Leaves subsessile, lanceolate to linear, obtuse to acute at the apex, cuneate at the base, 2 1/2–1 in. long, 6–2 lin. wide, entire, rarely with 1–2 irregular teeth, finely hirsute above and on the nerves below, at length more or less glabrescent, glaucous from sessile glands below, at least when young; nerves rather prominent below, 4–5 on each side, very oblique, transverse veins distinct. Pedicels 1 1/2–2 (at length over 2) lin. long, ebracteolate; nectaries sessile. Calyx 3–3 1/2 lin. long, pubescent and mealy-glandular; segments subulate-lanceolate, finely acuminate. Corolla rose-coloured, obliquely campanulate, 1–1 1/3 in. long, rufo-pubescent; lowest lobe orbicular, subapiculate, 1/4 in. in diam. Capsule acuminate-rostrate, almost 1 in. long, 2 lin. wide, pubescent, 4-sulcate, obtusely quadrangular. Seeds not quite 1 lin. long, margins acute, faces like the broad sides finely or quite obscurely rugose. —Hiern in Cat. Afr. Pl. Welw. i. 797 (excl. Oliver's syn.).
