116 Inflati 



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-hmate, 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, shortcampanulate, 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.

68. Astragalus oxyphysus Gray Proc. Am. Acad. 6 218 (1864). 

 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. 

 long, white, narrow, ascending. Banner oblanceolate, gently arched 

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

 mm. longer than wings. Wings linear, gently arched to 45 degrees about 

 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- 

 sertion with the very thick pedicel, cleft deeper above, with subulate 

 teeth about 2 mm. long. Leaves 1-1.5 dm. long, narrow, very short- 

 petioled. Leaflets 4-10 pairs, not contiguous, 1-2 cm. long, narrowly 

 elliptical, apiculate and obtuse. Internodes about 3 cm. long. Stems 

 flexuous, about 2 ft. high, br;inchrd b^low and woody, no-iriv eror*.

 about 1.5 cm. long, and 6 mm. wide and high, with cross section about 

 round, half-elliptical, about equally triangular-acute at the ends, not 

 at all laterally flattened, in short spikes as are the flowers. Flower.<^ 

 white, stubby, about 1 cm. long. Banner with erect part short and 

 rounded and arched remote from calyx tips. Keel and wings about 

 equal, nearly as long as banner. Calyx campanulate, about 2 mm. long,

 as long as tube and with broad sinuses. Pedicels slender, 2-4 mm. 

 long, longer than the bracts. p-^d'T^r-l-^f^ i-"" '', ri'-;-! i-n'' ';''>" .T'^t*.
