Inflorescences mostly axillary. Hypanthium sericeous throughout (sometimes densely). Calyx lobes (4 or) 5, to c. 1 mm long. Petals (4 or) 5, 3–5 mm long, white (to cream), marked by oil glands. Stamens 40–80; filaments c. 2–3 mm long, usually white; anther connective with a terminal gland. Ovary (3–) 4 (–5)-locular. Stigma small, capitate.
