Description

Genoplesium psammophilum 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 five flowers are crowded along a flowering stem which is Шаблон:Convert long, reaching to a height of Шаблон:Convert. The flowers are dark red or brownish red and about 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 linear to egg-shaped, about Шаблон:Convert long and Шаблон:Convert wide and the lateral sepals are more or less lance-shaped, about Шаблон:Convert long, Шаблон:Convert wide and spread widely apart. There is a small, white gland on the tip of the lateral sepals. The petals are linear to egg-shaped, about Шаблон:Convert long and Шаблон:Convert wide with an s-shaped gland on the tip. The labellum is light to dark red, elliptic to egg-shaped with the narrower end towards the base, about Шаблон:Convert long and Шаблон:Convert wide. There is a reddish to reddish black callus in the centre of the labellum and covering about half of its surface. Flowering occurs from March to May.

Taxonomy and naming

Genoplesium psammophilum was first formally described in 1991 by David Jones from a specimen collected near Amity and the description was published in Australian Orchid Research. In 2002, David Jones and Mark Clements changed the name to Corunastylis psammophila and the species is known by that name in Queensland, but the name is not accepted by the Australian Plant Census. The specific epithet (psammophila) is derived from the Ancient Greek words ψάμμος (psámmos), meaning “sand”Шаблон:Rp and φίλος (phílos), meaning “dear one" or "friend”,Шаблон:Rp referring to the soil type in which this species is found.

Distribution and habitat

Genoplesium psammophilum grows in coastal and near-coastal heath and wallum in south-eastern Queensland.
