    Leaves
    Leaves (linear-)lanceolate, 3.5–12 × 0.5–2.8 cm, base obtuse to shortly attenuate, apex acute, apiculate, lower surface with subappressed often anvil-shaped hairs, particularly on principal veins and margin, hairs more scattered or absent above; lateral veins 3–5 pairs; petiole 0–7 mm.
    Inflorescences
    Inflorescence single-flowered, axillary but often crowded towards stem apex; bracts foliaceous, much-reduced upwards, with scattered glandular hairs; bracteoles linear or oblanceolate, 6–21 × 0.5–2.5 mm, hairs as leaves with interspersed spreading glandular hairs; flowers sessile.
    Calyx

    Corolla
    Corolla 25–45 mm long, pale to rich blue-purple with paler throat, rarely white throughout, lateral lobes pubescent externally, hairs mainly glandular; tube cylindrical, 11.5–21.5 mm long, somewhat expanded towards mouth; limb in 4+1 arrangement; abaxial lobe offset by 2.5–7 mm; all lobes 12–23 mm long, abaxial lobe 7.5–12.5 mm wide, lateral pair 6–11.5 mm, adaxial pair 4.5–8.5 mm wide, shortly fused at base for 1–3.5 mm.
    Stamens
    Stamens attached 3–6 mm from corolla base; filaments 16–25 mm long; anthers 2.3–3.7 mm long; lateral staminodes 0.5–1.3 mm long.

    Only immature capsule seen, c.16 mm long, glabrous or with short hairs at apex.
    Seeds
    Only immature seeds seen.
    Distribution
    Also in Tanzania.
    Ecology
    Miombo woodland or more open scrub and grassland, bushland, usually amongst boulders on rocky hillslopes, roadsides; 900–1600 m.
