Many dark purplish-brown spikelets, without awns but with long silky hairs on stalks. Flat, smooth leaves, greyish beneath. Sheaths split, line of short hairs instead of ligules. Stems 125-250cm.
Very frequent at lake edges and in ditches, marshes and canals. Used in thatching and planted as reed-beds for water-purification.
