Abstract
The plant gall as ordinarily defined consists of deformed, usually swollen tissue and is the result of a large increase in the number of plant cells. We are concerned with the galls produced by mites and insects. They occur in innumerable variations upon a great many different species of plants and result from the effects of the producers upon adjacent plant cells and a reciprocal development of the affected tissues. It is well to note at the outset that a number of species closely related to gall producers develop in plant tissues without causing apparent galls or deformities, e. g., Aulacidea and allies and individual species of typically gall producing forms, such as Andricus cryptus Ashm.
