The chief aim of this book is the reconstruction of the processes and events that have determined the present flora and vegetation of the British Isles, first of all through the long ages when natural conditions prevailed and cycles of glaciations and recessions and slow geological processes were in charge, and afterwards through the nearer and much shorter span of time during which, from the Neolithic onwards, human interference has progressively and severely altered the scene. This is an exercise in biogeography that Darwin called 'that grand subject, that almost keystone to the laws of nature'. But instead of adopting Darwin's conjectural approach, based largely on circumstantial evidence, what this 1975 second edition achieves is a factual reconstruction of events by records of the actual presence of individual species or genera, in large numbers, at particular sites and specified times through the geological and historic record.

New Flora of the British Isles is the standard work on British plant identification. It is designed to be user-friendly, serving as a practical database for taxonomists, ecologists, conservationists, plant geographers, teachers and students, as well as for amateur botanists and plant hunters. The Flora includes all native, naturalised and crop plants, and all recurrent casuals. Over 150 pages of specially prepared illustrations are provided to aid identification of critical groups and less familiar alien taxa. Technical terms are kept to an essential minimum. In this new edition the text has been revised thoroughly throughout and adjustments made to many of the illustrations to ensure that the work is fully up-to-date. Over 200 species and subspecies have been added, together with numerous extra hybrids, bringing the total number of taxa covered to over 4500.

Following rigorous testing throughout Britain and Ireland over the last 10 years, this second edition is a much revised version with re-written keys, additional species, phenology and, of course, many new novel identification characters. A few new illustrations have been added where space allows. In addition, the nomenclature has been updated in line with modern taxonomy. Each key has been carefully reviewed and revamped so this version aims to be quicker and more comprehensive in detail than its predecessor, greatly improving on the original work. Additional floral and fruiting characters have been added for some of the more difficult species making it more handy for casual field use.
