Description:	Erect shrub up to ±1.2 m high. Stems covered with short silky hairy when young, glabrous or greyish or yellowish canescent when older. Leaves at tips of young branches, firm to subcoriaceous, entire, lanceolate varying to obovate-orbicular, 30-80 x 10-15 mm, base usually cuneate, tip obtuse to acute, often with a white-hairy mucro, green and glabrescent above, silky beneath, ultimately glabrescent; margin ciliate; petiole much shorter than leaf, silky pubescent. Peduncles 1-flowered, short, silky pubescent as are bracteoles, pedicels and calyx; bracteoles 8-18 mm long; pedicels very short. Sepals subequal, lanceolate, 15-18 mm long, up to 28 mm long in fruit. Corolla salver-shaped, tube 70-100 mm long, narrowly cylindric, greenish white and silky outside, deep magenta and glabrous inside; limb white, 45-60 mm wide, spreading, silky on midpetaline areas outside. Capsule ovoid, 19-23 mm long, hairy to glabrous. Seeds ±10 mm long, densely covered with very long, shiny, brownish hairs. Flowering time November to May.

Leaves at the ends of the young branches; leaf lamina from lanceolate or oblanceolate to elliptic, obovate to obovate-circular (ovate-lanceolate in var. ovato-lanceolata) obtuse to acute often with a white-hairer mucro, usually cuneate at the base, 3–8 x 2–5.5 cm, entire, green, glabrescent above, densely white-silky beneath mainly on the veins, ultimately glabrescent; petiole up to 3 cm long, shortly silky-pubescent. Flowers solitary, peduncle up to 1 cm long, densely silky-pubescent as the pedicels, bracts and calyx; pedicels up to 0.5 cm long; bracteoles linear to linear-lanceolate, acute, up to 1.8 cm long. Sepals subequal, lanceolate, very long acuminate, up to 2.8 cm long in fruit. Corolla very long salver-shaped, white or pink, deep magenta inside, up to 11 cm long, appressed, silky outside; tube narrowly cylindric 7–9 cm long; limb spreading, up to 6 cm in diam. Capsule ovoid, up to 2.3 cm long, thinly hairy to glabrous, coriaceous. Seeds densely covered with very long shiny fulvous-cream hairs. (from JSTOR Global Plants website / Flora Zambesiaca) Stem erect, woody, pale brown, downy upwards; leaves short petioled, ascending, narrowly obovate, 1.5–3 in. long, obtuse, entire, narrowed gradually from above the middle to the base, thick, green and glabrous on both surfaces when mature; flowers shortly peduncled, solitary in the axils of the leaves; calyx 4 lin. long; sepals subequal, lanceolate, acuminate, silvery on the back; corolla 3–4 in. long, 1.25 in. in diam.; tube long, subcylindrical; limb scarcely lobed, silvery outside; stamens in two rows above the middle of the tube; filaments short; capsule globose, rigid, as long as the calyx; seeds covered with brown silky hairs. (from JSTOR Global Plants website / Flora Capensis) Erect shrub up to 1.2 m high. Stems greyish or yellowish, covered with short white, silky hairs when young, hairless when older.
