Book Description
Over the past 50 years, major changes have taken place in the distribution of aquatic plants in Europe. Many species have declined whilst other species have increased in abundance or spread, including several that were originally introduced from the New World. Despite the relative richness of the aquatic flora of Britain and Ireland, it is a neglected area of study. This book is not an identification manual but provides a summary of the distribution, habitat and reproductive biology of 200 taxa in 72 genera, with individual distribution maps, and also summarizes their distribution overseas. A joint project of I.T.E. (now C.E.H.), the Joint Nature Conservation Committee and the Environment Agency.

Book Description
Planned in five volumes, this new, critical Flora provides a definitive account of the native species, naturalized species, frequent garden escapes and casuals found in the British Isles. Full keys and descriptions should enable the botanist, researcher or informed amateur to name all plants occurring in the wild, plus some ornamental trees and shrubs. Detailed accounts of all the large apomictic genera are given and many infraspecific variants. Each species entry begins with the accepted Latin name, synonyms and the common English name. A detailed description follows, with separate descriptions being given for infraspecific taxa. Includes information on status, ecology and distribution. Clear black and white line drawings illustrate an extensive glossary and also illuminate the diagnostic features of a number of groups of plants.

Book Description
Aquatic ecosystem and aquatic plant diversity holds a key position in maintaining the floristic diversity of India - one of the 12 megabiodiversity centres of the world. It provides the material basis for the sustenance of thousands of floral and faunal aquatic life forms. This book ``Wetland Phytodiversity : A Complete Guide to Indian Helobieae'' deals with 75 plant species belonging to the aquatic families of angiosperms under the group Helobieae. Distribution of the taxa, their life forms, floral as well as pollination biology, phenology, chromosome numbers, etc. have been dealt with proper care towards better understanding of the affinities, intra - and interfamilial relationships of the taxa. Chapters on phytogeography, pollen morphology, fossil records etc. will be very much helpful for future workers in tracing origin and segregation of this important aquatic group of angiosperms. Apart from the text 20 maps/figures, 66 illustrations, 24 plates have been provided in the book.
