Ecology & Life History

General Description: Tufted Club-rush is a perennial, grass-like plant with tufted, stems that are 1-4 dm tall and arising from short rhizomes. The leaves are clustered near the base and are reduced to scales or short blades. Several flowers are spirally arranged in a single, short, spike-like, terminal cluster, or spikelet, that is 4-6 mm long and subtended by a long-tipped scale. Each flower consists of a single scale subtending 3 stamens and an ovary with 6 white bristles that are as long as the scales and arising from the base. The 3-sided achene is ca. 1.5 mm long.
Diagnostic Characteristics: SCIRPUS CESPITOSUS could easily be mistaken for a species of ELEOCHARIS; however, the former has spikelets subtended by a short-awned scale, while the latter do not. ELEOCHARIS CESPITOSUS forms large, distinctive tussocks.
