    Inflorescences
    Inflorescence a contracted unilateral cyme 1–2.5 cm long in upper axils, each 2–8-flowered, sometimes only one flower developed at a time; bracteoles spinose, pairs unequal in length, the longer 9–17 × 0.5–1 mm, margin entire or with 1–3 short lateral spines to 1 mm long, numerous sterile bracteoles present at lower nodes as axillary spines, often two pairs per axil.
    Calyx
    Calyx at first mauve, paler towards base and with darker venation, later turning pale-scarious; anterior lobe lanceolate, 8.5–14 × 2.5–4 mm, base shortly attenuate, margin with 2–5 short lateral spines 0.5–1.5(2.5) mm long ending in a short bristle, apex spinose or bifidly so, surface strigulose along veins, often with scattered patent glandular hairs; posterior lobe as anterior but 11.5–20 × 3.5–5 mm, marginal spines 1.5–3(6) mm long, apex attenuate into a long spine; lateral lobes linear-lanceolate, 7–9.5 mm long.
    Corolla
    Corolla (22)25–37 mm long, lilac or blue-mauve, pubescent externally with mixed glandular and eglandular hairs; tube (13.5)15–24 mm long, cylindrical, narrowly campanulate towards mouth; limb in weak 2+3 arrangement or subregular; abaxial lobe (8)10.5–14 × (6)7–10.5 mm; lateral lobes (8)9.5–13 × (5)6–10 mm; adaxial lobes (7.5)9.5–12 × 4–7.5 mm.
    Stamens
    Stamens attached ± midway along corolla tube; filaments (12)19–22 mm long; anthers 2–2.5 mm long; lateral staminodes (1)2–3 mm long, pubescent towards base, antherodes to 0.6 mm long or barely developed.
    Ovary
    Ovary with a ring of minute crisped white hairs at apex; style glabrous; stigma linear, 0.4–0.6 mm long.
    Fruits
    Capsule 9–12.5 mm long, glabrous.

    Mature seeds not seen.
    Distribution
    Not known elsewhere.
    Ecology
    Granite hillslopes and inselbergs, usually amongst large boulders in partial shade or in open woodland; 600–1550 m.
    Conservation
    Conservation notes: Endemic to the central watershed of Zimbabwe, a very local species known from few collections but its favoured habitats are not threatened; probably Least Concern.
