Lua error in Module:Taxonbar/candidate at line 22: attempt to index field 'wikibase' (a nil value). Pterostylis diminuta is a plant in the orchid family Orchidaceae and is endemic to Victoria. As with similar greenhoods, the flowering plants differ from those which are not flowering. The non-flowering plants have a rosette of leaves flat on the ground but the flowering plants have up to twelve small, partly green, partly translucent flowers and lack a rosette.

Description
Pterostylis diminuta, is a terrestrial, perennial, deciduous, herb with an underground tuber. Non-flowering plants have a rosette of between three and six, egg-shaped leaves, each leaf Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). long and Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). wide. Flowering plants lack a rosette but have up to twelve flowers on a flowering spike Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). high with four to seven linear to lance-shaped stem leaves which are Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). long and Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). wide.

The dorsal sepal and petals are joined to form a hood called the "galea" over the column. The galea is dark green with translucent "windows" and a brownish, tapered tip.

Taxonomy and naming
The small-flowered leafy greenhood was first formally described in 2006 by David Jones and Mark Clements and given the name Bunochilus diminutus. The description was published in Australian Orchid Research from a specimen collected in the Deep Lead Reserve near Stawell.[4] In 2007, Gary Backhouse changed the name to Pterostylis diminuta.[1] The specific epithet (diminuta) is derived from the Late Latin word diminutivus meaning "tiny".[5]
Distribution and habitat
Pterostylis diminuta occurs in grassy or shrubby woodland and forest between Ballarat and the Grampians in Victoria.[2][3]
