    Ischaemum rugosum is a very variable species in which the pedicelled spikelet may be large and on a short pedicel (var. rugosum) or reduced and on a long pedicel (var. segetum). Although common over much of India, it is found only occasionally in Pakistan. It is eaten by horses and cattle when young.
