Ecology and distribution
Trop. Afr.
Biology : Perennial herb with long stolons; culms 30-77 cm long, 1,2-3,3 mm Ø, trigonous, smooth; leaf sheaths pale yellow brown, 2-10 cm long, often spongy; blade linear, plicate, 16-34 cm x 2,6-7 mm, acute, apex almost glabrous to scabrid; inflorescence simple with primary branches 1-8, 1-15,5 cm long; spikelets in clusters on elongated axis, sessile and at end of primary branches; spikelets 5-23 per cluster, lanceolate, 1,3-3,5 cm x 2,4-5 mm.
Ecology : Wet depression in grassland; lake shores; bushland; sometimes on or at base of rocky outcrops; 700-1850 m alt.
  Sometimes confused with P. nitidus that is, however, a more robust plant with a massive base bearing scales and (old) leaf bases and with glumes having an obtuse to acute apex; in P. longistolon the glumes are mucronate and their sides fold inwards during maturation of the nutlet.
