Anoectochilus, commonly known as marbled jewel orchids[3] or filigree orchids,[4] is a genus of about fifty species in the orchid family Orchidaceae. 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[edit]

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.[3][4][5][6]

Taxonomy and naming[edit]

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.[7] The genus name is derived from the Ancient Greek words anoiktos (ἀνοικτός) meaning "opened" and cheilos (χεῖλος) meaning "lip".[8]

Distribution[edit]

Orchids in this genus range from the Himalayas to south China, Southeast Asia, Australia, New Guinea, Melanesia and Hawaii,[9] found in moist areas with deep shade.[3][4]
