FLORA OF THE SANTA. BARBARA ISLANDS. 207 



Some of the seaward slopes of Santa Rosa Island abound 

 with Eschscholtzias varying in color from red-brown to ex- 

 tremely glaucous. The flowers are of all shades of color 

 between light yellow and deep orange, and vary much in 

 size. 



Dendromecon rigidum, Benth. =i). Harfordii, Kellogg, 

 and D. flexile, Greene. 



This shrub on Santa Kosa varies from forms having oval 

 leaves with smooth margins to those having lanceolate leaves 

 with rough margins. Sheltered from the wind it becomes 

 D. flexile, Greene, but when exposed the leaves are smaller, 

 narrower and rougher. 



Platystemon Californicus, Benth. 



Cheiranthus asper, Cham. & Schlecht. 

 Seeds slightly winged. A form in situations sheltered 

 from the wind resembles Erysimum asperum in habit. 



Erysimum insulare, Greene. 



Sisymbrium reflexum, Nutt. 



Lepidium lasiophyllum, Nutt. 



Capsella divaricata, Walp. 



Isomeris arborea, Nutt. 



Viola pedunculata, Torr. & Gray. 



Helianthemum scoparium, Nutt. 



Prostrate-spreading when growing in situations exposed 

 to the wind. 



Frankenia grandiflora, Cham. & Schlecht. 



Silene laciniata, Cav. = S. simulans, Greene. 

 Very common on both Santa Cruz and Santa Rosa Islands. 

 Plants vary from a few inches to four feet in height.
