FABACEAE. 205 



alternate anthers smaller; anther-cells confluent at the 

 apex. Pod short, compressed, often curved, prickly, 

 indehiscent, few-seeded. 



1. G. glutinosa Nutt. Erect or decumbent, 6-9 dm. high, 

 nearly glabrous and viscid with minute sessile resinous dots, or 

 glutinous by a villous or hirsute glandular pubescence; leaflets 13- 

 19, oblong-lanceolate, 2.5-5 cm. long; stipules ovate-acuminate to 

 lanceolate, persistent; spikes oblong, 2.5-4 cm. long, on peduncles a 

 little shorter; pod bur-like. 



Occasional in canyons below 4000 feet, in the interior region. 



13. VICIA L. Vetch. 



Herbs with angular stems, more or less climbing by 

 the tendrils at the ends of the pinnate leaves. Calyx 

 5-cleft or 5-toothed, the upper teeth often shorter. 

 Wings of the corolla adhering to the middle of the keel. 

 Stamens diadelphous or nearly so; anthers uniform. 

 Style filiform, inflexed, the apex surrounded by hairs. 



Pod flat, 2-valved. Seeds globular, usually many. 



Perennials. 



Herbage glabrous or nearly so. 

 Herbage villous-pubescent. 

 Annuals. 



Flowers nearly sessile, 15 mm. long. 

 Flowers 6 mm, long, on filiform peduncles. 

 Leaflets obtuse. 

 Leaflets notched. 



1. V. americana Muhl. Glabrous or nearly so, weak, 6-15 dm- 

 high, climbing by branched tendrils; leaflets 8-12, thin-membranous, 

 vivid green above, pale beneath, mostly broadly oblong and obtuse, 

 mucronulate, 1-2 cm. long; peduncles shorter than the leaves, 4-8- 

 flowered; flowers purplish or bluish, about 18 mm. long; calyx-tube 

 4 mm. long; the lower teeth about 2 mm. long, the upper shorter, 

 approximate, incurved. 



Our forms all seem to belong to the two varieties. 



la. V. americana truncata (Nutt.) Brew. Leaflets oblong-elliptic 

 or the lower broadly linear, 15-30 cm. long, truncate or broadly 

 retuse at summit, otherwise like the type. 



Occasional on shaded slopes in the chaparral belt. 



lb. V. americana linearis (Nutt.) Wats. Leaflets narrowly 

 linear, acute, strongly veined beneath, 12-25 cm. long. 



Frequent in the chaparral belt, usually in more open places than 

 the last. 



2. V. calif ornica Greene. Erect or decumbent, rather strict 

 and seldom climbing, 1.5-4 dm. high, villous-pubescent; tendrils 

 short, stiifish, seldom branched; leaflets 8-12, subcoriaceous, deli-
