Michelia
Michelia is a historical genus of flowering plants belonging to the family Magnoliaceae. The genus included about 50 species of evergreen trees and shrubs, native to tropical and subtropical south and southeast Asia (Indomalaya), including southern China. Today it is regarded as a synonym and section of the genus Magnolia.[1]
Description[edit]
The Magnoliaceae are an ancient family; fossil plants identifiably belonging to the Magnoliaceae date back 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 as Magnolia does.
Uses[edit]
Several of the larger species are locally important sources of timber. Some species, including the champak (Michelia champaca) and Michelia 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 Michelia figo, M. doltsopa, and M. champaca. The genus is named after the Florentine botanist Pietro Antonio Micheli (1679–1737). They grow to the height of 10–45 metres
Recent changes in classification[edit]
Morphological data[2] and molecular data[3][4] recently showed that the genus Michelia is very closely related to subgenus Yulania 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.
