Alopecurus

Alopecurus aequalisAlopecurus aequalis 2

Pictured above: Alopecurus aequalis

This genus is characterized by dense cylindrical spike-like inflorescences containing 1-flowered spikelets. At maturity the entire spikelet, including glumes, falls from the plant. Glumes are awnless, apically rounded, generally united in their basal portion, strongly keeled, and with cilia on the keel. Lemmas are about as long the glumes and have an awn attached on the back, which extends only slightly beyond the glumes.

There are 3 species in MN; 2 native.

  • Synonyms: None
  • Common names: short-awn foxtail
  • Origin and habitat: Native; moist habitats, especially along marshy shores
