^j 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 differs widely from that of the mountain ranges of the Basin. The 

 heavily timbered mountain sides, the well-watered canons, 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 

 Hst are mostly of Dr. C. L. Anderson's collection from " near Carson City," 

 and are referred to these mountains as their probable habitat. All are con- 

 fined to Cahfomia 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 the 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 lies 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 limits 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 diifused and 

 abundant desert species ; others are rare and confined to the mountains. 

 The Anemopsis appears to be the only saline aquatic among them.
