Avena strigosa

provided by wikipedia EN

Avena strigosa (also called lopsided oat, bristle oat or black oat; syn. Avena hispanica Ard.) is a species of grass native to Europe. It has edible seeds and is often cultivated as animal feed in southern Brazil. It is sometimes reported as a weed.

Description

Avena strigosa is a tufted grass growing to a height of 0.8–1.5 m. Its seeds are smaller than those of the common oat, Avena sativa.[1]

Uses

Avena strigosa used to be cultivated as human food in Scotland, but it is now cultivated as a forage for ruminants in South America. It is a nutritive grass with a good protein content.[1]
