Female inflorescences: cymes of order 1 or 2, 1-3-flowered; peduncles 1-3 mm; pedicels ca. 3 mm; bracteoles 2, basal; calyx and corolla as in male flowers; staminodes ca. 1/2 as long as petals; ovary ovoid, ca. 1.5 mm in diam., stigma thickly discoid, lobed. Fruit globose-ellipsoidal, ca. 4 mm, ca. 3 mm in diam., longitudinally striate and sulcate when dry; persistent calyx explanate, ca. 3 mm in diam., lobes deltoid; persistent stigma capitate or thickly discoid; pyrenes (4-)6, ellipsoidal, ca. 3 mm, ca. 1 mm in diam., ends pointed, abaxially rugose, longitudinally sulcate, laterally smooth, endocarp woody.
