Papilionaceae 

(also Fabaceae), a family of dicotyledonous plants closely related to the family Leguminosae; the plants are often considered to be a subfamily of the Leguminosae. Of the many cosmopolitan species, trees and arboreal lianas are widespread in tropical regions and throughout the southern hemisphere; species growing in temperate regions primarily include herbs, subshrubs, and shrubs. The flowers are papilionaceous. The fruit is usually a typical bean. Many species of Papilionaceae are commercially valuable.
