    Habit
    Shrub or shrublet (45)90–300 cm tall; young stems with dense pale dendritic hairs, often yellow-buff on uppermost internodes, white or cream below; woody stems glabrescent.
    Leaves
    Leaves ovate to broadly so, 5–14 × 3–9 cm, base rounded above a short attenuate portion, apex acute or shortly attenuate, surfaces at first white-felty with dense dendritic hairs, sometimes yellow-buff beneath, hairs ± falling early, mature leaves sometimes glabrescent above, more persistent beneath particularly on veins; lateral veins 4–6 pairs, prominent beneath; petiole 8–23 mm long.
    Inflorescences
    Inflorescence subglobose, 2.7–5.5 cm in diameter, bracts, bracteoles and calyx green at first with purple margin, apex and blotching, turning brown-scarious except sometimes the outer bracts; outermost 2(4) pairs of bracts imbricate, largely enclosing rest of inflorescence, broadly ovate, 24–40(50) × 18–30(38) mm, surface with unevenly distributed white dendritic hairs most dense along midrib and towards base and margin, pinnate-reticulate venation conspicuous; bracts rapidly reducing in size inwards, those towards outside of head 21–37 × 3.5–9 mm, spathulate or obovate, the innermost linear and down to 13 × 1.5 mm; bracteoles linear to oblong-oblanceolate or oblong-lanceolate, 17.5–30(38) × 1.5–5 mm, ascending, margin and midrib with numerous long antrorse bulbous-based hairs, sometimes with a stellate base.
    Calyx
    Anterior calyx lobe oblong-ovate to obovate, 17–27 × 5.5–11 mm, base cuneate, apex bifid with divergent triangular lobes 2.5–8.5 mm long, venation palmate or subparallel, prominent, surface with long bulbous-based antrorse hairs numerous along margin, sometimes with a stellate base; posterior lobe ovate to lanceolate, 15.5–23 × 5.5–9 mm, apex acuminate, hairs along margin as for anterior lobe, external surface elsewhere largely glabrous; lateral lobes linear-lanceolate, 9–11.5 mm long.
    Corolla
    Corolla 45–68 mm long, white, glabrous externally; tube cylindrical, 27–37 mm long, curved, barely widened at mouth; each lobe 14–25 mm long, abaxial lobe widest, 7.5–14.5 mm wide, offset by 3.5–7.5 mm, adaxial lobes narrower, 6.5–12 mm wide.
    Stamens
    Stamens attached ± midway along corolla tube; filaments 28–35 mm long; anthers 4–4.8 mm long; lateral staminodes 3–4 mm long, pubescent towards base, antherodes 0.6–0.9 mm long.
    Ovary
    Ovary glabrous; style puberulous at base; stigma 2.5–3.5 mm long.
    Fruits
    Capsule 12.5–16 mm long, shortly beaked, glabrous.
    Seeds
    Seeds 6.5–8 × 6–7.5 mm.
    Distribution
    Also in South Africa (Limpopo).
    Ecology
    Amongst boulders or on rocky or sandy soil, often in partial shade of dry woodland and riverine thickets; 400–1450 m.
    Conservation
    Conservation notes: Rather local with scattered distribution, common around Matopos in W Zimbabwe (Plowes 1439, 1687 notes "a very common shrub round bases of drier kopjes in the Matopo hills"); Least Concern.
