ASTRAGALUS HayDENIANUS Gray var. MAJOR. Subdecumbent 
or nearly erect; leaflets 7 to 9 pairs, narrowly elliptical to linear- 
lanceolate, very obtuse, apiculate; whole plant nearly glabrous, but 
pods more pubescent and pedicels villous; bracts narrowly lance- 
olate, acuminate, longer than the pedicels; calyx deeply cleft, 1% 
lines wide and long, exclusive of the lobes, with scattered black 
hairs and black-ciliate throat; lobes with a deltoid base and 1% 
_ lines long or less; flowers 6 lines long, cream-white; banner ascend- 
ing; claws of wings conspicuous; flowers twice as narrow as A. 
bisulcatus; pods spreading but seldom pendent, narrowly oblong- 
elliptical, rugulose-veiny, straight, or generally curved, 5 lines long 
by 1% lines wide, shortly acute at both ends, ventral groove not so 
deep and the dorsal also a little impressed.

obtuse or retuse; whole plant nearly glabrous, but calyx and young 
_ pods pubescent with white hairs; bracts rather broadly lanceolate 
and scarcely acute, shorter than the shortly-white-villous 2-line-long 
pedicels;. calyx a little over a line long and wide exclusive of the 
lobes; lobes nearly equal in length and shorter than the tube; flowers 
4 lines long and 1 line wide, nearly white, subverticillate and very 
numerous, soon reflexed; banner reflexed, shorter; wings scarcely 
equaling the keel; pod not evidently rugulose, short-pubescent, 
about 5-seeded, papery, nearly or wholly pendent, barely acute at 
each end, elliptical, 4 lines long and 2 lines wide, or smaller; proper
