Pterostylis barringtonensis

Pterostylis barringtonensis, is a terrestrial, perennial, deciduous, herb with an underground tuber. Non-flowering plants have a rosette of between three and six leaves, each leaf long and wide on a stalk high. Flowering plants lack a rosette but have up to seven flowers on a flowering spike high with between five and seven linear stem leaves which are long and wide. The flowers are long, wide. The dorsal sepal and petals are joined to form a hood called the "galea" over the column. The galea is dark green with darker green lines and a brown, tapered tip. The lateral sepals turn downwards and are long, wide and joined for about half their length. The labellum is long, about wide and brown with a dark stripe along its mid-line. Flowering occurs from June to August. ==Taxonomy and naming==

Barrington greenhood was first formally described in 2006 by David Jones who gave it the name Bunochilus barringtonensis. The description was published in Australian Orchid Research from a specimen collected in the Barrington Tops National Park. In 2010, Gary Backhouse changed the name to Pterostylis barringtonensis. The specific epithet (barringtonensis) refers to the area where this greenhood grows with the Latin suffix -ensis meaning "place for" or "where", referring to Barrington Tops. ==Distribution and habitat==

Pterostylis barringtonensis occurs in moist places in tall forest in the Barrington Tops area. ==References==
