Diospyros is a genus of about 450–500 species of deciduous and evergreen trees, shrubs and small bushes. The majority are native to the tropics, with only a few species extending into temperate regions. Depending on their nature, individual species commonly are known as ebony or persimmon trees. Some are valued for their hard, heavy, dark timber, and some for their fruit. Some are useful as ornamentals and many are of local ecological importance.
Taxonomy and etymology 
The generic name Diospyros comes from the ancient Greek words "Dios" (διός) and "pyros" (πυρος). In context this means more or less "divine fruit" or "divine food", though its literal meaning is more like "Wheat of Zeus". The interpretation of Diospyros is however sufficiently confusing to have given rise to some curious and inappropriate interpretations such as "God's pear" and Jove's fire". The name Diospyros was originally applied to the Caucasian Persimmon (D. lotus).
The genus is a large one and the number of species has been estimated variously, depending on the date of the source. The Royal Botanic Gardens, Kew list has over 1000 entries, including synonyms and items of low confidence. Over 700 species are marked as being assigned with high confidence.
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, 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 green fruits are rich in tannins and thus avoided by most herbivores; when ripe they are eagerly eaten by many animals however, such as the rare Aders' Duiker (Cephalophus adersi).

- Charaxes khasianus (Kihansi Charaxes) – recorded on D. natalensis
- Dophla evelina (Redspot Duke) – recorded on D. candolleana
- Actias luna (Luna Moth) – recorded on persimmons
- Callosamia promethea (Promethea Silkmoth) – recorded on persimmons
- Citheronia regalis (Regal Moth) – recorded on American Persimmon (D. virginiana)
- "Cnephasia" jactatana (Black-lyre Leafroller Moth)
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.
