380 CHAPARRAL. 
Arctostaphylos glauca, big-berried manzanita, is distributed in 
patches over the Coast Range. It is confined chiefly to the middle 
subzone. between 2,000 and 3,000 feet, although it grows both at 
higher and at lower elevations. It thrives upon all kinds of soil, but 
is a very slow grower, and therefore does not recover rapidly after 
burning. It reproduces by seed and coppice, and, lke the other 
manzanitas, forms a broad crown of solid wood at the surface of the 
soil, from which the roots ramify in all directions. As cover it is a 
very desirable species. 
Arctostaphylos manzanita, manzanita, is found throughout the 
chaparral region. It has the same qualities as glauca, and is there- 
fore desirable. 
Arctostaphylos tomentosa, woolly manzanita, is found along the 
coast as far south as the Cleveland National Forest, at altitudes of

from 750 to 5,000 feet. In northern California it forms part of the 
mock chaparral, and at still higher altitudes often grows in a pure 
impenetrable stand. It has the same desirable qualities as glauca. 
Artemisia californica, Wormwood, is an important part of the cover 
from Santa Barbara National Forest northward and ranges as high 
as 6,000 feet. It is undesirable, because it is low, casts little shade, 
and is inflammable. 
Ceanothus crassifotius, wild lilac. All of the ceanothi are called 
lilac, wild lilac, or mountain lilac. This species is distributed 
throughout the chaparral region, but is most common in the Santa 
Barbara National Forest and southward. Reproduction is almost 
always frcm seed, and coppice is rare. It is intolerant of shade and 
very inflammable.
