Commonly known as the Hairy Rufous Greenhood (Pterostylis ciliata), this native orchid is endemic to the south-west of Western Australia region. Other common names include Tall Rusthood and Hairy Rustyhood.
This native orchid has a large rosette of between four and eight leaves at its base. The leaves are usually withered by flowering time, flowering occurs from September to November.
From the rosette are up to eight or more green, brown, white flowers with translucent panels between 15–20 mm long and 8–9 mm wide, borne on a flowering spike between 100–220 mm tall. The flower leans forward. The labellum is small, fleshy, insect-like and covered with hairs.
The specific epithet (ciliata) is derived from the Latin word cilium meaning “eyelash”, that refers to the hairs on the labellum.
