Inflorescences terminal (sometimes pseudoaxillary), bisexual or sometimes staminate, racemiform, (3-)10-22 cm long; bisexual inflorescences with 1-15 proximal hermaphriditic cymules, distal cymules male; bracts lanceolate, acute to, acuminate, tomentose, ca 1-3 mm long, each subtending several flowers. Staminate flowers with hispidulous-tomentose pedicels 3-8 mm long; calyx-lobes 5, triangular, stel-late-tomentose, 2.2-2.5 mm long, 1.1-1.5 mm broad; receptacle densely villose; petals obovate, 2.3-2.9 mm long, 1-1.3 mm broad, glabrous except for the minutely ciliate margins; stamens 27-43, the filaments 2.5-3 mm long, glabrous and +-papil-lose, the anthers elliptic, 0.7-1 mm long. Pistillate flowers subsessile, the stout pedicels even in fruit only 1-2 mm long; calyx-segments 5, ? unequal, oblong to linear-lanceolate, valvate, 2.5-3.7 mm long, 0.7-1.6 mm broad, stellate-tomentose on both faces; disc obscure; petals (staminodia?) antheriform, callose, swollen, ca 0.3-0.4 mm long; ovary closely tomentose with tawny stellate hairs, the styles free, bifid, copiously stellate-pubescent, ca 4-4.5 mm long, divided more than l/2 way to the base.
