This plant differs from Astragalus haydenianus A. Gray in 

 the taller, more rigid stems, which, together with the leaves, 

 are minutely rough-pubescent throughout ; in the larger, nar- 

 rowly triangular- oblong, pointed pods, which are more dis- 

 tinctly transversely rugose veined, with the ventral surface 

 not so deeply divided by the suture, but with the dorsal suture 

 very prominent, and with stipes twice exceeding the calyx. 



It is also distinct from the more northern Astragalus bisul- 

 catus A. Gray, in which species the violet- colored flowers are 

 characteristic. The range of this species is, so far as deter- 

 termined, from Kansas to Utah.
