Erodium cicutarium (Filaree). 



Very highly prized. People here inform ine that they have fre- 

 quent requests for seed to be sent to localities where it has not 

 been introduced. It is becoming more abundant here every 

 year. 

 Medicago sativa (Alfalfa). 



The plant here is affected with a species of fungus (Phacidium 

 medicaginis, Lasch.), the specimen sent being no worse than a 

 fair sample of most fields, not only here but wherever I have 

 seen alfalfa. The farmers make no complaint of it; in fact no 

 one seemed to have noticed it. Mr. Davis, the editor of the 

 Live Stock Eecord, informs me that it is even more common 

 about Denver than here. 

 Melilotus alba. 



Common throughout Utah and Nevada on low ground, and used 

 considerably for pasture. It is almost the only plant in some 

 fields about Salt Lake City. 

 Trifoliu m invo lucratum . 



Very abundant on wet ground. Found everywhere along streams, 

 but more common here than elsewhere. 

 Trifoliu m tridentatum . 



Common on ditch banks, and eaten closely. 

 Carex siccata f 



Very common on lowlands, where it is cut for hay. It is eaten 

 fairly well. 



Several species of Cyperus, Scirjms, and Carex grow on low grounds 

 and are called *• water-grass;" although they are not valued as highly 

 as the grasses, the?e sedges form an important part of the pastures, and 

 are eaten closely in the absence of other feed. Some meadows which 

 are cut for hay are at least three-fourths covered with these. 



Wads worth, Nevada, July 21. 



Wadsworth is ou the Truckee River. The valley here is narrow and 

 surrounded by high, barren, treeless hills, which have a scattering 

 growth of sage-brush and grease-wood, with but little grass. Alfalfa 

 is the main crop, though redtop is very common in the few cultivated 

 fields. The native meadows along the river contain species of Agrostis, 

 Koeleria, Bromus, and a large proportion of sedges or " water-grasses," 

 as they are termed here. Collections were made here as follows: 



Agrostis exarata, var. 



Common. 

 Poa kevis. 



Occasionally found on low ground.
