Species: Cyperus schweinitzii
Encyclopedia of Puget Sound
Schweinitz' Flatsedge is a grass-like perennial with stems that are 10-40 cm high, arising from short, irregularly swollen rhizomes. The leaves are 1-4 mm wide and located mostly near the base of the plant. The inflorescence is subtended by 3-6 long, leaf-like bracts, some of which are wider than the leaves. The infloresence is made up of ascending clusters of flattened spikelets that are 5-25 mm long and borne on stalks that are very short to long. The flowers are crowded opposite each other and consist only of a small, pointed scale, which is ca. 3-4 mm long and subtends 3 stamens and an ovary. The seed is triangular in cross-section.
