Hook, and Auxot, Bot. Beecliy, p. 391. Tins curious species, of which we have seen only a dried specimen, was collected in Upper California, and bears some affinity to the Q. Garri/aua. Accordinjj; to Hooker and Arnot, the leaves and whole appearance of the plant closely resemble Q. fics-sijlj/ora, but with different scales to the cup of the acorn.
