Receptacle c. ½ mm high, c. 2 mm wide, puberulous, inside sometimes minutely tomentose. Sepals deltoid to triangular, (¼-)½-1¼ mm. Stamens 5 (4), reduced and mostly permanently inflexed in ♀ flowers; filaments 21l2-31l2 mm, glabrous; connective c. ½(-¾) mm, not conduplicate; anthers linear, V4-V2 by c. ¼ mm, latrorse. Ovary reduced in ♂ flowers, subglobose, 2(-3)-locular, 1-2 mm, puberulous; style 1-2 mm, c. ¼ mm Ø, puberulous; stigma capitate, c. ¼ mm. Ovules inserted on the surface of the septs.
