Plants perennial; densely cespitose, without rhizomes. Culms 1-1.5 m,erect. Sheaths persistent, smooth to scabridulous, becoming fibrous at the base at maturity; ligules 0.8-2.9 mm; blades to 46 cm long, 5.1 mm wide, glabrous abaxially, scabrous adaxially, sometimes also pilose just above the ligules. Panicles with 1 branch; branches 5-15 cm, curved, axes extending slightly beyond the spikelets, distal spikelets reduced. Spikelets 8.5-11 mm. Lower glumes 1-2.1 mm; upper glumes 4.8-6.1 mm, bidentate, with a row of conspicuous glands on either side of the midveins, awns 3.5-4 mm, strongly divergent, often almost perpendicular to it at maturity; lemmas of bisexual florets 4-5 mm, pilose on the lateral veins, awned subapically, awns 3-4 mm, straight or divergent; distal lemmas sterile, unawned. 2n = unknown.

Ctenium aromaticum is a common species that grows in wet to moist pine flatwoods, savannahs, prairies, pitcher plant bogs, and ecotones between pine uplands and wet streamheads of the southeastern coastal plain. It furnishes fair forage, and the roots are spicy when freshly dug.

Culms densely tufted, 8-15 dm, hairy at the top; lf-blades smooth, 1-3 mm wide; spike usually curved, 5-12 dm; first glume (on the inner side of the spike!) 1.5-2.5 mm; second glume 4-7 mm, pubescent, the veins glandular below the middle, the awn 4-6 mm; lemmas conspicuously ciliate, especially at the middle, 4-6 mm, the fertile one and the two lower sterile ones with awns 2-6 mm, the upper sterile lemma single and awnless. Wet pine-barrens; se. Va. to Fla. and La. (Campulosus a.)
