Leaves linear or narrowly spatulate, aromatic, sessile, 0.5–3.5 cm long, 0.2–0.6 cm wide, base cuneate, margins entire to dentate with few teeth, often revolute, apex obtuse, lanate but glabrescent, glandular, 1-nerved. Capitula axillary, 1–2 mm long, in contracted racemes or glomerules, immersed in a mass of lanuginose hairs; stalks of individual capitula absent or up to 0.5 mm long; receptacle convex, naked; phyllaries 2-seriate, subequal, scarious, lanceolate, 1.2–2 mm long, margins fimbriate, acuminate. Outer florets yellow, 30–40, tube filiform, 0.6–0.9 mm long, style 0.8–1.1 mm long, briefly bifid; inner florets yellow, 3–6, tube narrowly infundibuliform, 0.7–0.9 mm long, minutely and sparsely glandular, lobes 0.2–0.4 mm long; anthers ± 0.6 mm long with caudate tails and filiform distal appendages; style ± 0.8 mm long with very short clavate arms. Achenes narrowly obovoid, 0.5–0.8 mm long, glandular-puberulous; pappus of outer florets a minute serrulate corona, of inner florets a minute corona of scales sometimes with an inner row of 4–7 barbellate bristles 0.6 mm long (rarely in EA material). (from JSTOR Global Plants website / Flora of Tropical East Africa) Annual herbs. Leaves alternate, linear, sessile, mucronate, woolly hairy (hair type B) and glandular-hairy, margin flat, dentate. Capitula disciform, few together in small clusters. Involucral bracts in few rows, cartilaginous, woolly hairy; stereome divided. Receptacle flat, epaleate. Female florets yellow, filiform, in several rows, more than disc florets. Discflorets bisexual; corolla yellow, tubular; lobes erect. Anthers ecalcarate, caudate; endothecial tissue polarised; apical appendage flat, narrower than thecae. Style bifid; style branches truncate with apical tuft of obtuse sweeping hairs; stigmatic surface separated.
