purple-tipped, about 1 cm. long. Banner very large, nearly the 
whole of it erect, about 8 mm. long and almost round, arched gently, 
2-7 mm, longer than keel, with sides reflexed 1 mm. wide, Wings 
broad, oblong to lanceolate-lunate, about 3 mm. wide, rounded, arched 
about 30 degrees. Keel 7 mm. long, as long as wings, dark-tipped, 
produced and with a long acute and erect tip 1 mm. wide. Calyx 
tube nigrescent, reflexed, short-campanulate, 3 mm. long, nearly ses- 
sile, scarcely oblique and the base slightly narrowed, not flattened, 
with rounded sinuses; teeth triangular to subulate, unequal, con- 
spicuous, about 2 mm. long. Pedicels very short and stout. Bracts 
ovate, 2 mm. long. Peduncles 5-15 cm. long, hardly longer than the 
leaves, many, in most of the axils, Leaves 5-10 cm. long, the petiole 
almost none, short or not over 2 cm. long. Leaflets 6-10 pairs, nor- 
mally about 7 mm. long, rarely 2.5 cm. long, ovate to linear, rather 
thick, acutish to rounded, with prominent midrib, green. Stipules 
rather large, green or purple above, smaller and connate below. 
Stems decumbent at base, rarely a foot long, much branched at base 
and from long underground stems, but from a stout and erect root. 
Internodes rather short and leaves many mostly. Whole plant pubes- 
cent with partly spreading soft and fine hairs, but variable, This 
grows on rocky ridges and among sagebrush from the Middle Temper- 
ate to the Upper Temperate life zone, sometimes seemingly alpine 
but not truly so. Common in the Sierras and northward from Reno, 
possibly in the Blue Mts. Oregon.

Phaca Heller. Pods nearly boat-shaped, half-elliptical, with ventral 
suture convex in the middle and concave toward the ends, dorsal su- 
ture very convex, the calyx ascending but pods somewhat drooping, 
papery, appearing smooth and translucent. Flowers about 15 mm.

to erect beyond calyx tips, the sides reflexed about 1 mm. wide, 3-4

2 mm. longer than keele. Keel about 5 mm. long, with long, exserted 
claw, the base nearly straight, then gently rounded to nearly erect with 
a broadly triangular and very obtuse tip about 3 mm. high, not dark- 
tipped. Calyx scarcely gibbous, acutish at base and fleshy at the in-
