description

They are evergreen, perennial, mostly herbaceous plants , less often sub-shrubs , shrubs or small trees. Few species have spines. The simple, often sessile leaves are mostly alternate, rarely opposite and the leaf margins are entire or serrate.

The flowers are individually in the leaf axils or in zymose , racemose or spike-like inflorescences . The hermaphrodite, five-fold flowers are zygomorphic ; as the common names in the different languages indicate, they are fan-shaped. There are almost always five small sepals . The five petals are fused at the base. There is only one circle with five free stamens . Two carpels are a halbunter- or permanent ovary grown.

They form stone fruits . The seeds can be winged or wingless.
