Fargesia pauciflora
HABIT Perennial. Culms 40 cm long; 3 mm diam.; woody. Culm-internodes terete; 4.5–9.5 cm long; distally glabrous. Lateral branches dendroid. Leaves 3–6 per branch. Leaf-sheaths glabrous on surface; outer margin glabrous, or hairy. Leaf-sheath oral hairs setose; dark. Ligule an eciliate membrane; 0.5 mm long; truncate. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 1–3 cm long; 3–6 mm wide. Leaf-blade venation with 4–6 secondary veins; with distinct cross veins. Leaf-blade surface pubescent; hairy adaxially. Leaf-blade margins scabrous. Leaf-blade apex acuminate.
INFLORESCENCE Inflorescence composed of racemes; without bracts, or bracteate at pedicel base; subtended by a spatheole; embraced at base by subtending leaf.
Racemes 1; single; 2–3 cm long; bearing 3 fertile spikelets on each.
Spikelets solitary. Fertile spikelets pedicelled. Pedicels 2–4 mm long; smooth.
FERTILE SPIKELETS Spikelets comprising 4–5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 16–21 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2.5–4 mm long; pilose. Floret callus pubescent.
GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume ovate; 3–4 mm long; chartaceous; without keels; 1–3 -veined. Lower glume lateral veins absent, or distinct. Lower glume margins eciliate, or ciliolate. Lower glume apex acute. Upper glume ovate; 6–7.5 mm long; chartaceous; without keels; 7–9 -veined. Upper glume margins eciliate, or ciliolate. Upper glume apex acute.
FLORETS Fertile lemma lanceolate, or ovate; 8–12 mm long; chartaceous; without keel; 7–9 -veined. Lemma lateral veins with cross-veins. Lemma surface glabrous, or puberulous; hairy on veins. Lemma apex acuminate. Palea 7–8 mm long. Palea keels ciliolate; adorned above. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Lodicules 3; 1.5–2 mm long; veined; ciliate. Anthers 3; 5 mm long. Stigmas 2–3. Ovary glabrous.
FRUIT Caryopsis with adherent pericarp.
DISTRIBUTION Asia-temperate: China.
