The alternate leaves are usually stalked and have a simple or pinnately divided to compound blade. Mostly there are early falling stipples at the base of the petioles .

The four to six sepals are fused bell-shaped or jug-shaped. There are no petals. There are 4 to 15 fused stamens in one or two circles . In the female there are three to five connected carpels and staminodes . Each carpel has only one ovule. The very short style ends in a very small scar.
