Morphology General Habit
Shrub 1.5–2 m. tall; young branches glabrous, older branches covered with buff to pale brown, thin shiny bark.
Morphology Leaves
Leaves glabrous; blades drying greenish, narrowly oblong to oblanceolate, 7–14.5 cm. long, 1.8–4.9 cm. wide, apex acuminate, base often unequal, obtuse to acute, ± coriaceous, shiny above, midrib prominent beneath; bacterial nodules linear, situated along the midrib plus few dot-shaped and scattered; petiole 0.7–2 cm. long, glabrous; stipules triangular, 3–8 mm. long, mucronulate, puberulous outside, densely covered with silky hairs inside.
Morphology Reproductive morphology Inflorescences
Corymbs terminal on lateral branches 2.5–11.5 cm. long bearing up to 3 pairs of leaves, lax, 3.6–7 cm. across; primary branches 0.3–1.7 cm. long, glabrous; secondary and often tertiary branches present; pedicels 1–9 mm. long, glabrous; bracts brown, papery, 5–9 mm. long, sparsely hairy outside, with dense silky hairs inside; bracteoles conspicuous.
Morphology Reproductive morphology Flowers Calyx
Calyx glabrous; tube 1.25–1.5 mm. long; limb 1.5–2 mm. long, almost twice as wide as the tube, truncate or with subulate lobes not exceeding 0.75 mm. long.
Morphology Reproductive morphology Flowers Corolla
