Abstract

Twenty two species of genus Pyrrosia are described from India. In addition, two more species are doubtfully (P. ceylanica, P. angustata) recorded from South Indian mountains. Majority of the species are met with in the Himalayas from Garhwal to Bhutan. So far no species is recorded from Central as well as Western India. Pyrrosia acrostichoides and P. gardneri are restricted to Southern India. Quite a many of the species look alike but can be segregated on the basis of rhizome scales and hairs on the lamina as well as the spores. This is particularly true of the species belonging to P. stictica, P. mollis, P. mannii, P. nayariana and P. gardneri groups.
