Pistillate inflorescences ramiflorous, solitary, c. 8.5 cm long, c. 1 mm thick, densely hairy to velutinous, 9-20-flowered; pedicel 3-3.5 mm long, upper part c. 0.5 mm long, geniculate (90¡ã bent), densely hairy; bracts 3 per branchlet, densely hairy outside and inside, margin ciliate. Pistillate flowers 2-3 mm diam.; sepals 6, ovate, 1.8-3 by 0.9-1.4 mm, velutinous outside and inside, persistent; ovary globose, c. 1.3 by 1.3 mm, 3-locular, velutinous; style absent; stigmas small, persistent. Infructescences 6-19(-45) cm long, 1-3 mm thick. Fruits globose, 0-2-seeded, fleshy capsules, 10-20 by 14-22 by 13-20 mm, often loculicidally dehiscent, raised glands sometimes present, velutinous outside, densely hairy to velutinous inside, green to orange; pericarp c. 1 mm thick; column 9-15 mm long, curved to straight, caducous to persistent; pedicel 7.5-13 mm long, upper part 2.5-5 mm long.
