Its economic importance is primarily negative, as both I. cylindrica and I. brasiliensis are weedy (Gabel 1989), but new shoots of both species are used for hay or grazing. Imperata is thought to be closely related to Miscanthus. One species is native to the Flora region, and two have been introduced.</p> |tables= |references={{Treatment/Reference |id=gabel1989a |text=Gabel, M.L. 1989.
