Inflorescences mostly in the axils of the upper leaves, sometimes also from lower defoliate parts; ♂ ferrugineous-tomentose, 3½-6 cm long, rhachis slender; female ones seen only in fruiting state, somewhat stouter, c. 4-5 cm long. Calyx lobes ovate, c. 1.5 mm. Petals 4, ovate-oblong, 2 by 1 mm; scales ovate, c. 0.5 mm. ♂ Flowers: column glabrous, 1.5-2 mm. ♀ Flowers not yet known.
