Fargesia lincangensis

HABIT Perennial; caespitose. Rhizomes short (5–9cm); pachymorph. Culms 400–800 cm long; 20–50 mm diam.; woody. Culm-internodes terete; hollow; 25–45 cm long; distally glabrous. Culm-nodes with distinct supra-nodal ridge. Lateral branches dendroid. Branch complement several. Culm-sheaths persistent, or deciduous but leaving a persistent girdle; coriaceous; hispid; with yellow hairs, or tawny hairs; hairy on margins; without auricles, or auriculate; setose on shoulders; shoulders with straight hairs, or curved hairs; shoulders with 4–12 mm long hairs. Culm-sheath ligule 1–1.5 mm high; purple; ciliate. Culm-sheath blade linear, or lanceolate; deciduous; reflexed; glabrous on surface. Leaves 2–3 per branch. Leaf-sheaths glabrous on surface; outer margin glabrous, or hairy. Leaf-sheath oral hairs setose; 3–6 mm long; pale. Ligule an eciliate membrane; 1 mm long; purple; truncate. Leaf-blade base cuneate; with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 7–10 cm long; 12–16 mm wide; chartaceous. Leaf-blade venation with 6–10 secondary veins; with obscure cross veins. Leaf-blade surface glabrous. Leaf-blade margins smooth.

INFLORESCENCE Inflorescence a panicle; comprising 4–5 fertile spikelets; bracteate at branch bases; subtended by an inflated leaf-sheath; embraced at base by subtending leaf.

Panicle open; 8–12 cm long; bearing few spikelets.

Spikelets solitary. Fertile spikelets sessile and pedicelled. Pedicels 3–7(–10) mm long; glabrous.

FERTILE SPIKELETS Spikelets comprising 5–8 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 25–55 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes (3–)4–8 mm long; pubescent.

GLUMES Glumes shorter than spikelet. Lower glume lanceolate; 3–10 mm long; 0.33–0.75 length of upper glume; 3 -veined. Lower glume apex acuminate. Upper glume lanceolate; 9–13 mm long; 0.9 length of adjacent fertile lemma; 5 -veined. Upper glume apex acuminate.

FLORETS Fertile lemma lanceolate, or ovate; 10–15 mm long; without keel; 7 -veined. Lemma lateral veins with cross-veins. Lemma margins ciliolate. Lemma apex setaceously attenuate. Palea 7–11 mm long. Palea apex dentate; 2 -fid. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 3; lanceolate; 2–3 mm long; ciliate. Anthers 3; 5–6 mm long; yellow. Stigmas 2. Ovary glabrous.

DISTRIBUTION Asia-temperate: China.
