Garnotia stricta

HABIT Perennial; short-lived. Culms erect, or geniculately ascending, or decumbent; 10–60 cm long; wiry; without nodal roots, or rooting from lower nodes. Culm-nodes glabrous, or bearded. Ligule a ciliolate membrane; 0.3–0.5 mm long. Leaf-blades 3–40 cm long; 2–15 mm wide.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear; 5–40 cm long.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 2.5–5 mm long; falling entire. Spikelet callus pubescent; base obtuse.

GLUMES Glumes similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 2.5–5 mm long; 1 length of spikelet; membranous; 1-keeled; 3 -veined. Lower glume lateral veins ribbed. Lower glume apex acute; muticous, or awned; 1 -awned. Lower glume awn 0–4 mm long. Upper glume lanceolate; 2.2–4.5 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume lateral veins ribbed. Upper glume apex acute, or acuminate; muticous, or awned; 1 -awned. Upper glume awn 0–4 mm long.

FLORETS Fertile lemma oblong; 2–4.5 mm long; cartilaginous; without keel; 3 -veined. Lemma margins involute; interlocking with palea keels. Lemma apex dentate; 2 -fid; muticous, or awned; 1 -awned. Principal lemma awn from a sinus; straight, or geniculate; 1–2 mm long overall (when straight), or 6–14 mm long overall; without a column (when straight), or with twisted column. Palea with auriculate flaps; 1 length of lemma; cartilaginous; 2 -veined. Palea keels winged (below); narrowly winged.
