| Dulichium arundinaceum (L.) Britt. |
Dulichium is a monotypic genus of sedge containing the single species Dulichium arundinaceum, which is known by the common name threeway sedge. This is an aquatic or semi-aquatic plant of the lakes, streams, and ponds of North America. It has a wide distribution, covering much of the continent. It has a thick rhizome system and grows to heights approaching a meter. It is reminiscent of bamboo in appearance when new, growing bright green erect stalks in large, grassy stands. The leaves sheath the stems, and the inflorescence grows from the leaf axilla. The spikelets are generally lance-shaped and one to three centimeters long when ripe.
