Caladenia anthracina is a terrestrial, perennial, deciduous, herb with an underground tuber surrounded by a fibrous covering. A single hairy, dull green, lance-shaped leaf, Шаблон:Convert long and Шаблон:Convert wide appears above ground in May or June, following rain.[1][2]

A single flower, Шаблон:Convert in diameter is borne on a densely spike Шаблон:Convert high. The dorsal sepal is erect, linear to oblong, Шаблон:Convert long, Шаблон:Convert wide and tapers near the end to a thick, black tip. The lateral sepals are lance-shaped, Шаблон:Convert long, Шаблон:Convert wide and taper towards a black tip similar to the one on the dorsal sepal. The petals are Шаблон:Convert long, Шаблон:Convert wide and also taper to a black point. The labellum is a broadly egg-shaped when flattened and curves forward, Шаблон:Convert long and Шаблон:Convert wide and is strongly curved towards the tip. It is white to cream-coloured and there are four to six rows of dark reddish-purple calli along in the centre part and short, blunt teeth along the edge. The column is Шаблон:Convert long and translucent with reddish markings and narrow wings. Flowering occurs between late September and early November.[2][1]

Taxonomy and naming

The species was first formally described by David L.

Distribution and habitat

Caladenia anthracina is only known from an area of Шаблон:Convert in the Midlands where it grows in grassy woodland in sandy soil.[1]

Conservation

This species is classified as "Endangered" by the Tasmanian Government and is listed as "critically endangered" (CR) under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).[1]
