 Lslands off coast of S. California. Dr. Ktllogg's sjtecies sa* originally collected on S;mta 

 Rosa Isl. is said to be a low shrub, but tlie foliage shows no constant or witisfactory 

 differences from the arborescent D. Jifirilis, Greene, of Santa Cruz Isl. Ksscntially the 

 same plant has been collected upon Santa Catalina Isl., Brandei/ee. All these insular forms 

 are unsatisfactorily separable from each other and none too definitely distinguiHlied from 

 broad-leaved forms of the mainland, such as Ilartweg's 1C41. (See T. S. Brandegee, 

 Zoe, i. 46.)
