Prasophyllum parviflorum is a terrestrial, perennial, deciduous, herb with an underground tuber and a single tube-shaped 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. Between ten and thirty flowers are widely spaced along flowering stem Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). long which reaches to a height of Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value).. The flowers are greenish-brown to purplish and as with others in the genus, are inverted so that the labellum is above the column rather than below it. The ovary is oval-shaped and about Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). long. The dorsal sepal is a tapering egg shape, about 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 petals are Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). long, Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). wide and curve forwards. The labellum is variably coloured, about Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). long, Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). wide and sharply upwards near its middle. There is a broad, fleshy, glossy callus along the centre of the labellum and extending nearly to its tip. Flowering occurs in October and November.[2][3]
Taxonomy and naming
The slender leek orchid was first formally described in 1930 by Richard Sanders Rogers who gave it the name Prasophyllum hartii var. parviflorum and published the description in Transactions and Proceedings of the Royal Society of South Australia from a specimen collected on Wilsons Promontory.[4][5] In 1941, William Henry Nicholls raised the variety to species status.[1] The specific epithet (parviflorum) is derived from the Latin words parvus meaning "small"[6]:590 and florum meaning "flower".[6]:338
Distribution and habitat
Prasophyllum parviflorum grows in grassland and grassy areas in woodland east from French Island to the New South Wales border. Specimens collected in the west of the state may be P. suaveolens and small plants may, with further studies, be shown to be a separate species.[2][3][7]
Conservation
Prasophyllum parviflorum is listed as "Vulnerable" under the Victorian Flora and Fauna Guarantee Act 1988.[3]
