A Synopsis of Hypericaceae in Indian Sub-continent : its Distribution and Endemism

A preliminary checklist of Hypericaceae in Indian sub-continent has been prepared on the basis of primary observations of different taxa belonging to this family in wild habitats and on secondary observations based on examining herbarium specimens and taxonomic literature. In the Indian sub-continent (comprising Bangladesh, Bhutan, Myanmar, Nepal, Pakistan, Sri Lanka and India), the family Hypericaceae is poorly represented with 10.2% of global distribution. The present paper deals with distribution, phytoendemism, possible fossil ancestry, potential, survival threat etc. on existing taxa etc. of Hypericaceae in Indian sub-continent. For better understanding of the species dynamics of Hypericaceae in Indian sub-continent, the present status of phytoendemism has been compared with the data of previous investigations done in the Nineteenth century.
