Culms tufted, 25–120 cm long, 0.8–1.3 mm wide, rounded to trigonous, with longitudinal grooves, smooth, when young culms erect, when mature culms often curving and eventually the inflorescence touching the ground
Morphology Leaves
Leaves up to 14 cm long. Leaf blade absent, the sheath ending in a short triangular limb Leaf sheath greyish-black to purple, 1.5–14 cm long.
Morphology Reproductive morphology Inflorescences Bracts
Involucral bracts culm-like, erect, 1–2, 0.5–2 mm long, 1–1.5 mm wide
Morphology Reproductive morphology Inflorescences
Inflorescence capitate.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets in a digitate crowded head, 2–11(–20) per head, ovoid-lanceolate, 5.6–16(–28) mm long, 3.5–6 mm wide, rachis straight.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes reddish-brown, ovate to boat-shaped, 3.3–5.5 mm long, 1.7–2.4 mm wide, keel green, 3-veined, scabrid, apex obtuse to acute
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 3.
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Filaments 3.5–4.4 mm long.
Morphology Reproductive morphology Flowers Androecium Stamens Anthers
Anthers 1.4–1.8 mm long
Morphology Reproductive morphology Fruits
Nutlet surrounded by spongy yellow, corky tissue, 2.7–4 mm long, 0.8–1.3 mm wide, nutlet itself (visible part) brown, lanceolate, 1.4–2 mm long, 0.5–0.8 mm wide, smooth
Figures
Fig. 24, p152. Fig. 27, p169
Ecology
In swamps, lake edges, and in stagnant shallow water, sometimes floating; 750–2300 m
Conservation
Least Concern (LC) due to its wide distribution
Note
This species is closely related to C. colymbetes. Both species have nutlets surrounded by corky tissue to make them long-floating. The culms of C. pectinatus however are higher in number and much more slender than those of C. colymbetes, and are rounded to trigonous, whilst those of C. colymbetes are almost winged.
Distribution
Range: Widespread in west and central Africa down to South Africa Flora districts: U2 U4 K6 T2 T3 T4 T7
