Ecology & Life History

General Description: Beaked Spikerush is a grasslike perennial with stems that are 4-10 dm long, 1-2 mm wide, and clustered on a rootstock. All leaves occur on the lower stems and are reduced to sheathing scales, making the plants appear leafless. Longer stems arch over and root at the tips, forming new plants. The flowers are composed of ca. 6 bristles subtended by a blunt, lance-shaped, brownish scale that is 3-5 mm long and has a pale midrib; there are 3 stamens. 10-20 flowers are spirally arranged in a solitary conelike spike, 8-13 mm long, at the tip of the stem. The green to brown, egg-shaped, 3-sided seed or achene, is 2-3 mm long and tapers to a prominent beak.
Diagnostic Characteristics: The triangular beak is notched all around the base where it attaches to the body of the achene in E. PALUSTRIS. In E. TENUIS, the base of the beak is set in a dishlike depression at the top of the achene. The stems of E. ROSTELLATA rooting at the tips is diagnostic.
