Index to scientific names. List of specimens examined (Appendix). Orchids are known for their beautiful flowers. They are also the most advanced family in the flowering plants. The botanical speciality and horticultural importance of orchids are narrated in the introduction of the book. The preface gives a picture of the earlier botanical account of Orissa. A brief account of the geography of the state the distribution of orchid account of the orchidrich habitats of the state have been provided. Important aspects like the lifeform growth habits and morphology of the Orissa orchids have been dealt in detail. The flowering period and periodicity as observed in the field during seasonal visits has been recorded. The present status of orchids in Orissa and measures for conservation has been suggested. In the systematics the taxonomy and classification of the Orissa orchids with brief keys to the subfamilies and exhaustive keys to the genera based on both floral and field characters are provided. The floristic analysis of the species has been dealt thereafter. The enumeration of the species provides detailed morphological description of each of the 130 species followed by their flowering and fruiting period taxonomical notes field notes dealing with flowering occurrence of the species in Orissa and their distribution within and outside India. Analytical drawings of the habit and the floral organs for each species drawn by the author from live specimens have also been provided for every species. The analytical drawings the colour photographs for a large number of species and the taxonomical notes will be helpful for identification of this rather difficult group of plants. 774 pp.<

Index to lichen taxa. The present book is the outcome of an extensive collection and critical investigation of more than 5 000 parmelioid specimens preserved in different herbaria of India representing all the phytogeographic regions of the country. A detailed study of this group shows greatest diversity of commonly growing lichens in India. Till date there has not been any comprehensive account on the parmelioid lichens in India is so far available. Keeping this in view the authors have tried to fulfil this lacunae by bringing out the book Parmelioid lichens in India. The present work includes systematic account of 192 species belonging to 22 genera with coloured photographs scanned pictures of TLC plates for secondary metabolites of each species current nomenclature key to the genera and species. For each species basionym synonyms information on type collection detail description chemistry remarks variation habitat and altitudinal distribution within and outside India along with maps are provided. Glossary of botanical names and terms used in the text are also provided. The important morphological characters to delimit genera and species along with scientific illustrations and scanning electron microscopic pictures are given in the general account. The conservation status of parmelioid lichens is also discussed. Extinct endangered vulnerable and endemic taxa are also listed. Eight localities are proposed as Lichen sanctuaries for the country owing to their luxuriant parmelioid flora. It is hoped that the present work covering various aspects of the parmelioid lichens will be of immense interest to students scientists teachers and other interested to peruse research particularly on the parmelioid lichens in India and world in general. 488 pp.<
