Biology:Dillenia

From HandWiki

Dillenia is a genus of evergreen or semi-evergreen trees and shrubs in the flowering plant family Dilleniaceae, native to tropical and subtropical regions of southern Asia, Australasia, and the Indian Ocean islands.[1]: 154–156 [2][3]

The genus is named after the German botanist Johann Jacob Dillenius.[4]

Structure

The leaves are simple and spirally arranged. They are generally large, in the case of Dillenia reticulata reaching 1.27 m (4 ft 2 in) in length and about 41 cm (16 in) wide.[5] The flowers are solitary, or in terminal racemes, with five sepals and five petals, numerous stamens (up to 900 in the case of Dillenia ovalifolia[6]), and a cluster of five to 20 carpels. Some species, such as Dillenia indica[7][8] and Dillenia megalantha[9] can have flower diameters of 20 cm (7.9 in). They are superficially similar in appearance to Magnolia flowers.[3]
