The Plant-Book Plastic cover: A Portable Dictionary of the Higher Plants by David Mabberley
This comprehensive portable dictionary describes flowering plants--conifers and their allies, and ferns and their allies--with their common names and uses. It sets out to fill the gap formerly filled by the early editions of Willis's Dictionary of the Flowering Plants and Ferns, and is based largely along the lines of that work, although with more references and common names, the whole being arranged according to Cronquist's system.
