Type
Type: Malawi, Nyika National Park, 8 km from the gate on Rumphi–Chelinda road, Iwarsson & Ryding 986 (UPS!, holo. DSM!, EA!, K!, MAL!, P!, iso.)
Morphology General Habit
Shrub (0.6–)2–3 m high, laxly branched throughout, with up to 25 shoots from a woody rootstock
Morphology Stem
Stems with internodes usually 5–8 cm long, cork-coloured to pale buff-brown, with lenticels 5–25 × 1–2 mm, with antrorse long and/or short hairs, ± eglandular; branches darker brown towards shoot apex; nodes minutely thicker and with a transverse pattern, upper 15 nodes with short (less than 2 cm long) sterile but leafy shoots
Morphology Leaves
Leaves shortly petiolate; blade narrowly oblanceolate to obovate, 1–3(–5.4) × 0.3–1(–1.8) cm, crenate towards apex, with 3–7(–19) teeth, entire towards base, acute to rounded, base attenuate, margin involute, both surfaces with a mixture of short hairs and sessile glands (or glands present only on lower surface), with 4–8 lateral veins per leaf, the basal ones parallel to the leaf margin; petiole 1–9 mm (usually 2–3 mm) long, dorsiventrally flattened, pubescent, occasionally with sessile glands
Morphology Reproductive morphology Inflorescences
Inflorescence of (1–)2–3(–4) verticils per branch, internodes up to 9 cm long; bracts leaf-like, 20 × 5 mm, hairy like the leaves; bracteoles linear (occasionally broader), 8–16 × 1–2 mm, covered with short hairs and occasionally with sessile glands; verticils hemispherical but flat below, 30–45 mm in diameter, with 10 branches, short (2–3 mm long), with 7–9 buds per branch; pedicels 2–3(–6 in fruit) mm long, densely covered with long antrorse hairs, appearing eglandular
Morphology Reproductive morphology Flowers Calyx
Calyx 12–22 mm long, 10–12-toothed, pale green to brown, densely covered with short hairs and sessile glands or eglandular; mouth occasionally oblique with the lower teeth partially united and bent outwards to form an anterior lip; dorsal tooth narrowly triangular, 2–3 mm long, posterior lip 1–2 mm long, apiculate
Morphology Reproductive morphology Flowers Corolla
Corolla (37–)40–50 mm long, with orange hairs; tube 22–30 mm long, with 3–4 hair fringes within (near base); posterior lip 14–20 mm long, the orange woolly hair enclosing anthers and stigma well developed; anterior lip 3-lobed, deflexed on corolla, central lobe 6–9 mm long, sometimes retuse, lateral lobes shorter and oblique, glabrous to laxly covered with short orange hairs on the outer surface
Morphology Reproductive morphology Fruits
Nutlets 3.8–4.4 × 2–2.2 mm.
Ecology
Upland grassland by outcrops and in secondary bushland on clay soils; 1500–2800 m
Conservation
Vulnerable (VU-D2); habitat in Tanzania under pressure for settlement
Note
With the exception of Iwarsson et al. 1154, from Ifupa, and 1192, from the Kitulo Plateau, the majority of the specimens from Tanzania have obovate leaves with more numerous marginal teeth, and sessile glands on both leaf surfaces, stem and calyx. The material from Malawi and Zambia has more narrowly oblanceolate leaves with fewer marginal teeth and eglandular on the upper leaf surface, stem and calyx.
