Abstract
The paper throws light on the reasons for endemism of Calophyllum austroindicum – an economically important species occurring in the periphery of rivers and interior of forests in Tirunelveli Hills, Tamil Nadu. Present study has revealed that, possibly the endemism is caused by the fact that the population and reproduction biology is influenced by natural calamities, biotic and abiotic factors. The reduction in the germinability of the seeds is due to its recalcitrant nature. This species is also critically endangered. Both in situ and ex situ methods of conservation are proposed to overcome the possibility of extinction of this species.
