Species: Schoenoplectus subterminalis
Encyclopedia of Puget Sound
Water Bulrush is a rhizomatous perennial with slender, weak stems that are 20-80 cm long and which float on the water's surface rather than emerging from it. Leaves are long and flaccid and arise mainly from near the base of the plant. The inflorescence consists of a solitary spike subtended by a green, leaf-like bract that is 1-6 cm long and held nearly erect, appearing to be a continuation of the stem. The light brown spike is composed of numerous, membranous scales, each subtending a flower consisting of 3 stamens and an ovary with 6 slender bristles arising from the base. The ovary matures into a three-sided achene that is 2-4 mm long.
