Male inflorescences: cymes of order 1 or 2, 1-3-flowered; peduncles ca. 1 mm; pedicels 2-3 mm, glabrous; bracteoles 2, subbasal; calyx patelliform, ca. 2.5 mm in diam., deeply 4-lobed, lobes deltoid-ovate, apex obtuse; petals 4, oblong-ovate, ca. 2.5 × 2 mm, basally slightly connate; stamens slightly shorter than petals, anthers oblong, ca. 1 mm; rudimentary ovary subglobose, ca. 1 mm, apex obtuse, slightly 4-lobed. Female inflorescences: 1-flowered cymes; pedicels 6-8 mm; bracteoles 2, subbasal, broadly deltoid; calyx and corolla as in male flowers; staminodes ca. 1/2 as long as petals, sterile anthers sagittate; ovary ovoid, ca. 2 mm, ca. 1.5 mm in diam., apex truncate, stigma discoid, 4-lobed. Fruit globose, ca. 6 mm in diam.; persistent calyx explanate, ca. 4 mm in diam.; persistent stigma thinly discoid, 4-lobed; pyrenes 4, ellipsoidal, ca. 5 mm, ca. 2 mm in diam., abaxially and laterally palmately striate and deeply sulcate, pilose, endocarp leathery.
