Epiphyllous liverworts, Diversity, Distribution, IndiaAbstract
Taxonomy of the epiphyllous liverworts in India has been reviewed and their diversity and distribution has been discussed. A total of 160 species, one subspecies and two varieties of epiphyllous liverworts belonging to 23 genera in eight families have been recognized in Indian bryoflora, distributed only in eastern Himalaya and the north-east, Western Ghats, and the Andaman & Nicobar Islands. Eastern Himalaya, including the north-east, with 133 taxa shows the maximum diversity of epiphylls, whereas Sikkim with 80 taxa is the richest amongst the States. Lejeuneaceae with 131 species belonging to 16 genera is the most prolific family of epiphyllous liverworts accounting for over 80 per cent of their total diversity in India, while Cololejeunea with 54 species is the most dominant genus. Twenty species are endemic to India, of which 11 are restricted to eastern Himalaya, three to Western Ghats, and one to Andaman & Nicobar, while five species are common between eastern Himalaya and the Western Ghats.
