Authors: Hang Sun & Les Pedley

Lianas. Apical vegetative bud dormant during anthesis and fruit set. Stipules and stipels persistent. Racemes in axil of terminal leaves forming a leafy panicle; bracts longer than corresponding flowers, caducous. Bracteoles present. Calyx campanulate, subtrun­cate, bilabiate. Corolla standard reflexed at base, calluses absent; wings and keel ± equally long; wings free from keel. Stamens dia­delphous, vexillary staminal filament distinct from other 9. Ovary glabrous, with 9-12 ovules. Legume linear, cylindric, raised over seeds, dehiscing along adaxial suture; exocarp fleshy but papery when dry; endocarp thin, leathery, lining seed cavity. Seeds ellip­soid; hilum rather elongated, surrounded by prominent rim; radicle folded.

Three species: SE Asia, Pacific islands (Solomon Islands); one species in China.

Sarcodum is here recognized as a genus distinct from Clianthus Solander ex Lindley. Clianthus is now considered to be a genus with one or two species restricted to New Zealand, and the Australian species formerly recognized in Clianthus are referred to Swainsona Salisbury.
