is clearly not that plant, and differs from glareosus in having a 2- 

 celled pod that is i celled at apex only, the flowers also are cream 

 white, and not "blue," indistinctly purple veined. Pods long, i 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 i 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 Utahensis, T. & G. Though it is difficult to al- 

 ways separate this from A. eriocarpiis, 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. Utxhe7isis and is 

 out of b. 00m before the other blooms. A. Purshii blooms as early 

 or earlier than A. eriocarpus and is a high altitude plant, /. 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 A. 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. Utahe7isis 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, 2^1-2 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.
