Erodium cicutarium (Filaree). 
‘ery highly prized. People here inform me 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). 
e 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 Record, informs me that it is even more common 
about Denver than here. 
Melilotus alba. 
Jommon 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. 
Trifolium involucratum. 
Very abundant on wet ground. Fouad everywhere along streams, 
but more common here than elsewhere. 
pisos tridentatum. 
nmon on ditch banks, and eaten closely. 
Carex siccata ? 
ery common on lowlands, where it is.cut for hay. It is eaten 
fairly well. 
Several speces of Cyperus, Scirpus, and Carex grow on low grounds 
and are called  ‘vater-grass ;” although they are not valued as highly 
as the grasses, these sedges few 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. 
Wadsworth, Nevada, July 21. 
Wadsworth is on 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, 
Keleria, Bromus, and a large proportion of sedges or “ water-grasses,” 
as they are termed here. Collections were made here as follows: 
Agrostis exarata, var. 
Comm 
Poa levis. 
Oceasionally found on low eee
