In dry soil, Missouri to Louisiana and Texas. Sporobolus attenuatus Nash has been reported as introduced along railroads in Jackson Co., Mo. It is related to the above and may be distinguished by its smaller spikelets about i}4" long. 6. Sporobolus asper (Michx.) Kunth. Long-leaved Rush-grass. Fig. 469. Agrostis aspera Michx. Fl. Bor.
