FOUQUIERACE/rl

 Carrissa creek, California ; December 10, in flower. 



A widely diffused species, being found from the San Pedro, in Western Texas, 

 to near the Pacific ocean. Mr. Thurber, of the Mexican boundary survey, found 

 F. spinosa, near Rayon, in Sonora, and I have what appears to be F.formosa col- 

 lected by Mr. Rich, in Lower California. It strongly resembles F. splendens, 

 except in the looser inflorescence, and the spines are an inch long ; while in 

 Kunth's description of F.formosa they are said to be " brevissimis." In Phila- 

 teria horrida, Liebm., however, (which is pretty certainly the same species,) the 

 species are described as from half to two-thirds of an inch long. Liebmann, with- 

 out being aware that his Philazteria was a Fouquiera, referred the plant to Pole- 

 moniaceiK, and long before Willdeman considered F. spinosa as a species of Cantua; 

 so that several botanists have noticed the resemblance of Fouquiera to Polemo- 

 niacen.
