New Flora of the British Isles: 2nd edn.
CUP. 1997
Since its publication in 1991, New Flora of the British Isles has become
the standard work on British plant identification.
It is designed to be user-friendly throughout and to serve as a practical database for
taxonomists, ecologists, conservationists, plant geographers, teachers and students,
as well as for amateur botanists and plant hunters.
The descriptions have been drawn up using living plant material as well as the literature,
and the keys have all been written anew, with the aims of simplicity, unambiguity and accuracy borne in mind.
The plants included cover all natives, all naturalized plants, all crop plants and all recurrent casuals.
The format of the book ensures ease of use both in the laboratory or home and in the field.
Technical terms are used wherever necessary but are kept to an essential minimum.
Over 160 pages of specially prepared illustrations are provided,
including line diagrams or photographs of diagnostic parts of critical groups,
and plant portraits of less familiar, alien species for which illustrations are not readily available.
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.
