**Biogeography of Magnoliaceae**
– The Magnoliaceae family consists of approximately 219 species.
– Geographical range includes subtropical eastern North America, Mexico, Central America, West Indies, tropical South America, southern and eastern India, Sri Lanka, Indochina, Malesia, China, Japan, and Korea.
– Two-thirds of Magnoliaceae species are found in Asia, with the rest spread across the Americas.
– Extant species are widely distributed in temperate and tropical Asia.

**Modern Systematics Research on Magnoliaceae**
– Dandy’s taxonomic proposal in 1927 included 11 genera, but molecular evidence has since questioned this model.
– Studies by Qiu et al., Azuma et al., and Wang et al. have proposed different phylogenetic trees and clades within the Magnoliaceae family.
– Current research includes identifying monophyletic groups and the impact of DNA sequencing on phylogenetic relationships.

**Economic Significance of Magnoliaceae**
Magnoliaceae are not economically significant, but magnolias are cultivated for ornamental purposes.
– Some timber species are harvested for wood.
– Certain species’ bark and flowers are believed to have medicinal properties.
– Magnolias have a cultural tradition in China for their healing qualities.

**Magnolia Classification and Phylogenetics**
– Studies on molecular divergence, phylogeny, and biogeographic implications within the Magnolia genus.
– Comparative analysis of chloroplast genomes in Magnoliaceae species.
– Research on intergeneric relationships and phylogeny of Magnoliaceae species using plastid and nuclear phylogenomics.

**Magnolia Journals, Publications, and Further Reading**
– Various publications cover topics such as evolutionary divergence of floral scents, chloroplast genomes, and phylogenomic incongruences in Magnolia.
– Additional resources include reports on endangered species, classification details, and books on magnolias and their allies for further reading.

Magnoliaceae (Wikipedia)

The Magnoliaceae (/mæɡˌnliˈsii/) are a flowering plant family, the magnolia family, in the order Magnoliales. It consists of two genera: Magnolia and Liriodendron (tulip trees).

Temporal range: Cenomanian - recent
Magnolia virginiana
Scientific classification Edit this classification
Kingdom: Plantae
Clade: Tracheophytes
Clade: Angiosperms
Clade: Magnoliids
Order: Magnoliales
Family: Magnoliaceae

Unlike most angiosperms, whose flower parts are in whorls (rings), the Magnoliaceae have their stamens and pistils in spirals on a conical receptacle. This arrangement is found in some fossil plants and is believed to be a basal or early condition for angiosperms. The flowers also have parts not distinctly differentiated into sepals and petals, while angiosperms that evolved later tend to have distinctly differentiated sepals and petals. The poorly differentiated perianth parts that occupy both positions are known as tepals.

The family has about 219 species and ranges across subtropical 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.
