Description

Andropogon gyrans is a perennial grass. Andropogon gyrans had an average height of 24 inches. The flowers typically bloom from August to October. The culms of Andropogon gyrans often exhibit glaucous internodes, with mostly erect and straight branches. The sheaths are smooth, and its ligules measure 0.3 to 1.5 millimetres, occasionally adorned with cilia up to 0.7 millimetres. Its blades range from 6 to 48 centimetres in length and 0.8 to 5 millimetres in width, presenting variations in pubescence from being glabrous to densely covered in spreading hairs. Andropogon gyrans typically bears 2 to 31 units per culm. The peduncles each bear 2 to 5 rames. The rames have a pubescence density increasing distally within each internode. The keels of lower glumes are scabrous only beyond midlength, while the awns measure between 8 and 24 millimetres. Anthers are singular and can appear yellow or purple. Pedicellate spikelets are either vestigial or absent.
