Cyperaceae, K Hoenselaar, B. Verdcourt & H. Beentje. Hypolytrum, D Simpson. Fuirena, M Muasya. Flora of Tropical East Africa. 2010

Type
Type: Madagascar, Nosy Be [Nossibé], Boivin 1996 (P, holo.; K!, iso.)
Morphology General Habit
Tufted annual 15–50(–80) cm tall.
Morphology Stem
Stems up to 1.5 mm thick, deeply grooved, usually with dense short white spine-like hairs
Morphology Leaves
Leaves up to 20 cm long and 0.5 mm wide, flat and channeled, with similar spine-like hairs.
Morphology Leaves Leaf sheaths
Sheaths with slender hairs up to 15 mm long
Morphology Reproductive morphology Inflorescences
Inflorescence open and umbelliform with (10–)20–40(–60) spikelets; main inflorescence bracts 5–60 mm long, the longest much longer than the nearest spikelet, with long slender marginal hairs at the base and short spine-like hairs above.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets 3–7 mm long, 1–2 mm wide.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes reddish brown with pale midrib, broadly ovate, 1–2 mm long with translucent 0.2–0.3 mm wide margin with short hairs, obtuse to rounded at apex or lower ones shortly subulate or acuminate, midrib 3-veined, 1–2 mm wide
Morphology Reproductive morphology Fruits
Nutlet at first uncoloured but grey or yellow-brown at maturity, obovoid, 0.7–0.8 mm long, almost smooth or with a translucent surface layer which breaks up into square or circular scales, giving a sometimes tuberculate appearance; epidermal cells isodiametric with strongly sinuose walls.
Morphology Reproductive morphology Flowers Gynoecium Style
Style-base persisting as a brownish knob.
Ecology
Shallow soil over rock, grassland, seasonally moist hollows, cultivation, miombo woodland; 50—2000 m
Note
I am not certain of the Kenya Coast record. C.B. Clarke thought it matched his Bulbostylis coleotricha var. lanifera (Boeck.) C.B. Clarke but Bodard has suggested it is nearer B. abortiva and Hooper states it does not match West African lanifera.
Distribution
Range: Throughout tropical Africa and Madagascar Flora districts: U1 U2 U3 K3 K 7 (see Note)T2 T4 T6 T ?8
