The '''Magnoliaceae''' is a family in the flowering plant Order [[Magnoliales]]. It consists of two subfamilies:
*'''Magnolioideae''', of which ''[[Magnolia]]'' is the most well-known genus.
*'''Liriodendroidae''', a monogeneric subfamily, containing ''[[Liriodendron]]'' (Tulip trees).

Unlike most [[angiosperm]]s, whose flower parts are in rings, the Magnoliaceae have their stamens and pistils in spirals on a conical receptacle. This arrangement is found in old fossil plants and is believed to be primitive for angiosperms. Their flowers are also not so clearly differentiated into having [[sepal]]s and [[petal]]s like most other flowering plants; the "dual-purpose" parts that occupy both positions are known as '''[[tepal]]s'''.

The family has approximately 225 species in 7 genera, although some classification systems include all of subfamily Magnoioideae in genus ''Magnolia''. The family ranges across eastern [[North America]], [[Mexico]] and [[Central America]], the [[West Indies]], tropical [[South America]], southern and eastern [[India]], [[Sri Lanka]], [[Indochina]], [[Malesia]], [[China]], [[Japan]], and [[Korea]].
