    Spines
    Axillary spines (2)4-rayed, sessile or stalk to 1 mm long, longest ray 6–16 mm long.
    Leaves
    Leaves coriaceous with conspicuous white cartilaginous marginal rim, elliptic or somewhat obovate, 2.5–5.5 × 1–3.5 cm, base cuneate or attenuate, apex (sub)attenuate into stiff mucro, glabrous or midrib strigose beneath, broad sessile glands clustered towards base beneath; petiole 0–6 mm.
    Inflorescences
    Inflorescence axillary but clustered towards stem apex, forming a ± defined short spike to 5.5 cm long; bracts foliaceous but often reduced and more broadly obovate, typically 10–26 × 6–24 mm, apex often rounded and abruptly narrowed into a prominent mucro; bracteoles whitish except for darker midrib, linear-lanceolate or pairs at spike base oblanceolate, 8–15 × 0.7–1.5(2.5) mm, midrib strigose.
    Calyx
    Calyx green(-brown) with paler margin; outer lobes subequal, ovate or lanceolate, anterior lobe 6–10 × 3–4 mm, posterior lobe 7–11.5 mm long, apex long attenuate into flexible spine, often notched on anterior lobe, venation inconspicuous, external surface glabrous except for occasional sunken glands, rarely strigulose along midrib; lateral lobes 6.5–9 mm long.
    Corolla
    Corolla 34.5–45.5 mm long, yellow or apricot-yellow, glabrous externally; tube 12.5–19 mm long; limb in 4+1 arrangement; abaxial lobe 8–14.5 × 4.5–7 mm, offset by 7–11 mm; lateral lobes 12–19.5 × 7–11 mm, adaxial lobes slightly narrower.
    Stamens
    Stamens with filaments 18.5–19.5 mm long, shortly pubescent in proximal half; anthers (3)3.5–4.2 mm; lateral staminodes 1–2.7 mm, pilose, antherodes 0.6–1 mm.

    Capsule 13.5–17.5 mm long, glabrous.
    Seeds
    Only immature seeds seen, c.5.5 mm wide.
    Distribution
    Also in South Africa (Limpopo).
    Ecology
    On bare or sparsely vegetated sandy soils and stony road verges in Acacia woodland; 850–1500 m.
    Conservation
