Morphology General Habit
Suffrutex with several decumbent or creeping stems 15–30 cm long from a woody rootstock; stems hispid, hairs (buff-)golden, ascending or spreading.
Morphology Leaves
Leaves subsessile, oblong-elliptic or oblanceolate, 4–9.5 × 1.2–3 cm, base cuneate, apex acute or lower leaves obtuse, with numerous (buff-)golden hispid hairs on margin and midrib only or evenly distributed on both surfaces; lateral veins 4–8 pairs, these and reticulate tertiary veins prominent.
Morphology Reproductive morphology Inflorescences
Inflorescence terminal, sometimes also in uppermost leafy axils, densely spiciform or subcapitate, 2–5.5 cm long, each axil single-flowered or lowermost axils 2–3-flowered; bracts oblanceolate or narrowly elliptic, sometimes flushed purple distally or throughout, 9.5–15.5 × 1.5–4.5 mm (basal pairs to 23 × 7.5 mm), base cuneate, apex acute, ± densely glandular-pilose, with subappressed stiff hairs at least on margin and midrib, those on margin sometimes with swollen base; bracteoles as bracts but (elliptic-)oblanceolate to linear, 9–14.5 × 1–2 mm, glandular hairs more numerous; flowers sessile.
Morphology Reproductive morphology Flowers Calyx
Calyx often flushed purple at least towards apex, pale at base; anterior lobe narrowly oblong or subulate, 10–15.5 × 1.5–2.5 mm, apex bifid for 2.5–8 mm, indumentum as bracteoles, two parallel principal veins prominent; posterior lobe narrowly lanceolate or subulate, 10–16.5 × 2–2.7 mm, apex acute, midrib prominent; lateral lobes linear, 9–13.5 mm long.
Morphology Reproductive morphology Flowers Corolla
Corolla 17–22 mm long, white, pink, lilac or bright blue, with or without purple guidelines, lateral lobes sparsely pubescent externally; tube cylindrical, 9.5–11.5 mm long; limb in 2+3 arrangement, abaxial lobe 6–10.5 × 4.5–7 mm; lateral lobes 7–10.5 × 3–6 mm; adaxial pair fused for 0.7–5 mm, free portions oblanceolate to subulate, 4.5–10 × 1.5–4 mm.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens attached c.3 mm from corolla base; filaments 9.5–15.5 mm long; anthers 2.5–3 mm; lateral staminodes 0.25–0.8 mm.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary densely pubescent at least distally, sometimes short glandular hairs at apex; style with few hairs towards base; stigma 1.2–1.9 mm long.
Morphology Reproductive morphology Fruits
Capsule c.14.5 mm long, puberulous.
Morphology Reproductive morphology Seeds
Only immature seeds seen.
Distribution
Also in southern D.R. Congo.
Ecology
Miombo woodland and open wooded grassland; 1100–1500 m.
Conservation
Conservation notes: Rather scarce and known from only seven collections; certainly rare in the Mbala region of Zambia with only a single specimen seen; probably threatened.
