Flowers usually bisexual, regular, often showy, solitary or in spikes, racemes or panicles. Calyx 5-lobed, often subtended by an epicalyx; petals 5, large, mostly twisted, stamens numerous, monadelphous, the staminal tube conspicuous, enclosing the gynoecium; anthers one-loculate, with thorny pollen grains. Ovary 5- to many-carpellate, the style-branches as many as or twice as many as carpels, the stigma often capitate to discoid or introrsely decurrent. Fruit commonly capsular or schizocarpous. Embryo curved, endospermous.
