Genoplesium woollsii, commonly known as the dark midge-orchid, is a species of orchid endemic to New South Wales. It has a single thin, wiry leaf and in autumn has up to thirty five drooping, dark purple flowers on a flowering stem which is fused to the lower part of the leaf.

Description

Genoplesium woollsii is a terrestrial, perennial, deciduous, sympodial herb with a single cylindrical, glabrous leaf fused to the flowering stem.

Between five and thirty five dark purple flowers with darker streaks are arranged on a flowering stem Шаблон:Convert tall. The flowers droop forwards, and are about Шаблон:Convert long, Шаблон:Convert wide. 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, Шаблон:Convert long, Шаблон:Convert wide, sharply pointed and with short hairs on the edges. The lateral sepals are linear to lance-shaped, Шаблон:Convert long, Шаблон:Convert wide and diverge from each other. The petals are egg-shaped, Шаблон:Convert long, about Шаблон:Convert wide with a pointed tip and short hairs on the edges. The labellum is egg-shaped, Шаблон:Convert long, Шаблон:Convert wide with densely hairy edges and a sharply pointed tip. There is a callus in the centre of the labellum and along about three-quarters of its length. Flowering usually occurs between February and April.[1][2][3]

Taxonomy and naming

The dark midge orchid was first formally described in 1865 by Ferdinand von Mueller who gave it the name Prasophyllum woollsii and published the description in Fragmenta phytographiae Australiae''.[4][5] In 1989, David Jones and Mark Clements changed the name to Genoplesium woollsii.[6]

Distribution and habitat

The dark midge-orchid grows in heath, forest and moss gardens mainly between the Blue Mountains and Batemans Bay.[2]
