Branchlets nearly 4-angled, often narrowly winged. Petiole 2--15 mm; leaf blade ± narrowly elliptic, 5--35 X 1--8 cm, base cuneate to decurrent, margin crenate-serrate, serrate, less often dentate, or in some leaves subentire, apex acuminate, lateral veins 8--18 pairs. Inflorescences terminal and often also in or above axils of upper leaves, thyrsoid or less often paniculate, lax to almost spikelike and then interrupted or not, 6--25 X 2--8 cm. Calyx campanulate, 3.5--7 mm, outside glabrous or stellate tomentose and with some minute glandular hairs; lobes triangular, 1--2 mm. Corolla orange, pinkish, purple, or mauve, 0.9--1.6 cm; tube 7--11 X (1.2--)2--3.5 mm, inside pilose above middle; lobes suborbicular, 2--6 X 2--5.5 mm, inside glabrous or with some glandular hairs, outside glabrous or stellate tomentose and with some minute glandular hairs. Stamens inserted above or below middle of corolla tube; anthers ovate. Ovary ovoid to subovoid, 2--6 X 1--3 mm, stellate tomentose or glabrous. Capsules ellipsoid to narrowly ovoid, 6--12 X 2--4 mm, with some glandular hairs. Seeds narrowly elliptic, 2--4 mm, winged all around. Fl. Jun-Oct.

Calyx campanulate, outside glabrous or stellate tomentose and with some minute glandular hairs.
