^ Astragalus Peabodianus n. sp. Inflati. Perennial, matted 

 caespitose from a branching root; stems 3 to 6 inches long, densely- 

 branched and prostrate, very leafy, root not woody; leaves i to 2 

 inches long, including the ^-inch petiole; leaflets 4 to 8 pairs, 3 to 

 4 lines long, i to i}4 wide, oblanceolate to narrowly oval, rounded 

 at apex and acute at base, edges contiguous, softly pilose with 

 spreading hairs, as well as all the rest of the plant, even to calyx and 

 legume, but the latter rather densely long pilose; peduncles an inch 

 long, 3 to 6 flowered, and loosely so; flowers ascending, in fruit 

 horizontal, pedicel very short; calyx campanulate, a line long, teeth 

 the same and setaceous; banner abruptly reflexed at tip of calyx 

 teeth, broad, notched, white or purple, 3 lines long, erect part 2 

 lines long; purple tipped keel surpassing calyx teeth by i^ lines, 

 arched, the acute tip incurved to nearly a semicircle; wings barely 

 surpassing keel, lanceolate, entire, obtuse^; pods 6 lines long, mem- 

 branous, ovate or lanceolate, acute, sessile, when ripe incurved to 

 nearly a semicircle, cross section triangular and acute at ventral 

 suture, with rounded lobes at base, dorsal septum not intruded, but 

 dorsal sulcus always so at base of pod and to the middle; i celled, 

 no intrusion of ventral suture, but the suture is rather thick; while 

 the dorsal is inconspicuous. 



Resembles A. Parryi in habit, and is allied to A. trijiorus and A. 

 triquetrus, but quite different; clay soil, at 5,000 feet altitude, Thomp- 

 son's Springs, Eastern Utah, May 7, 1891. Dedicated to George 

 Foster Peabody. 



Astragalus Geyeri Gray. Banner oval to ovate, but sides 

 generally turned back at some angle less than 90°, then the outline 

 is oblong, slightly notched, white or very light purple, faintly purple 

 veined; white spot scarcely visible, coming within ^ a line of the 

 sides and end; banner ascending to 75°; sulcus shallow, scarcely 

 contracted at base; banner i^ lines longer than wings, and wings 

 I to i}4 lines longer than keel; blade of wings obliquely ovate, 

 obtuse, ascending 30°, i line wide; keel a line longer than calyx 

 teeth, incurved. 100°. I have doubts that it is annual, for the slender 

 roots seem to have tubers on them. Very common in gravelly or 

 light soil in the valleys and lower slopes. It blooms May to June. 



Astragalus platytropis Gray. This interesting subalpine plant 

 is found only on the high mountains, occurring as far east as the
