The Ebenaceae are a family of flowering plants belonging to order Ericales. The family includes ebony and persimmon among about 768 [2] species of trees and shrubs. It is distributed across the tropical and warmer temperate regions of the world. [3] It is most diverse in the rainforests of Malesia, India, tropical Africa and tropical America. [4]
Many species are valued for their wood, particularly ebony, for fruit, and as ornamental plants.
The fruits contain tannins, a plant defense against herbivory, so they are often avoided by animals when unripe. The ripe fruits of many species are a food source for diverse animal taxa. The foliage is consumed by insects.
The plants may have a strong scent. Some species have aromatic wood. They are important and conspicuous trees in many of their native ecosystems, such as lowland dry forests of the former Maui Nui in Hawaii, [5] Caspian Hyrcanian mixed forests, Khathiar–Gir dry deciduous forests, Louisiade Archipelago rain forests, Madagascar lowland forests, Narmada Valley dry deciduous forests, New Guinea mangroves, and South Western Ghats montane rain forests.
Ebony is a dense black wood taken from several species in the genus Diospyros , including Diospyros ebenum (Ceylon ebony, Indian ebony), Diospyros crassiflora (West African ebony, Benin ebony), and Diospyros celebica (Makassar ebony). Diospyros tesselaria (Mauritius ebony) was heavily exploited by the Dutch in the 17th century.
The family includes trees and shrubs. The leaves are usually alternately arranged, but some species have opposite or whorled leaves. The inflorescence is usually a cyme of flowers, sometimes a raceme or a panicle, and some plants produce solitary flowers. Most species are dioecious. The flower has 3 to 8 petals, which are joined at the bases. There are usually several single or paired stamens, which are often attached to the inner wall of the corolla. Female flowers have up to 8 stigmas. [3] The calyx is persistent. [6] The fruits are berry-like or capsular. [3] Like the wood of some species, the roots and bark may be black in color. [6]
The family name Ebenaceae is based on the genus name Ebenus, published by Otto Kuntze in 1891. [7] It is a later homonym of Ebenus L., a genus already named in the family Fabaceae, and is thus nomen illegitimum . The plant that Kuntze had named Ebenus was accordingly reassigned to the genus Maba, which in turn has since been included in the genus Diospyros.
Because the name Ebenaceae had become well known, having been used in major botanical references such as Bentham and Hooker's Genera Plantarum , Engler and Prantl's Natürlichen Pflanzenfamilien, and Hutchinson's Families of Flowering Plants, it was conserved [8] and is therefore legitimate. [9]
During the last century, seven genera have been included in the family at one time or another. [3] One phylogenetic analysis reduced the family to four genera: [6]

The Cornaceae are a cosmopolitan family of flowering plants in the order Cornales. The family contains approximately 85 species in two genera, Alangium and Cornus. They are mostly trees and shrubs, which may be deciduous or evergreen, although a few species are perennial herbs. Members of the family usually have opposite or alternate simple leaves, four- or five-parted flowers clustered in inflorescences or pseudanthia, and drupaceous fruits. The family is primarily distributed in northern temperate regions and tropical Asia. In northern temperate areas, Cornaceae are well known from the dogwoods Cornus.
The Fagaceae are a family of flowering plants that includes beeches, chestnuts and oaks, and comprises eight genera with about 927 species. Fagaceae in temperate regions are mostly deciduous, whereas in the tropics, many species occur as evergreen trees and shrubs. They are characterized by alternate simple leaves with pinnate venation, unisexual flowers in the form of catkins, and fruit in the form of cup-like (cupule) nuts. Their leaves are often lobed, and both petioles and stipules are generally present. Their fruits lack endosperm and lie in a scaly or spiny husk that may or may not enclose the entire nut, which may consist of one to seven seeds. In the oaks, genus Quercus, the fruit is a non-valved nut called an acorn. The husk of the acorn in most oaks only forms a cup in which the nut sits. Other members of the family have fully enclosed nuts. Fagaceae is one of the most ecologically important woody plant families in the Northern Hemisphere, as oaks form the backbone of temperate forest in North America, Europe, and Asia, and are one of the most significant sources of wildlife food.
Oleaceae, also known as the olive family or sometimes the lilac family, is a taxonomic family of flowering shrubs, trees, and a few lianas in the order Lamiales. It presently comprises 28 genera, one of which is recently extinct. The extant genera include Cartrema, which was resurrected in 2012. The number of species in the Oleaceae is variously estimated in a wide range around 700. The flowers are often numerous and highly odoriferous. The family has a subcosmopolitan distribution, ranging from the subarctic to the southernmost parts of Africa, Australia, and South America. Notable members include olive, ash, jasmine, and several popular ornamental plants including privet, forsythia, fringetrees, and lilac.
The Elaeagnaceae are a plant family, the oleaster family, of the order Rosales comprising small trees and shrubs, native to temperate regions of the Northern Hemisphere, south into tropical Asia and Australia. The family has about 60 species in three genera.
The Caprifoliaceae or honeysuckle family is a clade of dicotyledonous flowering plants consisting of about 860 species, in 33, to 42 genera, with a nearly cosmopolitan distribution. Centres of diversity are found in eastern North America and eastern Asia, while they are absent in tropical and southern Africa.
Lauraceae, or the laurels, is a plant family that includes the true laurel and its closest relatives. This family comprises about 2850 known species in about 45 genera worldwide. They are dicotyledons, and occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Many are aromatic evergreen trees or shrubs, but some, such as Sassafras, are deciduous, or include both deciduous and evergreen trees and shrubs, especially in tropical and temperate climates. The genus Cassytha is unique in the Lauraceae in that its members are parasitic vines. Most laurels are highly poisonous.
The Buxales are a small order of eudicot flowering plants, recognized by the APG IV system of 2016. The order includes the family Buxaceae; the families Didymelaceae and Haptanthaceae may also be recognized or may be included in the Buxaceae. Many members of the order are evergreen shrubs or trees, although some are herbaceous perennials. They have separate "male" (staminate) and "female" (carpellate) flowers, mostly on the same plant. Some species are of economic importance either for the wood they produce or as ornamental plants.
The Sapindaceae are a family of flowering plants in the order Sapindales known as the soapberry family. It contains 138 genera and 1,858 accepted species. Examples include horse chestnut, maples, ackee and lychee.
Alstroemeriaceae is a family of flowering plants, with 254 known species in four genera, almost entirely native to the Americas, from Central America to southern South America. One species of Luzuriaga occurs in New Zealand, and the genus Drymophila is endemic to south-eastern Australia.
Theaceae, the tea family, is a family of flowering plants comprising shrubs and trees, including the economically important tea plant, and the ornamental camellias. It can be described as having from seven to 40 genera, depending on the source and the method of circumscription used. The family Ternstroemiaceae has been included within Theaceae; however, the APG III system of 2009 places it instead in Pentaphylacaceae. Most but not all species are native to China and East Asia.
Diospyros is a genus of over 700 species of deciduous and evergreen trees and shrubs. The majority are native to the tropics, with only a few species extending into temperate regions. Individual species valued for their hard, heavy, dark timber, are commonly known as ebony trees, while others are valued for their fruit and known as persimmon trees. Some are useful as ornamentals and many are of local ecological importance. Species of this genus are generally dioecious, with separate male and female plants.
Didiereaceae is a family of flowering plants found in continental Africa and Madagascar. It contains 20 species classified in three subfamilies and six genera. Species of the family are succulent plants, growing in sub-arid to arid habitats. Several are known as ornamental plants in specialist succulent collections. The subfamily Didiereoideae is endemic to the southwest of Madagascar, where the species are characteristic elements of the spiny thickets.
Diospyros mespiliformis, the jackalberry, is a large dioecious evergreen tree found mostly in the savannas of Africa. Jackals are fond of the fruit, hence the common names. It is a member of the family Ebenaceae, and is related to the true ebony and edible persimmon.
Asteliaceae is a family of flowering plants, placed in the order Asparagales of the monocots.
Myrsine is a genus of flowering plants in the family Primulaceae. It was formerly placed in the family Myrsinaceae before this was merged into the Primulaceae. It is found nearly worldwide, primarily in tropical and subtropical areas. It contains over 280 species, including several notable radiations, such as the matipo of New Zealand and the kōlea of Hawaiʻi. In the United States, members of this genus are known as colicwood. Some species, especially M. africana, are grown as ornamental shrubs.
Diospyros sandwicensis is a species of flowering tree in the ebony family, Ebenaceae, that is endemic to Hawaii. It belongs to the same genus as both persimmons and ebony. Its common name, lama, also means enlightenment in Hawaiian. Lama is a small to medium-sized tree, with a height of 6–12 m (20–39 ft) and a trunk diameter of 0.3 m (0.98 ft). It can be found in dry, coastal mesic, mixed mesic, and wet forests at elevations of 5–1,220 m (16–4,003 ft) on all major islands. Lama and olopua are dominant species in lowland dry forests on the islands of Maui, Molokaʻi, Kahoʻolawe, and Lānaʻi.
Lissocarpa is a genus of flowering plants, described as a genus in 1876. It is classified as belonging to the family Ebenaceae, the ebony and diospyros family. It includes only a few species of small evergreen trees and shrubs species native to tropical South America.
Diospyros revaughanii is a rare species of tree in the family Ebenaceae (ebony).
Diospyros paniculata, or the panicle-flowered ebony, is a species of tree in the ebony family. Endemic to the Western Ghats area of India and parts of Bangladesh, the species is currently listed as Vulnerable in the IUCN Red List.
