Are Campanula and Caesalpinia part of the same family?
Campanula Campanula is one of several genera in the family Campanulaceae with the common name bellflower. It takes both its common and its scientific name from its bell-shaped flowers—"campanula" is Latin for "little bell".
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.
