Third List of Species and Genera of Indian Phanerogams not Included in J. D. Hooker's Flora of British India (Excluding Bangladesh, Burma, Ceylon, Malayan Peninsula and Pakistan)

Calder et al. (1926) presented the first list of Phancrogams not included in J.D. Hooker's Flora of British India and it covered a span of twenty six years between 1898-1924. Razi (1959) enumerated the second list of Indian Phanerogams supplementing Calder's list for the period from 1924 to 1950 and this again covered a period of twenty six years. The third list now presented by the authors spanned a period of twenty five years (1950-1975) and the plants enumerated is geographically delimited to India, Bhutan and Nepal. In the present list the authors have listed about 1000 taxa of Phanerogams added to the Indian flora supplementing the lists of Calder (1926) and Razi (1959). The countries Bhutan and Nepal are part of Himalayan region and for any study of Himalayan flora of India, it is necessary to understand the floristic elements of Nepal and Bhutan since many Himalayan elements occur in the contiguous territories of India, Bhutan and Nepal.
