Herb with woody tuberous rootstock, erect, tufted; stems wiry, ± unbranched, white-tomentose, glabrescent with age, 13–180 cm tall.
Morphology Leaves
Leaves sessile, ovate to narrowly lanceolate or elliptic, 5–15 cm long, 0.5–4 cm wide, rounded to attenuate into a slightly to prominently expanded marginally ± laciniate-dentate ± sheathing base, margins acutely serrulate, apex acute, thinly arachnoid-tomentose and ± glabrescent becoming green above, more densely and persistently so especially on veins and whitish beneath, with numerous subparallel ascending veins.

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

Morphology General Habit
An erect suffrutex, 20–90 cm. tall, from a woody rootstock.
Morphology Stem
Stems annual, 1-several, simple or sometimes branching near the apex, leafy to near the apex, white sericeous-lanate.
Morphology Leaves
Leaves ± discolorous, membranous, stem-sheathing at the base, mostly 4.5–16 x 1–4 cm., narrowly oblong-lanceolate to narrowly elliptic, ± tapering acute at the apex, cuneate to rounded below narrowing to a winged petiole-like midrib before grading into a cylindric, partially or deeply cleft, membranous sericeous-lanate sheath 5–20 mm. long, or sometimes lamina subsessile and subauriculate; margins finely sharply irregularly serrate, the serrations becoming linear teeth to c. 5 mm. long on the winged midribs and upper margins of the sheath; upper surface green often drying brown and sparsely finely appressed lanate or glabrescent; lower surface white araneose-sericeous; main nerves 10–16 on each side of the midrib, prominent beneath; reticulate tertiary venation inconspicuous.
Morphology Reproductive morphology Inflorescences Capitulum
Capitula solitary, terminal, occasionally 2–4 on long stout stalks.
Morphology Reproductive morphology Inflorescences Bracts Involucre
Involucres mostly 22–30 x 18–28 mm., spreading to c. 45 mm. wide, obconic-campanulate.
Morphology Reproductive morphology Inflorescences Bracts Phyllaries
Phyllaries numerous, appressed imbricate, coriaceous or ± cartilaginous, sparsely finely puberulous to glabrescent, margins very narrowly hyaline; the outer extending briefly onto the capitulum stalk, from c. 4 mm. long and narrowly ovate, increasing to c. 23 mm. long becoming lorate-lanceolate inside; middle phyllaries up to c. 6 mm. wide, obtuse at apex; inner phyllaries narrower.
Morphology Reproductive morphology Flowers Florets
Florets very numerous; corollas bright- or deep-red, up to c. 25 mm. long, with a long slender tube abruptly dilated into a short cylindric, deeply narrowly-lobed limb which exceeds the pappus and involucre, glabrous.
Morphology Reproductive morphology Fruits
Achenes 10–15 mm. long, narrowly cylindric, obscurely narrowly many-ribbed, densely hispid; pappus of copious barbellate setae 10–17 mm. long.
