Leaves oblong to oblong-ovate, apex shortly attenuate, mostly blunt, rarely acutish, base broadly cuneate to rounded, thin-coriaceous, glabrous, showing numerous minute pel-lucid points against strong light, (15-)20-30 by 7-11 (-16) cm, in suckers or young shoots up to 36 by 17 cm, entire, midrib strongly obtusely prominent beneath, nerves (8-)10-12 cuved-ascendent pairs faintly looping before the edge, veins obliquely transverse, reticulation rather indistinct; petiole 1.5-2 cm. Panicles composed of short lateral cymes, laxly many-flowered, 1-3 in foliate or already defoliate axils, or from the wood of old branches and/or trunk, 7-20 cm, lower branches up to 9 cm, upper ones 2-4 cm; peduncle 2-5 cm, with a basal swelling, glabrous or sparsely appressedly and coarsely hairy, slender in anthesis, stout (2 mm Ø) in fruiting stage as is the rachis. Pedicels slender and 4-6 mm in anthesis, stoutish and c. 1 cm in fruit. Sepals suborbicular, connate in the lower half, lobes 1-1.5 mm. Petals ovate-oblong, a little fleshy, dull cream or yellow to purplish, 3-4 by 1.5 mm, glabrous outside, ± densely yellowish-villous inside. Stamens 2-3 mm; filaments c. 0.7 mm; connective hairy, exceeding the oblong anther cells (1.5 mm) by c. 0.8 mm. Ovary 2.5 mm. Drupe pendulous, oblongoid to ellipsoid, rarely ovoid-oblongoid, slightly laterally or subquadrangularly compressed, (4-)6-10 by (2-)3-6 cm, exocarp coriaceous, whitish or yellow to purplish when fresh and already fully ripe, becoming purplish to blackish in older stages or when dry, smooth, thin, early dis-soluted; endocarp remaining woody and massive in the inner part (1-2 mm), becoming corky or spongious and irregularly longitudinally grooved and/or lacunose-excavated in the outer part (3-5 mm) when exposed to sea-water.
