Shrub 1–2 m. tall; young branches glabrous; older branches with greyish bark, occasionally flaking.. Leaves glabrous, mostly restricted to the apices of the branches; blades elliptic to broadly elliptic, 6–9 cm. long, 1.8–4 cm. wide, apex obtuse to acute or sometimes shortly acuminate, base narrowly cuneate or attenuate; bacterial nodules dot-shaped, few to several, scattered; petioles 0.8–1.4 cm. long; stipule-limbs truncate, 4–6 mm. long, membranous, glabrous outside, glabrous or with silky hairs within; arista up to 5 mm. long.. Inflorescence sometimes branched or with several close together, terminal on spurs or short leafless branches which are almost suppressed or up to 1.2(–6) cm. long, subumbellate, ± 20-flowered, 1–1.3 cm. across; primary inflorescence-branches absent or up to 2 mm. long; pedicels 0.75–3.5 mm. long, glabrous; bracts inconspicuous, 3–4 mm. long, pubescent inside.. Calyx glabrous; tube 1 mm. long; limb-tube 1–1.5 mm. long, wider than the tube; lobes shortly triangular, ± 0.75 mm. long, 1–1.25 mm. wide at base.. Corolla-tube 0.8–1.3 cm. long, 1.5–2 mm. wide at top, glabrous outside, not bearded at throat; lobes oblong-elliptic, 4–6 mm. long, 1.75–2.5 mm. wide, obtuse, sometimes slightly apiculate..
