On the CYNIPIDOUS GALLS of Florida (1881)

Cynips quercus clavigera n. sp.

Galls.--Abrupt, irregular, woody, tuber-like swellings, varying greatly in size, from a half to an inch and a quarter long by almost the same in width, attached to the terminal twigs and branches; externally (at the beginning of the season), it is smooth and resembles very much the gall of Cynips q batatoides, but later in the season it becomes rough with deep fissures, through which issue spiny, succulent tubes, which secrete a sticky honey-like substance; internally, at first it is white and soft but becomes brown and hard with age; the tubes are thickened at base in the centre of which the larva resides.
