gall

± 3 cm large bud gall, covered by a mass of up to a cm long, thin, flattened, shining, curly appendages, not terminating in a bud and breaking off easily. The gall contains 10-20(50) gall chambers. The gall resembles the one of A. lucidus, but is considerably larger; young lucidus galls have a shiny, waxy surface, while cecconii galls are finely pubescent.

gall

The flowers in an inflorescence are galled, forming a semi-woody, shining, yellow or red globule with a diameter of ± 2 cm and a finely pubescent surface. Each individual gall consists of a 1 cm high cone that is attached to the centre of the globule by its tip. The gall embraces a cavity above 3-4 gall chambers. Rarely also isolated gall occur.
