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

    Habit
    Perennial herb or subshrub, 40–100 cm tall; stems buff-yellow strigose when young, hair bases somewhat swollen with age, persisting on mature stems.
    Spines
    Axillary spines absent.
    Leaves
    Leaves subsessile, blade elliptic or subpandurate, 7.5–18 × 2.5–7 cm, base abruptly cordate, somewhat amplexicaul when young, attenuate above, apex acuminate, surfaces sparsely strigose at least on margin and veins beneath; lateral veins 4–6 pairs.
    Inflorescences
    Inflorescences often clustered towards stem apex, of contracted 1–8-flowered unilateral cymes, to 4.5 cm long; bracteoles paler than leaves at least towards base, pairs unequal and offset, the larger ovate, 10–17 × 4–11.5 mm, margin entire.
    Calyx
    Anterior calyx lobe broadly ovate, 14–20 × 8–15 mm, base rounded or subcordate, margin entire or obscurely denticulate, apex acute, obtuse or subattenuate, surface paler towards base, strigose particularly on margin and principal veins, hairs on margins sometimes with a swollen base; posterior lobe 16–28.5 × 10–20 mm; lateral lobes lanceolate, 4.5–8 mm long.
    Corolla
    Corolla 32–40.5 mm long, white or rarely mauve (see note), salver-shaped, pubescent externally with spreading eglandular and glandular hairs and occasional strigose hairs; tube narrowly cylindrical, 22–30 mm long, barely expanded towards mouth; limb subregular or in weak 2+3 arrangement, widely spreading; abaxial lobe 8.5–10.5 × 8–11 mm wide; lateral pair as abaxial lobe but 5–7.5 mm wide; adaxial pair 5–6 mm wide.
    Stamens
    Stamens attached in distal half of corolla tube; filaments 11.5–17 mm long, glabrous; anthers 2–2.5 mm long; lateral staminodes 1–2.5 mm long, pubescent towards base, antherodes c.0.75 mm long.
    Ovary
    Ovary glabrous; stigma linear, 0.6–1 mm long.
    Fruits
    Capsule 12–15.5 mm long, glabrous.
    Seeds
    Seeds 4–6 mm long and wide.
    Distribution
    Also in coastal Kenya and Tanzania.
    Ecology
    Coastal forest and bushland on coral rag; c.10 m.
    Conservation
    Conservation notes: Assessed as Endangered under IUCN criterion B in F.T.E.A. Although discovery of the Mozambique population greatly extends its Extent of Occurrence, it still qualifies as Endangered based on Area of Occupancy and as the Kenyan site is threatened by development.
