Researchers from Kerala have identified an edible tuber found in the Western Ghats region of Wayanad district as a new species of the genus Dioscorea.

The species, named Dioscorea balakrishnanii after V. Balakrishnan, environmentalist and current secretary of the Kerala State Biodiversity Board, holds potential as a tuber variety for food security and cultivation as a food crop with low glycemic index, the researchers said.
