Ebenaceae
Ebenaceae Gürke comprises approximately 2 genera and 750–800 species, the vast majority belonging to the genus Diospyros. Modern molecular phylogenetic studies support the recognition of Ebenaceae as a distinct lineage within Ericales, closely related to Sapotaceae and Primulaceae. Members are characterized by simple alternate leaves, usually unisexual flowers, a superior ovary, and fleshy berry fruits. The family is renowned for producing ebony wood, one of the world's most valuable hardwoods.
Key characteristics
- Evergreen or deciduous trees and shrubs
- Leaves simple, alternate, entire, and exstipulate
- Plants usually dioecious
- Flowers small, actinomorphic, with persistent calyx

Distribution
Ebenaceae is distributed throughout tropical and subtropical regions of Africa, Asia, Australia, the Pacific Islands, and the Americas, with a few species extending into warm temperate regions. The greatest diversity occurs in Southeast Asia, tropical Africa, and Madagascar. Members inhabit tropical rainforests, monsoon forests, dry deciduous forests, woodlands, and subtropical mountain forests. In Pakistan, Ebenaceae is represented primarily by Diospyros lotus (date plum), which occurs naturally in the Himalayan foothills, Hazara, Murree Hills, Swat, Dir, Chitral. Diospyros kaki (Japanese persimmon) is widely cultivated in the northern mountainous regions, for its edible fruits. Species occur in temperate forests, valleys, orchards, and cultivated landscapes.
