Rare and Threatened Pteridophytes of Asia 2. Endangered Species of India - the Higher IUCN Categories

摘要

A revised list of 337 pteridophytes from political India is presented according to the six higher IUCN categories, and following on from the wider list of Chandra et al. (2008). This is nearly one third of the total c. 1100 species of indigenous Pteridophytes present in India. Endemics in the list are noted and carefully revised distributions are given for each species along with their estimated IUCN category. A slightly modified update of the classification by Fraser-Jenkins (2010a) is used. Phanerophlebiopsis balansae (Christ) Fraser-Jenk. et Baishya and Azolla filiculoi-des Lam. subsp. cristata (Kaulf.) Fraser-Jenk., are new combinations.
