This is a very common tall reed familiar to the local peoples for its beautiful inflorescence in the autumn and economic importance; it grows abundantly on the plains and is cultivated as a windbeak between the fields, used as hedges, and for ornamental purposes. Cattle feed on this grass in time of need, and it is a good fodder grass.
