Collections were made as follows: 



Sporobolus cryptandrus, var. strictus. 



Common, but only eaten when young. I have noted it at every 

 stop from Ogden to this point, and have rarely found a plant 

 which had been touched by stock, even where other grasses 

 were eaten closely. 

 Sporobo his airoides . 



Common in valleys throughout Utah, but eaten only when young, 

 and not valued for hay. 

 Sporobolus asperifolius. 



Very common. 

 Agropyrum glaucum (Blue-grass, blue-stem). 



Quite common and regarded as the best native species. Grows 

 sometimes 4 feet high. It is abundant from here to Denver. 

 Bouteloua polystachya, var. 



A few plants seen in cultivated ground. 

 Munroa squarrosa. 



Common, but not eaten by stock. Also seen at Denver. 

 Panicum capillare, var. 



Common. 

 Panicum crus-galli, var. 



Several of the more common forms are abundant on the river- 

 bank. 

 Agrostis vulgaris. 



Rather common in irrigated land. 

 Sch edo nnardus Texanus. 



Common and eaten well in spring, but worthless after becoming 

 dry. 



Atriplex canescens (Shad-scale). 



Perhaps the most important forage plant here after frost. 

 J uncus nodosus, var. megacephalus. 



Said to be eaten well, especially by horses.
