Culms tufted, crowded, 4–20 cm tall, filiform, 0.3–0.4 mm thick, persistent after fruit has fallen; basal tubers small, entangled in roots, white with fleshy stems and branches, covered in tough short scales.
Morphology Leaves Leaf sheaths
Sheaths pale, without reddish base, ending in short triangular lobe
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets ovoid or obovoid, 2–5 × 1–2.5 mm, elongating to 5 mm in fruit.
Morphology Reproductive morphology Inflorescences
Inflorescence bracts similar to glumes.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes pale brown or pale greenish brown, 1–1.3 mm long, with or without distinct narrow green keeled midrib and paler margin, apex obtuse or emarginate

Morphology Reproductive morphology Fruits
Nutlet yellowish brown, urceolateobovoid, 0.5–0.7 × 0.3 mm, strongly 3-ribbed, smooth or minutely tuberculate; appendage brown, triangular-conical, set in conspicuous rim.
Ecology
Ponds and pools, seepage areas, seasonally swampy grassland; may be locally common; 850–1700 m
Note
Probably closest to E. nigrescens, but differs in the much paler glumes and the appendage to the nutlet. Our material is subsp. setifolia; E. setifolia (A. Rich.) J. Raynal subsp. schweinfurthiana (Boeck.) D.A. Simpson in K.B. 43(3): 428 (1988) differs from subsp. setifolia in the perianth bristles, which are at least half as long as the nutlet. It occurs from Senegal and Mali to Nigeria, Congo-Kinshasa and Sudan.
Distribution
Range: Senegal to Nigeria, Congo-Kinshasa, Sudan, Ethiopia, Zambia; Philippines, Australia, Brazil, Caribbean Flora districts: K4 T2 T4 T5 T7
