They are terrestrial herbs with a creeping rhizome, an upright flowering stem and dark coloured leaves with contrasting veins. The flowers are relatively large and have a large labellum, markedly different from the sepals and petals.

Description

Orchids in the genus Anoectochilus are terrestrial, perennial, deciduous, sympodial herbs with a creeping, above-ground rhizome with wiry roots that look woolly. The leaves are arranged in a rosette and are relatively broad and thin. They are dark green or brownish purple and have a contrasting network of silvery or reddish veins. The flowers are relatively large, hairy, velvety, resupinate and arranged in a short spike. The dorsal sepal and petals overlap to form a hood over the column with the lateral sepals spreading apart from each other. The labellum is relatively large with two sections - an upper "epichile" and lower "hypochile" separated by a narrow section. The hypochile has a cylinder-shaped spur containing two large glands and is joined to the epichile with a "claw" that has spreading teeth or a long fringe. The fruit is a hairy capsule containing a large number of winged seeds.{{cite web |title=Anoectochilus |url=http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=101904 |publisher=Flora of China |accessdate=29 August 2018}}{{cite web |title=Genus: Anoectochilus |url=http://goorchids.northamericanorchidcenter.org/genus/anoectochilus/ |publisher=North American Orchid Conservation Center |accessdate=29 August 2018}}

Taxonomy and naming

The genus Anoectochilus was first formally described in 1825 by Carl Ludwig Blume and Anoectochilus setaceus was the first species he described, hence it is the type species.{{WCSP | 10242 | Anoectochilus setaceus }} The genus name is derived from the Ancient Greek words anoiktos (ἀνοικτός) meaning "opened" and cheilos (χεῖλος) meaning "lip".Backer, C.A. (1936).
