15 VICIA Tourn. Inst. t. 221. L. Gen. n. 873. (Vercu; Tarzs.) 
Weak herbs with angled stems, more or less climbing by

sagitate usually foliaceous stipules, and numerous, rarely few 
or solitary, flowers in loose peduncled axillary racemes. Calyx 
5-cleft or toothed, usually unequal. Wings of the corolla ad- 
herent to the middle of the short keel, the banner obovate or 
oblong, free. ‘Stamens diadelphous or nearly so, the mouth of 
the sheath oblique; anthers uniform. Ovary two to many- 
ovuled ; style filiform, bent at right angles to the ovary, the apex 
surrounded by hairs or hairy on the outside. Pod flat, two-

the stalk expanded above to cover the linear hilum. 
* Perennials: flowers in pedunculate secund racemes.

angular, the lower longer, subulate: pods broadly oblong, 16-18 lines long,
