ASTRAGALUS PEABODIANUS n. sp. Inflati. Perennial, matted 
ceespitose from a branching root; stems 3 to 6 inches long, densely 
branched and prostrate, very leafy, root not woody; leaves 1 to 2 
inches long, including the }2-inch petiole; leaflets 4 to 8 pairs, 3 to 
4 lines long, 1 to 11% 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 to6 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 1% 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; 1 celled, 
no intrusion of ventral suture, but the suture is rather thick, while 
the dorsal is inconspicuous. 
Resembles 4. Parryi in habit, and is allied to 4. triflorus 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 GEVERI Gray. Banner oval to ovate, but sides 
generally turned back at some angle less than go°, then the outline 
is oblong, slightly notched, white or very light purple. faintly purple 
veined; white spot scarcely visible,,coming within 1% a line of the 
sides and end; banner ascending to 75°; sulcus shallow, scarcely — 
contracted at base; banner 1% lines longer than wings, and wings 
1 to 1% lines longer than keel; blade of wings obliquely ovate, 
obtuse, ascending 30°, 1 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
