Garnotia yunnanensis

HABIT Annual; caespitose. Culms erect; 20–60 cm long; 1–1.5 mm diam. Culm-nodes glabrous. Lateral branches lacking, or sparse. Leaf-sheaths mostly shorter than adjacent culm internode; smooth; glabrous on surface. Ligule an eciliate membrane, or a ciliolate membrane; 0.7 mm long. Leaf-blades linear; 5–13 cm long; 3–6 mm wide. Leaf-blade surface glabrous, or pilose; sparsely hairy; hairy adaxially.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear; 6–23 cm long. Primary panicle branches appressed; 3–4 -nate; 4–8 cm long; bearing spikelets almost to the base.

Spikelets in pairs. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 3–5 mm long; falling entire.

GLUMES Glumes similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 1 length of spikelet; membranous; 1-keeled; 3 -veined. Lower glume surface scabrous; rough on veins. Lower glume apex obtuse; mucronate, or awned; 1 -awned. Lower glume awn 0.5–3 mm long. Upper glume lanceolate; 1 length of spikelet; membranous; 1-keeled. Upper glume surface scabrous; rough on veins. Upper glume apex obtuse; mucronate, or awned; 1 -awned. Upper glume awn 0.5–3 mm long.

FLORETS Fertile lemma oblong; cartilaginous; without keel; 3 -veined. Lemma lateral veins obscure. Lemma margins involute; interlocking with palea keels. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; straight, or geniculate; 9–11 mm long overall; without a column, or with a straight or slightly twisted column. Column of lemma awn 2 mm long. Palea cartilaginous.

DISTRIBUTION Asia-temperate: China.
