A woody herb, suffrutex or shrub, 0.65-3 m high. Branches 4-angled, flowering branches simple or sometimes with branchlets up to 11 cm long, the older branches with persistent spine-like or abbreviated hook-like petiole bases up to 1 cm long. Leaves opposite, subopposite or 3(4)-verticillate, petiolate; lamina up to 12 x 8 cm, ovate or ovate-oblong, abruptly acuminate or cuspidate or attenuate at the apex, truncate rounded or slightly cordate at the base, entire or sometimes few-dentate to irregularly dentate to repand-dentate, ± discolorous, membranous, sparsely and appressed pilose above and on the nerves beneath, densely glandular red-punctate beneath, ciliate, sometimes glabrescent; petiole up to 5.7 cm long, shorter in young leaves, slender, distinctly articulate, sparsely hairy. Cymes clustered in terminal, many-flowered, ± condensed, umbel-like inflorescences, 4-11 cm in diameter, sometimes also axillary at the 2-3 sub-apical nodes; peduncles up to 3 cm long, pubescent with short subappressed hairs. Calyx green, 6-8 mm long, campanulate, glabrous; lobes 4.5-5.5 mm long, longer than the calyx tube, c. 2 mm wide at the base, lanceolate, attenuate into a filiform point. Corolla white or cream, sweet-scented; tube 14-19 mm long, slender, glabrous, with sparse minute sessile glands, similar glands also in the lower part of the lobes; lobes 3.5-4 mm long, suborbicular. Stamens and style exserted for c. 9 mm. Fruit 8-10 mm long and wide, subglobose, deep red or purplish-black.
