Planned in five volumes, this critical flora provides a definitive account of the native species, naturalised species, frequent garden escapes and casuals found in the British Isles. Full keys and descriptions will enable the user to name all plants occurring in the wild, plus some ornamental trees and shrubs. For the first time, detailed accounts of all the large apomictic genera are given and many infraspecific variants included. Each species entry begins with the accepted Latin name, synonyms and the common English name. A detailed description follows, including information on flowering period, pollination and chromosome number. Separate descriptions are given for infraspecific taxa. Information on the status, ecology and distribution (including worldwide distribution) of the species and infraspecific taxa is also given. Clear black and white line drawings illustrate an extensive glossary and also illuminate the diagnostic features in a number of groups of plants.

Peter Sell (1929-2013) joined the Herbarium in the University of Cambridge's Plant Science Department in 1944, holding the post of Assistant Curator from 1972 until his retirement in 1997. From 1997 to 2013 his work there on this flora continued unabated, together with regular visits to the University's Botanic Garden throughout the flowering and fruiting seasons. He was co-author of Flora of Cambridgeshire (1964) and Flora of the Maltese Islands (1977), and was involved in the whole Flora Europaea project, also published in five volumes (1964-80) by Cambridge University Press.
Gina Murrell joined the Herbarium in the University of Cambridge's Plant Science Department in 1966, where she held the post of Assistant Curator from 2002 until her retirement in 2011. She worked with Peter Sell over a period of more than 40 years, and together they collected a quarter of the British Herbarium's 200 000 specimens.
"[...] In summary, this volume, like the previous ones is extremely comprehensive, though less so, even cursory when dealing with Ireland, especially in omitting key and standard references. For the non-specialist of critical and apomictic groups, its main usefulness lies in its inclusion of all species likely to be encountered in wild, ruderal and urban habitats and if you have often wondered which Cotoneaster is which then this volume can authoritatively guide you. If you are a devotee of critical and apomictic groups this is a ‘splitters delight’ and this book is for you. However, the steep price may put you off"
