Cupania L. is a genus of flowering plants in the family Sapindaceae, order Sapindales, first described by Carl Linnaeus in his Species Plantarum (1753). The genus comprises approximately 58 accepted species — with around 127 names tracked in the GBIF backbone — all native to the tropical Americas.
The genus is distributed from Mexico and the southernmost tip of Florida southward through Central America, the Caribbean islands, and the length of South America to northern Argentina. This broad Neotropical range places Cupania among the characteristic woody genera of tropical lowland and montane forests in the region.
Cupania belongs to the soapberry family (Sapindaceae), which also includes economically important plants such as lychee (Litchi chinensis), longan, and maple (Acer). Members of the family typically bear pinnately compound leaves, small flowers, and fleshy or capsular fruits, and Cupania shares these general traits as a tree or shrub genus of forest understories and edges throughout its range.
Notable species include Cupania guatemalensis, C. latifolia, C. laurifolia, and C. scrobiculata, illustrating the genus's spread across Central and South America.
Etymology
The genus name Cupania was established by Carl Linnaeus in 1753. It is named in honor of Francesco Cupani (1657–1710), an Italian Franciscan friar, botanist, and naturalist who authored Hortus Catholicus (1696), an important early botanical catalogue of Sicilian plants.
Distribution
Cupania is native to the tropical Americas, with a range extending from Mexico and south Florida through Central America, the Caribbean, and South America as far south as northern Argentina. The genus is absent from the Old World.
