Throughout the Old World Tropics. Africa: Angola, Botswana, Central African Republic, Equatorial Guinea, Ethiopia, Ghana, Kenya, Mali, Malawi, Mozambique, Namibia, Nigeria, Senegal, Somalia, Tanzania & Uganda. Eastern Asia to Indo-China, Malay Islands, Philippines & Northern Australia.
Ecology
Water holes, swamps, lake & lagoon margins; alt. 0 – 1300 m.
Morphology Culms
Culms, few to many closely packed, 5 – 50 cm long (including overtopping erect, inflorescence bract), 0.4 – 1.8 mm wide, ridged, triangular to almost terete
Morphology General Habit
Annual, tufted
Morphology Leaves
Leaves sheaths 1 – 2 cm long, often lowest enclosing basal female floret, style 3-branched, 15 – 20 mm long, basal nutlet wrinkled, 2 – 2.5 × 1.4 – 2 mm, blades absent or if present up to 30 cm long, flat or folded
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 3
Morphology Reproductive morphology Flowers Gynoecium Style

Morphology Reproductive morphology Flowers Perianth
Perianth absent
Morphology Reproductive morphology Fruits
Aerial nutlet, broadly ovoid, trigonous or weakly so, turning black at maturity, 1.1 – 1.4 × 0.8 – 1.3 mm, surface markedly rugose.
Morphology Reproductive morphology Inflorescences
Inflorescence consisting of clusters of spikelets, appearing pseudolateral, overtopped by inflorescence bract, shorter than culm
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes 2 – 3 mm long, ovate to broadly boat-shaped, pale brown with reddish streaks, green midrib, mucronate, margin ciliate apically
Morphology Reproductive morphology Inflorescences Spikelets
