Plants rhizomatous, densely cespitose. Culms 20-30 cm. Sheaths reddish brown, glabrous or pubescent, shredding into fibers, cauline leaf sheaths loosely or tightly enclosing the culms; blades 0.7-1.5 mm in diameter, conduplicate; abaxial sclerenchyma in narrow strands; adaxial sclerenchyma sometimes present. Inflorescences mostly congested, lanceolate, often partially included in the uppermost leaf sheaths at maturity; branches scabrous. Spikelets to about 12 mm, with 4-8 florets. Lower glumes 2.5-3.2 mm; upper glumes 3.5-4.6(5) mm; lemmas 4.5-6 mm, glabrous or pilose, acuminate in side view, apices awned, awns 0.5-2 mm; anthers 2.5-3 mm long. 2n = 42 [for Festuca rubra var. littoralis Vasey ex Beal].
