Description

edit

Orchids in the genus Robiquetia are epiphytic, monopodial herbs with pendulous, fibrous, sometimes branching stems and many smooth roots. The leaves are arranged in two ranks and are thick and leathery, oblong to elliptic, with a divided, asymmetrical, tip. Many small, densely crowded flowers are arranged on a pendulous flowering stem that emerges from a leaf axil. The sepals and petals are similar to each other and the labellum has three lobes and an inflated spur on its tip.

Taxonomy and naming

edit

The genus Robiquetia was first formally described in 1829 by Charles Gaudichaud-Beaupré and the description was published in his book Voyage autour du monde from a specimen collected in the Maluku Islands. The type species is Robiquetia ascendens. The name Robiquetia honours the French chemist Pierre Jean Robiquet.[1][3][4]

In Chinese, members of this genus are known as 寄树兰属 (jì shù lán shǔ).[5])
