Schizachyrium

Schizachyrium is a widespread genus of plants in the grass family. The name is derived from the Ancient Greek words σχίζειν, meaning "to split," and ἄχυρον , meaning "chaff." It refers to either the glume or the toothed lemmas.

In the United States, members of the genus are commonly known as bluestems.
