Zeuxine

Zeuxine, commonly known as verdant jewel orchids,^[2] is a genus of about eighty species of orchids in the tribe Cranichideae. They are native to parts of tropical Africa, Asia, Southeast Asia, New Guinea, Australia and some Pacific Islands. They have relatively narrow, dark green leaves and small, dull-coloured resupinate flowers with the dorsalsepal and petals overlapping to form a hood over the column. The labellum has a pouched base and its tip has two lobes.

Orchids in the genus Zeuxine are terrestrial, perennial, deciduous, sympodialherbs with a fleshy, creeping, above-ground rhizome anchored by wiry roots. The leaves are thinly textured and stalked, arranged in a rosette at the base of the flowering stem or scattered along it. Small, resupinate dull-coloured flowers are often crowded along the short flowering stem which usually has protruding bracts. The dorsal sepal and petals overlap, forming a hood over the column. The lateral sepals overlap the base of the labellum which is usually white, has a pouched base and a number of stalkless glands. The column is short with two stigmas.^{[2][3][4][5][6]}

The genus Zeuxine was first formally described in 1826 by John Lindley who gave it the name Zeuxina but Zeuxine is the nom. cons. The description was published in the appendix of Collectanea Botanica.^[1][7][8] The name Zeuxine is derived from the Latin word zeuxis meaning "joining" or "yoking"^[9] in apparent reference to either the partly fused column or to the pollinia.^[3]

Plants in the genus Zeuxine usually grow in dark, moist forests where the humidity is always high or near swamps and seepage areas. They occur in tropical regions between Africa and Asia, in Southeast Asia, New Guinea, Australia and some Pacific Islands. Fourteen species are endemic to China and ten in Taiwan. Zeuxine strateumatica is naturalised on the Hawaiian Islands and in the south-eastern United States.^[3][4][5][6]
