A low, sparingly branched undershrub-6 dm high. Branches erect, fairly rigid, at first pilose, later glabrous and scabrous. Leaves lanceolate to lanceolate-ovate, 8-17 mm long, 3-5 mm wide, tapering to a narrowly obtuse apex, coriaceous, alternate to subopposite, suberect, glabrous and shiny above, dorsally convex, ± while punctulate, sparingly pilose on margins and back when young, glabrescent with age, densely imbricated above. Inflorescence terminal, later appearing lateral by the development of one or more branches in the axils of the involucral leaves: involucral leaves several, not differing markedly from the stem leaves except in being more densely aggregated and sometimes slightly narrower. Flowers sessile, bright rose-bluish, each surrounded by a circle of hairs at the base. Calyx circumscissile 1 mm above its base, just below the apex of the ovary, appressed silky pubescent outside, above the plane of circumcision, glabrous below. Tube slender funnel-shaped, not constricted at the plane of circumcision, glabrous inside. 10-25 mm long. Lobes 4, lilac, ovate, obtuse-acuminate, densely sericeous to almost glabrous inside, 5-9 mm long, 4-5 mm wide. Petals 4, deeply and irregularly cut into 4 or more very slender, membranous segments about 1 mm long, with a row of hairs at the back and oblong callus at the base. Stamens 4 + 4, subsessile, filaments very slender, the lower anthers ± 2 mm long, the upper never more than 1/2 as long and most often minute and abortive. Ovary glabrous except for a few minute erect hairs at the apex. Style filiform, inserted laterally on the ovary. Stigma clavate. Fruit glabrous, enclosed in the persistant base of the calyx. Seed with black crustaceous testa.
