Short-lip leek-orchid (Prasophyllum brevilabre)
Description
Prasophyllum brevilabre is a terrestrial, perennial, deciduous, herb with an underground tuber and a single tube-shaped leaf up to 350 mm (10 in) long with the free part 20–80 mm (0.8–3 in) long. Up to thirty flowers are well-spaced along a flowering spike 150–500 mm (6–20 in) tall. The flowers are greenish-brown and as with others in the genus, the flowers are inverted so that the labellum is above the column rather than below it. The dorsal sepal is egg-shaped to lance-shaped, reddish-brown and 7–8 mm (0.28–0.31 in) long. The lateral sepals are about 10 mm (0.4 in) long, sometimes joined together but often free from each other. The petals are linear to lance-shaped, 8–10 mm (0.3–0.4 in) long, sometimes wavy and sometimes sickle-shaped. The labellum is spoon-shaped, 8–10 mm (0.3–0.4 in) long and about 3 mm (0.1 in) wide. It is turned back on itself so that its tip almost touches its base, and its edges are wavy. Flowering occurs from September to January, most prolifically after fire the previous summer.
