CHAPARRAL. ol 
Ceanothus cuneatus, Nuttall’s ceanothus (fig. 3), is distributed 
throughout the chaparral region, but is most common in the northern 
areas, where it ranges up to 5,000 feet. It is from 3 to 12 feet high, 
and though almost impenetrable to man, seldom makes a continuous 
cover. 
Ceanothus divaricatus, deer brush, is distributed over the entire 
chaparral area below an elevation of 7,000 feet and is an important 
part of the cover, particularly in the Angeles National Forest. How- 
ever, it is not desirable. 
Ceanothus papillosus, deerweed, is found only north of the Santa 
Maria River, but is an important part of the cover in the Monterey 
National Forest. It is low, inflammable, and undesirable.

Fic. 3.—Lilac, Ceanothus cuneatus, 7 feet high. 
Ceanothus sorediatus, buckthorn, is represented throughout the 
Coast Range and in the Sierra Nevada and forms an important com- 
ponent part of the chaparral on some watersheds in the Santa Barbara 
National Forest. It reproduces wel! on burned-over areas and pro- 
duces vigorous coppice after burning. Its branches are armed with 
spines, and a pure stand is impenetrable. Although it attains a 
height of 10 feet, and in some cases assumes a tree form, its leaves are 
small and widely distributed, giving only a meager shade. On the 
whole, it is an undesirable species. 
Cercocarpus parvifolius, mountain mahogany. There are several 
recognized varieties of this species, one of which, betulaefolius, is 
found in the chaparral region and northward along the Coast Range
