Bunochilus umbrinus D.L.Jones Pterostylis umbrina, commonly known as the broad-sepaled leafy greenhood, is a plant in the orchid family Orchidaceae and is endemic to the Australian Capital Territory and New South Wales on the Southern Tablelands.

The dorsal sepal and petals are joined to form a hood called the "galea" over the column.

[2] The broad-sepaled leafy greenhood was first formally described in 2006 by David Jones and Mark Clements and given the name Bunochilus umbrinus.

[4] The specific epithet (umbrina) is a Latin word meaning "dull brown", referring to the colour of the labellum compared to P.

[2] Pterostylis umbrina occurs on Black Mountain in the Australian Capital Territory and in disjunct populations in New South Wales between Burrinjuck and Tumut.
