Choripetalae Eichler (1876), is a descriptive botanical name used in the Eichler and Wettstein systems for a group in the flowering plants. It was one of two groups within the Dicotyledones, the other being the Sympetalae. The latter have fused petals (sympetally) which distinguishes them from the free, unfused petals of the Choripetalae.
