Clinton's bulrush

Clinton's Bulrush, Schoenoplectus clintoni, is a perennial wetland sedge in the family Cyperaceae with a restricted distribution in parts of the northeastern United States, named in honor of DeWitt Clinton, an early American naturalist and statesman. Like other bulrushes in the genus Schoenoplectus, it grows in shallow water and wet soils at the margins of lakes, ponds, marshes, and slow-moving streams. The stems are triangular or round in cross-section, bearing clusters of small, brownish spikelets characteristic of the genus. Bulrushes provide critical ecosystem services in wetland habitats, stabilizing shorelines, filtering water, providing nesting cover for marsh birds, and furnishing food through their seeds and starchy rhizomes for waterfowl and mammals. Clinton's Bulrush is considered rare within its limited northeastern range and faces threats from wetland drainage, development, and invasive species including common reed (Phragmites australis) that displace native emergent vegetation. Wetland loss across the northeastern United States has significantly reduced the area of suitable habitat for specialist wetland plants. The species is protected or of concern in several states where it occurs.
