Neuwiedia Bl.

三蕊兰属

Description from Flora of China

Herbs, erect. Rhizome usually retrorse, with several stout aerial roots. Stem often stiff and woody at base, not branched. Leaves several to many, plicate, basally contracted into a clasping, petiole-like stalk. Inflorescence erect, terminal, racemose, not branched; peduncle with several foliaceous sterile bracts; floral bracts relatively large, green. Flowers resupinate, almost actinomorphic, not opening widely; ovary 3-locular, distinct from pedicel. Sepals and petals often connivent. Sepals similar or lateral ones slightly oblique, fleshy. Petals similar; lip usually slightly different in shape and larger than petals. Column straight, often short, with 3 fertile stamens; central stamen often shorter than lateral ones; lateral stamens often with locules unequal in length; anthers free but filaments connate at base and adnate to style for much of their length; pollen not cohering to form pollinia; style narrowly cylindric, apex with slightly dilated stigma. Fruit either a berry or a dry capsule dehiscent at maturity. Seeds black, with rigid testa, sometimes with dilated elongate appendages at both ends.

About ten species: from S China through SE Asia and New Guinea to the SW Pacific islands; one species in China.
