Neololeba inaurita
HABIT Perennial; caespitose; clumped densely. Rhizomes short; pachymorph. Culms erect; 400–800 cm long; 10–20 mm diam.; woody; without nodal roots. Culm-internodes terete; hollow; 50–60 cm long; mid-green; distally glabrous. Lateral branches dendroid; arising from upper culm. Bud complement 1. Branch complement one, or two, or three; in a clump; thinner than stem. Culm-sheaths deciduous; 11–12 cm long; 2 times as long as wide; hispid; with white hairs, or tawny hairs; truncate at apex; without auricles; setose on shoulders; shoulders with 15–19 mm long hairs. Culm-sheath blade triangular; narrower than sheath; erect; 8–10 cm long; 27–33 mm wide; glabrous on surface. Leaf-sheath oral hairs setose; 15–19 mm long. Leaf-sheath auricles absent. Ligule an eciliate membrane; 1–2 mm long. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades deciduous at the ligule; elliptic, or ovate; 14–42 cm long; 60–80 mm wide. Leaf-blade surface glabrous. Leaf-blade apex acuminate.
INFLORESCENCE Synflorescence bractiferous; clustered at the nodes; in untidy tufts; with spathaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets; leafless between clusters.
FERTILE SPIKELETS Spikelets comprising 5–6 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 15–19 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite; 1 mm long; glabrous.
GLUMES Glumes two; persistent; similar; shorter than spikelet; similar to fertile lemma in texture. Lower glume ovate; 8 mm long. Lower glume apex acuminate; mucronate. Upper glume ovate; 8 mm long. Upper glume apex acuminate; mucronate.
FLORETS Fertile lemma ovate; 9–11 mm long; without keel. Lemma surface glabrous. Lemma apex acuminate. Palea 9–11 mm long. Palea apex acute. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Anthers 6; 4 mm long; yellow. Stigmas 3.
FRUIT Caryopsis with adherent pericarp.
DISTRIBUTION Asia-tropical: Papuasia.
NOTES Bambuseae. Widjaja 2002.
