Range This species occurs from India to Ethiopia and the Sudan, extending towards the drier areas of Namibia, the Northern Province and Northern Cape in southern Africa. Map 4.
Information Stems usually very slender, yellowish. Flowers 2.5-3.5 mm long, in umbellate cymes on short pedicels, thin in texture, 5- or some­times 4-merous, shining and yellowish when dry. Calyx campanulate-turbinate; triangular or ovate-lanceolate lobes very acute to acuminate, longer than or ± as long as tube, erect to reflexed. Corolla campanulate; lobes narrow and very acute, erect or spreading, usually longer than tube. Stamens shorter than corolla lobes; anthers as long as or shorter than fila­ments. Scales none. Ovary globose; styles slen­der, as long as or longer than ovary, subequal. Capsule globose, irregularly circumscissile near base. Seeds ovoid, ± 1.5 mm long; hilum short. Flowering time December to March.

Corolla campanulate, scarcely longer than the calyx; lobes slightly exceeding the tube, narrowly triangular-ovate, very acute; scales broadly-oblong, fimbriate. Stamens slightly exserted, shorter than the corolla-lobes. Styles 2, shorter than the stigmas. Stigmas slender, included, together with the styles about 1/2 in. long.

Information Stems dark-coloured when dry, shorter than in C. hyalina. Flowers in umbellate clusters subtended by a broadly ovate carinate blunt bract barely 1 1/2 lin. long, shortly pedicellate. Calyx broadly campanulate, 1 lin. or a little over 1 lin. long; lobes broadly ovate, obtuse, 5-partite nearly to the base, closely imbricate. Corolla yellowish-white, broadly campanulate, 1 1/2 lin. long, without any scales but foveolate opposite the lobes, or small blunt scales sometimes present; lobes very broadly ovate, obtuse, as long as the tube. Stamens short, inserted in the sinuses; filaments flattened. Styles subulate, shorter than the ovary; stigma capitate. Capsule probably circumscissile near the base.
