Anotations

Scope note:

Genus containing 120 to 300 species (depending upon the classification) of annual or perennial aquatic, grasslike species growing in ponds, marshes, and lakes. They bear solitary or small clustered spikes. 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. The taxonomy of the genus is complex and currently under review, which will likely result in some species being moved to other genera. In English translations of the Bible, the term "bulrush" is mistakenly used to refer to the papyrus plant, Cyperus papyrus. In Britain, the term "bulrush" is sometimes used to refer to species of genus Typha.
