Description
Genoplesium parvicallum is a terrestrial, perennial, deciduous, herb with an underground tuber and a single thin leaf Шаблон:Convert long with the free part Шаблон:Convert long. Between fifteen and twenty five greenish flowers with purplish brown stripes are arranged along a flowering stem Шаблон:Convert long and much taller than the leaf. The flowers are about Шаблон:Convert long, Шаблон:Convert wide and as with others in the genus, are inverted so that the labellum is above the column rather than below it. The dorsal sepal is Шаблон:Convert long, Шаблон:Convert wide with a sharply pointed tip and a few hairs on its edges. The lateral sepals are Шаблон:Convert long, Шаблон:Convert wide with a humped base and spread widely apart from each other. The petals are Шаблон:Convert long, Шаблон:Convert wide with a pointed tip and hairy edges. The labellum is about Шаблон:Convert long, Шаблон:Convert wide and purplish with a pointed tip and red hairs on its edges. The labellum quivers in the slightest breeze and there is a small, club-shaped callus in its centre. Flowering occurs between December and February.[1][2]
Taxonomy and naming
The mountain-top midge orchid was first formally described in 1945 by Herman Rupp who gave it the name Prasophyllum parvicallum from a specimen collected on Mount Greville and the description was published in The Queensland Naturalist.[3][2] In 2002, David Jones and Mark Clements changed its name to Corunastylis parvicalla and the species is known by that name in Queensland, but the change is not accepted by the Australian Plant Census.[4][5] The specific epithet (parvicallum) is derived from the Latin word parvus meaning "little"[6] referring to the small labellum callus of this orchid.[2]
Distribution and habitat
The mountain-top midge-orchid is only known from the summits of a few mountains in the McPherson Range where it grows in shallow soil over rock ledges with grasses and shrubs.[1]
