The Anacardiaceae, commonly known as the cashew family [1] or sumac family, are a family of flowering plants, including about 83 genera with about 860 known species. [2] Members of the Anacardiaceae bear fruits that are drupes and in some cases produce urushiol, an irritant. The Anacardiaceae include numerous genera, several of which are economically important, notably cashew (in the type genus Anacardium ), mango, Chinese lacquer tree, yellow mombin, Peruvian pepper, poison ivy, poison oak, sumac, smoke tree, marula and cuachalalate. The genus Pistacia (which includes the pistachio and mastic tree) is now included, but was previously placed in its own family, the Pistaciaceae. [3]
The cashew family is more abundant in warm or tropical regions with only a few species living in the temperate zones. [4] Mostly native to tropical Americas, Africa and India. Pistacia and some species of Rhus can be found in southern Europe, Rhus species can be found in much of North America and Schinus inhabits South America exclusively. [5]
Trees or shrubs, each has inconspicuous flowers and resinous or milky sap that may be highly poisonous, as in black poisonwood and sometimes foul-smelling. [5] Resin canals located in the inner fibrous bark of the fibrovascular system found in the plant's stems, roots, and leaves are characteristic of all members of this family; resin canals located in the pith are characteristic of many of the cashew family species and several species have them located in the primary cortex or the regular bark. Tannin sacs are also widespread among the family. [6]
The wood of the Anacardiaceae has the frequent occurrence of simple small holes in the vessels, occasionally in some species side by side with scalariform holes (in Campnosperma , Micronychia , and Heeria argentea (Anaphrenium argenteum). The simple pits are located along the vessel wall and in contact with the parenchyma. [6]
Leaves are deciduous or evergreen, usually alternate (rarely opposite), [4] estipulate (without stipule) and imparipinnate (rarely paripinnate or bipinnate), usually with opposite leaflets (rarely alternate), while others are trifoliolate or simple or unifoliolate (very rarely simple leaves are palmate). Leaf architecture is very diverse. Primary venation is pinnate (rarely palmate). Secondary venation is eucamptodromous, brochidodromous, craspedodromous or cladodromous (rarely reticulodromous) Cladodromous venation, if present is considered diagnostic for Anacardiaceae. [5] [7]
Flowers grow at the end of a branch or stem or at an angle from where the leaf joins the stem and have bracts. [5] Often with this family, bisexual and male flowers occur on some plants, and bisexual and female flowers are on others, or flowers have both stamens and pistils (perfect). A calyx with three to seven cleft sepals and the same number of petals, occasionally no petals, overlap each other in the bud. Stamens are twice as many or equal to the number of petals, inserted at the base of the [4] fleshy ring or cup-shaped disk, and inserted below the pistil(s). [5] Stamen stalks are separate, and anthers are able to move. [4] Flowers have the ovary free, but the petals and stamen are borne on the calyx. [5] In the stamenate flowers, ovaries are single-celled. In the pistillate flowers, ovaries are single or sometimes quadri- or quinticelled. One to three styles and one ovule occur in each cavity. [4]
Fruits rarely open at maturity [5] and are most often drupes. [4]
Seed coats are very thin or are crust-like. Little or no endosperm is present. Cotyledons are fleshy. [4] Seeds are solitary with no albumen around the embryo. [5]
In 1759, Bernard de Jussieu arranged the plants in the royal garden of the Trianon at Versailles, according to his own scheme. That classification included a description of an order called the Terebintaceæ, which contained a suborder that included Cassuvium ( Anacardium ), Anacardium ( Semecarpus ), Mangifera , Connarus , Rhus , and Rourea . In 1789, Antoine Laurent de Jussieu, nephew of Bernard de Jussieu, published that classification scheme. [8]
Robert Brown described a subset of the Terebintaceae called Cassuvlæ or Anacardeæ in 1818, using the herbarium that was collected by Christen Smith during a fated expedition headed by James Hingston Tuckey to explore the River Congo. The name and genera were based on the order with the same name that had been described by de Jussieu in 1759. The herbarium from that expedition contained only one genus from the family, Rhus. [9]
Augustin Pyramus de Candolle in 1824, used Robert Brown's name Cassuvlæ or Anacardeæ, wrote another description of the group, and filled it with the genera Anacardium , Semecarpus , Holigarna , Mangifera , Buchanania , Pistacia , Astronium , Comocladia , and Picramnia . [10]
John Lindley described the "essential character" of the Anacardiaceæ, the "Cashew Tribe" in 1831, adopting the order that was described by de Jussieu, but abandoning the name Terebintaceæ. He includes the genera that were found in de Candolle's Anacardieæ and Sumachineæ: Anacardium, Holigarna, Mangifera, Rhus, and Mauria . [5]
The genus Pistacia has sometimes been separated into its own family, the Pistaciaceae, based on the reduced flower structure, differences in pollen, and the feathery style of the flowers. [3] The nature of its ovary, though, does suggest it belongs in the Anacardiaceae, a position supported by morphological and molecular studies, and recent classifications have included Pistacia in the Anacardiaceae. [3] [11] [12] The genus Abrahamia was separated from Protorhus in 2004.(Pell 2004)
The family has been treated as a series of five tribes by Engler, and later into subfamilies by Takhtajan, as Anacardioideae (including tribes Anacardieae, Dobineae, Rhoideae, and Semecarpeae) and Spondiadoideae (including tribe Spondiadeae). Pell's (2008) molecular analysis reinstated the two subfamilies without further division into tribes (Pell 2004). Later, Min and Barfod, in the Flora of China (2008) reinstated the five tribes (four in Anacardioideae), and the single tribe Spondiadeae as Spondiadoideae.
79 genera are accepted: [13]
Members of this family produce cashew and pistachio nuts, and mango and marula fruits. [5]
Some members[ which? ] produce a viscous or adhesive fluid which turns black and is used as a varnish or for tanning and even as a mordant for red dyes. [5] The sap of Toxicodendron vernicifluum is used to make lacquer for lacquerware and similar products.
The name Anacardium, originally from the Greek, refers to the nut, core or heart of the fruit, which is outwardly located: ana means "upward" and -cardium means "heart").
Mangifera is a genus of flowering plants in the cashew family, Anacardiaceae. It contains 64 species, with the best-known being the common mango. The center of diversity of the genus is in the Malesian ecoregion of Southeast Asia, particularly in Sumatra, Borneo, and the Malay Peninsula. They are generally canopy trees in lowland rainforests, reaching a height of 30–40 m (98–131 ft).
Cashew is the common name of a tropical evergreen tree Anacardium occidentale, in the family Anacardiaceae. It is native to South America and is the source of the cashew nut and the cashew apple, an accessory fruit. The tree can grow as tall as 14 metres, but the dwarf cultivars, growing up to 6 m (20 ft), prove more profitable, with earlier maturity and greater yields. The cashew nut is edible and is eaten on its own as a snack, used in recipes, or processed into cashew cheese or cashew butter. The nut is often simply called a 'cashew'.
Anacardium, the cashews, are a genus of flowering plants in the family Anacardiaceae, native to tropical regions of the Americas. The best known species is Anacardium occidentale, which is commercially cultivated for its cashew nuts and cashew apples.
Toxicodendron is a genus of flowering plants in the sumac family, Anacardiaceae. It contains trees, shrubs and woody vines, including poison ivy, poison oak, and the lacquer tree. All members of the genus produce the skin-irritating oil urushiol, which can cause a severe allergic reaction. The generic name is derived from the Greek words τοξικός (toxikos), meaning "poison," and δένδρον (dendron), meaning "tree". The best-known members of the genus in North America are eastern poison ivy (T. radicans) and western poison oak (T. diversilobum), both ubiquitous throughout much of their respective region.
Toxicodendron radicans, commonly known as eastern poison ivy or poison ivy, is a species of allergenic flowering plant. It has numerous subtaxons and forms both vines and shrubs. Despite its common name, it is not a true ivy, but rather a member of the cashew and pistachio family Anacardiaceae. It is different from western poison ivy, Toxicodendron rydbergii, and resembles a number of species.
Sumac or sumach is any of about 35 species of flowering plants in the genus Rhus and related genera in the cashew family (Anacardiaceae). Sumacs grow in subtropical and temperate regions throughout every continent except Antarctica and South America. Sumac is used as a spice, as a dye, and in medicine.
The Annonaceae are a family of flowering plants consisting of trees, shrubs, or rarely lianas commonly known as the custard apple family or soursop family. With 108 accepted genera and about 2400 known species, it is the largest family in the Magnoliales. Several genera produce edible fruit, most notably Annona, Anonidium, Asimina, Rollinia, and Uvaria. Its type genus is Annona. The family is concentrated in the tropics, with few species found in temperate regions. About 900 species are Neotropical, 450 are Afrotropical, and the remaining are Indomalayan.
Pistacia chinensis, the Chinese pistache, is a small to medium-sized tree in the genus Pistacia in the cashew family Anacardiaceae, native to central and western China. This species is planted as a street tree in temperate areas worldwide due to its attractive fruit and autumn foliage.
Semecarpus is a genus of plants in the family Anacardiaceae. It includes 87 species native to the Indian subcontinent, Indochina, Malesia, Taiwan, Papuasia, Queensland, and the South Pacific.
Rhus copallinum, the winged sumac, shining sumac, dwarf sumac or flameleaf sumac, is a species of flowering plant in the cashew family (Anacardiaceae) that is native to eastern North America. It is a deciduous tree growing to 3.5–5.5 metres (11–18 ft) tall and an equal spread with a rounded crown. A 5-year-old sapling will stand about 2.5 metres (8.2 ft).
Rhus glabra, the smooth sumac, is a species of sumac in the family Anacardiaceae, native to North America, from southern Quebec west to southern British Columbia in Canada, and south to northern Florida and Arizona in the United States and Tamaulipas in northeastern Mexico.
Rhus aromatica, the fragrant sumac, is a deciduous shrub in the family Anacardiaceae native to North America. It is found in southern Canada and nearly all of the lower 48 states except peninsular Florida.
Anacardioideae is a subfamily of plants in the family Anacardiaceae.
The Amaryllidaceae are a family of herbaceous, mainly perennial and bulbous flowering plants in the monocot order Asparagales. The family takes its name from the genus Amaryllis and is commonly known as the amaryllis family. The leaves are usually linear, and the flowers are usually bisexual and symmetrical, arranged in umbels on the stem. The petals and sepals are undifferentiated as tepals, which may be fused at the base into a floral tube. Some also display a corona. Allyl sulfide compounds produce the characteristic odour of the onion subfamily (Allioideae).
Protorhus is a small genus of Afrotropical trees in the family Anacardiaceae. It is dioecious, with male and female flowers on separate plants.
Drimycarpus is a small genus of trees in the cashew and sumac family Anacardiaceae. The generic name is from the Greek meaning "pungent fruit".
Semecarpus cuneiformis is a tree in the cashew and sumac family Anacardiaceae. The specific epithet cuneiformis is from the Latin meaning 'wedge-shaped', referring to the leaf base.
Holigarna is a genus of trees in the subfamily Anacardioideae of the cashew and sumac family Anacardiaceae. They grow naturally in India, Bangladesh and Indo-China. Holigarna arnottiana may cause an allergic reaction and irritate the skin chemically. Inhaling this species' wood smoke may be hazardous.
