Schoenoplectus

Schoenoplectus (club-rush [Old World species], bulrush or tule [New World species]) is a genus of plants in the sedges with a cosmopolitan distribution.[1][2][3] Note that the name bulrush is also applied to species in the unrelated genus Typha as well as to other sedges. The genus Schoenoplectus was formerly considered part of Scirpus, but recent phylogenetic data shows that they are not closely related.
