Magnolia
Magnolia is a large genus of about 210 to 340 flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. The natural range of Magnolia species is disjunct, with a main center in east, south and southeast Asia and a secondary center in eastern North America, Central America, the West Indies and some species in South America.
