Twigs c. 2 mm ø apically, terete to slightly compressed, becoming smooth, dark brown; stipule scars short, pale, transverse. Buds to 3 by 2 mm, ellipsoid, obtuse. Stipules to 12 by 7 mm, broadly elliptic, obtuse, caducous.

Petals pale yellow. Stamens 15; filaments equal to anthers, lorate, tapering; anthers oblong-lorate; appendages very slender, c. 3 times length of anthers. Ovary ovoid, surmounted by an equally long puberulent cylindrical tapering stylopodium and equally long tapering style. Fruit glabrous. Pedicel to 3 by 3 mm, stout, becoming impressed. Calyx lobes vestigial; 3 longer lobes to 7.5 by 0.8 cm, lorate, obtuse, tapering slightly above the to 20 by 23 mm large prominently saccate thickened base; 2 shorter lobes with only to 12 by 2 mm linear projection above the similar base.
