Status:

  • COSEWIC – Endangered.

Description:

  • Can be challenging to identify, this annual plant grows 30 to 50 cm tall. It is branched at the base and grows in tufts or dense clumps.
  • Stems are wiry and often rough; the leaves are 5 to 15 cm long and less than 1 mm wide. The “awns” referred to in its name are bristle-like structures attached to the bract (specialized leaf) that encloses the flower of the grass.
  • Inconspicuous flowers appear in August and continue into October.
  • Seeds are dispersed by wind and animals.

Habitat:

  • Sand barrens

Threats:

  • Impacted by cottage/recreation development, extraction of sand, and by all-terrain vehicles.
