So have a guess where I went on the first official orchid hunt for the 2020 season? If you guessed Mud Map Ref: SE35 you are correct. Helms Arboretum is our so called “Rabbits foot” location and I was not let down entirely. Nothing in flower however White bunny orchids were in bud.
However only 3 days later they had bloomed. Deb was with me today, so we both got to see the first orchids in flower for the season. White bunny orchid (Eriochilus dilatatus subsp.dilatatus) is found from Dirk Hartog Island to Israelite Bay. Flowering period is March to May so it is one of the first orchids to flower in WA.
First up we checked out Helms Arboretum (Mud Map SE35) where we were excited to find the Leafless orchid (Praecoxanthus aphyllus). This orchid is the sole species in the genus and is endemic to Western Australia, where it is found between Pinjarra and Esperance during the months of March, April and May.
Leafless orchids may grow to 400mm in height
We then move further north and find some Pygmy orchids (Corunastylis fuscoviridis) in the Redlake townsite Nature Reserve. This orchid was originally named in 1883 and placed in the Prasophyllum genus however in 2002 it was moved to the Corunastylis genus. Then in 2018 it was re-named C. fuscoviridis as it was formally named C.tepperi, which is a species found in Victoria and South Australia. This is the sole West Australian species and is located from Corrigin to Eyre. It is also found in South Australia and Victoria, hence the naming issues.
Pygmy orchids may grow to 250mm in height but they are very difficult to spot in the leaf litter.
March proved to be the month when the Orchid season began in my local area. Four species are recorded as flowering during March around the Esperance area. We were lucky enough to find three of the four, with the Hare orchid the being the elusive species.
