Morphological and molecular identification of an endemic species from Tamil Nadu, India: Wrightia Indica Ngan (Apocynaceae)

Wrightia indica Ngan is an endemic Apocynaceae species collected from Sitheri hills of Dharmapuri district in the Southern Eastern Ghats of Tamil Nadu. Morphological and molecular identification of species was observed by analyzing the chloroplast DNA regions using ITS marker and generated sequences. The present study confirms the molecular sequence of Wrightia indica for the first time and voucher specimen deposited in NCBI. They allow us to infer the phylogenetic relationships among other taxa within the same genus and those of other genera detailed description, ecological notes, and photographs of the species are provided for a better understanding of this little known endemic taxa.
