Hippomanioideae. v. Oldfieldioideae. vi. Phyllanthoideae. III. Bibliography. Index. Euphorbiaceae is a complex hetero geneous family consisting of about 322 genera and 8900 species in the world. 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 first comprehensive book on the family Eriocaulaceae, popularly known as Pipeworts complete with descriptions and illustrations was the result of efforts of the authors for several years. The book was originally published in 1994 as a taxonomical monograph of 65 Indian species of the genus Eriocaulon Linn. with eight new species and five new names attributing specific status to the infraspecific taxa of earlier workers. The present edition includes 16 new taxa described by various workers from time to time ever since the publication of the book. One of those new species viz. E. Konkanense Punekar et al., has been reduced to synonym. In this revised edition, the newly added species have been incorporated in the twelve sections treated in the original book by circumscribing the section characters wherever necessary. However, the general pattern of the original book is maintained and the character - parameters used in preparing the identification key have been retained. The geographical distribution of each taxon within the county is discussed and depicted in the maps. All species are illustrated and a unique method is adopted for showing the enlargement scale. This revised edition will be helpful to the researchers and students involved in the floristic studies, especially of the wetlands which receive greater scientific and conservative importance in these days. …

"The genus Euphorbia, belonging to the family Euphorbiaceae, is unique among flowering plants due to the peculiar highly evolved inflorescence called cyathium, which is found only in this genus and a few of its allied genera. For India, the only treatise available now for the genus covering the entire country was published about 120 years ago by J.D. Hooker for Flora of British India (Vol. 5, 1887). Since then except for some regional works, none has attempted a taxonomic account of the genus for the entire country. After many years of survey work and research work, the authors have now brought out a comprehensive up-to-date taxonomic revision of the interesting genus for India. The genus Euphorbia has 80 species indigenous to India and 4 exotic, introduced and naturalized ones. The genus is rich in endemism with 30 species and 7 varieties endemic to India. This work provides a detailed introduction, reviewing earlier works on all aspects of morphology, anatomy, cytology, embryology, palynology, economic botany, phylogeny, etc. The taxonomic part provides detailed descriptions for the genus, subgeneric taxa, species and infraspecific taxa. Simple dichotomous keys are presented for easy identification of subgenera, sections, species and infraspecific taxa. Line drawings with detailed morphological features have been provided for 77 species, many of them published for the first time. The work also includes 40 photographs, including those of some type specimens. A comprehensive bibliography includes citations of important literature relevant to India. Alphabetic indexes to botanical and vernacular names are provided. This work will be useful for students, teachers and researchers of Botany and allied branches and will also prove useful to all workers in applied aspects for correctly identifying their specimens.". …
