The inflorescence is racemose, flowers are snow- to ivory-white, borne on the outside of the canopy in pairs. Tepals 4, fused into a single structure with stamens curving back at anthesis to reveal the simple style and ovary. Flowering normally takes place from June to August. Fertile flowers are followed by spherical to ellipsoid nut with a small point at the tip, 15-28 mm long and 13-18 mm wide (measurements for dried specimens).
