Description: | Perennial herb, sometimes with slightly woody base, 5–30 cm high, much-branched; stems glandular and scabridulous-hairy. Leaves linear to narrowly obovate, 0.5–3.5(–5) x 0.1–0.3 cm, base cuneate or attenuate, margin entire or with few teeth, apex obtuse and mucronate, acute or 3-toothed, viscid-glandular and scabridulous on both surfaces. Capitula solitary on small branches but these forming small to large lax leafy corymbs; involucre 5–10 mm long; phyllaries green with yellow tips, pointing upwards, after achenes have fallen reflexed, lanceolate, 2–10 mm long, acute, scabridulous and glandular. Florets pale yellow, 14–30, all bisexual, 3.3–5.2 mm long. Achenes cylindric, 3.7–4.5 mm long, ribbed, pilose and sparsely glandular; pappus white, 5–6 mm long, plumose, with an outer row of deeply incised scales to 2 mm long.

Capitula 5–13 mm long, solitary on small branches but these forming small to large, lax, leafy corymbs; phyllaries green with yellow tips, porrect, after achenes have fallen reflexed, lanceolate, 2–10 mm long, acute, scabridulous and glandular; receptacle honeycombed, with triangular bumps to 0.3 mm long. Florets pale yellow, 14–30, all hermaphrodite, tube cylindric, 3.2–5 mm long, sparsely glandular, lobes 0.1–0.2 mm except for a single adaxial one which is 1.3–1.5 mm long, glandular, anthers 2.3–2.5 mm long, style 6–6.5 mm long.

(from JSTOR Global Plants website / Flora of Tropical East Africa) Annual, paniculately branched, scaberulous, with short crisp hispid hairs, subglutinous above, 0.333–2 ft. high; branches subterete, striate. Leaves linear or oblanceolate, deltoid or subacute at apex, usually apiculate, gradually narrowed towards the base, sessile, entire or with a few irregular remote teeth above,0.5–1.333 in. long by 0.0625– 0.3125 in. wide; uppermost smaller, bract-like, subulate.

Scales of the involucre pauciseriate, acute, falling short of the florets; inner linear-lanceolate, with scarious margins; outer shorter, linear-subulate, often recurving.
