other genus is Hazardia — shrubs of the order of Compositse 

 in some respects intermediate between the Australian 

 shrubby asters and the Californian genus Corethrogyne 

 Two of the species of Hazardia belong to Santa Cruz ex- 

 clusively, and the third is of that remote and isolated island 

 not belonging to this group, Guadalupe. 



The most interesting of all our insular plants to me are 

 the Lavateras, of which I could, however, find no trace on 

 Santa Cruz. But they ought to be named in this connec- 

 tion, furnishing as they surely do, one of the most suggest- 

 ing hints that our little archipelago may actually have been 

 connected with some other continent than ours. Of Lava- 

 tera there are some eighteen or twenty species in various 

 parts of the Old World, and there is one in Australia. On 

 our American continent we have not one ; but the little 

 islands which lie off our southern coasts have already yielded 

 four indigenous and quite peculiar species of this genus. 

 One of these foui inhabits Guadalupe: the second, San 

 Benito, a cluster of rocky islets not far off the Lower Cali- 

 fornia peninsula, and nearly east of Guadalupe: the third 

 is peculiar to the Coronados Islands, which lie in sight of 

 San Diego: the fourth has been found on two or three 

 members of the Santa Barbara archipelago. This is, I re- 

 peat, the most marvelous fact which I am acquainted with in 

 connection with Pacific North American botany; and it is 

 one which strongly pleads for further exploration and study 

 of these inviting insular fields.
