Description Perennial herb up to 180 cm tall with a short, woody rhizome. Culm 80–100 cm × 4–9 mm, robust, slightly compressed, smooth-grooved, tapering to the top. Basal leaves leathery; leaf blades 30–36 cm × 7–15 mm, flat or with inrolled edges, margins scabrid, tapering strongly above the leaf sheaths, very acute; leaf sheaths much broader, 8–10 × 3.5 cm, dark brown-purplish. Cauline leaves 3, up to c. 35 cm, widely spaced; sheaths scarcely enlarged brownish-green base brown, edge obliquely cut. Inflorescence a large panicle, 60–100 cm long, up to c. five to seven cm wide; inflorescence bracts 9–11, sheathing, dark brown-purple. Peduncles unequal, up to 12 cm long, quite robust, flattened, margins scabrid. Pedicels of the spikelets three to five mm long, flattened, margins scabrid, ± curved. Spikelets very numerous, linear-oblong, 7–10 × 1–1.5 mm. Glumes 16–18, pale reddish or light reddish brown with hyaline margins, obtuse, lower 14–16 empty, upper 2 fertile; lower empty glumes very small, increasing in size towards top of spikelet; top glume somewhat reduced, pale, narrow. Flowers 2, lower male or sterile, upper bisexual. Perianth bristles 6, two to three times as long as the nutlet including its beak, rust-coloured, long ciliate, plumose. Stamens 3; anthers linear, shortly apiculate. Style trifid, long, hispidulous, pale brown, base pyramidal or triangular persistent. Nutlet obovoid, quite strongly trigonous, with canaliculate ribs, 1.5 mm long, rugulose, reddish brown; beak one mm long. [details]

Distribution Endemic to Madagascar, occurring in the provinces Antananarivo, Fianarantsoa and Toamasina.
