  Stems thin to medium, pale yellowish to reddish. Inflorescences (4-)5-13 (-15) mm diam., usually many-flowered, dense. Flowers 2-5-3-5(-4) mm, sessile or subsessile, white, smooth, 5-merous. Calyx about as long as to longer than corolla tube, campanulate, partly membranous, lobes usually as long as tube (sometimes shorter or longer), triangular to ovate or almost obovate, fleshy or even turgid towards ± acute-pointed apex, often golden-yellow or brownish, shining and finely netted with prominent veins when dry. Corolla lobes shorter than to almost as long as tube, narrowly triangular-ovate to ovate-suborbicular, membranous or somewhat thickened towards shortly apiculate apex, subacute to obtuse, patent in fruit. Anthers scarcely exceeding tube, shorter than to ± as long as narrow filaments. Scales reaching stamens, oblong or spathulate to oblong-ovate or obovate, bifid or simple, shallowly fimbriate at apex. Styles ± as long as
or slightly shorter than the thin stigmas, together as long as or generally longer than ovary. Capsule 1.5-2-5 mm, irregularly ovoid or obovoid to depressed-globose. Seeds 1-1.3 mm, (3-)4 per capsule, ovoid, finely scabrous. Fl. (5-)6-8{-10).
