In India this family is represented by 73 genera and 410 species. The family is essentially tropical and occurs in diverse habitats from arid regions to humid tropics. As a result the plants of this family have developed various life forms from herbs shrubs stunted succulents to tall canopy trees. Several important economic as well as medicinal plants such as rubber cassava castor tung oil phyllanthus emblica P. amarus etc. are found in this family. Jatropha curcas (Barbados nut physic nut) has recently become economically very important as the oil from the seeds of this plant can be uses as a non polluting substitute for automobile fuels. Large scale cultivation of this species is being undertaken in India. The one and only comprehensive taxonomic treatment of the family for India was that of J.D. Hooker (in flora of British India Vol. 5) published in 1987 88. Since then the family has been dealt with in several regional floras in India. A few genera have been taxonomically revised on All India basis or regional basis. The intensive botanical explorations conducted by Botanical Survey of India since 1956 added several new species new varieties and new records for India. Further there are several short papers published in recent years on nomenclature and taxonomy. Considerable work has been done in India on anatomy cytology embryology ethnobotany palynology and phytochemistry of selected genera during the last 50 years. However nobody has so far attempted a complete taxonomic revision of the family for India during the last 118 years. Under the ambitious flora of India project initiated in the year 1986 by Botanical Survey of India the present authors took up the family for taxonomic revision. After years of sustained work in association with a few research scholars it has been possible now to present a complete revision of the family. This is the first comprehensive taxonomic account of the family made to facilitate the research workers on this family in India and neighbouring countries. A detailed floristic revision of the family with full description of the species will be published soon in Volume 23 of Flora of India. However as a precursor we are now presenting in this book a synopsis of the family. The first part of this work includes an introduction containing history general morphology anatomy cytology embryology palynology phytochemistry pollination dispersal distribution and a chapter on the economically and medicinally useful species with their vernacular names and uses. This is followed by a taxonomic treatment of the family where the Indian taxa up to specific and infraspecific levels are provided with keys for easy identification. Descriptions are provided for the family subfamilies tribes and genera. For each taxon essential nomenclatural citations types and distribution within India and world are indicated. A detailed bibliography is included which not only indicates references cited in the text but also includes several other references having relevance to the study of Indian Euphorbiaceae. Colour photographs of selected species have been included. This book will help all future workers of the family in India and adjacent countries an easy tool for identification up to specific level and a guide to relevant literature on all aspects of the family. 500 pp.

The family Phyllanthaceae is a segregate of the heterogeneous mega-family Euphorbiaceae, based on phylogenetic considerations, placed in the order Malpighiales under Eudicotidae, a clade in flowering plants. The family is distinct in their pollen grains showing three colpi or grooves paralleling the polar axis and biovulatelocules of ovaries. They also show bitegmic ovules with non-vascularized inner integument and exarillate seeds. The family is cosmopolitan mainly distributed in humid tropics. The authors have revised the family as represented in India, Pakistan, Nepal, Bhutan, Bangladesh, Burma (Myanmar) and Sri Lanka forming a distinct phytogeographical conglomeration. This work includes 2 subfamilies, 6 tribes, 16 genera and 214 species. The biggest genus is Phyllanthus with 67 species, which includes the medicinally important Amla, the Indian gooseberry (Phyllanthusemblica). There are several economically and medicinally important species in the family. The work provides detailed descriptions of the family, subfamilies, tribes, genera and species. For easy identification bracketed keys to all levels of classification are provided. For each species, detailed nomenclature, typification, description, flowering and fruiting period, local names, habitat, distribution and specimens examined have been provided. Photographs of 93 species have been included for quick identification. A comprehensive bibliography includes citations of important literature relevant to the area.
