is clearly not that plant, and differs from g/areosus in having a 2- 
celled -pod that is 1 celled at apex only, the flowers also are cream 
_ white, and not ‘‘blue,’’ indistinctly purple veined. Pods long, 1 to 2 
inches, acuminate, lanceolate, fleshy when green, much compressed, 
2 celled by the intrusion of the dorsal sulcus long-appressed_ hairy, 
often su!cate both dorsally and ventrally, dorsal sulcus very: deep; 
banner extending 4 lines beyond the calyx teeth, slightly and gently 
arched, notched, sides reflexed at base only, 2 lines longer than the 
blunt, incurved and purple-tipped keel; sulcus deep, semi cylindric, 
wings linear, a little longer than the keel, horizontal at tip; calyx cylin- 
_ drical, 5 lines long; teeth subulate, a line long or more, nigrescent 
peduncles 2 inches long, shorter than the leaves and prostrate in 
fruit except in the shade, leaflets narrowly lanceolate to narrowly 
oval, 3 to 5 lines long and 1 to 2 wide; whole plant coarsely silky 
pubescent with appressed hairs; stemless, not at all woolly. It 
grows under sagebrush in the valleys or lower hillsides and is quite 
distinct from any other species that I know. It flowers early in May. 
AsTRaGALuS UraHensis, T. & G. Though it is difficult to al- 
ways separate this from A. eriocarpus, and less so from A, Purshii 
in the herbarium, yet it is not at all so in the field, since A. 
eriocarpus flowers at least a month earlier than A. Ufshensis and is 
out of b.oom before the other blooms. 4. Purshiz blooms as early 
or earlier than A. evzocarpus and is a high altitude plant, 7. e., does 
not grow in the valleys, the home of the other two species, though 
the latter sometimes go up to 7,000 feet altitude. In 4. Purshii the 
pubescence of the leaves is quite different, while the matted habit 
and narrow leaves and short woolly pods distinguish it at all times. 
It would certainly be considered a hybrid from the other two if they 
grew together with it but they never do. 
In A. Utahensis the banner is oval as one looks at it in the flower, 
rather deeply notched, white spot broadly cuneate, tridentate or _ 
with a single acuminate tooth from the center of the rounded or 
truncate apex, sides of white spot beautifully veined with narrow. 
nearly parallel purple lines running down to the base; banner bril- 
liant pink purple; wings linear, 2% lines longer than keel, slightly 
enlarged at tip, rounded or almost truncate, straight, purple through- 
out; tip of keel dark purple. This is one of the handsomest flowers 
in the West, but though very common in Central Utah seems to be- 
come less so westward.
