gall

Gall in a male catkin, but not consisting of a galled stamen, rather derived from the flower base (Buhr(. It is oval, c. 1.5 mm long, green at first, eventually brown. The gall is smooth, not ribbed, no hairs, except for a small tuft at the tip that may be present. Gall often surrounded by unmodified stamens.
Buhr, Redfern, and Melika describe the gall as warty; that is in disagreement with Adler’s own description. Houard (1908a) depicts an indeed smooth, but apically distinctly acute gall.
