ANGADENIA. 
This genus is proposed for a small group of fruticose plants, erect or scandent, chiefly 
referred by Müller to Odontadenia and Anisolobus, differing from the former in their 
floral and carpical characters, and from the latter in their small, equal, coriaceous 
sepals, and in the shape and mode of zstivation of the segments of the corolla, and other 
features.

A climbing plant, with slender, flexuous, glabrous branches, having axils 5 in. apart, 
bearing on their transverse ridge 2 thick ovate or linear-oblong glands; leaves ovate- 
oblong, cordate at the base, rounded and emarginate at the summit, very glabrous above,
