Top Orchids Found West of Esperance: A Field Report; Part IV

Day Trip, Western Australian Orchids

04/09/2024

Well, this has proven to be a full-on day trip looking for orchids. The last stop for the day is an East Munglinup location, though this time it’s on Jonegatup Road.

The first orchid found is the Small mantis orchid (Caladenia attingens subsp. gracillima), which has been a common orchid at various locations today.
Flowering occurs from August to October in woodlands and shrublands between Jerramungup and Israelite Bay.


Whilst capturing a photo of the Small mantis orchid, another smaller orchid is spied. Another better example is found soon after.
The Little frog greenhood (Pterostylis occulta) is found between Northampton and Ravensthorpe from late-August to October.
Our location is some 80kms to the east of Ravensthorpe, so a slight extension to its range.


Further along, a couple of specimens of the Zebra orchid (Caladenia cairnsiana) are found.
These small orchids occur between Lancelin and Esperance from August to early-November.


It was amazing to catch 2 species of orchids growing together. The Small mantis orchid was found under the watchful eye of the Common dragon orchid (Caladenia barbarossa).
The dragon orchid is found growing between Bindoon and Esperance from September to mid-November.


Appears to be the location for Caladenia species. Next up, we find the Short-sepaled spider orchid (Caladenia brevisura).
These orchids are found between Jerramungup and Israelite Bay during August and September.


5 other species were also spotted at this location.
4 were solo specimens:
Little laughing leek orchid (Prasophyllum gracile)
Sugar orchid (Ericksonella saccharata)
Western tiny blue orchid (Cyanicula aperta)
Common spider orchid (Caladenia varians)


Lastly was the Lemon-scented sun orchid (Thelymitra antennifera), which was found in a group, though not yet fully open.


So, our day trip finally comes to an end. We now need to drive the 112 kms home, but we do so with a sense of achievement.
This final location turned up 10 different orchid species, whilst over the whole day, we discovered at least 27 orchid species and at least 1 hybrid.
What a Day !!!!!

Top Orchids Found West of Esperance: A Field Report; Part II

Day Trip, Western Australian Orchids

04/09/2024

After a wonderful morning finding 15 species of orchids over numerous locations, we pull off the road to park up and enjoy lunch, from the boot of my small Toyota Corolla (Fili).
Neds Corner Rd is the border between the locations of Coomalbidgup and East Munglinup.
So, our lunch is in East Munglinup8, being West of the road however our explorations take us to the East side as well, which technically is in Coomalbidgup.
Not too confusing I trust. 🙂

After lunch we hit the surrounding area for another orchid hunt. Very close by we find our first orchids for the afternoon.
The Zebra orchid (Caladenia cairnsiana) is found growing between Lancelin and Esperance from August to early-November.


Red beaks (Pyrorchis nigricans) are usually found flowering the season after a summer fire has burnt its habitat. This is the case with this location, and they are found in great numbers.
Occur between Shark Bay and Israelite Bay from August to October.


Another orchid previously found today is also located at both sides of the road. The Small mantis orchid (Caladenia attingens subsp. gracillima) is found between Jerramungup and Israelite Bay during the period August to early-October.


A newbie for the day was next on the list. The tiny Little laughing leek orchid (Prasophyllum gracile) occurs between Shark Bay and Eyre during the period July to November.


An orchid which we always expect to find, but on occasions we are disappointed is the Cowslip orchid (Caladenia flava subsp. flava). Today we are not disappointed. In fact, we find hundreds growing on the banks of the Young River in the unburnt vegetation, whilst earlier we found sporadic ones growing in the bushfire zone.


In a bushfire regrowth area green with weeds and white sandy soil we find a great patch of the Esperance king spider orchid (Caladenia decora). These orchids range from Bremer Bay to Cape Arid from mis-August to October.


Another newbie and a surprise for the day is the Pink candy orchid (Caladenia hirta subsp. rosea) which occurs between Kalbarri and Israelite Bay from late-June to September.


Intermixed with the Cowslips was another yellow-coloured orchid. The Lemon-scented sun orchid (Thelymitra antennifera) is found between Shark and Israelite Bays from July to October.


As would be expected orchids found earlier today will also be found at this location being only 10km or so north. So further specimens of the Purple enamel orchid (Elythranthera brunonis) are found as they occur between Kalbarri and Israelite Bay from August to early-November.


A single king type spider orchid is found which does not appear to be the Esperance king spider orchid.
Due to the lack of red colouring and the drooping petals I will name this the Heberle’s spider orchid (Caladenia heberleana). These orchids are listed as occurring between Augusta and Cape Arid during September and October.
I have posted this ID on iNaturalist and will await other opinions.


Another solitary specimen is found, this time of the Pink fairies (Caladenia latifolia) which is found between Kalbarri and Israelite Bay from August to early-December.


Upon crossing the road, the first orchid found appears to be a hybrid. The parentage was hard to decipher until we found one of the parents close by.
I have decided the parents are Caladenia attingens x barbarossa.
Posted on iNaturalist for thoughts from others.


Just past the hybrid orchid we come across one of the parents. The Common dragon orchid (Caladenia barbarossa) is found scattered at the top of the ridge above the river flat.
These orchids are found between Bindoon and Esperance from September to mid-November.


Another orchid found as two separate specimens was the Beautiful donkey orchid (Diuris pulchella) which is listed as growing between Salmon Gums and Israelite Bay from July to September. The specimens were north and south of the river.
Our location is some 50km southwest of Salmon Gums but the species is recorded at this location in the Atlas of Living Australia.


As I was taking photos of orchids found Debbie is exploring further afield and she yells out excitedly.
She has come across a vast warren of the Rabbit orchid (Leptoceras menziesii) which has flowered due to the previous summer bushfire that scorched this area.
These orchids are found growing between Northampton and Israelite Bay from September to early-November.


Close by we also found the Esperance white spider orchid (Caladenia longicauda subsp. crassa) which occurs between Bremer and Israelite Bays from August to early-October.
Some may be the related Rigid white spider orchid (Caladenia longicauda subsp. rigidula) which occurs between Ravensthorpe and Israelite Bay during a similar flowering season.
The differences between the 2 species are the size of the flower and the rigidness or pendulousness of the petals and sepals.
Let me know your thoughts.


Crossing back over the river we come across more spider orchids that appear to be further Esperance king spider orchids.
However the better find was some other species of Donkey orchid. Due to the location and date found, I will be naming these the Green Range donkey orchid (Diuris littoralis) which is recorded as occurring between Denmark and Esperance from July to early-September.


Finally made it back to Fili at around 2pm and move onto another location.
16 species found at this location.
Part III to follow… Stay tuned

Numerous days, Road Trip, Western Australian Orchids

After not too cold a night we awake to a beautiful day in the Ongerup Gardens Caravan Park. After cereal for breakfast, we decide to go exploring the woodlands behind the caravan park. We take what we believe to be a rough track, but it peters out soon enough, so we go bush bashing in an attempt to find it again. We end up curving north and head up past the sporting complex. We cross Jaekel Steet and follow the track/s to the Yongergnow Malleefowl Centre, where we grab a coffee, for the walk back to the caravan park. The orchid count for such a good walk was a bit disappointing, however we did find some, so I will record them now.

07/10/2022 ….. Lake Toolbrunup & Kebaringup

Anderson Lake NR, Nature Reserves, Numerous days, Road Trip, Western Australian Orchids

Next stop on our winding drive back to Esperance is another new location. Anderson Lake Nature Reserve which is 30kms east as the crow flies from Pootenup Nature Reserve, will hopefully produce some different orchids. As we get close to the location it is apparent that it is much drier so let’s see if we actually find anything at all.

As anticipated, we struggled to find any orchids, however the ones found were indeed different. Very close to where we park, we find our first orchid. The Purple veined spider orchid (Caladenia doutchiae) flowers August through October, between Mullewa and Ravensthorpe. References checked indicate it is found growing on rises around salt lakes, which is exactly the habitat we are currently searching. Four sperate flowers were located, which portray the variable colouring to this species.


It was another 15mins or so before we stumbled across another orchid. This time it was the Midget greenhood (Pterostylis mutica) that caught Debs eye. The lime green colouring stands out against the otherwise brown foliage. These small orchids flower July through October, between Wongan Hills and the SA border. They are also found in QLD, NSW, Vic, Tas and SA. Florabase mentions they are known to grow around saline lakes, again confirming we are in suitable habitat.


The next orchid found was a pleasant surprise. First up we thought it was a frog greenhood, but as we settled in to take some photos it became apparent that it was another species. After getting back into the Triton we are excited to note that this is a new species for us. The Ruddy hood (Pterostylis perculta) flowers from late September to early November between Kojonup and Cape Arid National Park. It was only formally named in 2015, previously called sp. “Ongerup’ which alludes to its location. It is a small orchid growing to 150mm in height, may have up to 5 flowers per orchid and is found growing in sandy-clay and clay soils.


As alluded to earlier we had returned to the Triton as this location did not prove overly productive, however finding a new species is always amazing. We head north up to Gnowangerup, then west stopping along the roadside in Kebaringup. I believe this is only our 2nd time visiting this location so we will see what turns up this time.

Straight up the large white spider orchids catch our eye. The Stark white spider orchid (Caladenia longicauda subsp. eminens) is probably the species found, based solely on location. They flower August to early October between Moora and Esperance and can grow to 600mm in height.


Further orchids are found, though not in great numbers. The Little laughing leek orchid (Prasophyllum gracile) the Cowslip orchid (Caladenia flava subsp. flava) and the Green spider orchid (Caladenia falcata) are all represented by sole specimens.


More Purple veined spider orchids are found in better numbers. Then another single specimen on anorchid is found. The Common mignonette orchid (Microtis media subsp. media) is a widespread orchid being found flowering between Shark Bay and Eyre during the months of September through January. The final orchid found for the day was a good bunch of Jospeh’s spider orchid (Caladenia polychroma), which are found between Boyup Brook and the Fitzgerald River National Park during the months of September and October.


We decide to move on and look for somewhere to stay the night. As we have 2 vehicles and a camper trailer, we make the decision to check into the Ongerup Gardens Caravan Park for the night. It was a choose you own site sort of place, so we parked up close to the ablutions. This was a great day orchid hunting in our wonderful Western Australian outdoors.
