    Leaves
    Leaves (ovate-)elliptic or ± obovate, 6.5–12.5 × 2–5.5 cm, base cuneate or attenuate, apex acute or subattenuate, upper surface with pale long hairs, stellate base often falling early or absent, lower surface pale stellate-pubescent, with buff to golden long-armed dendritic hairs on principal veins and margins; lateral veins 5–7 pairs, these and reticulate tertiary venation prominent beneath; petiole 2–10 mm long.
    Inflorescences
    Inflorescence subglobose, 2.5–4.5 cm in diameter; bracts (ovate-) elliptic, 19.5–34 × 5.5–18 mm, with dense golden-bronze long-armed dendritic hairs on margin and principal veins interspersed with paler stellate hairs; bracteoles ± narrowly (ovate-)elliptic, 21.5–27.5 × 6–10 mm.
    Calyx
    Anterior calyx lobe ovate-elliptic, 19–22 × 7.5–10.5 mm, apex bifid, segments obtusely deltate, 1.5–3 mm long, venation subparallel, inconspicuous, indumentum as bracts but sparse towards base; posterior lobe elliptic, 20–22.5 × 7.5–9.5 mm, apex acute or subattenuate, long-armed stellate hairs restricted to distal third, largely glabrous towards base except for simple hairs on margin; lateral lobes linear-lanceolate, 9.5–11.5 mm long.
    Corolla
    Corolla 55–75 mm long, blue or purple with whitish throat and tube, rarely white (occasional plants in a population), glabrous externally or sparsely pubescent towards apex of lateral lobes; tube 21–25 mm long, cylindrical in proximal half, funnel-shaped above; lobes each 23–36 × 19–30 mm, abaxial lobe offset by 7–12 mm.
    Stamens
    Stamens attached ± midway along corolla tube; filaments (19)26–32 mm long; anthers (4)4.5–5.5 mm long; lateral staminodes 5.5–7 mm long, antherodes to 0.5 mm long.
    Ovary
    Ovary glabrous; style puberulous towards base; stigma 3.2–4 mm long.
    Fruits
    Capsule c.16 mm long, apex attenuate, glabrous.
    Seeds
    Seeds 10–10.5 × c.7 mm.
    Distribution
    Also in SW Tanzania, likely to occur in southeastern D.R. Congo.
    Ecology
    Miombo and chipya woodland including dambo fringes; c.1000 m.
