242 Utah Plants. [ZOE 
4 inches long, petiole grooved, 1 to 2 inches long; leaflets 4 to 6 
pairs, narrowly to oblong-linear, acute or apiculate, greener than 
the rest of the plant, 1 to 1% lines long; spikes shoit and very 
dense, 1 to 2 inches long, erect; flowers almost sessile; bracts as 
long as the calyx and lobes, subulate ‘lanceolate, green but with a 
few scattered, long, spreading hairs on the back, and with many on 
the edge; calyx short-campanulate, less than 2 lines long; lobes 4 
lines long, subulate from a broad base, calyx white with very long 
appressed hairs, which toward the top and on the lobes are widely 
spreading, flat and twisted, and with a pustulate base, making the 
calyx lobes resemble the sepals of some shaggy species of Krynitz- 
kia—the hairs are, however, soft; corolla short; keel purple-tipped, 
about equaling the calyx lobes; wings a line longer; the banner 2 
lines longer, purple, broad, dark-siriate toward the top; pod strictly 
sessile, white with long appressed hairs, ovate or oval, scarcely 
equaling the calyx lobes, blunt but apiculate, obcompressed till the 
cross-section at base is almost linear, dorsal suture being deeply im- 
pressed at base, and very prominent toward the tip, pod flat on the 
bottom and ventral sutute inconspicuous, pod 1-celled. The spikes 
resemble some species of Oxytropis, but the keel is very blunt and 
short. This plant differs from A. flavus in the shaggy calyx, purple 
flowers, short sessile pods, and long calyx lobes. 
May 9, 1890, at Green River, Utah, on clayey soil. 
ASTRAGALUS CONFERTIFORUS Gray, was improperly raised to 
specific rank by Dr. Gray. It should remain as the var. candicans 
Gray of A. flavus, for I have abundant specimens with the light yel- 
low flowers of 4. flavus and a varying pod connecting it with A. 
flavus. June 2, 1890, at Cisco, Eastern Utah. 
ASTRAGALUS WarpDI Gray, is a good species, and is perennial 
and not annual. I collected it near where Ward found it, at Pan- 
guitch, Uiah, on June 24, 1890. It grows on gravelly soil. 
ASTRAGALUS SILERANUS. Perennial; stems many, 2 to 3 feet 
high, weak, straggling upward among the bushes like Vicia Amer- 
icana; whole plant whitened with hairs standing straight out from 
the surface of the leaves, etc.; nodes long; leaves 3 to 4 inches long, 
with a very short (% inch) petiole; leaflets about 9 pairs, about 8 
lines long, oblanceolate or oblong, with a contracted base and a 
generally deeply notched apex, sometimes truncate; stipules trian-
