Spikelets 7–22 per cluster, sometimes ± many, lanceolate to ellipsoid-ovoid, 10–18 mm long, 3–4.6 mm wide, elongating when in fruit, axis straight. Spikelets in digitate clusters or on an elongated axis, sessile or at the end of primary branches; primary branches 3–6, 2.5–7.5 cm long, with a purple tubular prophyll at its base.

Stigma 2-branched
Morphology Reproductive morphology Fruits
Nutlet shiny greyish-black, broadly ellipsoid to obovoid-orbicular, 0.7–1.5 mm long, 0.6–1 mm wide, minutely punctuate to ± wrinkled
Ecology
Open swamp and grassland, on riverbanks and in ditches; 300–1950 m
Conservation
Least concern (LC) due to its wide distribution and habitat.
Note
A single specimen from Teso had been identified as Cyperus mortonii S.S. Hooper by Hooper herself; this was the basis of the inclusion of this taxon in P. unioloides by Haines & Lye. I believe this was a misidentification and that C. mortonii is not distributed in the Flora area; its type is from Ghana.
Distribution
Flora districts: U1 U3 U4 T4 T5 T7 T8 %pantropical
