Distribution of Andrographis species in Different Districts of Andhra Pradesh

Andrographis is a medicinally important genus of 26 species native to India, with greatest species diversity occurring in southern India. The present study provides the natural range of eleven species of Andrographis in Andhra Pradesh. Of these, nine species show narrow distributional range and are vulnerable to unsustainable harvesting and land use changes. As the first step towards the conservation and prioritization of the valuable taxa, this study presents data on diversity, spatial distribution and habitats of Andrographis species in the state of Andhra Pradesh.
