Flowers bisexual; hypanthium papillose, hollow, cup-shaped to shortly cylindric, 5-ribbed or rugose at base, extending above the ovary; sepals 5, usually small, petaloid; petals 5, white, as long as or longer than sepals, enclosing lower part of style; stamens 10, in a ring alternating with 10 minute staminodes, anthers globular, opening by terminal pores; ovary inferior, 1-celled, enclosed by lower part of hypanthium, ovules 2–4; style projecting from flower, hairy below stigma. Fruit small, indehiscent, enclosed in hypanthium and crowned by persistent sepals and petals; seed usually solitary, soft.
