From the foreword: This is a revision and update of Catalogue of Nepalese Vascular Plants published in 1976 by the then Department of Medicinal Plants (now Department of Plants Resources). The present volume includes the list of plants preserved in Nepal’s National Herbarium (coded as KATH), an undertaking of the Department of Plant Resources. The major work of the National Herbarium and Plant Laboratories is to collect, identify, preserve and publish information on Nepal’s plant wealth such as Flora of Nepal.

The Catalogue of Nepalese Flowering Plants is prepared on the basis of the plant materials collected so far from the country by various plant collectors – national and foreign botanists since the Department started botanizing various parts of the country in 1960, and also joint scientic expeditions arranged with foreign institutions on various occasions. This has not only enriched the specimens in the herbarium, but it also presents a glimpse of the present condition of vegetation and floristic composition of the country. Further collections of plant specimens will be continued so as to make this catalogue complete and more comprehensive in the future.

This is the first supplement to the Catalogue of Nepalese Flowering Plants which was published in three parts by the Department of Plant Resources in 2010, 2011 and 2012. The Catalogues were prepared on the basis of the plant materials collected from Nepal by various plant collectors – national and foreign botanists and preserved in the National Herbarium of Nepal. Like the previous publications this book is also the results of work that the National Herbarium and Plant Laboratories of that Department are undertaking to fulfill one of its objectives, the preparation and publication of a Flora of Nepal. After the publications of the Catalogues in 2012 many new specimens have been added to the National Herbarium of Nepal and also many species have been named for the old unidentified specimens. As a result many species, which were not included in the Catalogues of Nepalese Flowing Plants Parts 1-3, were added to the National Herbarium. This necessitated bringing out the first Supplement of the Catalogues.

The book includes a list of 560 taxa belonging to 327 genera and 95 families including 20 new taxa for Nepal. This book, like the previous catalogues, will form a sound basis for further works and investigations on the flora, phytogeography and other aspects of vegetation studies of the country.
