VRiv, Gold. Also Qld, NSW. Very rare in Victoria where known only from the Rushworth area in mallee and adjacent Box/Ironbark forest on stony or gravelly well-drained soils.
Easily recognised by the very long thread-like free points to the lateral sepals and the large basal appendage on the labellum.
