- Morphology General Habit
- Perennial, slender, up to 31 cm tall, with short rhizome and small swollen culmbases covered by fibrous remains of old leaf sheaths.
- Morphology Culms
- Culms 15–30 cm long, 0.3–0.7 mm wide, bluntly triangular, glabrous below, minutely hairy above
- Morphology Leaves
- Leaves 2–3 per culm, up to 8 cm long. Leaf blade linear, 1–8 cm long, 1–2 mm wide, densely hairy on lower surface and along margin Leaf sheath green to reddish-brown, villous.
- Morphology Reproductive morphology Inflorescences Bracts
- Involucral bracts leaf-like to bract-like, spreading, 2, lowermost 0.6–1.6 cm long, minutely hairy particularly along the margin and on midrib below
- Morphology Reproductive morphology Inflorescences
- Inflorescence a small white (tinged with pale green or purplish) globose head 4–6 mm in diameter, of a single spike.
- Morphology Reproductive morphology Inflorescences Spikelets
- Spikelets lanceolate, 2.5–3 mm long, 0.6–0.8 mm wide, 2–3-flowered.
- Morphology Reproductive morphology Inflorescences Bracts Glume
- Glumes whitish, ovate, 2.3–2.6 mm long, keel slightly excurrent, hairy, with ± 3 veins on either side
- Morphology Reproductive morphology Flowers Androecium Stamens
- Stamens not seen
- Morphology Reproductive morphology Flowers Gynoecium Style
- Style 2–3-branched almost to base
- Morphology Reproductive morphology Fruits
- Nutlet ellipsoid to obovoid, flattened, 1.5–1.7 mm long, 0.6–0.8 mm wide, minutely papillose.
- Ecology
- Miombo woodland on red loam; ± 1080 m
- Conservation
- Data deficient (DD) – needs information on possible threats
- Note
- The branching of the style can be in 2 or in 3, and the nutlet flattened or slightly triangular; hence, the taxon can be seen as intermediate with Cyperus section Bulbocaulis. Culm and glumes. Similar to K. tanzaniae but distinct in its hairy leaves.
