ABSTRACT

The paper describes comparative morphology of and Harappan carbo• nized grains identified as Efeusine coracana and of modern Ragi. The morphological details not described earlier are found to be similar in both, thus supporting the identi• fication of carbonized grains to Efeusine coracana

Key-words - Ragi, Carbonized grains, Protohistoric (India).
