The inflorescence is axillary (leaf scar below the leaf rosette) and 2-flowered. The peduncle is 0.5-1.5 cm long and thick. The bracteoles at the base of flower are cup-shaped. They are fleshy and slightly crenate. The yellow flowers are bisexual and sessile. The sepal is deeply 4-lobed, coriaceous, accrescent and reflexed in fruit. The lobes are ovate, measuring 10-14 mm x 6-8 mm, concave, acute, brown-yellow to reddish and persistent. The receptacle is with a disk. There are 4 free petals which are lance-shaped, measuring 8-11 mm x 1.5-2 mm, membranous, hairless and early caducous. There are at most 12 stamens which are sessile, with anthers 6-7.5 mm long, acute, multi-loculate and open with a large ventral valve. The ovary is 1.5-3.5 mm long, semi-inferior, and 2-celled where the superior part is enclosed by the disk and bluntly conical. The style is 0.5-1 mm long and 2-lobed.
The brown fruit is an ovoid or inversely pear-shaped berry, measures 2-3.5 cm long and rather rough. The hypocotyl is cylindrical to club-shaped, measures up to 40 cm x 1.2 cm, often slightly curved, more or less blunt, smooth and shining. It is green tinged with red.
The leaves are arranged decussate and rosette-like at the end of twigs. The stipules are 4-8 cm long, lance-shaped, conspicuous and caducous. The reddish petiole is 1.5-3 cm long. The blade is entire, elliptical-oblong to sublanceolate, measuring 7-18 cm x 3-8 cm, leathery, green and shiny. The apex is acute to apiculate, with wedge-shaped base, distinct above veins, obscure beneath, hairless with minute and scattered black corky warts on the lower surface. It is visible on the older or dried leaves.
Mainly found in riverine mangroves are arround the country
