Morphology General Habit
Spiny perennial herb or subshrub 5–60 cm tall, from a woody rootstock; stems with upper internodes puberulous on two opposite sides, later glabrescent.
Morphology General Spines
Axillary spines (2)4-rayed, sessile or stalk to 1 mm long, longest ray 6–16 mm long.
Morphology 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.
Morphology Reproductive morphology 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.
Morphology Reproductive morphology Flowers 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.
Morphology Reproductive morphology Flowers 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.
Morphology Reproductive morphology Flowers Androecium 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.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary glabrous; stigma linear, 1.2–1.9 mm long.
Morphology Reproductive morphology Fruits
Capsule 13.5–17.5 mm long, glabrous.
Morphology Reproductive morphology 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
Conservation notes: Known from few localities but bare ground is a significant habitat; Least Concern.
