Hook. Ic. ined. Hook, and Arnot, Botany of Beechy’s 
Voyage, p. 391. 
This curious species, of which we have seen only a 
dried specimen, was collected in Upper California, and 
bears some affinity to the Q. Garryana . According to 
Hooker and Arnot, the leaves and whole appearance of 
the plant closely resemble Q. sessiliflora , but with differ- 
ent scales to the cup of the acorn. The leaves appear 
to be smaller, narrower, and less deeply divided than in 
Q. Garryana. The young leaves are covered with 
down on both sides, and the lobes tipped with short, 
soft, acute points. 
To us, the branch which we have seen bears some 
resemblance, though vague, to the Post Oak, ( Q. stel- 
lata .) The cup and acorn is also somewhat similar, but 
larger, while the leaf is smaller and scarcely dilated 
above. The under surface is covered with the same 
stellated pubescence, The stigmas of the fertile flowers 
are from 3 to 5 in number.
