Its Inflorescences occur in clusters of 1–5 on branches, and are organized on slightly hairy peduncles that are 1.5–4 by 0.3–0.7 millimeters. Each inflorescence has up to 2 flowers. Each flower is on a slightly hairy pedicel that is 11–24 by 0.2–0.8 millimeters. The pedicels are organized on a rachis up to 5 millimeters long that have 2–6 bracts. The pedicels have a medial, slightly hairy bract that is 0.5–1 millimeters long. Its flowers are unisexual. Its flowers have 3 free, triangular sepals, that are 1.5–2 by 1.5–2 millimeters.

Male flowers have up to 40–58 stamens that are 0.7–0.8 by 0.7–0.8 millimeters. Female flowers have 3–6 carpels that are 2.2–2.7 by 0.8–1.3 millimeters. Each carpel has up to 6 ovules arranged in two rows. The fruit occur in clusters of 3 arranged on slightly hairy peduncles that are 3–4 by 1–2 millimeters. The individual fruit are attached by slightly hairy pedicles that are 24–26 by 1.5 millimeters. The fruit are oval to elliptical and 18–21 by 12–14 millimeters. The fruit have a pointed tip 1 millimeter long. The fruit are smooth, and densely hairy.[5]
