Any of the annual or perennial grasslike plants constituting the genus Scirpus, especially S. lacustris, in the sedge family, that bear solitary or much-clustered spikelets. Bulrushes grow in wet locations, including ponds, marshes, and lakes. Their stems are often used to weave strong mats, baskets, and chair seats. Bulrushes may act as a filter, absorbing poisonous metals and toxic microorganisms, thus helping to reduce water pollution. In Britain, the term bulrush refers to either of two cattails (Typha latifolia and T. angustifolia).
