Astragalus tegetarius var. rotundus. 



No. 5649b. July 18, 1894, Loa, Utah, 7000° alt., in 

 clay. 



No. 6002. September 6, 1894, Panguitch Lake, Utah, 

 8400° alt., in gravel. 



This has the habit of Astragalus tegetarius, but the 

 leaves are stiffer and more pungent, much after the fashion 

 of A. Kentrofhyta, but lies strictly flat -on the ground; 

 the pods are generally not in the least flattened, oval-ovate 

 and usually straight, though the immature pods are occa- 

 sionally flatfish and sometimes a little curved. 



Astragalus tegetarius var. im^lexus Canby does not 

 seem to be worthy of varietal rank as it is only a con- 

 densed form. 



This species is very close to A. Kentro-phyta, but the 

 habitat is very different, most of the differences in ap- 

 pearance can be explained by the different habitat. 



Astragalus Kentrophyta var. ungulatus. This is the 

 white hoary plant with lanceolate, curved and acuminate- 

 tipped pods with round cross-section, represented by Wat- 

 son's specimen in the National Herbarium from Monitor 

 valley, Nevada, and by mine from Sprucemont, Nevada. 

 t Astragalus cymboides. 



No. 5658q. July 21, 1894, CottrelFs Ranch, Henry

Perennial, flat and matted on the ground; peduncle 

 shorter than the leaves in flower; stipules triangular, 

 rather large, adnate, not connate, rather longer than the 

 very short nodes, densely appressed-strigose and thus giv- 

 ing the stems a shaggy appearance; leaflets 4-5 pairs.
