Type
Type: Madagascar, ‘dans les marais’, Du Petit-Thouars s.n. (P, holo.)
Morphology General Habit
Perennial herb 25–90 cm tall, stoloniferous, with culms crowded in small tussocks, sometimes with a thick erect rhizome.
Morphology Culms
Culms rounded, 4-angular or triangular, sometimes twisted, 1–5 mm thick, ridged distinctly or obscurely.
Vegetative Multiplication Stolons
Stolons to 30 cm long, 1.5–2.5 mm across, with 5–15 mm long grey-black scales at internodes.
Morphology Leaves Leaf sheaths
Sheaths grey, green or purple, ± 3 above the prophyll, ending in a triangular greyish lobe
Morphology Reproductive morphology Inflorescences
Inflorescence a cylindric spike 10–55 mm long and 2.5–5 mm across. Inflorescence bracts green at base, grey at apex, shorter than glumes.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes reddish or purple with green or yellow mid-area and transparent upper margins, rarely all green or grey, 3–5 mm long, obtuse but often frayed
Morphology Reproductive morphology Flowers Perianth
Perianth segments usually 7–8 reddish bristles longer than the nutlet, with many recurved teeth, or bristles fewer, hardly developed to absent
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 3, white
Morphology Reproductive morphology Flowers Gynoecium Style
Style branches 2–3
Morphology Reproductive morphology Fruits
Nutlets brown when mature, urn-shaped and biconvex, 1.4–1.9 × 1.1–1.5 mm (excepting the appendage), finely ribbed and reticulate between ribs; appendage darker, conical.
Ecology
Lake margins, swampy grassland, seasonally flooded grassland, papyrus swamps and Sphagnum bogs; (0–)750–1200 m
Note
Haines & Lye say Eleocharis nupeensis Hutch. occurs in T 8, and they cite Milne-Redhead & Taylor 10917 from Hanga Farm. They state it is “close to variegata but differs in being more slender and nutlets narrower above, and with very large light appendage”. Svenson in Rhodora 41: 6 (1939) mentions the great complexity of the E. fistulosa/nupeensis/mutata/ variegata/calocarpa group. He does not cite any specimens from East Africa; I have not seen any, either, though I have searched the Kew collections for the cited specimen. This will have to remain a mystery taxon, for our area.
Distribution
Range: Sierra Leone, Guinea, Nigeria, Congo-Kinshasa, Angola, Zambia, Zimbabwe, Botswana; Madagascar, Indian Ocean islands Flora districts: U3 U4 T2 T4 P

Note
Svenson in Rhodora 41: 6 (1939) cites Hancock & Chandler 21 from U 4, Mengo District: Kampala, and Chandler 1393 from Masaka District for this taxon. The taxon is very close to variegata, Svenson says. I believe both these specimens are E. variegata.
