23/10/2022 ….. Ride out to Ridley (Mount)

Sunday Drive, Western Australian Orchids

Today is a much sunnier day than yesterday, so our drive north will be nice and warm. After around 1 hr in the Triton we arrive at Mount Ridley where we first venture up to the Rock Art. Here we show Lorraine, my sister and brother-in-law Ken the art hidden on the underside of the hollowed-out boulder. It is quite amazing.


We then go exploring the nearby boulders and other interesting rocky features. It is during this walk around that amazingly, we find an orchid growing in the very hot, dry foliage, in a shallow soil pocket on the granite. The orchid is from the Rufous complex of the Pterostylis genus. The rosette is completely dried as are three of the five flowers. Another similar specimen is found further along which also has a dried rosette and four of the seven flowers are finished. The 2nd specimen appears to match the description for the Striped rufous greenhood (Pterostylis zebrina) which is recorded as flowering in September and October over a range between Karlgarin and Mt Ridley, the latter being our current location.


We explored a bit more, enjoying the unique rock formations of the area and unexpectedly we came across some other orchids. Orchids from the Microtis genus were found growing with the “Borya” in shallow soil on the granite, with taller ones found growing in the scrub at the base of the rocks. As they had finished flowering it is not possible to positively identify them so will just leave them assigned to their genus.


Moving back to the carpark at the base of the rock, we enjoy a bite to eat for lunch at the old well site. Back on foot we walk around to the rock wave, for some quiet contemplation, before heading home for a coldie.
