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

Type
Type: ‘habitat in India orientali’, König s.n. (LINN 71.42, lecto., chosen by Gordon-Gray in Strelitzia 2: 136, 1995)
Morphology General Habit
Perennial, sometimes resembling annuals, 15–120 cm tall, with a swollen culm-base and usually a short woody rhizome.
Morphology Culms
Culms tufted/few, 6–90 cm long, 0.5–5 mm in diameter, bluntly trigonous, glabrous
Morphology Leaves
Leaves with lowermost leaf sheaths dark red to purple, upper ones green to pale brown, the basal scales often splitting up into fibres; blade linear, flat or with central v-section, 10–39 cm long, 2–9(–12) mm wide, attenuate, scabrid on margin and midrib near apex
Morphology Reproductive morphology Inflorescences Bracts
Involucral bracts erect to spreading. Leaf-like, 4–15, lowermost 5–30 × 0.2–1.2 cm
Morphology Reproductive morphology Inflorescences
Inflorescence a simple anthela with 4–18 primary branches 0.2–12 cm long, sometimes with 1–6 sessile spikes at base of some stalked spikes. Spikes cylindrical, 0.7–3 × 0.5–1.3 cm, with 25–180 spreading spikelets.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets green, sometimes yellowish green when young, flushed brown to golden when older, 2.5–7 mm long, 1–4-flowered, rachilla straight. Spikelets falling off entirely when mature.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes pale green with green keel, ovate, 2–3.5 × 0.6–1 mm, with 4–6 veins on either side, acute or obtuse
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 3.
Morphology Reproductive morphology Flowers Androecium Stamens Anthers
Anther 0.5 mm long
Morphology Reproductive morphology Flowers Gynoecium Style
Style 3-branched
Morphology Reproductive morphology Fruits
Nutlet reddishbrown, ellipsoid, 1.5–1.9 × 0.6–0.8 mm, trigonous, minutely papillose
Figures
Fig. 34, p224
Ecology
Forest clearings and pathsides, grassland, woodland, especially in swampy situations or streamsides, also in (post-)cultivation areas; may be locally common, forming clusters or small tussocks; 0–1900(–2200) m
Conservation
Common and widespread; least Concern (LC)
Note
As is usual with common and widespread pioneer taxa, a whole host of subspecies and varieties has been recognized in the past. Lye was doubtful about the status of three of the varieties (“it is doubtful if this variety is worth retaining/it is somewhat doubtful if this variety is worth retaining/like the previous two varieties it is of somewhat doubtful status” and then went on to combine another three previous names as subspecies of C. cyperoides. Here I also lump these taxa into the main body, helped by the fact that Lye already stated “this subspecies is not always easily recognized/however, there are many intermediate forms/intermediate forms are, however, by no means rare”. I see this taxon as a single, rather variable species, with various forms influenced by habitat, amount of moisture available and time of the season.
