Michelia is a genus of flowering plants belonging to the Magnolia family (Magnoliaceae). The genus includes about 50 species of evergreen trees and shrubs, native to tropical and subtropical south and southeast Asia (Indomalaya), including southern China.

The Magnoliaceae are an ancient family; fossil plants identifiably belonging to the Magnoliaceae back to 95 million years. A primitive aspect of the Magnolia family is that their large, cup-shaped flowers lack distinct petals or sepals. The large non-specialized flower parts, resembling petals, are called tepals.

The leaves, flowers, and form of Michelia resemble Magnolia, but the blossoms of Michelia generally form clusters among the leaves, rather than singly at the branch ends like Magnolia.

Several of the larger species are locally important sources of timber. Some species, including the Champak (M. champaca) and M. doltsopa are grown for their flowers, both on the tree and as cut flowers. Champak flowers are also used to produce an essential oil for perfume. A few species have been introduced to gardens or as street trees outside of the Indomalaya region, including M. figo, M. doltsopa, and M. champaca. The genus is named after the Florentine botanist Pietro Antonio Micheli (1679–1737).

[edit] Recent changes in classification

Morphological data[1] and molecular data[2][3] recently showed that the genus Michelia is very closely related to subgenus Yualania of genus Magnolia. Many botanists now treat the genus Michelia accordingly. New combinations of names have been provided for. For further information see under genus Magnolia.
