The most prominent feature of the flower is its hood- or bonnet-shaped labellum which is long and wide, greenish to lilac-coloured with a network of purple or maroon veins and a few purple spots. The base of the labellum is narrow and surrounds the column. The sepals are green, and and the petals are and about wide, all spreading apart from each other. Flowering occurs from September to April.Les Robinson - Field Guide to the Native Plants of Sydney, page 244
