Morphology General Habit
Perennial; caespitose. Rhizomes short; pachymorph. Culms erect; 2000-3000 cm long; 200-300 mm diam.; woody. Culm-internodes terete; thin-walled; 30-45 cm long. Lateral branches dendroid. Branch complement many; with 1 branch dominant; thinner than stem. Culm-sheaths deciduous; coriaceous; purple; pubescent; hairy throughout; with dark brown hairs; auriculate; glabrous on shoulders. Culm-sheath ligule 6-12 mm high; ciliate and dentate. Culm-sheath blade lanceolate; spreading. Leaves 5-15 per branch. Ligule an eciliate membrane; 3 mm long; erose. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 15-45 cm long; 30-60 mm wide. Leaf-blade venation with distinct cross veins. Leaf-blade margins scabrous.
Morphology Reproductive morphology Inflorescences
Synflorescence bractiferous; clustered at the nodes; in stellate clusters; 2-2.5 cm long; dense; with glumaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets; leafless between clusters. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 4-8 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 12-15 mm long; 3-4 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes suppressed between florets.
Fertile
Spikelets comprising 4-8 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 12-15 mm long; 3-4 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes suppressed between florets.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; dissimilar; shorter than spikelet. Lower glume orbicular; 0.7-0.8 length of upper glume; chartaceous; without keels; 13 -veined. Lower glume lateral veins with cross-veins. Lower glume apex acute. Upper glume oblate; 8-13 mm long; 1 length of adjacent fertile lemma; chartaceous; without keels; 15 -veined. Upper glume lateral veins with cross-veins. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile florets increasing in size upwards. Fertile lemma oblate; 8-13 mm long; chartaceous; without keel; 25 -veined. Lemma lateral veins with cross-veins. Lemma margins ciliate. Lemma apex acute. Palea 0.9 length of lemma; chartaceous; 6 -veined; 2-keeled but the uppermost without keels. Palea keels ciliate.
Morphology Reproductive morphology Flowers
Lodicules absent. Anthers 6; 7-10 mm long; anther tip apiculate. Stigmas 1. Ovary umbonate; pubescent all over.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; 7-8 mm long; hairy at apex.
Distribution
Africa: western Indian ocean. Asia-temperate: China and eastern Asia. Asia-tropical: India, Indo-China, and Malesia.
