Hamosi. 261 



Calyx tube about 3 mm. high, reddish, the filiform-subulate teeth 

 very lax and about as long as tube. Pedicels almost none to 2 

 mm. long, much shorter than the subulate to triangular bracts 

 which are 3-4 mm. long, hairy and hyaline. Peduncles stout 5-10 

 cm.' long, the fruiting rachis about as long, spreading. Leaves 

 rarely 5 cm. long, rather broad, all petioled but upper petioles 

 short, spreading. Leaflets rather thick, 6-8 pairs, hardly 1 cm. long, 

 folded. Stipules small, connate below, triangular. Stems flexuous, 

 about 1-2 ft. high, from a woody base, rather Jiiiany. Sierra 

 Valley to Owen's Valley California on the eastern base of the 

 Sierras growing in the sagebrush, Lower Temperate life zone. 

 Whole plant softly silky-woolly. Blooming in May. The Owen's 

 Valley forms have larger and purple flowers and pods 5 mm. high and 

 2 cm. long. 



226. Astragalus sylvaticus Watson Proc. Am. Acad. 23 262 

 (1888). a; umbraticus Sheldon. Pods not tapering at base, ob- 

 tuse or abruptly acutish, smooth and shining, closely reflexed, char- 

 taceous, arched to a half circle, about 1.5 cm. long, 2-3 mm. high 

 and 1 mm. wide, narrowly and deeply sulcate dorsally, with cross 

 section narrowly Y-shaped, tip triangular-acute, ventral suture a 

 mere line and not raised. Flowers white, many, in a short spike, 

 drooping, about 1 cm. long, with delicate petals and none col- 

 ored except keel tip, not narrow. Banner about 5 mm. long, oblong- 

 ovate, abruptly arched at calyx to nearly erect, fiddle shaped by 

 the sides being reflexed most near the middle (and about 2 mm. 

 wide) ; groove broadly V-shaped, about 1 mm. deep and 2 mm. wide 

 and goes almost to tip of banner without shallowing, deeply notched, 

 cream-white, faintly waterlined. Wings close-pressed to keel and 

 convex to it to the middle then the right hand one flares, very 

 obliquely oblong-lanceolate, 2 mm. wide, very obtuse and rounded 

 and erose at tip, 1 mm. longer than keel and about as much shorter 

 than .banner. Keel large, about 3 mm. long and high, arched from 

 base to about a half circle. Calyx oblong-campanulate, about 3 mm. 

 long, a little flattened laterally, yellowish and nigrescent, the lower 

 side straight, the upper a little arched, rather oblique at base and 

 attached a little below the middle, cleft deeper and oblique at mouth. 

 Teeth filiform from rounded sinuses. Pedicels about 1 mm. long. 

 Bracts hyaline, triangular-subulate, about 3 mm. long and lax. 

 Peduncles slender, strict, about as long as leaves and 1 dm. long, 

 in the upper axils, the rachis about 2-3 cm. long and closely flow- 

 ered. Leaves slender, not over 1 dm. long, spreading, the upper 

 sessile, with tapering and filiform rachis, only the uppermost leaf- 

 lets reduced. Leaflets about 10 pairs, oblong-elliptical, notched, 

 rounded and very short-petiolulate at base, green, flat, thin, con- 

 tiguous, smooth or nearly so. Stipules about 1 cm. long, subu- 

 late, hyaline above. Stems about 2 ft. long, slender, flexuous 

 ascending to erect, with internodes 2-7 cm. long, from slender and 

 erect tap root, several at the small crown. The root leaves much 

 reduced. In shaded woods in open places in rich soil. Glendale, 

 Oregon, Middle Temperate life zone. 



227. Astragalus albens Greene Bull. Cal. Acad. 3 156 (1885). 

 Pods broadly linear, acuminate at both ends, arched mostly to a 

 circle, a trifle wider above, when young much laterally flattened and 

 little arched, when mature coriaceous, strongly corrugated, 2-3 cm. 

 long, 3 mm. wide and high, flat for about 1 mm. high along the 

 ventral suture and forming a thick wing but the suture itself not 

 raised, then much bulged outward in neai'ly a half circle and re- 

 entering as a broad sulcus on the dorsal suture so that the cross 

 section of pod is deeply cordate and winged at the tip, each cell 

 being oval, 2-celled throughout or the partition reaching only half 

 way to the ventral suture, the base of pod is 3-cornered like a file, 

 the tip is very sharp and flat because the sulcus stops about 5-8 mm. 

 from the end, ashy. Flowers few and racemose, purple, about 8
