 Carex variabilis Bailey (?). — A slender, erect form usually found in the margins of

 Carex variabilis elatior Bailey. — A bunch sedge of the most pronouuced sort, so 



tufted that it can scarcely he broken up, leaves abundant and stems fruiting 



freely, 20 to 30 inches higli. Probably of small economic value. Woods Creek,

 Carex eleocharis I>ailey (?). — Filiform stems and leaves from tiiberous root-stocks,

OTHER FORAGE PLANTS. 



Besides the grass-like plants given in the preceding list there are 

 many in the region designated the summer range, that furnish much 

 browsing during the summer months, but these need not be mentioned 

 in detail here. It is sufficient to call attention to the following as 

 among the more important: 



First in importance are Legriminosce, which throughout the entire 

 range are abundaiitly represented. Species of Astragalus abound 

 everywhere and many of tlieni are freely eaten. In view of the fact 

 that some {Astragalus nioUissimus, etc.) have reputed poisonous proper- 

 ties, it is a question yet to be solved how generally they may be 

 accepted as forage plants. Species of Thermopsis, abundant in some 

 localities, are not without suspicion of having injurious properties. 

 Among the legumes that pass unchallenged may be named the clovers 

 {Trifolium longipes ^STutt., and other species) and Hedysarum (//. ameri- 

 canum liritt. and H. mackcnzii Kich.), all of which are of frequent occur- 

 rence and in some localities abundant. These are greatly relislied by 

 stock and furnish an important part of the pasture. 



In the eastern i>art of the State another genus that is particularly 

 well represented is Psoralea, the following species being abundant: P. 

 laneeolata Pursh, P. UnearifoUa T. & G., and P. temiiftora Pnrsh. Of 

 the valne of these species the writer can not speak for he does uot even 

 know that stock feed upon them. 



Attention may be called to the following list, the plants of which are 

 abundant in the summer range as well as in the desert. (For more or 

 less conq)lete notes ui)on their economic value see the JJed Desert list 

 (l). li4) in which they have been individually considered.) 



Astragalus. Chenopodium. 



Liipinus. Sarcobatns. 



Vicia, Sueda. 



Atriplex. Eriogonum. 



Eurotia lanata. Artemisia.
