Flowers bisexual, in terminal umbelliform racemes; the peripheral flowers fertile, the central ones sterile, usually replaced by elongate nectaries with a cavity or pocket in which abundant nectar accumulates; bracteoles appressed to the calyx, similar in form to the sepals. Calyx of 4 decussate sepals; corolla in the form of a calyptra, deciduous; stamens 10 or more numerous, the filaments free; ovary superior, with 4- 1 2 carpels, with numerous ovules.
