of chemisal, open grassy slopes, mountain meadows with small patches of 
redwood in canyons or on cool slopes. Snow Mountain east of the San Hedrin 
Mountain has its upper slopes and dry valleys covered with forests of Zibo- 
cedrus, Pseudotsuga, Pinus Feffreyi surrounded by thickets of Prunus emargi- 
nalus, Ceanothus cordulatus and as herbs Gilia aggregata, Spraguea umbellata, 
Eriogonum umbellatum with E. ovalifolium and E. Lobbii. 
The plants of the Sierra Nevada Mountains found growing in the Coast 
tanges differ somewhat, in most cases, a difference easily explained by their 
isolation and difference of situation '). i 
A comparison of the species of the genus Ribes”) richly represented in 
California brings out the fact that the separation of the two mountain systems 
by the great valley is sufficient to produce forms different enough to entitle 
them to rank as distinct species.
