Ecology and distribution
Trop. Afr.
Biology : Perennial herb 0,2-1,3 m tall; rhizome creeping, with stolons terminating in tubers 1-1,5 cm Ø; culms tufted from a contracted base, bright green, rounded (rarely 4-angled), hollow, 4-8 mm Ø, septate at 3-10 cm intervals, contracted immediately below spikelet; leaf sheaths to 1/2 or 1/3 of culm height, ending in a triangular lobe; spikelet pale green, cylindric, 2,5-5 cm long, 2-6 mm Ø, narrower than culm.
Ecology : Swamps; shallow parts of lakes; in deeper parts of marshes close to open water; at wooded ponds by river; river banks; edges of mangroves; humid rice fields; ponds, often in standing water, submerged or forming floating mats; sometimes locally common or forming pure stands; sometimes in salt or brackish water; 0-2170 m alt. – Troublesome in irrigated crops.
  Variable species: stems and spikelets may be very short and narrow, perhaps due to dry habitat conditions.
