Synopsis In this publication, a brief general introduction on the floristics of the different mangroves in India; identification keys to the families, genera and species; species-wise data-sheets with recent botanical names (in bold print; synonyms in italics), its family, local names, short botanical descriptions, notes on ecology, distribution and economic uses, etc. have been provided.  Relevant commonly consulted floras have been given under references.  At the end a list of common mangrove-associate species (which do not exhibit true mangrove adaptative characteristics), a glossary of botanical terms and some important references suggested for reading, have been appended.  An index is dispensed with and an alphabetical arrangement of the families, genera, species and varieties has been followed for easy reference, irrespective of their positions in the taxonomic keys.  Colour and black and white photographs and habit sketches for many species are included for familiarizing the users of this manual on the beauty and richness of mangroves both collectively and individually.
