Brief Summary

Read full entry
Eleocharis acicularis occurs from the Arctic to cool-temperate North America, including higher elevations in the southwest USA; moreover, similar taxa in northern Europe presumably belong to E. acicularis, which was described from Europe. This plant is considered a nuisance to certain crops and is often treated with herbicides such as Tetrahydropyrimidinones.

This species has culms cylindric or three- to four-angled; leaf sheaths are mostly obscure and closely sheathing; and achenes about two times longer than wide.
