Flowers solitary in the axils of the upper leaves or leaf-like bracts, sometimes running up into distinct racemes or narrow panicles, normally always in opposite pairs. Pedicels (lowermost) 5-20 mm long. Calyx ± distinctly bilabiate, tube (0.6-)1-2 mm long, posticous lobes 3-4.75 x 0.5-0.9 mm, anticous lobes slightly broader, glandular-puberulous together with coarse acute hairs up to c. 0.5-1 mm long. Corolla tube 8-12 x 2.3-3.5 mm in throat, narrowly funnel-shaped, limb almost regular, 9-18 mm across, posticous lobes 3-7 x 2-5 mm, anticous lobe 3.5-8 x 2.2-5 mm, all oblong-elliptic, often white, sometimes pale shades of pink, lilac or mauve, tube orange or yellow, pubescent outside, hairs up to 0.8 mm long, some gland-tipped, usually with 5 longitudinal bands of clavate hairs inside throat, hairs sometimes few.
