in the Esperance Wildflowers blog (refer links) the Green Range and South coast donkey orchids overlap in their distribution and have very similar features which makes identifying them so much harder. I will call those found today South coast donkey orchids as the labellum mid lobe has light patches on the edges. However I am open to correction.

Final orchid for the day was the reliable Jug orchid (Pterostylis recurva) which occurs between Geraldton and Israelite Bay from August to October. As it is now past 5pm the light is fading fast, so the pics are not the best, however they still record the finding.

From here it is a quick dash to the lookout on Mt Desmond, east of Ravensthorpe, to catch the sunset. Another wonderful day showing Lorraine and Ken our beautiful SE coast and surrounds.

19/07/2020 ….. Cascade Calling

Cascade NR, Day Trip, Western Australian orchids

My sister, Lorraine and her hubby Ken are visiting us for a few days, so today we head out west to Cascade Falls. We are joined by our son Jace and his little family. The water is flowing nicely now it’s mid winter. The grandkids enjoy playing with all the foam caused by the water cascading over the granite rocks. After exploring the shore we set up on a flat area for a picnic lunch.

The little family head home whilst us oldies head off further west on an orchid hunt. This is a first for Lorraine and Ken, so let’s hope we have a successful hunt. We visit Cascade Nature Reserve and go for a check in the scrub/woodlands. With luck I come across some Dwarf shell orchids (Pterostylis brevichila), which we had found here previously. Not as many but still very happy to find them again. Dwarf shell orchids flower during the months of July, August and September over inland areas between Hyden and Mt Ragged.

As the image above shows we also find the Midget greenhood (Pterostylis mutica) which flowers from July till October over a much larger range, Wongan Hills to the South Australian Border. If fact they are also found in all the states of Australia. Another larger specimen was found further into our hunt.

Not much else turning up so we decide to head back to the Triton and stumble across one nice Banded greenhood (Pterostylis vittata) growing on the edge of the utilities track we are following.

Leaving Cascade Nature Reserve we head back east and stop along Boydell Road. In the road side scrub we locate some donkey orchids. They appear to be the Green Range donkey orchid (Diuris littoralis) which occurs in coastal and near coastal locations between Denmark and Esperance. They flower from July to early September and were only formally named in 2016 from specimens collected in 1995.

Not much else found so we head across the Coolgardie – Esperance Hwy and head into Neridup. Here we visit our favourite blue metal dump site and as we arrive I jump out to walk along the track in to see what I can find. The others drive in ,park up and get out stuff for afternoon tea. I discover some Brittle snail orchids (Pterostylis timothyi) growing in the gravelly mounds pushed up to create the blue metal dump. These awesome little orchids flower from July to September over an eastern range of Lake Cronin to Esperance. The prominently veined , pointed leaves of the rosette is a distinctive feature of these orchids.

Also on the edge of the cleared area in a slight depression, the spider orchids we found last year were again located. The Western wispy spider orchid (Caladenia microchila) flowers from July to early October and has an eastern distribution from Kondinin to Madura.

After enjoying afternoon tea we spread out and immediately find some more donkey orchids. They appear to be more Green Range donkey orchids, as the only similarly coloured donkey orchid found this far east is the Yellow granite donkey orchid. However we are not near any granite.

We now cross over Wittenoom Road and come across some Green-veined shell orchids (Pterostylis scabra) near a small, currently dry, road run-off trench. These orchids flower from May to August over a large mostly inland area from Kalbarri to Esperance. Unlike the Dwarf shell orchid found at Cascade this shell orchid has it’s labellum visible. A little like poking out their tongues.

Getting late in the afternoon and the sun sets early in winter, so we start to make our way back to the Trition. Along the way we find another colourful Donkey orchid, some more Brittle snail orchids and a small speck of blue. Blue beards (Pheladenia deformis) in bud but not yet open are found. So as the season moves on, so must we as we have a date around the fire pit at home will all our travelling companions from today.

A great family picnic followed by a successful orchid hunt. Not too bad for a Sunday in mid winter.

12/07/2020 ….. Helms in July

Esperance, Helms Arboretum, Western Australian orchids

What better way to spend an hour or so on a Sunday that to check out Helms Arboretum (Mud Map SE 35) for any orchids that may be flowering. Before the search though we stock up on energy by having a cooked breakfast at the Esperance Bird and Animal Park.

The first orchid found was the ever reliable Banded Greenhood (Pterostylis vittata) which occurs over a lengthy period (April to Sept) over a wide distribution (Perth to Balladonia). Fairly coastal east of Albany, whilst further inland it is replaced by either the Dark Banded Greenhood or recently named Mallee Banded Greenhood. In fact the distributions of these orchids overlap in places, as confirmed by finding a small Mallee Banded Greenhood (Pterostylis arbuscula) at Helms. These orchids are recorded as growing between Northampton and Eyre during the season June to September, over mainly inland locations.

Moving on to another section of the Arboretum we come across Snail orchids in varying stages of flowering. Naming Snail orchids is always difficult especially when some found in previous years at Helms have remained un-named. The pictures below I feel are of two different species. One is the common Hairy-stemmed snail orchid (Pterostylis setulosa) which flowers from June to September over a large range between Kalbarri and Balladonia. The other smaller snail orchid has, shorter lateral sepals, only 2 stem leaves, a rosette of quite rounded leaves plus does not have a hairy stem. It will remain un-named again this year.

Well not much happening at Helms this time. I trust we will visit again sometime this season and I look forward to a greater variety of orchids. Until next time!!!

11/07/2020 ….. Quick check at Dempster Head

Dempster Head, Esperance

Time to visit one of our regular haunts. Dempster Head, sometimes referred to as Rotary Lookout, which is an Esperance Shire Reserve that aims to protect a granite headland. As you can imagine the views from the lookout provide a 360 degree view of the Esperance town, bay and beaches.

We however check out some of the areas off the beaten track, so to speak, and are usually rewarded with orchids. Today proves no exception. We head to where we have found Corybas leaves in previous years. We hope they are flowering as their recorded season is July to early September. We find the leaves as expected and they are in bud, which is exciting, however none in flower were found. A return visit later in the season will be required.

Next up we head back to the walk trail as we have previously found Mosquito orchids. It appears we may be too early for these as well, due to the first location only having orchids in bud as well. However at another spot on the track we find a lone orchid in flower, with 2 flowers fully developed. Mosquito orchids (Cyrtostylis robusta) flower June to August in locations between Perth and Israelite Bay and can have up to 8 flowers per orchid.

Further around the track we come across a Banded Greenhood (Pterostylis vittata) with numerous flowers. These are common orchids found from Perth to Balladonia, which flower from April to September. Also found are some Snail orchids which have yet to fully form so I will not attempt to name them at this stage.

Not a lot flowering yet, so we will need to return at a later date to see if we are more successful. Until next time !!
