Genoplesium trifidum, commonly known as the trifid midge orchid,[1] is a small terrestrial orchid endemic to New South Wales. It has a single thin leaf fused to the flowering stem and up to twenty five dark purplish-black and green flowers. It grows in heath in scattered places in the Sydney basin.
Description
Genoplesium trifidum 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 twenty five dark purplish-black and green flowers are arranged along a flowering stem Шаблон:Convert long. The flowers lean downwards slightly and are Шаблон:Convert long and 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 Шаблон:Convert long and about Шаблон:Convert wide with hairless edges and darker coloured bands. The lateral sepals are about Шаблон:Convert long and about Шаблон:Convert wide, with a humped base and a sharply pointed tip. The petals are about Шаблон:Convert long and about Шаблон:Convert wide with hairless edges and a sharply pointed tip. The labellum is egg-shaped, about Шаблон:Convert long and Шаблон:Convert wide, thick and fleshy. There is a broad, tapering callus in the centre of the labellum and extending nearly to its tip. Flowering occurs from January to April.[1][2][3]
Taxonomy and naming
The blackish midge orchid was first formally described in 1941 by Herman Rupp who gave it the name Prasophyllum trifidum and published the description in The Victorian Naturalist. The specimen was collected near Castlecrag.[4][5] In 2022, Matthew Renner changed the name to Genoplesium trifidum[2][6] and the name is accepted by Plants of the World Online.[7] The specific epithet (trifidum) is a Latin word meaning "three-cleft",[8] referring to the shape of the column.[5]
Distribution and habitat
Genoplesium trifidum grows in heath or heathy forest between Kurri Kurri and Middle Harbour.[3]
