 Softly pubescent; stems subdecumbent, about 1° long; stipules small; 

 leaflets 7-10 pairs, 4-6" long, linear-oblong, obovate or obcordate ; pedun- 

 cles much longer than the leaves ; racemes spike-like, with spreading or pen- 

 dulous flowers on short suberect pedicels; calyx-teeth subulate, or ovate, 

 3-times shorter than the tube ; corolla 6-8" long, ochroleucous, half longer 

 than the calyx ; legume cartilaginous, 1-celled, subHnear, terete, acute at each 

 end, pendent upon a stipe longer than the calyx, strongly arcuate-incurved or 

 sometimes annular, margined sutures narrow, the ventral one very acute. — 

 Washington Territory, (Spalding;) near Carson City, Nevada, (Dr. Anderson.) 



Astragalus pilipes, Torr. Qray's Rev., I. c, 226. Perennial, minutely 

 puberulent ; stems 2° long, subdecumbent, simple or branched ; stipules 

 small, free ; leaflets ¥ long, 5-8 pairs, linear-oblong, obtuse ; peduncles 

 slender, much exceeding the leaves ; racemes loosely 10-20-flowered ; flowers 

 I' long, ochroleucous, on slender pedicels, spreading ; calyx-tube campanu- 

 late, twice longer than the short teeth ; legume 1' long, chartaceous, long-
