Cynips (Q. Californica, n. sp.

Galls: Polythalamous, sessile on the branches of the Californian White Oak (Quercus Hindsii ?) Sub-globular, but varying much in form and size. A common form is what may be termed balloon-shaped, the upper part perfectly globular, the lower tapering more or less to the sessile base. They often occur of a long compressed oval form: these are placed longitudinally on the branch and the length is two or three times their breadth or thickness.
