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.
