Massai Point, Chiricahua National Monument, ~6800' elevation, Cochise County, Arizona, USA
April 29, 2011
Size: cluster 3 cm, galls 8 mm
A colleague found this cluster of spiny galls on the underside of a scrub oak leaf, which I suspect to be Netleaf Oak
(Quercus rugosa in "white oak group" of genus) [confirmation pending]. Cluster of approximately 30 galls, each 8 mm tall with ~1 mm-wide opening at peak. UPDATE on scrub oak species ID: "probably"
Quercus rugosa (in white oak group), "possibly"
Q. hypoleucoides (in red oak group).
