Key characteristics
Tall (>2m) and short (usually <1m) forms exist. Leaves broad but <5cm; spikelet <7mm.
Found in variety of open to semi-shaded habitats including savannah, swamps, cultivated fields (as a weed), secondary forest and rainforest usually near or in water.
Potentially useful traits
Salt tolerance
Can be a weed in rice fields.
