Flowers axillary, solitary or in cymes or lateral panicles, bisexual, hypogynous, bracteate. Sepals 5, free, imbricate, persistent. Petals 5, free or connate at base, imbricate. Stamens many, adnate to the base of petals; anthers versatile dehiscing through apical pores or short slits. Ovary superior, 3 - 5-locular, ovules numerous in axile placentation; styles 3 - 5, free or variously united, sometimes completely so; stigmas simple.
