Description
Galls are distinctive swellings or abnormal growths of plant tissue caused by an attack of a living organism. Insects, mites, nematodes, bacteria, fungi, and viruses can trigger these plant deformities. Galls can also form as a result of mechanical injury. This publication deals only with tree and shrub galls caused by insects and mites.
