Diospyros is a genus of about 450–500 species of deciduous and evergreen trees. The majority are native to the tropics, with only a few species extending into temperate regions. They are commonly known as ebony or persimmon trees. The generic name is derived from the Greek words διός (dios), meaning "of Zeus" and πυρός (pyros), meaning "grain"[1] and was originally applied to the Caucasian Persimmon (D. lotus).


Diospyros species are important and conspicuous trees in many of their native ecosystems, such as lowland dry forests of the former Maui Nui in Hawaii,[2] Caspian Hyrcanian mixed forests, Kathiarbar-Gir dry deciduous forests, Louisiade Archipelago rain forests, Madagascar lowland forests, Narmada Valley dry deciduous forests, New Guinea mangroves or South Western Ghats montane rain forests. The fruit are rich in tannins and thus avoided by most herbivores when unripe; when ripe they are eagerly eaten by many animals however, such as the rare Aders' Duiker (Cephalophus adersi).

The foliage is used as food by the larvae of numerous Lepidoptera species:








An economically significant plant pathogen infecting many Diospyros species – D. hispida, Kaki Persimmon (D. kaki), Date-plum (D. lotus), Texas Persimmon (D. texana), Coromandel Ebony (D. melanoxylon) and probably others – is the sac fungus Pseudocercospora kaki, which causes a leaf spot disease.

Use by humans

The genus includes several plants of commercial importance, either for their edible fruit (persimmons) or for their timber (ebony). The latter are divided into two groups in trade: the pure black ebony (notably from D. ebenum, but also several other species), and the striped ebony or Calamander wood (from D. celebica, D. mun and others). Most species in the genus produce little to none of this black ebony-type wood; their hard timber (e.g. of American Persimmon, D. virginiana) may still be used on a more limited basis.

Leaves of the Coromandel Ebony (D. melanoxylon) are used to roll South Asian beedi cigarettes. Several species are used in herbalism, and D. leucomelas yields the versatile medical compound betulinic acid. Though bees do not play a key role as pollinators, in plantations Diospyros may be of some use as honey plant. D. mollis, locally known as mặc nưa, is used in Vietnam to dye the famous black lãnh Mỹ A silk of Tân Châu district.

These trees are well-known in their native range, and consequently much used as floral emblems. In Indonesia, D. celebica (Makassar Ebony, known locally as eboni) is the provincial tree of Central Sulawesi, while ajan kelicung (D. macrophylla) is that of West Nusa Tenggara. The emblem of the Japanese island of Ishigaki is the Yaeyama kokutan (D. ferrea). In Thailand, the Gold Apple (D. decandra) is the provincial tree of Chanthaburi and Nakhon Pathom Provinces, while Black-and-white Ebony (D. malabarica) is that of Ang Thong Province. The name of the Thai district Amphoe Tha Tako literally means "District of the Diospyros pier" after a famous local gathering spot.
