Growth flush-wise, flushes developing from large buds. Buds covered by 2-ranked, brown, caducous budscales with lengthwise veins; new leaves developing in bright white or pink tassels. Stipules present in the buds, very tender, caducous immediately after the unfolding of the bud, leaving hardly any scar.

Leaflets opposite, sessile, oblong to lanceolate, 2.5-6 by 0.6-2 cm; apex obtuse but obliquely emarginate; base rounded or auriculate on the lower side; midrib very excentric, at 1-2.5 mm from the upper margin; usually glabrous, sometimes along the midrib sparsely hairy, nerves invisible on both surfaces (plurijuga Maniltoa TYPE leaf ).

Stamens 30-32; filaments 13-18 mm, free or slightly connate for 0.75 mm at the base; anthers apiculate. Ovary densely hairy, the stipe c. 7 mm; style 5-7 mm;
