Sapindaceaes

Sapindaceae is a family of flowering plants, commonly known as the soapberry family. This family is distributed primarily in tropical and subtropical regions worldwide, with a few representatives extending into temperate zones. The family includes a diverse array of trees, shrubs, and vines. A defining characteristic of many Sapindaceae species is the presence of saponins, a type of glycoside that produces foam when agitated in water, hence the common name.

Economically important members of Sapindaceae include species that yield edible fruits, such as the lychee (Litchi chinensis) and longan (Dimocarpus longan). Other well-known genera include Acer (maples), though their classification within Sapindaceae is sometimes debated and they are often placed in their own family, Aceraceae, by some botanists. The horse chestnut (Aesculus) genus, formerly placed in Sapindaceae, is now generally considered to be in its own family, Hippocastanaceae. Ornamental trees and shrubs are also common within this family. The leaves of Sapindaceae are typically compound, arranged alternately on the stem, and often have toothed margins. Flowers are usually small and inconspicuous, often with five petals and sepals, and are typically arranged in panicles or racemes. The fruits are varied, ranging from capsules and samaras to berries and drupes.
