    Habit
    Perennial herb 30–170 cm tall, with one to several annual stems from a short woody rootstock; root-crown pale brown-lanate; roots long, spreading, fleshy.
    Leaves
    Leaves sessile, lanceolate to broadly ovate or obovate, 3–15.5 cm long, 0.8–7 cm wide, cordate, broadly cuneate or cuneate-attenuate at the base, obscurely to coarsely serrate, apex acute, scabridulous above, scabridulous to shortly finely crispate-tomentose beneath.
    Capitulum
    Capitula in terminal or terminal and upper axillary compact to lax scorpioid corymbiform cymes, shortly pedicellate, solitary to densely clustered with ascending crispate hairs; involucre ovoid to obconic-cylindrical, 6–11 mm long, 2.5–10 mm in diameter at flowering time; phyllaries 3–5-seriate, lanceolate, 2–8.5 mm long, outer and median usually recurving at least at the apices, thinly pubescent, darker in centre towards the apex and purplish at the margins in upper part; inner purplish and fimbriate-pectinate on upper margins.
    Florets
    Florets many; corolla 6.5–7.5 mm long, purple or mauve, lobes 1.5–2.5 mm long, with stiff hairs at the apex and often with fine hairs along their length.
    Fruits
    Achenes prismatic (3–)4-angled, 2.2–3 mm long, glabrous or almost so; pappus double, outer persistent, membranous, coroniform, lacerate, 0.4–0.6 mm long, inner of brown caducous flattened barbellate setae 1.5–2 mm long.

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

    Habit
    An erect perennial suffrutescent herb with annual stems, up to c. 1.7 m. tall from a small woody rootstock; rootcrowns pale-brownish tufted-lanate; roots numerous, thong-like.
    Stem
    Stems usually solitary, branching above, leafy, pubescent; indumentum a mixture of large long-stalked flagelliform hairs and hairs with an elongate excentric apical cell on a short stalk.
    Leaves
    Leaves subsessile, the largest shortly petiolate, mostly 5–14 x 2–7 cm., broadly elliptic to narrowly oblong-elliptic or lanceolate, apex acute, base cuneate to somewhat rounded, margins serrate; upper surface ± scabrous, rarely glabrescent, the hairs scattered becoming rigid at the base; the lower surface paler and stiffly puberulous particularly on the nerves; venation laxly reticulate and ± prominent beneath.
    Capitulum
    Capitula numerous, aggregated in many 3–20-capitulate clusters; the capitula-clusters corymbiform or somewhat scorpioidly cymose, on long branches; capitula stalks 0–10(20) mm. long.
    Involucre
    Involucres 6–10 x 4–10 mm., spreading to c. 12 mm. wide, narrowly to broadly obconic-campanulate with ± diverging phyllaries, tapering or rounded at the base, occasionally subglobose or subfusiform with phyllaries appressed imbricate.
    Phyllaries
    Phyllaries numerous in many series, stiffly scarious with subhyaline margins, pilose-pubescent sometimes araneose, glabrescent; the outer from c. 2 mm. long, the inner to c. 8 mm. long, lanceolate to lorate, acute mucronate sometimes tapering pungent to the apex, occasionally ± recurved above.
    Florets
    Florets 40–120 per capitulum.
    Corolla
    Corollas purple, 6–9 mm. long, very narrowly funnel-shaped, lobes ± densely setulose at the apex, sparsely glandular on the limb and tube, otherwise glabrous.
    Fruits
    Achenes 2–2.5 mm. long, narrowly obovoid-subcylindric, truncate to slightly rounded at the apex, 4–5-angular and narrowly ribbed on the angles, the faces between with scattered enlarged brownish cells; pappus 2-seriate, the outer of reduced free to ± united lacerate scales, the inner of a few tawny caducous barbellate setae 0.75–2 mm. long.
