Description. —A tree of medium size; leaves deeply sinuate, three principal lobes on either 
side, which terminate in several acute points, glabrous above and below. Fruit solitary or 
clustered, nearly sessile, gland roundisli-ovoid, or, more commonly, elliptical, terminating in 
an accute projecting point, greenish brown in color, 1 to inch long, cup hemispherical, covered 
with elongated acute scales. 
This oak is found in different parts of California, hut, apparently, does not extend northward 
beyond the Oregon line. I have specimens collected both south and north of San Francisco, in 
the coast mountains, and we found it occurring in considerable numbers between Fort Reading 
and Lassen’s butte, on the western slope of the Sierra Nevada, in northern California. Where 
we observed it, it forms a tree of small, or, at most, moderate size, and of a straggling, irregular 
growth. About McCumber’s it is the only deciduous tree growing in the pine forest. 
Its resemblance to Q. tinctoria and to Q. coccinea of the eastern States is striking, but it is 
difficult to say to which it is most closely allied. The leaves are smoother and the lobes more 
acute than is usual with those of Q. tinctoria; in these respects more resembling Q. coccinea. 
In the general aspect of the trunk and bark it is, however, more like Q. tinctoria. 
The fruit is much larger and generally of a different form from that of either of the allied 
species, the acorn being frequently more than an inch in length by ■§ of an inch in diameter ; 
when fully grown they are rather cylindrical than ovoid, uniformly rounded at the ends, and 
with a prominent point at the summit. The cup is hemispherical, covered with ovoid acute 
scales. 
The differences of habit from the eastern species which it exhibits, as well as the differences of 
leaves and fruit, lead me to regard it as distinct; and I have dedicated it to my friend Dr. A. 
Kellogg, of San Francisco, who is devoting himself with so much industry and success to the 
study of the plants of his adopted State.
