This book entitled Plant Resources of Tiruvannamalai District, Tamil Nadu, India is a result of extensive and intensive field research in the Javvadhu hills of eastern ghats and its adjoinings within Tiruvannamalai district. The district not only harbours a diversified vegetation but also known for its medicinal plants wealth.

This book deals with a total of 1365 taxa of angiosperms collected from the district including 1278 species, 18 subspecies and 69 varieties coming under 713 genera, spread over to 158 families. Of these 1365 taxa, 1111 are occurring naturally and the remaining 254 taxa are cultivated or planted in the district.

The families are arranged as per Bentham and Hooker's system of classification with few modifications according to recent workers such as Hutchinson and Cronquist. Under each family the genera, and the species under each genus are arranged alphabetically. This book is profusely illustrated with more than 300 colour photographs.

All the naturally occurring taxa are described with nomenclature, local names, brief description, phenology, occurrence and global distribution. Notes on nomenclature, field observations, population status, threat status, distribution and trade and the local uses of plants are provided wherever required / available.

This book includes rediscovery of a species and several new distributional records including 1 species for India, 2 for peninsular India and 8 taxa for Tamil Nadu.

The book incorporates details of vegetational pattern, topography, geology, climatology, flora of forest and non-forest areas and fauna of the district.

The ethbobotany chapter illustrates the history of origin and distribution of Malayali tribes, tribes were documented for over 250 species, their life style and traditional knowledge on plants. A detailed analysis of the flora of the district is carried out and endemic plants, red listed species, phytogeographic affinities, phylogenetic importance, infra-specific variations are included. The book also exhibits various kind of threats faced by the plants and also suggests areas and species to be focused for immediate conservation action.

The book perhaps first of its kind published on plants of northern Tamil Nadu and is sure to contribute to the preparation of flora of the state. This work is also expected to be useful to botanists, ecologists, conservationists, managers of forests, horticulturists, plant breeders, plant introducers, teachers and students, producers and users of medicines, healers, pilgrims, town planners and to any plant lovers.
