BOTANY. 
There was little opportunity for investigating the flora of that portion 
of the Sierras which lies in Western Nevada, but sufficient was seen to show 
that it diifers widely from that of the mountain ranges of the Basin. The 
heavily timbered mountain sides, the well-watered caiions, the picturesque 
shores of Lake Tahoe and the snowy crown of Washoe Peak yet remain a rich 
and inviting field for the botanical collector. The species of the following 
list are mostly of Dr. C. L. Anderson's collection from near Carson City," 
and are referred to these mountains as their probal^le habitat. All are con- 
fined to California or Oregon, excepting Pentstemon Menziesii, which extends 
to the Rocky Mountains of British America. Fragaria vesca and Arcto- 
staphylos glauca should be added, also found in tlie Uintas but not in the 
intervening territory.

Southern Flora of Nevada and Utah. The region lying south of 
that embraced in the survey becomes gradually more dry and desert and the 
vegetation approaches more and more to that of Arizona and southeastern 
California. Little, however, is actually known of the flora, and . no more 
promising field Ues open to the botanist than this. The collections that have 
been made by Dr. Edward Palmer in Southern Utah and the few other species 
that could be found reported as growing within the hmits of Nevada and 
Utah are embraced in the Catalogue and given without attempt at classifica- 
tion in the following list. Some, like the Larrea^ are widely diff"used and 
abundant desert species; others are rare and confined to the mountains. 
The Anemopsis appears to be the only saline aquatic among them.
