Garnotia linearis

HABIT Perennial. Culms erect, or geniculately ascending, or decumbent; 45–90 cm long; without nodal roots, or rooting from lower nodes. Culm-nodes pubescent. Leaf-sheaths pilose. Leaf-sheath oral hairs bearded. Ligule a ciliolate membrane; 0.3–0.8 mm long. Leaf-blades 13–20 cm long; 3–6 mm wide. Leaf-blade surface glabrous.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear; 15–35 cm long. Primary panicle branches distant; 1 -nate; simple; 2–5 cm long; 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; 4–5 mm long; falling entire. Spikelet callus glabrous, or pubescent; base obtuse.

GLUMES Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 4–5 mm long; 1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume apex acuminate; muticous, or awned; 1 -awned. Lower glume awn 0–7 mm long. Upper glume lanceolate; 4–5 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acuminate; muticous, or awned; 1 -awned. Upper glume awn 0–1 mm long.

FLORETS Fertile lemma oblong; 4–5 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; 8–14 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.

NOTES Arundinelleae. Gould.
