Female inflorescence: terminal or axillary, supra-axillary or ramiflorous, a solitary flower, fascicle or condensed raceme, 3-9-flowered. Female flowers: 4.5-6.5 mm diam.; pedicels 3.5-4.5 mm long; sepals 4, 2-whorled, D-shaped; outer pair joined, ca. 1 mm long x 2 mm wide; inner pair free, 1.2-2 mm long x 2-3 mm wide; petals 4, free, 2 mm long x 2-3 mm wide; gynoecium fungiform, unlobed; stigma disklike, entire, 2.5 mm diam.
