'''Sapindaceae''', also known as the '''soapberry family''', is a [[family (biology)|family]] of [[flowering plant]]s in the order [[Sapindales]]. There are about 140-150 genera with 1400-2000 species.
Sapindaceae members occur in temperate to tropical regions throughout the world. Many are lactiferous, i.e. they contain milky sap, and many contain mildly [[toxic]] [[saponin]]s ([[alkaloid]]s with [[soap]]-like qualities) in either the foliage and/or the seeds. The largest genera are ''[[Serjania]]'', ''[[Paullinia]]'', ''[[Maple|Acer]]'' and ''[[Allophyllus]]''.
The largely temperate genera formerly separated in the families [[Aceraceae]] (''Acer'', ''[[Dipteronia]]'') and [[Hippocastanaceae]] (''[[Aesculus]]'', ''[[Billia]]'', ''[[Handeliodendron]]'') were included within a more broadly circumscribed Sapindaceae by the [[Angiosperm Phylogeny Group| APG]]. Recent research has confirmed the inclusion of these genera in Sapindaceae.<ref name="singh">{{cite book |last=Singh |first=Gurjaran |title=Plant Systematics: An Integrated Approach |year=2004 |publisher=Science Publishers |location=Enfield, New Hampshire |isbn=1-57808-342-7| pages=pp. 438-440}}</ref><ref name="harrington">{{cite journal |last=Harrington |first=Mark G. |coauthors=Karen J.

==Characteristics==
Plants of this family have a variety of habits, from [[tree]]s to [[herbaceous plant]]s or [[liana]]s. Their leaves usually spirally alternate, sometimes (in ''Acer, Aesculus'', and a few other genera) opposite. They are most often [[leaf shape|pinnately compound]], sometimes palmately, or just palmate (''Acer'', ''Aesculus''), with a [[petiole]] lacking [[stipule]]s, but having a swollen base.<ref name="singh"/>
[[Flower]]s are small and [[unisexual]], or functionally unisexual, though plants may be either [[dioecy|dioecious]] or monoecious. They are usually grouped in [[inflorescence|cyme]]s grouped in [[panicle]]s. They most often have four or five [[petal]]s and [[sepal]]s (petals are absent in ''[[Dodonaea]]''). The [[stamen]]s range from four to ten, usually on a [[nectar disc]] between the petals and stamen,their filaments are often hairy. The most frequent number is eight, in two rings of four. The [[gynoecium]] contains two or three [[carpel]]s, sometimes up to six. There is usually only one [[style]] with a lobed [[stigma]]. Most often [[pollination|pollinated]] by birds or insects,with a few species pollinated by wind.<ref name="singh"/>
The [[fruit]]s are fleshy or dry,. They may be [[nut]]s, [[berries]], [[drupe]]s, [[schizocarp]]s, [[capsule (fruit)|capsule]]s (''[[Bridgesia]]''), or [[samara (fruit)|samara]]s (''Acer''). The embryos are bent or coiled, without [[endosperm]] in the seed, but frequently with an [[aril]].<ref name="singh"/>

Sapindaceae includes many species of economically valuable tropical [[fruit]], including the [[lychee]], the [[longan]], the [[Talisia esculenta|pitomba]], the [[korlan]], the [[rambutan]], the [[mamoncillo]] and the [[ackee]]. Other products include [[Guarana]], [[Soapberry|soapberries]] and [[maple syrup]].
Some species of [[Maple]] and [[Buckeye]] are valued for their wood, while several other genera, such as ''[[Koelreuteria]]'', ''[[Cardiospermum]]'' and ''[[Ungnadia]]'', are popular ornamentals. ''[[Schleichera trijuga]]'' is the source of Indian [[macassar oil]].
