Choripetalae

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.[1]

Ruta graveolens, an example of a choripetalous flower.

Thus if the petals are free from one another in the corolla, the plant is polypetalous or choripetalous; while if the petals are at least partially fused together, it is gamopetalous or sympetalous.
