The axillary single flowers arise opposite the leaves and have only a short flower stalk . The five sepals are not overgrown, overlap each other like roof tiles (imbricat) and are egg-shaped to oblong-round. The five petals are also not grown, nailed and bluish to purple. There are ten stamens . The stylus is angular and not obsolete. The ovary is pyramidal, each of the five carpels have two ovules .
The fruit is a pyramid-shaped capsule that opens with flaps ; the seeds form mucus.
