Up to the present time these three forms of galls have been considered as... quite distinct species on account of their dis- similarity, two of them being smooth and the other more or less profusely covered with fleshy spines. But a careful study of the architects of these forms forces the conclusion that they are identical, there being no tangible characters by which to separate them. The spiny form of gall always grows upon trees with pubescent leaves^ such as Hicoria tomentosa^ while the smooth forms are always found upon trees with smooth leaves, such as Hicoria glabra, amara and probably other species.
