Sepals 5, free or partly connate, imbricate. Petals 5, free and equal or connate, unequal, apex 2-lobed or subentire. Stamens 5, alternate with petals, free or connate; anthers 2-loculed, dehiscence longitudinal, thickened on back of connective. Disk lobed, with 5 glands or disk annular, margin undulate, glands opposite to petals, free. Ovary superior or inferior, 2- or 3-locular; ovules 2, inverted in each locule; styles ± connate or free.
