Buttercups are distributed throughout the world and are especially common in woods and fields of the north temperate zone. However, if the development of submergence-acclimated leaves is similar to heterophylly in aquatic and amphibious plants, terrestrial plants may be able to decrease cell wall and cuticle thickness in response to submergence, and even change the composition of the cuticle in order to decrease gas diffusion resistance (cf.
