Dillenia

Dillenia is a genus of about 100 species of flowering plants in the family Dilleniaceae. These plants are native to tropical and subtropical regions of Southeast Asia, Australia, and the Pacific Islands. Dillenia species are typically trees or shrubs, though some can be climbers. They are characterized by their large, simple leaves, often with prominent venation, and their showy, usually yellow, flowers. The flowers typically have five petals and numerous stamens.

Common names for plants in this genus include elephant ear tree, thanks to the large size and shape of some species' leaves, and golden champa. Some species, such as Dillenia indica, are known for their edible fruits, which are often used in jams, jellies, and chutneys. Other species are cultivated for ornamental purposes due to their attractive flowers and foliage. The wood of some Dillenia species is used in construction and for making tools. The genus is named after the German botanist Johann Gottlieb Dillenia.
