Pterostylis calceolus

Pterostylis calceolus, is a terrestrial, perennial, deciduous, herb with an underground tuber and a rosette of between four and six egg-shaped leaves, long and wide. Flowering plants have between two and seven reddish-brown flowers with transparent sections, each flower long, wide. The flowers are borne on a flowering spike tall with between two and four stem leaves wrapped around it. The dorsal sepal and petals form a hood or "galea" over the column with the dorsal sepal having a downturned, thread-like point long. The lateral sepals are long, wide, turn downwards and joined for about half their length. The lateral sepals are dished and suddenly narrow to thread-like tips long which curve forwards with hooked ends. The labellum is brown, fleshy, insect-like, about long, wide and egg-shaped with short bristles on the "head" end and eight to ten pairs of longer bristles on the "body". Flowering occurs from October to November. ==Taxonomy and naming==

Pterostylis calceolus was first formally described in 1989 by Mark Clements from a specimen collected in Bungonia Gorge and the description was published in Australian Orchid Research. The specific epithet (calceolus) refers to the outline of the labellum which resembles a slipper or shoe of the type worn in the middle-ages. ==Distribution and habitat==

Bungonia rustyhood is only known from the Bungonia district where it grows in forest and woodland. ==References==
