Ecology and Distribution :
Tropical Africa
Biology :
Perennial herb 0,3-0,8-1,5 (tropical material) m tall; rhizome creeping, fleshy, with a tough persistent central core, with underground spherical-elliptical tubers 1,5-2x1,2-1,5 cm; stems single, sharply trigonous; lower leaf sheaths with an elongate V-shaped mouth without a projecting tongue; leaves shorter to longer than stem; blade 3-7 per stem, to 60 cm long, 0,4-1 cm wide; inflorescence simple or compound consisting of a central group of clustered ± sessile red to purple spikelets, accompanied by 2-6(-14) rays each to 3,5-5 cm long and wide; the whole inflorescence pseudo-lateral but later expanding to appear terminal; involucral bracts 1-2(-3), leaf-like.
Ecology :
A freshwater plant, frequently along streams, river sides and lake shores, semi-desert swamps, marshes; saline conditions; black mud; often associated with human settlements; also planted as waterfowl food, rice agriculture (Naczi & Ford, Sedges: uses…: 68, 2008); 0-1500 m alt. (S. Africa). Variable in inflorescence structure, the morphotypes may be influenced by habitat conditions (cf. Amini Rad in Nord. J. Bot. 28: 592, 2010; and Browning & al., ibid. 18: 479, 1998). The holotype of Scirpus glaucus Lam. (“Senegal, Roussilon s. n. in P-Herb. Lamarck 673 /14”) was not seen by Amini Rad & al. (o.c.). J. Raynal determined this specimen as Scirpus maritimus (Nord. J. Bot. 18: 478, 1998).
