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

Morphology General 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.
Morphology General Spines
Axillary spines absent.
Morphology 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.
Morphology Reproductive morphology 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.
Morphology Reproductive morphology Flowers 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.
Morphology Reproductive morphology Flowers 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.
Morphology Reproductive morphology Flowers Androecium 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.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary glabrous; stigma linear, 0.6–1 mm long.
Morphology Reproductive morphology Fruits
Capsule 12–15.5 mm long, glabrous.
Morphology Reproductive morphology 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.

Kenya, Mozambique, Tanzania
