Young foliage light-brown to light pink on adaxial and abaxial side, glossy, suborbicular with prominent venation below, margin strongly curved forming deeply-crenate lobes with light-pink outline, succulent and glabrous. Venation basally, 5 – 8 nerves, divided into 2 secondary veins, with reticulate tertiary veins arrangement, all veins prominent above, only primary veins below raised near the petioles becoming sunken towards the margin. Bracts caducous. Inflorescence axillary, erect, dichotomously branched 3 or 4 times; pedicel white; peduncle light brown to green towards the tip, terete, ca. 8 – 11 cm long, glabrous; bracteoles caducous on old branches, present on young ones, ovate, 3 – 5 nerved, margin entire, apex subobtuse, glabrous. Staminate flower: pedicel 9.1 – 9.2 × 0.8 – 0.9 mm, terete, erect to slightly curve at top, glabrous, outer 2 broadly ovate or orbicular-ovate, 8.2 – 9 (– 10) × 8.0 – 8.3 (– 8.8) mm, margin entire, rounded at apex, inner 2 oblanceolate to narrowly obovate, 7.1 – 7.5 (– 8.4) × 2.5 – 4.4 (– 4.5) mm, margin entire, apex rounded to slightly retuse; androecium actinomorphic, 3.0 – 3.6 mm wide, stamens 47 – 53, filaments 0.8 – 1.0 × 0.07 – 0.1 mm, joined at base; anthers yellow, obovoid, 0.8 – 0.9 × 0.6 – 0.8 mm, retuse at apex. Pistillate flower: pedicel white, erect, 7.5 – 7.7 × 0.7 – 1.1 mm; tepals 4, white, glabrous, outer 2, broadly ovate or orbicular-ovate, 10.3 – 11.3 × 9.2 – 9.9 mm, margin entire, apex rounded, inner 2, oblanceolate to narrowly obovate, 8.9 – 9.2 × 2.6 – 2.7 mm, margin entire, apex rounded; ovary pinkish-white, trigonose-obovate, 6.4 – 7.1 × 4.1 – 4.6 mm (excluding wings), glabrous, base and apex somewhat acute; 3 - winged, greenish-white, wings unequal, crescent-shaped with entire margin, 9.4 – 10.6 mm long, abaxial wings much wider, 2.8 – 5.5 mm than lateral wings, 2.8 – 3.9 mm wide; 3 - locules, placentae axile; styles 3, united at base, light green, stigmas 2 - cleft, twisted, papillose and yellow green. Capsules brown, pedicel 15.6 mm long, curved downward; body trigonous-oblong, green, 7.4 – 9.9 × 3.5 – 4.0 mm (wings excluded), slightly curved, base and apex acute, glabrous, wings unequal 8.6 – 9.7 mm long, crescent-shaped, abaxial wing broader, 3.3 – 5.5 mm wide, lateral wings 2.8 – 3.9 mm wide.
