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

Morphology General Habit
Spreading spiny (sub)shrub 40–100 cm tall, often drying dark brown; stems viscid glandular-pubescent to pilose, with or without interspersed long spreading pale-buff hairs numerous at nodes.
Morphology Leaves
Leaves elliptic to obovate, 1.5–3.7 × 0.5–1.8 cm, base cuneate or attenuate, apex acute to rounded, mucronate, surfaces glandular-pubescent, with long pale-buff or greyish coarse spreading or ascending hairs; lateral veins 3–4 pairs; petiole 0–5 mm long.
Morphology Reproductive morphology Inflorescences
Inflorescence axillary, single-flowered, densely viscid glandular-pubescent to pilose throughout; peduncle 1–11 mm long; bracteoles spinose, 15–33 × 1–2.5 mm, margin entire, sometimes with a narrow blade either side of prominent midrib; pedicels 1–5 mm long.
Morphology Reproductive morphology Flowers Calyx
Calyx green-brown at first with darker reticulate venation, later turning scarious; anterior lobe oblong-elliptic to obovate, 17–24 × 4–7 mm, margin entire or with minute teeth formed by swollen hair bases towards apex, apex attenuate into apical spine, rarely bifidly so, surfaces densely glandular-pubescent, hairs often longest and most dense at base, sparsely strigose along veins and margin; posterior lobe as anterior or sometimes lanceolate, 20–26 × 4–9 mm; lateral lobes linear(-oblanceolate), 16–23 mm long.
Morphology Reproductive morphology Flowers Corolla
Corolla 51–85 mm long, white, fading to pale blue, drying dark blue to blue-black, externally pilose with eglandular and glandular hairs; tube cylindrical, 35–65 mm long, somewhat widened towards mouth; limb in 2+3 arrangement; abaxial and lateral lobes 15–21 × 8–13 mm; adaxial lobes 15–18 × 6–10 mm.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens attached 20–40 mm from base of corolla tube; filaments 27–36 mm long; anthers exserted, 5–7.5 mm long; lateral staminodes 3.5–7 mm long, sparsely to densely hairy at base, antherodes undeveloped or obsolete.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary with dense tuft of white crisped-spreading hairs at apex; style glabrous; stigma clavate or linear, 0.8–2.3 mm long.
Morphology Reproductive morphology Fruits
Capsule 20–25 mm long, glabrous except apical tuft of hairs.
Morphology Reproductive morphology Seeds
Only immature seeds seen.
Distribution
Not known elsewhere.
Ecology
Open bushland, grassland or Brachystegia woodland on dry hillslopes over serpentine rocks; 900–1400 m.
Conservation
Conservation notes: Endemic to a northern section of the Great Dyke of Zimbabwe. Golding (Sthn. Afr. Pl. Red Data Lists: 171, 2002) assessed it as of Least Concern, citing its favoured habitat of open rocky slopes. Mining may have resulted in the loss of some populations, although spoil resulting from small-scale mining can create favourable conditions. In view of the inferred threat, probably best considered Vulnerable under IUCN criterion B.
