Luisia, commonly known as velvet orchids[3] or 钗子股属 (chai zi gu shu),[4] is a genus of epiphytic or lithophytic orchids in family Orchidaceae. Plants in this genus have flattened roots, long leafy stems, narrow, thick, leathery leaves and short-lived flowers that open sporadically. There are about forty species found from tropical and subtropical Asia to the Western Pacific.[1]


Orchids in the genus Luisia are epiphytic or lithophytic, monopodial herbs with long, fibrous stems and thick, more or less flattened roots. A large number of cylinder-shaped, narrow leathery leaves are arranged along the stems. Up to ten resupinate, usually small, fleshy flowers are arranged on a short, thickened flowering stem and open sporadically. Each flower has a short, curved stalk and petals that are longer than the sepals. The labellum is large and fleshy with an upper epichile separated by a groove from the lower concave hypochile. The labellum has a rigid connection to the column.[3][4][5][6]

Taxonomy and naming[edit]

The genus Luisia was first formally described in 1829 by Charles Gaudichaud-Beaupré and the description was published in Voyage autour du monde fait par ordre du Roi sur les corvettes de S. M. l'Uranie et la Physicienne.[1][7][8] The name Luisia honours Don Luis de Torres who assisted the French expedition at Guam.[8][9]


Orchids in the genus Luisia occur in Bhutan, China, India, Indochina, Indonesia, Japan, Malaysia, New Guinea the Philippines, Sri Lanka, Thailand, Australia, Micronesia and Melanesia.[1][4]
