First published in 1950, this alphabetical glossary gives the meaning, pronunciation, and derivation of the generic, trivial, and varietal names of plants mentioned in British Floras. It should become a small but essential reference book to all users of Floras, including beginners in botany, whether students or amateurs. Intelligent, familiar, and confident use of the scientific names of plants is desirable in any serious work. This book will put it in the power of every reader, whether trained in Latin and Greek or not, to speak and write and understand the international names of British plants. This third edition contains the names of further plants and entries listed in the second edition of the Flora of the British Isles, edited by Clapham, Tutin and Warburg, and also incorporates a number of corrections to earlier editions of the Glossary.
