Information
Perennial (? rarely annual) erect herb, 9–60 cm. tall, with few to many rather slender strict or spreading branches from a woody base; stems glabrous, scabridulous or quite densely pubescent with short spreading hairs. Leaf-blades linear to narrowly elliptic, 1–4 cm. long, 0.5–5 mm. wide, acute and often, particularly in wider leaves, ending in a seta up to 1 mm. long, gradually narrowed at the base, glabrous to quite densely covered with spreading hairs at least above and on margins and midvein beneath; stipule-sheath 1–2 mm. long, divided into 2–6 filiform fimbriae (1–)2–6 mm. long. Inflorescences lax, with 2–several flowers at each node, some with short pedicels others long, those in the lower parts of the inflorescence actually axillary but the leaves reduced to stipules only which form hyaline bracts; peduncles 0.1–3(–6) cm. long, internodes of inflorescence 0.6–3.3 cm. long; pedicels 1–9(–18) mm. long, glabrous. Calyx-tube subglobose, ± 1 mm. long, 1.5 mm. wide, glabrous; lobes narrowly triangular, 1.2–2 mm. long, ending in a short seta, glabrous or somewhat scabridulous on the margins. Corolla white to purplish brown with lobes white, pale rose, red or lilac (sometimes only at the apex outside); tube 3.5–5.5 mm. long, the widened part 1–1.3 mm. long, 0.9–1.2 mm. wide, glabrous outside and throat not bearded within; lobes ovate-elliptic, 0.9–1.9 mm. long, 0.8–1.2 mm. wide, ± acute. Style 2.5–3.5 mm. long; stigma-lobes 1.2–1.4 mm. long. Capsule transversely oblong or subglobose, 1–2 mm. long, 1.5–3 mm. wide, glabrous; fruiting pedicel up to 1.3 cm. long. Seeds dark brown, subconic to irregularly ovoid, ± 0.3 mm. long.

Notes
Specimens with broader leaves ending in setae are to be found scattered throughout the distribution of this species and since intermediates occur I have not considered the variety worth retaining.A plant from Tanzania (Uzaramo District, Dar es Salaam, 8 May 1970, Harris 4155!) is a monstrous form of this species with many of the floral organs leaf-like; there are however a few normal flowers and fruits on some specimens. The Kew sheet showed no normal flowers and was at first thought to be an intergeneric hybrid. The pollen proved to be 95% infertile; there are a few large fat 5-furrowed grains but the rest are deformed, collapsed and tiny.
