Synopsis The Flora of Mizoram is proposed to be published in three volumes. The present volume, dealing with general chapters, like introduction, physiography, climate, geology and soil, forests and forest types, botanical studies, forestry, economic plants, floristic diversity, references, key to the families etc. includes taxonomic account of 884 taxa belonging to 403 genera and 90 families from Ranunculaceae to Asteraceae. Of these 172 species and one variety have been recorded for the first time from the state. As Southern and South-Western part of the state still remain to be thoroughly explored, many more species are expected to be added in future. It is hoped that the flora will be useful to the forest managers, botanists, researchers and all those concerned with the study, conservation and sustainable utilisation of the plant resources in the state of Mizoram.
