Description
Plants in the genus Habenaria are mainly terrestrial plants with fleshy tubers and upright, tall, thin or fleshy stems. The leaves are either arranged in a rosette at the base of the plants or scattered up the stem. The flowers are resupinate, usually small, white, green or yellowish and arranged along a tall flowering stem. The dorsal sepal and petals overlap to form a hood over the column. The labellum has a spur and usually three lobes which may be short or long and threadlike. The distinguishing feature of the genus is the presence of two club-shaped projections on the stigma.[2][4][5]
Taxonomy and naming
The genus Habenaria was first formally described in 1805 by Carl Ludwig Willdenow and the description was published in Species Plantarum.[1][6] The generic name is derived from the Latin word habena meaning "thong", "strap" or "rein".[7]
