localities. It ranges from Mendocino County southward through the 

 Coast Ranges to Lower California, and is also found in the foothills of 

 the Sierra Nevada. 



This shrub, on account of its low habit of growth, is particularly 

 adapted to browsing, and is one of the best for sheep and goats. Cattle, 

 however, dislike it on account of its harsh, spinescent leaves, but feed on 

 it during the winter when snow has covered the ground, or when from 

 any cause other food is not available. 



PLATE IV. QUERCUS DUMOSA, VAR. BULLATA. (CURL-LEAF SCRUB OAK.) 



CURL-LEAP SCRUB OAK (Quercus dumosa, var. bullata). 



The Curl-leaf Scrub Oak is a variety with the same habit of growth 

 as the typical species. The leaves differ, however, in having the mar- 

 gins strongly revolute, thus presenting a curled appearance. The under 

 side of the leaf is densely tomentose, and the whole leaf is thicker and 

 rounder than that of the type. The acorns of the variety are similar in 

 size and shape to those of the other, but are contained in even shallower 

 cups.
