 specimens collected by Mr. Coulter in 1872 on Henry's Fork of Snake 

 Eiver.

Var. (?) Villous with spreading hairs, dwarf, acaulescent; leaves, in- 

 cluding the petiole, !'; leaflets in about 11 pairs, ovate, 2 // -3 // long;

 panulate, 5-toothed, teeth obtuse half the length of the tube; corolla 

 4" long, banner reflexed, petals of the keel nearly distinct, acuminate, 

 inucrouate. Hall & Harbour, 146; Dr. Smith. Abundant on the plains 

 around Denver, Porter. Ute Pass and Clear Creek Canon, Coulter. 

 Lower branches elongated and far exceeding the fruiting racemes.
