Crossosoma was founded by Nuttall on a specimen of 
the present species collected by Dr. W. Gambel in the 
Island of Santa Catalina, off the coast of California in 
about 33° N. lat. Much finer specimens were subsequently 
collected by Dr. E. Palmer and others in the far more 
isolated Guadalupe Island, off the coast of Lower California, 
in about 29° N. lat. A second species, CU. Biyelowit, 
S. Wats., was published in 1876, having previously been 
confused with C. californicum by Torrey, and figured as 
such. It inhabits the mountains of the mainland of Cali- 
fornia. A third species, CO. parviflora, Robins. & Fern., of 
more recent discovery, is a native of Sonora, North-west 
Mexico. 
The floral structure of Crossosoma is somewhat anoma-
