Bulrush or bullrush is the common name of a variety of wetland plants, typically in the sedge family (Cyperaceae).
The name is particularly applied to the sedge family genera Bolboschoenus, Cyperus, Scirpus, and Schoenoplectus. Outside of this family, the name is used for Typha, a genus in the Typhaceae family, also known as reedmace or cattail.
A famous story involving bulrushes is that of the Ark of bulrushes, in which the infant Moses was found. Within the context of the story, this is probably paper reed (Cyperus papyrus)
