Brown-top Bent - introduced (*Agrostis capillaris)

Home..... Menu..... Common name index..... Scientific name index..... Glossary ..... Other grasses ..... The grass plant

Alternative names: Common Bent.

Family. Poaceae (Grass family).

Native to Europe.


Each flower (spikelet) has a single lemma. The spikelets are small, 3mm long, excluding any awn. The lemma has a thinner texture than the glumes. The lemmas may have a slender awn rising from the back of the lemma, or be awnless. The awn, if present, is about as long as the glumes.

Unlike the similar Blown Grass, Lachnagrostis, in which the lemmas are also thin-textured, the flower clusters of Brown-top Bent do not separate from the plant when mature.

Brown-top Bent is widespread and common. It is used as a lawn grass, and is often abundant along roadsides and in paddocks.

It is also an environmental weed.

Agrostis: from the Greek word for field. capillaris: fine, hair-like.
