Schell Creek Mountains only. It may, however, exist on the Deep 

 Creek Mountains. It is one of the earliest bloomers, close to snow. 

 It is inclined to spread from the roots, but never forms mats. It is 

 rare. Banner white or dirty, tinged with yellow, varying to light 

 lead colored, bent abruptly to 45°, from mouth of calyx, concave, 

 and so the sulcus is very widely V shaped, hooded at apex by the 

 narrowing of the sulcus, 3 lines long, notched, and often with acces- 

 sory notches, about as broad as long but a little wider at base than 

 apt-X, sides not reflexed or but Httle, slightly purple veined opposite 

 mouth of calyx; wings arcuate upwards and exposing the whole keel, 

 obliquely lanceolate oblong, or nearly so, obtuse tip bent outward form- 

 ing with the keel the letter T, just equaling the keel; keel abruptly 

 bent 90°, purple, dark at tip, point rounded, equaling the banner; 

 pod dark and dark purple mottled, ovate, ^ hy }4 inch, abruptly 

 pointed, straight, papery, and much inflated, oblong oval, cross 

 section oval contrary to the partition and emarginate on each side, 

 prostrate when ripe. Scapes erect to decumbent. July. 



Astragalus Toanus n. sp. Allied to A. nndns. Lower leaflets 

 3 to 6 pairs, upper ones reduced to the long and cylindrical rachis; 

 pods 2 to 4 on the ends of rather long peduncles; erect, ^ to an 

 inch long, 3 lines wide, compressed, erect, straight or curved, acute, 

 thick and corrugated, both sutures prominent; sessile, lanceolate 

 oblong, with very acute edges, cross section elliptical, seeds i}^ by i 

 lines, calyx teeth minute, triangular; calyx 3 lines long. This grows 

 in clumps like the others of the section. It is nearly glabrous 

 throughout, erect, 2 feet high. It was out of flower July 21, 1891. 



Found on the slopes of the Toano Range, Enstern Nevada, in 

 open ground. It can neither be referred to A. Jiiidiis, A. pectinatus., 

 ox A. Grayi, but is intermediate between A. nudus and A. pectinatus. 

 It may be that all four are forms of one polymorphous species, but I 

 do not know of connecting forms. 



Astragalus artipes Gray. This plant is so like A. Bcckwithii 

 (except possibly the fiddle-shaped corolla) that it will be passed over 

 generally when not in fruit; however, the calyx teeth about equal the 

 tube, and are thread-like at tip; pod i^ by ^ inches, spotted, 

 straight, tip slightly curved and almost blunt, base truncate; stipe 

 equaling the calyx teeth; no apparent dorsal suture, ventral not 

 prominent nor inflexed; pod probably round in cross section but
