"This book presents an account of important aspects of living (Extant) and non-living (Fossil or extinct) gymnosperms. The special attention has been given on family wise comprehensive information of the group based on the representative genus available today. In this book all the recent aspects of naked seed plants have enumerated and nicely discussed, to make this book highly useful to undergraduate and graduate readers." (jacket)
