FLORA OF THE SANTA BARBARA ISLANDS. 209 



LupiNUs Chamissonis, Escli. 



LupiNDS MiCRANTHUs, Dougl. = L. uiiibellatus, Greene. 



The plants are slightly more spicate than those of Santa, 

 Craz Island, and the mainland plants are not different from 

 those of both Islands. 



Trifolium trident atum, Lindl. 



Astragalus leucopsis, Torr. & Gray. 



Astragalus Miguelensis, Greene. 



Very abundant in some localities. It is probably a vari- 

 ety of A. leucopsis. 



Melilotus parviflora, Desf. 



Prunus ilicifolius, Walp., var. occidentalis (Lyon). 

 = P. occidentalis, Lyon. 



On Santa Eosa Island it is confined to the bottom of the 

 canons, and is much larger and more tree-like than on Santa 

 Cruz Island On Santa Cruz it sends up several trunks 

 from one root and resembles a big bush, but on Santa Rosa 

 a single trunk ascends sometimes fifteen feet before it be- 

 gins to branch. The leaves are generally more or less sin- 

 uate-dentate and sometimes entire. In the Santa Inez 

 Mountains, near Santa Barbara, the leaves sometimes have 

 entire margins and it becomes six inches in diameter and 

 attains a height of fifteen feet. A large specimen near San 

 Francisco has a diameter of more than two feet. 



RuBUS URSiNus, Cham. & Schlecht. 



Adenostoma fasciculatum, Hook. & Arn. 

 Spreading-prostrate in situations exposed to the wind. 



Rosa Californica, Cham. & Schlecht. 

 Heteromeles arbutifolia, Roemer.
