Astrebla lappacea

About

Astrebla lappacea, commonly known as curly Mitchell grass, is a herb of the family Poaceae from the order Poales. It grows to 0.9 metres (3 ft) tall. Named in honour of Thomas Mitchell, the Latin specific epithet of lappacea is derived from lappa meaning with burrs. The most common of the Astrebla species, it is a widespread Australian inland plant. It is often seen on floodplains and heavy self-mulching clay soils, and flowers in response to rain or flooding. This grass is palatable to livestock, even when dry.
