Morphology General Habit
Perennial; caespitose. Rhizomes short; pachymorph. Culms erect; 600-1500 cm long; 25-75 mm diam.; woody; without nodal roots, or with prop roots. Culm-internodes terete; solid; 30-45 cm long. Culm-nodes swollen. Lateral branches dendroid. Branch complement many; with 1 branch dominant; thinner than stem. Culm-sheaths deciduous; 0.25-0.66 length of internode; coriaceous; hispid; hairy throughout; with dark brown hairs; auriculate; ciliate on shoulders. Culm-sheath blade lanceolate; acuminate. Ligule an eciliate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades linear, or lanceolate; 2.5-25 cm long; 5-30 mm wide. Leaf-blade venation with distinct cross veins. Leaf-blade surface scabrous; rough adaxially; pubescent; hairy abaxially, or on both sides. Leaf-blade margins scabrous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Synflorescence bractiferous; clustered at the nodes; in globose clusters; 1.5-4 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 2-3 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 7.5-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes suppressed between florets.
Fertile
Spikelets comprising 2-3 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 7.5-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes suppressed between florets.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet. Lower glume ovate; chartaceous; without keels. Lower glume apex acuminate. Upper glume ovate; chartaceous; without keels. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets
Fertile florets increasing in size upwards. Fertile lemma ovate; 8 mm long; chartaceous; without keel. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn pungent; 2 mm long overall. Palea ovate; 0.9 length of lemma; chartaceous; 6-9 -veined; 2-keeled but the uppermost without keels. Palea keels ciliate.
Morphology Reproductive morphology Flowers
Lodicules absent. Anthers 6. Stigmas 1. Ovary umbonate; pubescent on apex.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; ovoid, or orbicular; 8 mm long; hairy at apex; apex rostrate.
Distribution
Africa: western Indian ocean. Asia-temperate: eastern Asia. Asia-tropical: India, Indo-China, and Malesia. Pacific: northwestern.
