Garnotia tenella

HABIT Annual; caespitose. Culms geniculately ascending, or decumbent; 15–60(–90) cm long; without nodal roots, or rooting from lower nodes. Culm-nodes bearded. Leaf-sheaths outer margin glabrous, or hairy. Ligule an eciliate membrane, or a ciliolate membrane; 0.3–1.5 mm long. Leaf-blade base broadly rounded. Leaf-blades lanceolate; 3–15 cm long; 4–15 mm wide. Leaf-blade surface glabrous, or hispid; hairy adaxially, or on both sides.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear; 5–15 cm long. Primary panicle branches appressed; bearing spikelets almost to the base. Panicle branches scabrous.

Spikelets in pairs, or in threes. Fertile spikelets pedicelled. Pedicels linear; angular; scabrous.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 2–4 mm long; falling entire. Spikelet callus glabrous, or pubescent; base obtuse. Spikelet callus hairs 0–0.5 mm long.

GLUMES Glumes similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 2–4 mm long; 1.1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume surface scabrous; rough on veins. Lower glume apex acuminate; muticous, or awned; 1 -awned. Lower glume awn 0–3 mm long. Upper glume lanceolate; 2–4 mm long; 1.3–1.5 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume surface scabrous; rough below. Upper glume apex acuminate; muticous, or awned; 1 -awned. Upper glume awn 0–3 mm long.

FLORETS Fertile lemma oblong; 2–4 mm long; cartilaginous; without keel; 3 -veined. Lemma margins involute; interlocking with palea keels. Lemma apex entire, or dentate; 2 -fid; acute; awned; 1 -awned. Principal lemma awn apical, or from a sinus; geniculate; 7–13 mm long overall; with twisted column. Column of lemma awn 1–3 mm long. Palea with auriculate flaps; 1 length of lemma; cartilaginous; 2 -veined. Palea keels winged (below); narrowly winged.

FLOWER Lodicules 2; cuneate; fleshy.

DISTRIBUTION Asia-temperate: China. Asia-tropical: India and Malesia.

NOTES Arundinelleae. Gould.
