4. Endemism
The study area comes under the Western Ghat system of mountains and is rich in pteridopytic
flora due to remarkable variation in ecoclimatic conditions, soil types and altitudes. About 8
endemic species of India found naturally grown on the study area. The endemic species
reported during the period are Selaginella ganguliana, Selaginella inequalifolia, Selaginella
tenera, Chirstella parasitica, Bolbitis semicordata, Bolbitis prolifera, Pteris otaria, Pteris
quadriaurita. (Table 3; Plate 1)
5. Distribution of species in different habitat of study area
Pteridopytes are widely distributed due to the availability of favourable climatic conditions.
However they need proper microclimatic conditions for their survival. Some terrestrial
pteridophtic genera are Lycopodiella, Selaginella, Angiopteris, Dicranopteris, Cyathea,
