NEW SPECIES FROM THE SIERRA NEVADA 

 MOUNTAINS OF CALIFORNIA. 



BY ALICE EASTWOOD, 



Curator of the Departtnent of Botany. 



Most of the plants described below were collected on a 

 trip to the south fork of Kings River from Millwood to the 

 Kings-Kern Divide (Harrison's Pass), and to Kearsarge 

 Pass. The trail lies near the boundary of Fresno and 

 Tulare counties, and is one of the best known of the south- 

 ern Sierra Nevada. 



It is a country of magnificent forests, beautiful mountain 

 meadows, rocky slopes down which dashing torrents rush, 

 and canons through which the river flows serenely but 

 swiftly. The upper elevations are characterized by jagged 

 peaks and ridges which are clothed with everlasting snow 

 and enormous granite boulders, and are gemmed with little 

 lakes of great beauty. 



The collection was made between July 2nd and 12th, 

 1899. To the care and assistance of Messrs. Pierson Dur- 

 brow, S. L. Berry, and Benjamin Brooks, members of the 

 party, the success of the trip is due. 



The types are in the Herbarium of the California Acad- 

 emy of Sciences.
