7. Astragalus Californicus (Gray) Greene Bull. Cal. Acad. 3 157 
(1885). A. collinus var. Californicus Gray Proc. Am, Acad. 12 54 
(1876). Pod about triangular at each end in the type and straight but 
varying to acuminate at both ends and very arcuate, 45 mm, wide, the 
cross section elliptical, rather closely racemose, smooth when old, 
minutely hairy when young, pendent, finely reticulated throughout, 
about the same width throughout, opening first at tip. Flowers white, 
1-1.5 cm. long, shortly and densely racemose, spreading. Banner 7-10 
mm. long, oval, arched to about 45 degrees and abruptly at end of 
calyx, with sides much reflexed from the base, 3-4 mm. longer than 
wings. Wings linear, about 1.5 mm. wide arched sometimes to 45 de- 
grees, about 2 mm. longer than keel. Keel with straight base, about 
4 mm. long, abruptly arched to erect, the triangular tip rather nar- 
row and 3-4 mm. high, and inclined to truncate, yellow at very tip. 
Calyx about cylindric, about 5 mm. long and 3 mm. high, very 
slightly narrower below, hairy, white and hyaline, the upper side a 
trifle arched and the lower straight, attached at the lower 
and fleshy corner and nearly truncate there, a trifle oblique at tip, 
the triangular teeth hardly one-fourth as long and nigrescent. Pedi- 
cels in flower 1-3 mm. long and about as long as the triangular to 
subulate papery bracts, in fruit sometimes 6 mm. long and twice as 
long as bracts. Peduncles about as stout as stems, sulcate, strict, 
1-1.5 dm. long, about twice as long as leaves, the floral rachis nearly 
as long. Leaves 5-7 em. long, the upper sessile, a little longer than 
the internodes. Leaflets 7-10 pairs, 5-12 mm. long mostly folded, acut- 
ish to rounded, broadly linear to linear-oblanceolate, not contiguous, 
not opposite, cuneate and long-petiolulate at base, hoary with soft and 
spreading wavy almost woolly hairs fixed by the base. Stems not 
slender, decumbent below, a little flexuous, about 2 ft. long, sulcate and 
green, tufted from rather woody root. Stipules triangular-subulate, 
rigid and reflexed, green above, hyaline below and connate, small. The 
stipe in type is hardly longer than the calyx but other plants have 
-stipe half as long as the pods and 5 times as long as calyx. In the 
valleys adjoining Mt. Shasta California on the north. Middle Tem- 
perate life zone, in gravelly places. Blooming in April and May. 
8. Astragalus inversus Jones Cont. 5 276 (1893). Pods nearly 
horizontal or a little reflexed, 2.5-4 cm. long exclusive of the rather 
stout and tapering stipe which is about 1 cm. long, reddish when fresh 
and purplish when dry, 4-6 mm. high, nearly flat when dry but 
little so when fresh, straight or only a little arcuate. Flowers very 
loosely racemose, few, ascending, purplish, about 1 cm. long. Banner 
pinkish when fresh, with red stripes on the outside, about 1 cm. long, 
elliptical-oblong, a trifle wider below, ascending 45 degrees in a 
gentle arc from end of calyx tube, 4 mm. wide below, 3 mm. wide at tip, 
notched barely, with sides reflexed 2 mm wide below, appearing fid- 
dle-shaped by the suleus being very narrowly U-shaped at base and 
widening above at the tip where the sides are not at all reflexed, 
sulcus 1 mm, deep below, becoming a mere line above; white spot 
barely visible but its place taken by purple veins. Wings obliquely 
oblanceolate, ascending 30 degrees, 3 mm, wide, concave to keel 
and flaring, the left hand one the most so, erose at the acutish tip, 
pinkish with stripes, nearly 2 mm. longer than keel. Keel lunate, about 
2 mm. wide in the middle, acute at both ends and equally arched from 
base to the erect tip which is yellowish and darker, base of keel 
nearly round in cross section. Calyx tube round in cross section, cam- 
panulate, about 3 mm. long and 2 mm. high, red, nearly equally inserted 
at the acutish fleshy base, teeth minute, triangular from a broad base 
Pedicels stout 1-2 mm. long and about as long as the small, greenish, 
Ovate bracts. Peduncles often a foot long, green and sulcate as are 
the stems and leaves, very slender and falcate, the few flowers scat- 
tered along the upper end. Leaves about 1 dm. long, all petioled with the ;
