Leaves elliptic to elliptic-oblong to elliptic-acuminate, shortly rather abruptly acuminate at the apex, cuneate at the base, triplinerved from the base, subcoriaceous, glabrous, entire or slightly undulate, 15-20(-25) by 5-7½(-11) cm; midrib and both side-nerves little raised above, very prominent beneath, basal side-nerves ascending along the margin to the leaf-top, anastomosing with numerous secondary nerves from the midrib (these rather prominent beneath) and other subparallel, intercalar, less distinct nerves, veins little but visibly prominent and laxly reticulate on both sides; petiole rugose, thickened, ♂ Fascicles 2-3(-5)-flowered from pubescent tubercles. Pedicels laxly pilose. Calyx ovoid-oblong, beaked, laxly pilose or nearly glabrous, parallel-nerved from base to top, ± 1 ¼-5 by 0.3-0.5 cm. Petals (sometimes 8) oblong-linear, acuminate, slightly fleshy, glabrous, said to be bright yellow to yellowish-white, purplish when dry, c. 0.4-1.5 by 0.2-0.3 cm; scales pilose towards the apex, 3-4 by 1 mm. Filaments 6-7 mm, pilose; anthers 3-5 by 0.5 mm. Fruit shortly apiculate, greenish or somewhat rusty-pilose, soon glabres-cent, set with numerous small tubercles, red-brown when dry and rough to the touch, (2½-)3½-4½ cm diam.; pericarp 0.6 mm thick. Seeds 6-7(-10), densely packed in a juicy pulp, each with a greenish aril which exudes a milky juice, 1-1.5 by 0.6-0.8 cm; peduncle 3-4.5(-7) by 0.3 cm, thickened at the apex, rugose.
