Aristida Overview

Aristida is a large genus with over 300 grasses in the Poaceae family, distinguished by possessing three bristles on each spikelet of their small flowers and named three-awns, wiregrasses or needlegrasses. They are distributed worldwide, mostly in arid and warm climates in grass and scrubland. Observation of grasses such as these can provide land quality information, as increases in their abundance can indicate livestock overgrazing as they tend to avoid consuming these grasses. Aristada junciformis is a popular indigenous ornamental grass species within this genus.
