The early taxonomical studies of Nepalese plants were carried out by the Europeans mainly by the British botanists. As a result of which the first book on flora of Nepal ‘Prodromus Florae Nepalensis’ was prepared in 1852 by David Don. Although a few but notably important due to pioneer work of its kind on Nepalese flowering plants, taxonomical works on Nepalese plants were published from 1802 to 1947. Since 1949 many British, Japanese and Indian expeditions carried out plant explorations in Nepal and published many important findings. Many important works on Nepalese flowering plants were published between 1949 and 1982, especially three volumes of ‘An Enumeration of flowering plants of Nepal’ in 1978-1982 by Hara et al. Even after this publication many plant collecting expeditions in Nepal were carried out especially by the Japanese botanists. Researches carried out in the Central Department of Botany (Tribhuvan University, Nepal), University of Tokyo (Japan) and University of Edinburgh (U.K.) for M. Sc and Ph. D degrees are noteworthy. Studies on the flowering plants are still continuing and newly discovered species and new records for flora of Nepal are being added.
