Description

"Erect rhizomatous perennials. Spikelets compressed, glumes similar, shorter than lowest lemma. Lemmas 3-nerved, nerves ciliate, reduced upward, chartaceous; paleas equaling lemmas. Articulation below florets."[2]

"Perennial from elongate, scaly rhizomes, 2.5-5 mm thick; culms 8-12 dm tall, nodes and internodes glabrous. Leaves cauline, to 3.5 dm log, 2-7 mm wide; upper blades glabrous on both surfaces, lower blades sparsely pilose on both surfaces basally, margins smooth scaberulous; upper sheaths glabrous, lower, pilose; ligules ciliolate, 0.5 mm long.

Glumes 1-nerved, chartaceous, glabrous, retuse, cuspidate; 1st glume 3.5-4.5 mm long, 2nd glume 4-5 mm long; lemmas retuse, cuspidate, longest 4-5 mm long. Grain yellowish, ellipsoid, 2-2.5 mm long."[2]

Distribution

Tridens carolinianus is endemic to the east Gulf Coastal Plain, disjunct to North and South Carolina.[3]
