Willis's Dictionary is a famous publication in the world of botany and horticulture. It is a comprehensive and indispensable reference to the generic and family names of flowering plants and ferns. The entries attempt to cover all published generic names from 1753 onwards and published family names from 1789, together with a number of supra- and infra-familial taxa where these have not been based on family or generic names. The generic names include many variant spellings and inter-generic hybrids. Brief characters of subfamilies are usually given. The treatment of the families and higher taxa of the Pteridophyta is based on the classification scheme proposed by Pichi-Sermolli. The synopses of the Bentham & Hooker and Engler & Prand systems are retained. This eighth edition is now published in paperback in order to make it available to a wider readership, not only of professional botanists, but also students and serious amateurs.Willis, J. C. is the author of 'Dictionary of the Flowering Plants and Ferns' with ISBN 9780521313957 and ISBN 0521313953.
