Inflorescence about 4-18 cm long. Flowers about 3-4 mm diam., unpleasantly perfumed, subtended by 3 small bracts about 0.5 mm long. Perianth about 1.5-2.5 mm long. Sepals about 1.5 x 0.75 mm. Petals about 2 x 1 mm. Stamens 15, usually in fascicles of three (sometimes two), opposite each petal. Each stamen about 2.5 mm long, anthers very small. Pollen yellow. Ovary densely hairy on the inner surface, the hairs being quite long and almost filling the ovary cavity.


Fruits about 5-6 mm long, resembling a shuttlecock. Petals and sepals persistent.


Cotyledons orbicular, about 5-7 mm diam. At the tenth leaf stage: leaf blade elliptic or ovate, glabrous on the upper surface, margin serrate, teeth produced throughout the margin of the leaf blade; midrib slightly raised on the upper surface. Stipules very small, triangular. Seed germination time 12 days.
