lized. It ranges from Bandon, Oregon, southward to Santa Bar- 

 bara and Santa Cruz Island, California. The genus Eriophyllum 

 ranges from British Columbia to Baja California and eastward 

 to Montana, Wyoming, Nevada, and Sonora. Two-thirds of the 

 species are confined to the California Coast Ranges and the lower 

 altitudes of the Sierras (Rydberg, 1915). 



Subordinates— Nemacaulis denudata Nutt. (fig. 8/) is an un- 

 important annual herb which grows in semistabilized sand 

 along the coast from San Pedro, Los Angeles County, south into 

 Baja California. The record farthest south is from San Jorge, 

 N Lat. 26°. It is also found inland in southwestern Los Angeles 

 County, along the western edge of the Colorado Desert, and in 

 southwestern Arizona. The genus is monotypic. 



Mucronea californica Benth. (fig. 8^) and Chorizanthe pun- 

 gens Benth. (fig. 8/2) are small annuals which cover extensive 

 areas of stable sand where the shrubs grow sparsely. Chori- 

 zanthe has the more northerly range and is more closely confined 

 to the coast. It is found from Bodega Point, Sonoma County, 

 southward to Point Conception. The range of Mucronea slightly 

 overlaps that of Chorizanthe; it extends from Morro, San Luis 

 Obispo County, soudiward to the Mexican boundary and inland 

 to the upper Salinas Valley and the San Bernardino Valley. The 

 genus Chorizanthe occurs in western North America and in 

 northern Chile west of the Andes (Reiche, 1907; Goodman, 

 1934). In North America it is mainly typical of the deserts and 

 arid foothills of southern California. The small genus Mucronea 

 seems to center in southern California. 



Eriogonum latifolium Sm. (fig. 8/) often precedes the shrubs 

 on recently stabilized sand. It is stricdy littoral, ranging from 

 Point St. George, Del Norte County, southward to Point Sur, 

 Monterey County.
