Type
Type: Ethiopia, Kouaieta, Quartin Dillon s.n. (P, holo.)
Morphology General Habit
Annual, up to 33 cm high.
Morphology Culms
Culms tufted, 12–31.5 cm long, 0.4–1 mm wide, trigonous, smooth
Morphology Leaves
Leaf blade narrowly linear to filiform, folded or canaliculate, glabrous, 5–17 cm long, 0.6–1.2 mm wide, apex acuminate, glabrous to minutely scabrid Leaves up to 20 cm long. Leaf sheath 2–4.5 cm long, brown.
Morphology Reproductive morphology Inflorescences Bracts
Involucral bracts leaf-like, canaliculate, the lowermost 5.6–13.5 cm long, 0.6–1.2 mm wide, glabrous, continuing in the direction of the culm, the inflorescence therefore appearing lateral
Morphology Reproductive morphology Inflorescences
Inflorescence capitate.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets sessile, 8–30 per head, linear-oblong to ellipsoid-oblong, 6–19.5 mm long, 1.3–2 mm wide, axis straight.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes ovate, glabrous, golden yellowish-brown, somewhat translucent, to dark (reddish-)brown, 1.3–1.7 mm long, 1–1.4 mm wide, keel rounded to acute, yellowish-green, 2–3veined, apex obtuse
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 2: filaments 0.7–1 mm long
Morphology Reproductive morphology Flowers Gynoecium Stigma
Stigma 2-branched
Morphology Reproductive morphology Fruits
Nutlet obtriangular, flattened but thicker over the shoulders, 0.6–1.1 mm long, 0.4–0.7 mm wide, minute tubercles in longitudinal rows, metallic reddish brown or greyish-black.
Ecology
In damp grassland and swampy area, often on rock outcrops, 1100–2040 m
Conservation
Least concern (LC) due to its wide distribution
Note
" P. capillifolius is a very distinct species, and does not seem closely related to any other species in the Flora area. It is one of few species with an appearantly lateral inflorescence, due to the lowermost involucral bract, which continues in the direction of the culm. Although several other species have an erect involucral bract as well, they do not show it as prominently as P. capillifolius.
Distribution
Flora districts: U3 K3 T1 T7 T8 Range: Senegal, Guinea, Sierra Leone, Liberia, Ghana, Nigeria, Central African Republic, Congo-Kinshasa, Burundi, Sudan, Ethiopia, Zambia, Malawi, Angola; Madagascar
