 small rose to white flowers clustered at the nodes of axillary or terminal 

 racemes. Calyx subtruncate, its teeth very short. Standard ovate, with a broad 

 and short claw; wings oblong, falcate; keel curved, larger than the wings. 

 Stamens 9, monadelphous. Ovary nearly sessile, several-many-ovuled ; style 

 short, curved ; stigma terminal. Pod flat, 2-valved, partitioned between the sub-

 times 5-9-foliolate leaves, persistent stipules, and large axillary flowers. Calyx 

 tubular, 5-toothed, the upper teeth more or less united; standard large, erect, 

 retuse, narrowed at the base, not spurred; wings oblong, curved; keel acute, 

 shorter than the wings; stamens more or less monadelphous; anthers all alike; 

 ovary stipitate; style elongated, incurved, hairy along the inner side; pod 

 stalked in the calyx, linear or linear-oblong, flattened, 2-valved, partly septate 

 between the seeds. About 30 species, natives of warm and temperate regions.

Perennial, herbaceous or slightly woody below, slender, twining to a height 

 of 2 m. or more, or, if without support, prostrate, pubescent, at least on the
