CALIFORNIA. 55 
This species was considered by Hooker and Arnott (Bot. Beech. p- 160 and 
390) as the same as the P. occidentalis from the United States, commonly culti- 
vated in Europe as the occidental plane, but the leaves of the latter, whether wild 
or cultivated, are but slightly lobed and bordered with large irregular teeth be- 
tween the lobes, the young leaves are much less woolly, and the Styles very 
short.

190. Myrica Gale, Linn.—The leaves in these specimens are larger, and the growth of the 
whole branches more vigorous than is usual in the European plant, but I can perceive no other 
difference.—San Francisco. 
191. Quercus agrifolia, Nee.—Hook. Ic. Pl. t. 377.—San Francisco. 
192. Quercus Douglasii, Hook.? Ic. Pl. t.383.—San Francisco.—A very imperfect specimen, 
which may possibly belong rather to the following species. 
193. Quercus Hindsii, sp. n., foliis submembranaceis petiolatis obovato-oblongis basi acutis 
profunde pinnatifidis supra glabris subtus pallidis glabris puberulisve, lobis obovatis oblongisve ob- 
tusis sinnatis, fructibus subsessilibus solitariis paucisve, cupula hemispherica dense squamosa, 
squamis ovatis convexis breviter appendiculatis, glandula elongata oblonga subacuminata cupulam 
3-4-plo superante obtusa cum umbone parvo conico.—San Francisco. 
This oak is near to the Q. Douglasii, but the leaves are much deeper divided, 
especially those of the sterile branches, which are much like the leaves of some 
varieties of the common hawthorn; and the form of the acorn is very remarkable. 
It is usually from 1} to 2 inches long, and scarcely half an inch in diameter in its 
thickest part. There are some branches without fruit which have the leaves yet 
more divided, and others with the leaves perfectly smooth underneath, but all are 
apparently forms of one species.
