But the genus Saviniona, the species of which are all 

 insular, and are trees and shrubs rather than herbs, is sup- 

 ported well in the rank of a genus. The first species of this 

 group to be discovered is endemic in the Canary Islands ; and 

 it is a very strange thing to record, that the eight other species 

 known belong to islands lying not so very far off the coasts of 

 California and Mexico. 



I subjoin the original characterization of Saviniona, for 

 the work on Canary Island botany in which it was published 

 is rarely available to students of West American botany.
