Abstract
Rohdea medogensis, a new species from Tibet, China, is described and illustrated. This species is similar to R. verruculosa in sharing characters of the perianth with ringed, fleshy appendage in throat and lobes abaxially with verruculose, but differs mainly by bracts 3 per flower, with several sterile bracts apically; outer bract ca. 4.5 cm long, ca. 3 mm broad; perianth globular; lobes shorter ca. 2.0 mm long, margin lacerated, apical subacut; the top of annular appendage margin lacerated, 2 mm above the top of perianth tube; stigma bend, without lobed; style conspicuous; ovary globose or subglobose, askew; berry and seed ellipsoid, askew.
