Nephrangis Summerh. in Kew Bull. 2: 301 (1948).
Epiphytic monopodial herbs. Stem long, leafy, simple or branching. Leaves distichous, needle-shaped. Inflorescences arising along the stem opposite the leaves, 1–6-flowered, shorter than the leaves. Flowers small, translucent, brownish or green-brown. Sepals and petals spreading or reflexed; lip spurred. Column short; rostellum elongate, porrect, shortly recurved at the apex; anther ovate, cucullate, broadly rostrate, obtuse; pollinia 2, ellipsoid, each with a short spathulate-liguliform stipes; viscidium 1, triangular, rounded, truncate.
Derivation of name:
The name is derived from two Greek words nephros (kidney) and angos (vessel), referring to the kidney-shape labellum of the type species.
Nephrangis filiformis (Kraenzl.) Summerh,
This orchid is quite widely distributed in tropical Africa but rarely collected. It was first described from Zaire. Cultivation:
This orchid has not been grown in cultivation so far as I know. I would expect growers to be successful with it as a mounted plant given the same treatment as the warmer growing species of Tridactyle.
