Schoenorchis, commonly known as flea orchids,[2] or 匙唇兰属 (chi chun lan shu),[3] is a genus of flowering plants from the orchid family, Orchidaceae. Plants in this genus are small epiphytes with thin roots, thin leafy stems with leaves in two ranks and tiny fragrant, almost tube-shaped flowers with a prominently spurred labellum. There are about twenty five species found from tropical and subtropical Asia to the Western Pacific.

Description

Orchids in the genus Schoenorchis are small epiphytic, monopodial herbs with thin roots, sometimes with branching stems and flat to almost cylindrical leaves with their bases sheathing the thin, fibrous stems. The flowers are small, fleshy, fragrant, often white or reddish purple and do not open widely. The sepals and petals overlap at the base so that the flowers often appear tube-shaped. The labellum is rigidly fixed to the column, usually longer than the petals and has three lobes with a spur at its base. The side lobes of the labellum are erect and the middle lobe is often spatula-shaped.[2][3][4][5]

Taxonomy and naming

The genus Schoenorchis was first formally described in 1825 by Carl Ludwig Blume from an unpublished description by Caspar Reinwardt and the description was published in Bijdragen tot de flora van Nederlandsch Indië.[1][6] The name Schoenorchis is derived from the Ancient Greek words schoinos meaning "sedge", "rush-rope" or "rope"[7]:667 and orchis meaning "testicle" or "orchid".[4][7]:788
