Neuroterus quercicola variety pacificus bisexual form pacificus

GALL. — Typical for the species, varying as to its location on leaf veins, petioles, young stems, or flower stems, this location apparently determined by the species of the host, as follows:

Q. Douglasii Gall: Elongate swelling of a leaf vein, involving the blade; up to 25. mm. in length and 10. mm. in diameter, somewhat irregular, protruding largely from the under surface of the leaf, smooth, green, succulent when fresh, drying dark brown, rather hard and papery, without much shrivelling (fig. 60).

RANGE. — California: Cupertino, San Jose (Fullaway); Stanford University, Sunol (McCracken) ; Metz (in coll. Univ. Calif.) ; Mt. Diablo (F. A. Leach coll.); Zelzah, Gilroy (Redwood School), Coalinga (Al-calde), Three Rivers, Exeter, Paso Robles, San Luis Obispo, Byron, Galt, Redding. Certainly thruout Central California and possibly wherever Q. Douglasii and Q. lobata occur.
