Gigantochloa kuring

HABIT Perennial; caespitose. Rhizomes short; pachymorph. Culms erect; 2000–2500 cm long; 20–70 mm diam.; woody. Culm-internodes terete; with small lumen; 30–50 cm long; mid-green and yellow, or purple; striped; distally pruinose and pilose (when young). Lateral branches dendroid. Culm-sheaths persistent; 10.5–16 cm long; hispid; with appressed hairs; with black hairs; convex at apex; auriculate; with obtuse auricles; with 4 mm high auricles; setose on shoulders; shoulders with 7 mm long hairs. Culm-sheath ligule 2–3 mm high; dentate. Culm-sheath blade ovate; narrower than sheath; reflexed; 4.5–14.5 cm long; 15–35 mm wide; pubescent (sparsely). Leaf-sheath oral hairs setose; 3 mm long. Leaf-sheath auricles falcate; 1–2 mm long. Ligule a ciliate membrane. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 12–24 cm long; 16–22 mm wide. Leaf-blade surface glabrous.

INFLORESCENCE Synflorescence bractiferous; clustered at the nodes; in stellate clusters; dense; with glumaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets; leafless between clusters.

Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 3–4 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 10–17 mm long; breaking up at maturity; disarticulating above glumes but not between florets. Rhachilla internodes suppressed between florets.

GLUMES Glumes two; persistent; similar; shorter than spikelet. Lower glume ovate; 6–8 mm long. Lower glume margins ciliate. Lower glume hairs tawny. Lower glume apex acuminate; mucronate. Upper glume ovate; 6–8 mm long. Upper glume margins ciliate. Upper glume hairs tawny. Upper glume apex acuminate; mucronate.

FLORETS Fertile florets increasing in size upwards. Fertile lemma ovate; 9–13 mm long; chartaceous; without keel. Lemma margins ciliate. Lemma hairs tawny. Lemma apex acuminate. Palea 8–12 mm long; 2-keeled. Palea keels ciliolate. Palea apex dentate; 2 -fid. Apical sterile florets 1 in number; barren (without palea); lanceolate.

FLOWER Lodicules absent. Anthers 6; 5–6 mm long; red. Filaments united in a tube. Stigmas 1; pubescent.

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION Asia-tropical: Malesia.
