Morphology General Habit
Herb 20–60 cm tall; stems erect, leafy in lower part, thickly tomentose, glabrescent.
Morphology Leaves
Leaves sessile, the lower (broadly) obovate or oblong, 6–27 cm long, 4–13 cm wide, narrowing into a narrow, basally ± expanded subauriculate semi-amplexicaul somewhat sheathing base, margins dentate to coarsely dentate-serrate or crenate-serrate, apex rounded, obscurely acuminate, green, thinly araneose on both surfaces, more thickly so on margins and veins beneath; becoming smaller, oblong and relatively narrower towards the upper part of the stem, the uppermost 5–8 cm long and 1.5–2.5 cm wide.
Morphology Reproductive morphology Inflorescences Capitulum
Capitula 3–31 in narrow terminal strictly-branching racemiform thyrses, on short to elongated peduncules; involucre broadly cylindrical, dark in colour, 13–17 mm long, 5–12 mm wide; phyllaries ± 40, 6–7-seriate, broadly elliptic-oblong to narrowly oblong with the innermost narrower, rounded with dark membranous minutely fimbriate and ± erose margins, glabrescent, the longest 12.5–14 mm long.
Morphology Reproductive morphology Flowers Florets
Florets ± 20–25, white or cream; corolla 15–16.5 mm long, lobes 4–5 mm long, anthers brown.
Morphology Reproductive morphology Fruits
Achenes 5–7 mm long, pilose; pappus very pale stramineous, 11–13 mm long, bristles finely toothed.

Compositae, G. V. Pope. Flora Zambesiaca 6:1. 1992

Morphology General Habit
An erect often subscapose suffrutex 50–80 cm. tall, from a woody rootstock with many thong-like roots.
Morphology Stem
Stems annual, usually solitary, simple, ± densely leafy towards the base, leafless above, somewhat compressed-angular, araneose-lanate.
Morphology Leaves
Leaves concolorous, chartaceous-membranous, not stem-sheathing at the base; mostly 6–27 x 3.5–10 cm., broadly elliptic to broadly oblong-obovate, rounded to obtuse at the apex, sometimes subacute-apiculate, broadly cuneate below ± narrowing into a winged petiole-like midrib 0–30 mm. long, narrowly semi-amplexicaul sometimes subauriculate at the base; margins serrate to coarsely irregularly serrate, sometimes subentire; sparsely finely araneose-lanate on both surfaces, sometimes with scattered patent hairs on the upper surface; main nerves 10–12 on each side of the midrib.
Morphology Reproductive morphology Inflorescences Capitulum
Capitula 3–31 in a racemose to subpaniculate arrangement, 1–5 on short racemose branches from bract axils, capitula stalks stout 1–50 mm. long.
Morphology Reproductive morphology Inflorescences Bracts Involucre
Involucres mostly 13–20 x 5–12 mm., hardly spreading, narrowly cylindric.
Morphology Reproductive morphology Inflorescences Bracts Phyllaries
Phyllaries dark-purple sometimes stramineous, appressed imbricate, rounded obtuse, scarious-membranous, margins broadly hyaline ± torn, glabrous, from c. 2 mm. long and ovate outside, increasing to c. 19 mm. long becoming linear inside; middle phyllaries up to c. 6 mm. wide and oblong-ovate; inner phyllaries narrower.
Morphology Reproductive morphology Flowers Florets
Florets many; corollas yellowish-white, up to c. 19 mm. long with a long slender tube abruptly dilated into a short cylindric deeply-lobed limb which exceeds the pappus and involucre, glabrous; corolla lobes c. 4 mm. long, linear.
Morphology Reproductive morphology Fruits
Achenes to c. 7 mm. long, subfusiform-cylindric, obscurely ribbed, densely appressed hispid; pappus of copious fine barbellate setae c. 13 mm. long.
