Inflorescences: sessile, brachyblast simple or warted with up to 10 protuberances, up to 20 by 10 mm, in male (5-)10-50-flowered, in female 5-25-flowered; flowers at first with hairs 0.4-1 mm long, glabrescent, perianth 3-lobed, white, pink or red inside. Male flowers: pedicel (15-)20-30 mm long, bracteole 1-3 mm long, subpersistent, about median; buds mitriform, triquetrous in cross section, 6-10 by 9-15 mm, cleft nearly to the base, lobes broad, reniform, 0.5(-l) mm thick; staminal disc flat or ± convex, circular or ± triangular, 3-5 mm in diameter; anthers 14-23, just sessile, oblong, 1-1.5 mm long, horizontal or ± oblique, not touching; androphore 0.5-1 mm.
