Fargesia murielae

HABIT Perennial; caespitose. Rhizomes short; pachymorph. Culms 200–400 cm long; 7–10 mm diam.; woody. Culm-internodes terete; 20 cm long. Lateral branches dendroid. Branch complement several; in a horizontal line; with subequal branches; thinner than stem. Culm-sheaths 10–12 cm long; hairy on margins. Culm-sheath blade linear; reflexed; 4–6 cm long. Leaf-sheaths striately veined; glabrous on surface. Leaf-sheath oral hairs scanty; deciduous. Ligule a ciliolate membrane; 1 mm long. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.3–0.4 cm long. Leaf-blades lanceolate; 7–12 cm long; 10–15 mm wide. Leaf-blade venation with 8–10 secondary veins; with distinct cross veins. Leaf-blade surface smooth, or scabrous; rough adaxially. Leaf-blade apex attenuate.

INFLORESCENCE Inflorescence composed of racemes; subtended by a spatheole; embraced at base by subtending leaf. Spatheole elliptic; 3–5 cm long.

Racemes 1; single; oblong; unilateral; 2–3 cm long. Spikelet packing crowded; irregular.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 3–5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 12–20 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 10–13 mm long; chartaceous; without keels. Lower glume surface puberulous. Lower glume apex attenuate; awned; 1 -awned. Lower glume awn 2 mm long. Upper glume lanceolate; 9–11 mm long; chartaceous; without keels; 3 -veined. Upper glume surface puberulous. Upper glume apex attenuate; awned; 1 -awned. Upper glume awn 4 mm long.

FLORETS Fertile lemma lanceolate; 8–11 mm long; chartaceous; without keel; 5 -veined. Lemma surface puberulous. Lemma apex attenuate; awned; 1 -awned. Principal lemma awn 2 mm long overall. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 3. Anthers 3. Stigmas 3.

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION Asia-temperate: China.
