Pomatocalpa, commonly known as bladder orchids,[2] or 鹿角兰属 (lu jiao lan shu),[3] is a genus of about twenty five species from the orchid family, Orchidaceae. Plants in this genus are epiphytes or lithophytes with thick, leathery leaves and a large number of small flowers with a three-lobed labellum. There are about twenty five species found from tropical and subtropical Asia to the south-west Pacific.
Description
Orchids in the genus Pomatocalpa are monopodial epiphytic or lithophytic herbs with long, thick roots attached to the substrate, with fibrous stems and long-lasting leaves arranged in two rows with their bases obscuring the stems. A large number of relatively small flowers are arranged on a panicle or raceme and with sepals and petals that are similar to each other and a labellum that has three lobes.[2][3][4][5]
Taxonomy and naming
The genus Pomatocalpa was first formally described in 1829 by Breda in Genera et Species Orchidearum et Asclepiadearum. The type species is Pomatocalpa spicatum.[6] The name Pomatocalpa is derived from the Ancient Greek words pomatos meaning "cover", "lid", "operculum" or "gill-cover"[7]: 183 and kalpe meaning "vessel for drawing water", "pitcher" or "urn",[7]: 627 referring to the deeply pouched labellum.[4]
