    Spikelets
    Spikelets sessile, 2-flowered, terete or somewhat laterally compressed, muticous subtended by a pseudo-involucre of broad coriaceous bracts; florets both hermaphrodite; rhachilla disarticulating beneath the superior glume, produced as a fine bristle beyond the superior floret.
    Glume
    Inferior glume absent; superior glume 11-18-nerved, dorsally rounded, chartaceous to coriaceous, with the margins involute.
    Lemma
    Lemmas exceeding the glumes, many-nerved (11-23), with transverse veinlets, imbricate, dorsally rounded, chartaceous to chartaceous-coriaceous.
    Palea
    Paleas slightly shorter than the corresponding lemmas, 5-11-nerved, 2-keeled, flat between the keels.
    Lodicules
    Lodicules absent.
    Stamens
    Stamens 6; filaments free, anthers distinctly mucronate.
    Pistil
    Ovary pilose at the apex; stigma 1.
    Fruits
    Caryopsis crustaceous, with a free pericarp, with a pilose apical appendage.
    Habit
    Tall woody bamboos.
    Leaf lamina
    Leaf-laminae finally disarticulating from the sheath.
    Inflorescences
    Inflorescence narrow, slender, large, composed of clusters of spikelets on opposite sides of its branches; each cluster borne in the axil of a deciduous sheath which is usually without a lamina.

    Habit
    Bamboo with woody culms
    Leaves
    Leaf-blades disarticulating from the sheaths
    Inflorescences
    Inflorescence large, loose, the spikelet-clusters alternate on opposite sides of its branches, each cluster arising in the axil of a deciduous bladeless or short-bladed sheath, it and the individual spikelets subtended also by broad coriaceous bracts, their outer sides forming a sort of involucre
    Spikelets
    Spikelets 2-flowered, both florets hermaphrodite, awnless, terete or slightly laterally compressed; rhachilla disarticulating only beneath the upper glume, produced as a fine bristle beyond the upper floret; lower glume absent; upper glume rounded on the back, convolute, coriaceous or papyraceous; lemmas exceeding the glumes, imbricate, convolute, rounded on the back, 11–23-nerved with transverse veinlets, papyraceous to thinly coriaceous; palea 5–11-nerved, 2-keeled, flat between the keels; lodicules 0; stamens 6, anthers mucronate, filaments free; ovary hairy at the tip, stigma 1
    Fruits
    Grain with free pericarp and crustaceous hairy apical appendage
    Distribution
    Species 1; Africa.

    Habit
    Perennial. Rhizomes short; pachymorph. Culms geniculately ascending; 450-1800 cm long; woody. Lateral branches dendroid. Branch complement two, or three; in an irregular line; with 1 branch dominant. Culm-sheaths without auricles. Culm-sheath blade linear. Ligule an eciliate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades deciduous at the ligule; lanceolate, or oblong. Leaf-blade venation with obscure cross veins.
    Inflorescences
    Synflorescence bractiferous; clustered at the nodes; in oblong clusters; with spathaceous subtending bracts; with axillary buds at base of spikelet; leafless between clusters.
    Spikelets

    Fertile
    Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; laterally compressed, or subterete; 12-15 mm long; falling entire.
