Distribution: Distribution: Pakistan (Punjab, N.W.F.P. & Gilgit); tropical Asia and America; introduced and naturalised in Tanzania.
Comment/Acknowledgements: Digitaria violascens is closely allied to Digitaria longiflora. The two species intergrade to some extent, and there are no infallible characters for separating them. Typically Digitaria violascens is a more erect plant with 3 or more slender racemes, scabrid pedicels, a smaller upper glume (commonly 3-nerved and noticeably shorter than the spikelet) and a dark-coloured fruit.
