Plant galls is an identification guide to plant galls in Britain and Ireland.
A plant gall is an abnormal growth of plant tissues. A plant produces this abnormal growth under the influence of another organism. Galls provide shelter and nutrients for the invading organism. Well known plant galls include oak apples, witch’s brooms and robin’s pincushions.
Gall causers include fungi and invertebrates, such as aphids, mites, gall-wasps and sawflies. Plant galls occur almost anywhere that plants grow. They occur on the stems, leaves, flowers, fruits, seeds and roots of plants. A good list of different plant galls can be made in a domestic garden, particularly where there are mature trees or wild flowers. Oaks and willows are particularly rich in galls.
The publication of the first edition of British Plant Galls in 2002, building on an earlier guide in 1986, stimulated more interest in plant galls. This fully revised second edition includes new and expanded keys to incorporate changes in nomenclature which have accumulated since 2002. Additional galls have been illustrated and many figures replaced, with new drawings based on British specimens.
