Шаблон:Short description Шаблон:Automatic taxobox

Astrebla is a small genus of xerophytic (adapted to survive in an environment with little liquid water) grasses found only in Australia.[1] They are the dominant grass across much of the continent.[2] They are commonly known as Mitchell grass after Scottish explorer Thomas Mitchell (1792-1855), who first collected a specimen near Bourke in New South Wales.

Mitchell grasses grow on clay soils, mainly between an upper limit of Шаблон:Convert and a lower limit of Шаблон:Convert average annual rainfall, and at even lower rainfall in depressions where the water concentrates following rains, for example in Sturt's Stony Desert. Mitchell grasses are deep-rooted and become dormant during drought, allowing them to survive extended periods without rainfall.[3][4]

They are commonly found clumped together and reaching one metre high, providing habitat for organisms such as mammals.[5]
