Scientific name

The magnolia family (Magnoliaceae) are a family of flowering plants (Magnoliopsida). It comprises two genera with about 227 species.


Magnolias are woody plants: trees or bushes . They are evergreen or deciduous. The alternate and spirally arranged leaves are stalked, large and simple. The leaf blade is simple or lobed. They have large stipules .

The flowers are usually individually terminal or axillary. The stalked flowers are hermaphroditic (rarely unisexual) and often large and magnificent. Unlike most flowering plant whose flower parts are arranged whorled, so the Blütenhüll- that are in the magnolia plants all petals (s. L.), Dust and carpels spirally on the axis core , arranged acyclic and usually in plurality (more than six) . The mostly many free and upper carpels usually contain two, rarely up to 20 ovules . Follicles or legumes are formed as fruits, which are spiraling in cone-shaped seed heads. Since this arrangement is also found in early fossil coversamers, the plants of this family are considered to be evolutionarily old (or primitive). The pollination is usually by beetles.

This family of plants is common in America and East Asia. The majority of the species grows in the temperate and tropical zones of Southeast Asia , from the Himalayas east to Japan and south-east across the Malay archipelago to New Guinea and New Britain . The remaining species are distributed in the temperate south-eastern parts of North America via tropical South America to Brazil .


The classification of the Magnoliaceae family is controversial (see AGP website and literature below). It was suggested that there are two subfamilies. The subfamily Liriodendroidae with the only genus Liriodendron and the subfamily Magnolioideae. According to some authors, the subfamily Magnolioideae contains the only extensive genus Magnolia or, according to Chinese authors in particular (see Flora of China 2008), up to 16 small genera.

The Liriodendraceae used to be an independent family, the two species of which are now assigned to the magnolia family.

In the Magnoliaceae family there are only two genera (illustration based on, for example, Hans P. Nooteboom) with around 297 species:

  • Magnolias ( Magnolia L.): With about 295 species.
  • Tulip trees ( Liriodendron L.): It contains only two species.
