141 Astragalus recurvus Greene Bull. Cal. Acad. 3 155 (1885). 
Pods about 3 mm. high, sulcate nearly to the middle and with sep- 
tum intruded almost to the ventral suture, with wavy margins, taper- 
ing into a stipe shorter than the calyx and triangular-acute with the tip 
following the curve of the dorsal suture which is conspicuously con- 
cave and the ventral very convex making the pod much recurved. Flow- 
ers dull-white. Banner oval, abruptly arched to erect at end of calyx, 
about 3 mm. long. with sides reflexed a little at base, the blade fan- 
veined with purple and with purplish sides much as in A. obscurus, 
bareiy surpassing wings and keel. Wings very obliquely obovate and 
about 3 mm. long and 2 mm. wide, whitish at tip, arched till tips are 
nearly erect. Keel arched from base to a half circle and with the tri- 
angular and acutish tip erect, or the whole keel nearly erect and tri- 
angular, about 3 mm. long and high, darker attip. Calyx tube 
equally attached on pedicel and not oblique. Peduncle and floral ra- 
chis about equal. Leaves hardly 1 dm. long. Leaflets distant, about 
8 pairs, about linear, 5-8 mm. long. Stipules connate. Stems about a 
foot high, decumbent below, minutely pubescent. This was first col- 
lected by Palmer at Prescott. It grows in the open pine forests of the 
Mogollons of northern Arizona from Prescott to Flagstaff and the 
Grand Canon. Middle Temperate life zone. Blooms in summer. 
142 Astragalus straturensis Jones Cont. 8 19 (1898). Pods arcu- 
ate upward or straight, but the tip with a convex hump along the ven- 
tral suture and declined, papery, about 2 mm. high and 3 mm. wide, 
with cross-section rather oblately deltoid-reniform, rather abruptly 
contracted at base into a stipe at least as long as calyx, and abruptly 
and very obliquely apiculate at tip, sulcate to the middle and with the 
septum extended to the ventral suture which is not wavy on the mar- 
gin. Flowers in racemes which are often twice as long as the peduncle. 
many, with deep-purple banner. white wings and purple-tipped keel. 
Banner broadly ovate, about 4 mm. long, notched, abruptly arched at 
calyx tips to 45 to 60 degrees, streaked with heavy purple lines within 
which are lighter on the outside; groove broad and shallow and about 
a third of a circle at base and nearly vanishing above; white spot hard- 
ly evident except when color is deep; sides of banner reflexed 1 mm. 
wide below and but little above. Wings arched at keel tip to 45 de- 
grees, oblong-ovate, barely acutish, darker below, about 3 mm. long 
and 1 mm. shorter than banner and 1 mm. longer than keel, 1-2 mm. 
wide, concave to keel, one is vertical, the other horizontal and spread- 
ing. The keel extends about 2 mm. beyond calyx, arched to about 
two thirds of a circle, short-triangular, acutish, with straight base. 
Calyx tube nearly hemispherical, not gibbous, a trifle flattened above. 
slightly unequally attached. Fruiting rachis'often a foot long. Leaves 
about 1 dm. long. Leaflets about 6 pairs, normally elliptical to lance- 
olate (rarely some of the lower ones oval), obtuse to retuse, generally 
folded, 1-2. cm. long, long-petiolulate, cuneate at base. lighter below, 
appearing as if glaucous, almost smooth. Stipules triangular, green, 
reflexed, not connate, small. Stems often 3 ft. long and straggling, 
slender, nearly simple from an open base, with internodes 2-7 cm. long. 
This grows in the Pine Valley mountains Utah, among oak brush, on 
southern slopes, blooming in May, Middle Temperate life zone. Itis 
possible that this is an extreme form of A. strigulosus var. breviden- 
tatus. 
143 Astragalus strigulosus H.B.K. Nov. Gen. & Sp. 6 494 (1824). 
pods about 4 mm, wide, about 2 cm. long in the type, triangular-acute 
at both ends and with a flat deltoid beak ending iu the long subulate 
style, variably pointed, inclined to be ashy, speckled, with dorsal su- 
ture somewhat intruded. Flowers rather densely racemose, even spi- 
cate seemingly when young, many in the type, whitish, and inclined 
to bé yellowish when dry. Banner almost round, about 3 mm. long, 
arched to erect or more at end of calyx tube, and thus even 
_ the keel seems to protrude beyond it, with sides much reflexed. The 
. wings linear-oblanceolate, wavy, narrowed at tip, almost acute, about — 
Imm, wide, much narrower than keel, fully as long as banner and _
