Abstract

A preliminary checklist of Tamaricaceae in the Indian subcontinent 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. On the Indian subcontinent (comprising Bangladesh, Bhutan, Myanmar, Nepal, Pakistan, Sri Lanka and India), the family Tamaricaceae is poorly represented (20% of all species). The present paper deals with a brief review of distribution, endemism, possible fossil ancestry, economic potential and survival threat on existing taxa, etc. The present status of endemism of Tamaricaceae in Indian subcontinent (22.5% in 2002–2007) has been compared to the data of previous investigations (50% in 1939–1940) done in nineteenth century. The decreasing rate of endemism either indicates decreasing number of endemic taxa or increasing span of distribution of pan-endemic taxa belonging to this family. For better understanding of the functional aspects of species dynamics the rate of endemism in percent of a particular group of plants has been used as key index here.
