    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.
    Leaves
    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
    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
    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
    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.

    Seeds dark brown, subconic to irregularly ovoid, ± 0.3 mm. long.
