Description
Genoplesium pedersonii is a terrestrial, perennial, deciduous, herb with an underground tuber and a single thin leaf Шаблон:Convert long and fused to the flowering stem with the free part Шаблон:Convert long. Between five and thirty flowers are well spaced along a flowering stem Шаблон:Convert tall and taller than the leaf. The flowers lean downwards and are greenish red to reddish, about Шаблон:Convert wide. The flowers are inverted so that the labellum is above the column rather than below it. The dorsal sepal is broadly egg-shaped, about Шаблон:Convert long and wide and concave. The lateral sepals are lance-shaped, about Шаблон:Convert long and Шаблон:Convert wide and spread widely apart. The petals are egg-shaped, about Шаблон:Convert long and Шаблон:Convert wide. The labellum is dark purplish red, egg-shaped with the narrower end towards the base, about Шаблон:Convert long, Шаблон:Convert wide and turns upwards near its middle. There is a dark purplish black callus in the centre of the labellum and covering about two-thirds of its surface. Flowering occurs from December to April.[1][2]
Taxonomy and naming
Genoplesium pedersonii was first formally described in 1991 by David Jones and the description was published in Australian Orchid Research.[3] In 2002, David Jones and Mark Clements changed the name to Corunastylis pedersonii and the species is known by that name in Queensland, but the name is not accepted by the Australian Plant Census.[4][5] The specific epithet (pedersonii) honours Mr Ted Pederson who discovered this and several other orchid species.[2]
Distribution and habitat
Genoplesium pedersonii grows with sedges and mosses in moist areas on rock ledges on the Blackdown Tableland.[2]
There are unconfirmed records of this species from the Pilliga forest in New South Wales.[6]
