Schoenorchis, commonly known as flea orchids,[3] or 匙唇兰属 (chi chun lan shu) in Chinese,[4] 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.
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.[3][4][2][5]
The name Schoenorchis is derived from the Ancient Greek words schoinos meaning "sedge", "rush-rope" or "rope"[6]: 667 and orchis meaning "testicle" or "orchid".[2][6]: 788 This is thought to refer to the terete leaves of some of the species.[7]
The genus Schoenorchis was first formally described in 1825 by Carl Ludwig Blume from an unpublished description by Caspar Reinwardt and the description was published in Bijdragen tot de flora van Nederlandsch Indië.[1][8] The type species is Schoenorchis juncifolia Reinw. ex Blume.[2]
The genus was divided into the sections Pumila, Schoenorchis, and Racemosae.[9][10]
The following is a list of species accepted by the World Checklist of Selected Plant Families as at January 2019:[1]
Orchids in this genus occur in China, the Indian subcontinent, Indochina, Malesia, New Guinea, Fiji, New Caledonia, Samoa, Vanuatu and northern Australia.[1]
The small, entomophilous, colourful flowers of Schoenorchis gemmata produce nectar and fragrance during the daytime and they are believed to be pollinated by insects of the order Hymenoptera.[13] More specifically, pollination by bees has been reported.[2] Apart from insect pollination, autogamy has been also reported to occur, for instance in Schoenorchis paniculata,[13] and possibly in Schoenorchis sarcophylla.[2]
Some species are very rare. Only 20 individuals of Schoenorchis mishmensis K.Gogoi, Mega & Chowlu are known to exist in the wild, and it is therefore thought to be critically endangered.[14]

Garay, 1972 Schoenorchis vanoverberghii Ames, 1915ショノルキス(スコエノルキスとも)属 Schoenorchis はラン科植物の一群。コチョウラン属などに近いが、さほど目立つものではない。
単茎性の着生ラン[1]。茎は直立するか下垂する。茎が短く詰まるとコチョウラン属などに、長く伸びるとヒスイラン属などに似て見える。茎は下部で分枝することが多い。
花茎は茎の側面から出て、多数の花を総状につける。萼片と側花弁はほぼ同型、唇弁は三裂し、側裂片は丸くて立ち、中裂片は肉厚で前に出る。蕊柱は短い。コチョウラン属やカシノキラン属に似ており、蕊柱の構造で区別される。
学名はギリシャ語のヨシ(またはイグサ)とランの組み合わせである。
ヒマラヤからニューギニア、オーストラリア、太平洋諸島に分布し、約10種がある。
一部で洋ランとして栽培される。ただし一般に普及しているほどではない。洋ランとしての略称もない。以下の2種は比較的広く普及している。
