Beyrich threeawn wiregrass (Aristida beyrichiana), more commonly known simply as wiregrass, is a perennial grass found throughout the southeastern United States. "Threeawn" refers to the species' three-pronged seedheads, called "awns." Prior to widespread human settlement, it formed a major portion of the understory in the longleaf pine ecosystem that once covered much of Alabama's southern half. It's prevalence in southeastern Alabama earned the region the name Wiregrass.
