Flowers solitary in upper leaf-axils, sometimes running up into short, ± bracteate racemes, sometimes the flowering part continuing as a vegetative twig. Pedicels up to 3-13 mm long. Calyx tube c. 0.1 mm long, lobes c. 4.5-6.5 x 1-1.7 mm, oblong to elliptic, subacute, glandular-pubescent, hairs up to 0.3-0.6 mm long. Corolla tube c. 18-23 x 2.5-3 mm in throat, cylindric, abruptly expanded near apex, mouth laterally compressed, limb slightly bilabiate, c. 15-22 mm across lateral lobes, posticous lobes 5.5-9 x 5.2-7 mm, anticous lobe 6.5-9 x 5.5-7 mm, cuneate to broadly ovate, apex sometimes shallowly retuse, glandular-pubescent outside, hairs up to 0.25-0.6 mm long, glistening glands as well, inside delicate clavate hairs at extreme base of anticous lip descending into well-bearded throat, upper surface of lobes minutely glandular-puberulous, scattered glistening glands as well around mouth, lobes white. Stamens: posticous filaments c. 2-3 mm long, anthers 1-1.8 mm, anticous filaments c. 1 mm long, anthers 0.8-1.2 mm. Stigma 0.5-0.7 mm long. Style 13-20 mm. Ovary c. 2 x 1.2 mm. Capsules 5-8 x 2.8-3.5 mm, glabrous or with a few tiny glandular hairs near apex, glistening glands on placentae. Seeds c. 0.7-1.4 x 0.4-0.7 mm.
