Are Campanula and Caesalpinia part of the same family?
Caesalpinia Caesalpinia is a genus of flowering plants in the legume family, Fabaceae. Historically, membership within the genus has been highly variable, with different publications including anywhere from 70 to 165 species, depending largely on the inclusion or exclusion of species alternately listed under genera such as "Hoffmannseggia". It contains tropical or subtropical woody plants. The generic name honors the botanist, physician, and philosopher Andrea Cesalpino (1519–1603).
Leucaena Leucaena is a genus of flowering plants in the mimosoid clade of the subfamily Caesalpinioideae of the legume family Fabaceae. It contains about 24 species of trees and shrubs, which are commonly known as leadtrees. They are native to the Americas, ranging from Texas in the United States south to Peru. The generic name is derived from the Greek word λευκός ("leukos"), meaning "white," referring to the flowers.
