    Flora Zambesiaca Acanthaceae (part 2) by Iain Darbyshire, Kaj Vollesen and Ensermu Kelbessa

    Spiny shrub, erect or straggling, 90–150 cm tall; stems densely hairy with mixed long ascending buff-coloured or greyish hairs and shorter finer retrorse or spreading hairs, upper internodes usually with interspersed spreading glandular hairs.
    Leaves sometimes absent at fruiting, broadly ovate or elliptic, 1.2–3 × 0.8–2.2 cm, base rounded to cuneate, apex acute or obtuse, mucronate, surfaces with numerous ascending pale buff or greyish hairs, most dense on veins beneath; lateral veins 3–4 pairs, prominent beneath; petiole 1–7.5 mm long.
    Inflorescence axillary, numerous in upper portion of branches, each a contracted (1)2–6-flowered unilateral cyme; primary peduncle 2–7(9) mm long; bracteoles stoutly spinose, first pair (10)17–31 × 1–2 mm, often disproportionately longer than others in cyme, soon turning straw-coloured, triangular in cross-section, margin entire, pairs persisting at lower nodes as long paired axillary spines.
    Calyx green or purplish at first with darker venation but soon turning straw-coloured; anterior lobe narrowly oblong, lanceolate or somewhat oblanceolate, 7.5–15 × 2.5–5 mm, base cuneate, margin entire or with minute teeth near apex, apex usually with (1)2–3 mucronate teeth, surface densely silky-hairy with mixed ascending eglandular and spreading glandular hairs, usually obscuring surface; posterior lobe oblong-lanceolate, 8.5–16.5 mm long, apex acute, stiffly mucronate; lateral lobes linear-lanceolate, 7–14.5 mm long.
    Corolla (23)26–31(36) mm long, blue or mauve, with numerous pale retrorse eglandular hairs and few spreading glandular hairs externally; tube 14.5–21 mm long, cylindrical below attachment point of stamens, widening gradually towards mouth; limb in 2+3 arrangement; abaxial and lateral lobes 8.5–14 × 7.5–13.5 mm; adaxial lobes 3.5–6 × 2.5–4.5 mm.
    Stamens attached 7–10 mm from base of corolla tube; filaments 11–21 mm long; anthers 3.5–5.5 mm long; lateral staminodes 1.5–2.5 mm long, minutely glandular towards base, antherodes undeveloped or rarely to 0.8 mm long.
    Ovary with few to numerous pale straight hairs towards apex, extending onto style base; stigma linear, 0.8–1.3 mm long.
    Capsule 12.5–16.5 mm long, with few pale hairs at apex.
    Seeds c.5 × 5 mm.
    Also in South Africa (North West Province, Limpopo).
    Open bushland on dry rocky slopes and outcrops; c.1100 m.
    Conservation notes: Although highly restricted in its range, it is locally common in NE South Africa and was plentiful in the Nylstroom Mts (Obermeijer 1933). Its current status in Zimbabwe is not known, though it is clearly rare having not been recollected since 1929. The main habitats are not threatened.
