Inflorescence units 3-50+ per culm; peduncles 2-13.2 cm, with 1 rame; rames 2-4 cm, usually long-exserted at maturity; internodes densely pubescent, hairs to 8 mm. Sessile spikelets 4-6 mm; lower glumes scabrous in the distal 1/2; awns 11-20 mm. Pedicellate spikelets reduced to an awned or unawned glume, sterile. 2n = 40.

Discussion
Andropogon gracilis grows on oolite in openings and rocky margins of pine woodlands of southern Florida and the West Indies. Although not uncommon, it is frequently overlooked. It has sometimes been placed in Schizachyrium because of its solitary rames.
Selected References
None.
