Occurs in Malawi, Zambia, Zimbabwe, Mozambique, Namibia, Botswana and mainly the Northern Province. Grows in bushveld and grassland, also along roadsides and often on rocky soil. Map 71.
Much-branched shrub up to 2.5 m high. Stems woody, many from base, covered with a light grey bark, sinuous, tips decumbent or climbing. Leaves deciduous, ovate-cordate to orbicular-cordate, 10-80 x 7.5-50.0 mm, entire, often folded along midrib, apex obtuse or subÂacute, deflexed, base mostly widely cordate, sericeous to tomentose on both surfaces, more densely so beneath; petiole pubescent, 4-25 mm long. Inflorescence axillary, 1-5-flowered, sometimes forming a kind of leafy panicle at tips of branches; peduncle 25-90 mm long, hairy; pedicels 8-30 mm long, hairy; bracteoles hairy, 2.5-15.0 mm long, often numerous and forming a kind of involucre at base of cyme and then one bracteole foliaceous and up to 40 x 20 mm. Calyx 6-16 mm long, usually greyish pubescent to tomentose, unequal, elliptic to obovate-spathulate, outer sepals smaller than inner ones, all accrescent in fruit, then glabresÂcent and brown. Corolla funnel-shaped, 40-50 mm long, pale mauve or pinkish with magenta centre, limb spreading horizontally up to ± 60 mm wide; midpetaline areas strigose outside. Capsule with thin leathery pericarp, ellipsoid, apiculate, 8-10 mm long. Seed single, ellipsoid, ± 7 mm long, glabrous, light brown. Flowering time November to May.

Shrub up to 2·5 m. high, many-stemmed from the base and much branched. Stems covered with a light grey bark, slender, sinuous, erect, decumbent or climbing at the tips. Leaves deciduous; leaf lamina ovate-cordate to circular-cordate, sometimes oblong cordate, 1–5·5 × 0·8–4 cm., entire, often folded along the midrib, usually with gradually deflexed, obtuse or subacute, rarely acuminate, often mucronate apex, usually widely and shallowly cordate, sometimes obtuse, truncate or rounded, rarely subacute at the base, more or less sericeous to tomentose on both surfaces, more densely so and more silvery so beneath, sometimes fulvo-sericeous above and on the prominent curving lateral veins beneath, very rarely almost glabrous; petioles rather slender, pubescent like the stem, 4–15 mm. long. Inflorescences 1–5-flowered, axillary, sometimes forming a sort of leaf panicle at the ends of the branches; peduncles slender, sometimes nearly obsolete, usually 2–6 cm. long, hairy like stems, petioles, bracteoles and pedicels; bracteoles elliptic or spathulate to linear oblong, rather small to foliaceous, 2·5 × 6 mm. long, often numerous and forming a sort of involucre at the base of the subumbellate cyme and in this case one of them much larger, occasionally resembling a leaf and up to 3 × 2 cm.; pedicels 6×30 mm. long. Sepals elliptic to obovate or orbicular to obovate-spathulate, 5×12 mm. long, obtuse and mucronate or apiculate, much imbricate, greyish-pubescent to tomentose (at least the outer sepals), sometimes only hairy at the base and conspicuously ciliate, the two inner ones conspicuously larger than the outer ones, all accrescent in fruit, becoming subcoriaceous-chartaceous, glabrescent, brown, up to about 16 mm. long. Corolla funnel-shaped, pale mauve or pinkish with magenta centre, up to 7·5 cm. long, with a horizontally spreading limb up to about 6 cm. in diam.; midpetaline areas thinly strigose with rather long appressed hairs outside. Stamens very unequal. Ovary glabrous. Fruit ellipsoid, apiculate, with thinly leathery pericarp, usually 1-locular, 1-seeded. Seed ellipsoid, pale yellowish brown or light brown, glabrous, very finely areolate.
