Small tree up to 5 m. Branchlets terete. Leaves chartaceous, elliptic, sometimes elliptic-oblong, 7-8 by 3-4 1/3 cm; base narrow-cuneate; apex acute to short-acuminate; margins usually dentate-crenate in the upper half; nerves 5-6 pairs, rather fine; petiole 5-7 mm. Cymes axillary or slightly extra-axillary, usually at the base of a new shoot, up to 4.25 cm long, sometimes on a leafy axillary brachyblast. Peduncles up to 2.5 cm. Bracts ovate, short-ciliate. Pedicels 2-3.5 mm. Flowers cream-coloured, 5-merous, some flowers occasionally 4-merous. Calyx lobes unequal, usually the outer two smaller, suborbicular or broadly-obovate, rarely subreniform, slightly erose, sometimes short-ciliate. Petals suborbicular, sometimes broad-obovate, 2-2.5 by 2-2½ mm, sometimes slightly contracted at the base, the margin usually minutely denticulate. Disk ± orbicular, c. 1.5 mm ø. Stamens very short, inserted near the margin of the disk; anthers ± triangular. Pistil c. 2/3 mm emerging from the disk, 5(-4)-angular at the base, narrowed into a short, cylindric style.
