Ranunculus arvensis, the field buttercup, belongs to the family Ranunculaceae. The English name is Corn Buttercup. The buttercup is native to Europe and North Africa, as well as the temperate zones of Asia. In Europe it is endangered in its population, since it grows mainly in the field, in grain, and today is suppressed by herbicides and the high population densities. In northern Europe and in the alpine regions, he was always rare. It grows well on clay soils.
