What better reason to travel up to Perth and Dwellingup than to help to celebrate 2 milestone birthdays. This will be the first road trip in my new car, a hybrid Toyota Corolla I have named Fili, due to its red colouring matching the Blood spider orchid (Caladenia filifera).
Travelled up Friday by taking another RDO, which gives us time to make a quick orchid stop, firstly near Corrigin (Mud Map E12). Not a very successful location this early in the season with only 1 bunny orchid found. Given the location and the small stem leaf I will name this one the Blunt-leaved bunny orchid (Eriochilus dilatatus subsp. brevifolius), which flowers April to June over a range from Murchison River to Toolina Cove, as previous subspecies orientalis and undulatus have now been combined into brevifolius. Refer this BioOne article.
One other location checked quickly was Williams Road where we found a shell orchid in bud; most likely the Red-veined shell orchid (Pterostylis hamiltonii) which flowers late May to early August over an inland range from Toodyay to Stirling Range.
Now to get to Perth for the 60th Birthday Party for a High School and Youth Club friend, Kim.
Next morning, Saturday the 13th we head up to Dwellingup to catch up with my sister Lorraine and her family, who was celebrating her 70th birthday by having a weekend away. As the road bridge over the Murray River was closed for repairs we parked on the North bank and walked over and then onto Nanga Bush Camp where my sister and family were staying. After enjoying a wonderful Birthday breakfast, we said our goodbyes and got drenched on the walk back to our cars due to a freak rain shower. Welcome back to Dwellingup 🙂
Back in Dwellingup we pop up to the Forest Discovery Centre to say hello to Megan, my niece and it is in the carpark we find some bunny orchids. It was fun showing people these unusual small orchids for the first time. The orchids found are now known as the White bunny orchid (Eriochilus dilatatus subsp. dilatatus) as per the beforementioned article on BioOne. Subspecies magnus and multiflorus, which these orchids would have most likely have been identified as, have been absorbed by dilatatus.
We spend the afternoon with Geoff and Robyn and sister; Maxine which leads into an evening catch-up and sleepover. Next morning, we make the start of our long drive home to Esperance. Only one orchid hunt is completed on this leg and that is checking a location near Hyden for the elusive Winter spider orchid.
No luck with them but we did find some more bunny orchids. This time round they appear to be the now defunct Crinkle-leafed bunny orchid (Eriochilus dilatatus subsp. undulatus) which is now subsp. brevifolius as per the previously mentioned article.
It was a great weekend catching up with family and friends and being there to celebrate Kim’s 60th and Lorraine’s 70th birthdays. Orchid wise not so great, but we did find some.
IMPORTANT NOTE
It was only when writing this blog in Jan 2024 that I realized Florabase had removed the following subspecies from the dilatatus group: magnus, multiflorus, orientalis and undulatus. Only 2 subspecies remain: dilatatus and brevifolius.
I then checked online and found the BioOne article dated 16/04/2020, which advises which subspecies were combined. I have now named my orchids based on this change.
My latest reference book: The Complete Orchids of Western Australia (Andrew Brown) however still includes a total of 8 subspecies, which adds to confusion with Identification.
