Ecology and distribution
Trop. Afr.
Biology : Perennial herb sometimes with rhizome; culms tufted 21-39 cm long, 1,6-2,3 mm Ø, trigonous, smooth; leaves many at base; sheath pale brown, 1-8 cm long; blade stiff, linear, plicate, 5-20 cm x 1,5-5 mm, acuminate, apex scabrid; inflorescence densely capitate, spikelets sessile, many per head; spikelets ± linear, 7-25x2-3 mm.
Ecology : Seasonally wet grassland; lake shores; swamp edges; riverbanks and other damp open habitats; sometimes submerged; growing right in the water along with reeds, Pandanus welwitschii and ferns; 0-1650 m alt.
  Often confused with P. smithianus from Zaire. Very similar to that species, which has, however, thicker and coarser leaves and glumes. According to Fl. Trop. E. Afr., l.c., all specimens from that area have been wrongly named P. smithianus.
