Description: Low growing perennial herb or subshrub, often forming compact, prostrate cushions, sometimes erect and tufted. Leaves linear-oblong to narrowly oblanceolate with glandular hairs, particularly on the upper surface. Flowers deep blue to violet, darker near the centre. (from Flora of Zimbabwe website)

Plant usually prostrate, branched or rarely densely tufted under-shrub; branches 2–15(40) cm long, densely leafy. Leaves 1.5–10 x 0.1–0.65(0.9) cm, linear to linear-oblong or narrowly oblanceolate, apex obtuse, short apiculate, attenuate to subsessile or sessile base, sparsely long glandular-hirsute above, very sparsely hispid on major nerve beneath, ciliate especially below; midrib thickened, prominent beneath, at least lower part persistent, spinescent. Flowers sessile to subsessile; bracts to 7 mm long, 1 mm. wide, narrowly linear. Calyx c. 8 mm long, lobes 5–7 mm long, narrowly linear-lanceolate, acute, prominently 1-nerved, long pilose-ciliate. Corolla up to 2.5 cm long, bright deep blue to violet, darker at throat, sparsely and usually shortly glandular-pilose without, lobes subequal, broadly obovate. Lower stamens more than half as long as corolla tube; anthers pilose; style hairy below, slender, exceeding corolla tube. Ovary compressed-ovoid, glabrous. Capsule c. 5 x 4.5 mm laterally compressed-obovoid, pubescent; seeds black. (from JSTOR Global Plants website / Flora Zambesiaca)
