    Habit
    Trailing or decumbent suffrutex, branches to 30 cm long radiating from a woody base and rootstock; stems with numerous long coarse spreading or ascending pale hairs, often interspersed with shorter finer spreading hairs.
    Leaves
    Leaves elliptic or narrowly oblong to somewhat obovate or oblanceolate, 2.8–5 × 1–2 cm, base cuneate or attenuate, apex acute to rounded, surfaces with pale coarse subappressed or ascending hairs, evenly distributed above, most dense on veins beneath; lateral veins (3)4–5 pairs; petiole to 5 mm long.
    Inflorescences
    Inflorescences clustered in uppermost axils, often forming dense heads, each cyme unilateral, contracted, 2 to several flowered; bracteoles lanceolate, 18–33 × 4–7.5 mm, margin entire or minutely toothed, apex spinose, sometimes falcate, triplinerved with prominent midrib, indumentum as leaves beneath but with finer more spreading hairs between veins and often with scattered glandular hairs.
    Calyx
    Calyx green or mauve-tinged at first with darker venation, later turning scarious, accrescent; anterior lobe broadly ovate, 23–31 × 17–21 mm, base cordate or rounded, margin laciniate with teeth to 4 mm long, bristle-tipped, apex usually bifidly spinose, indumentum as bracteoles, glandular hairs most conspicuous along laciniae; posterior lobe as anterior but 25–33 mm long, apex attenuate into a short spine; lateral lobes linear-lanceolate, 10–12 mm long.
    Corolla
    Corolla 43–48 mm long, pale blue or pale purple with white tube, pubescent externally, limb with mainly glandular hairs; tube 27–31 mm long, gradually and narrowly expanded above attachment point of stamens; limb in weak 2+3 arrangement; abaxial lobe 15–16 × 10–12 mm; lateral lobes 14–17.5 × 9–11 mm; adaxial lobes 13–14 × 6–8 mm.
    Stamens
    Stamens attached ± midway along corolla tube; filaments 14–16 mm long; anthers held at corolla mouth, 3–3.5 mm long; lateral staminodes 2–3 mm long, pilose, antherodes 1–1.5 mm long.
    Ovary
    Ovary with few white hairs at apex; style glabrous; stigma subcapitate, 0.5–0.7 mm long.
    Fruits
    Capsule 20–22 mm long, shortly beaked, glabrous.
    Seeds
    Seeds 7.5–8 × 6.5–7 mm.
    Distribution
    Not known elsewhere.
    Ecology
    Open rocky slopes, rough rocky grassland, sandy flats amongst exposed laterite; 1500–2100 m.
    Conservation
    Conservation notes: Endemic to the slopes of Mt Sunzu in NE Zambia and adjacent Saisi Valley flats. Although much suitable habitat remains on the mountain, satellite imagery indicates the adjacent valley is widely farmed; probably Vulnerable under IUCN criterion B.
