141 Attrtgalus recurvus Greene Hull. Cal. Acad. 3 155 (1885). 

 Po is ai)oat S liim. 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 th« curve of the dorsal suture which is conspicuously con- 

 cave and the ventral very convex, making the pod much recurved. Flow- 

 c. s dull-white. Banner oval, abruptly arched to erect at end of caly.x, 

 about 3 mm. long, with sides reflexed a little at base, the blade fan- 

 ve>ne 1 with purple and with purplish sides much as in A. obscurus, 

 barcy surpassing wings and keel. Wings very obliquely obovate and 

 about 3 mm. long and Z 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 wliole keel nearly erect and tri- 

 angular, about 3 mm. long and high, darker at tip. Caly.x tube 

 etiually attached on pedicel and not obli(|ue. 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 th« 

 Grand Cinon. .Mddie Temperate life zone. Blooms in summer. 



142 Astragalus stratureniis Jones Gout. 8 19 (1898). Pods arcu- 

 ate upward or .-.craight, 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-rcniform, 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 wav}' on the mar- 

 gin. Flowers in racemes which are often twice as long as the peduncle, 

 many, with deep-purjde 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; while 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. Ions; 

 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 unc(jually 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. It is 

 po«;sible that this is an extreme form of .A. strigulosus var. breviden- 

 tatus. 



143 Astragalus strigulosus TLB.K. Nov. Gen. & Sp. 6 494 (1824). 

 pods about 4 mm, wide, about 2 cm. long in the type, triangular-acute 

 at both end^ and with a flat deltoid beak ending iu the long subulate 

 • tyle, variably pointer!, 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 be yellowish when dry. Banner almost round, about 3 mm. long, 

 abruptly 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 lincar-oblinceolate, wavy, narrowed at tip, almost acute, about 

 1 mm, wide, much narrower than keel, fully as long as banner and
