This recently discovered orchid is only known from a few locations near Boddington. It is similar to both the Cossack Spider Orchid and the Northern Darting Spider Orchid (Caladenia uliginosa subsp. candicans). Like both of those species, it is found in winter wet flats under Wandoo trees and flowers later (October) than other spider orchids in the area.
