Discussion
Sorghastrum elliottii usually grows in dry, open woods on sandy terraces of the lowlands in the southeastern United States, often over a clay subsoil. Plants with straight panicles and sessile spikelets that are 1.3-1.8 mm wide are sometimes called S. apalachicolense D.W. Hall, but the variation appears to be continuous and such plants are included here as S. elliottii.
