 than the leaves; loosely 7-30-flowered ; bracts subulate, longer than the 

 pedicels ; flowers 6-9 lines long, light purple ; teeth of the calyx subulate, 

 about as long as the tube; pods 3-4-jointed, minutely pubescent. Wash- 

 ington to the Rocky Mountains and far northward. 



H. flavescens Coult. & Fish. Bot. Gaz. xviii, 300. Stems slender, a 

 foot or more high, puberulent : stipules lanceolate, acuminate, the lower 

 ones connate; leaflets 9-15, oblong to lanceolate, 8-12 lines long : pedun- 

 cles longer than the leaves, loosely many-flowered; calyx campanula te, 2 

 lines long, the somewhat unequal teeth about as long as the tube; flowers 

 cream-color, 8 lines long, the broad keel conspicuously longer than the 

 wings and banner, on slender pedicels: joints of the pods 2-3 lines broad, 

 usually only 2 maturing, the lowest one aborting and serving as a stipe.

Tribe 8. Viciese, Bronn. Diss. 133. Herbs with abruptly pin- 

 nate leaves, the common petiole not articulated with the stem, pro- 

 duced at the apex into a tendril or bristle. Corolla papilionaceous.

15 VICIA Tourn. Inst. t. 221. L. Gen. n. 873. (Vetch, Tares.) 



Weak herbs with angled stems, more or less climbing by 

 branched tendrils that terminate the leaves, pinnate leaves, semi- 

 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- 

 valved, short-stipitate or sessile, not jointed. Seeds globular, 

 the stalk expanded above to cover the linear hilum. 



* Perennials: flowers in pedunculate secund racemes. 



V. gigantea Hook. Fl. i, 157. Stout and tall, climbing several feet 

 high, somewhat pubescent or puberulent : leaves 6 inches long or more ; 

 stipules narrow, deeply and sharply toothed in the middle : leaflets 10-15 

 pairs, oblong-lanceolate, obtuse, mucronate, 1-2 inches long:, entire : 

 peduncles shorter than the leaves, 5-18-flowered ; flowers ochroleucous, re- 

 flexed on short pedicels, 6 lines long; upper calyx-teeth very short, tri- 

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

 glabrous, 3-4-seeded, black when mature. Common in woods and moist
