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.
