Phenology
Identification
Taxonomic CommentsThe genus Aristida is most notable for the 3 hairlike awns which project from each floret. The central awn is almost always thicker than the other 2 awns. The awns may stand erect, especially during the early flowering period, but in most species eventually are bent parallel to the ground. In some species, only the central awn is bent, while the other 2 remain erect. In some species, all awns are the same length, while in other species the central awn is distinctly longer. The awns have tiny barbs which catch onto hair and fur, and florets will even hitch a ride up the inside of your pants!
