HABIT Perennial; mat forming. Culms decumbent, or prostrate; slender; 20–45 cm long. Culm-nodes glabrous. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs lacking. Ligule a ciliolate membrane; 0.3–0.5 mm long. Leaf-blades spreading, or reflexed; 2–6 cm long; 1.5–3 mm wide. Leaf-blade surface glabrous, or hirsute; sparsely hairy; hairy adaxially.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear; 3–8 cm long. Primary panicle branches appressed; 1–2 -nate; bearing spikelets almost to the base.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 3–4 mm long; falling entire. Spikelet callus glabrous; base obtuse.

GLUMES Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 3–4 mm long; 1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume apex acute to setaceously attenuate. Upper glume lanceolate; 3–4 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acute to setaceously attenuate.

FLORETS Fertile lemma oblong; 3–4 mm long; cartilaginous; without keel; 3 -veined. Lemma margins involute; interlocking with palea keels. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn straight, or flexuous; 4–9 mm long overall. Palea with auriculate flaps; 1 length of lemma; cartilaginous; 2 -veined. Palea keels winged (below); narrowly winged.

FLOWER Lodicules 2; cuneate; fleshy.

DISTRIBUTION Pacific: southwestern.
