I have listed something over 100 species of grasses collected. These 
collections were made mostly on four trips made in this region. Some 
collecting was done in 1898 and 1899. For verification of the identifi- 
cation of species I am indebted to various members of the former Di- 
vision of Agrostology. Owing to the many changes in nomenclature, 
the names are not the same always as now recognized. The collections 
'were made between the years 1898, 1899, 1900, 1901, 1902, 1908. 
The Uintah Mountains are important sources for the water supply 
of the irrigated districts of Utah. Such streams as the Weber, Provo, 
Bear, Black’s Fork, the Duchesne and the several branches of the Lake 
Fork have their sources in the high, snow capped peaks of the Uintah 
Mountains. Such rugged peaks as La Motte, Wilson, Gilbert, Watson, 
Emmons, Bald, and Mt. Agassiz are snow capped for much of the year. 
Black’s Fork, Henry’s Creek, Sheep Creek, Burnt Fork, Weber, Smith’s 
Fork, and Bear River come from the north side of the range, while 
the Duchesne with its branches, Lake Fork, Uintah River, Brush Creek, 
come from the south side of the range. There are numerous lakes, but 
all are small. Kamas is situated on what is commonly called a prairie, 
an ancient fresh water lake of considerable size. Evanston, Lower Black’s 
Fork, Myer’s Ranch, Burnt Fork, are in Wyoming, the remaining lo- 
calities in Utah. In the list more numbers are recorded from the north 
side of the range because it represents the work of four seasons of 
collecting. 
The collectors will be referred to by letters*, the altitude by the num- 
ber preceding the collector’s letter. 
PHALARIDEAE. 
Hierochloe odorata (L.) Wahlenb. 
This boreal grass is distributed across the United States and in the 
mountain regions of the Rockies, also Europe; common in northern 
Iowa. Sometimes forms a considerable part of the herbage in meadows. 
Associated with such plants as Pedicularis groenlandica, Erigeron and 
Pentstemon.
