'''Prunus''' is a [[genus]] of [[tree]]s and [[shrub]]s, including the [[plum]]s, [[cherry|cherries]], [[peach]]es, [[apricot]]s and [[almond]]s. It is traditionally placed within the [[rose]] family [[Rosaceae]] as a [[subfamily]], the [[Prunoideae]] (or [[Amygdaloideae]]), but sometimes placed in its own family, the [[Prunaceae]] (or Amygdalaceae). There are several hundred species of ''Prunus'', spread throughout the northern temperate regions of the globe.
−
Amygdalus (Greek-made name, referring to the furrowed pit). Rosàceae. A name given to the peaches, apricots and their kin, but here treated as a section of the genus Prunus, which see.

The flowers are usually white to pink, with five [[petal]]s and five [[sepal]]s. They are borne singly, or in [[umbel]]s of two to six or more on [[raceme]]s. The fruit of all ''Prunus'' species is a [[drupe]] with a relatively large "stone". Leaves are simple and usually [[leaf shape|lanceolate]], unlobed and toothed along the margin.
 +
 
 +
The genus ''Prunus'' includes the [[almond]], [[apricot]], [[cherry]], [[peach]] and [[plum]], all of which have [[cultivar]]s developed for commercial [[fruit]] production. The edible part of the almond is the seed; the almond fruit is a drupe and not a "[[Nut (fruit)|nut]]". There are also a number of species, [[hybrid]]s, and [[cultivar]]s grown strictly as [[ornamental plant]]s, usually for their profusion of flowers, occasionally for leaves and bark. These ornamentals include the group that may be collectively called ''flowering cherries''.
 +
 
 +
Because of their considerable value as both food and ornamental plants, many ''Prunus'' species have been [[introduced species|introduced]] to parts of the world to which they are not native. Many of the Old World species are grown for ornament or fruit, and have been planted throughout the world; and some have become naturalised beyond their native range.

 +
**Subgenus ''Prunus'': [[plum]]s and [[apricot]]s. Axillary buds solitary. Flowers in early spring stalked, not on leafed shoots. Fruit with a groove along one side; stone rough. Type species ''Prunus domestica'' (Plum).
 +
**Subgenus ''Cerasus'': [[cherry|cherries]]. Axillary buds single. Flowers in early spring in corymbs, long-stalked, not on leafed shoots. Fruit not grooved; stone smooth. Type species ''Prunus cerasus'' (Sour cherry).
 +
**Subgenus ''Lithocerasus'': [[dwarf cherry|dwarf cherries]]. Axillary buds in threes. Flowers in early spring in corymbs, long-stalked, not on leafed shoots. Fruit not grooved; stone smooth. Type species ''Prunus pumila'' (Sand cherry).
 +

In very recent years, the knowledge of the genus has been greatly extended by explorations in China, whence many new species (particularly in the subgenera Cera- sus and Padus) have been derived that will probably find their way into cultivation. The taxonomy of the American native plums has also received much recent attention. Aside from the older writings of Bailey and Waugh on the native edible plums and cherries, see Hedrick,&quot;The Plums of New York,&quot; 1911, and &quot;The Cherries of New York,&quot; 1915 (also with similar accounts of all other pomological species), and Wight,&quot;Varieties of Plums Derived from Native American Species,&quot; Bulletin No. 172, Bureau of Plant Industry, United States Department of Agriculture, 1915, and &quot;Native American Species of Prunus,&quot; Bulletin No. 179 (1915). For the oriental Prunus, particularly those native in China, see the work by Koehne and others in &quot;Plantae Wilsonianae,&quot; vol. 1, 1911-1913, and Wilson's &quot;Cherries of Japan&quot; (1916), published by the Arnold Arboretum, Boston. As this writing is being closed in the printery, a paper on the Japanese cherries appears in Japan: Miyoshi, &quot;Japanische Bergkirschen, in Journ. Coll.Sci. Tokyo, vol. 34, art. 1 (1916) with eighty-nine colored figures.

'''Prunus''' is a [[genus]] of [[tree]]s and [[shrub]]s, including the [[plum]]s, [[cherry|cherries]], [[peach]]es, [[apricot]]s and [[almond]]s. It is traditionally placed within the [[rose]] family [[Rosaceae]] as a [[subfamily]], the [[Prunoideae]] (or [[Amygdaloideae]]), but sometimes placed in its own family, the [[Prunaceae]] (or Amygdalaceae). There are several hundred species of ''Prunus'', spread throughout the northern temperate regions of the globe.

The flowers are usually white to pink, with five [[petal]]s and five [[sepal]]s. They are borne singly, or in [[umbel]]s of two to six or more on [[raceme]]s. The fruit of all ''Prunus'' species is a [[drupe]] with a relatively large &quot;stone&quot;. Leaves are simple and usually [[leaf shape|lanceolate]], unlobed and toothed along the margin.

Some treatments break the genus up into several different genera, but this segregation is not widely recognised other than at the subgeneric rank. [[Integrated Taxonomic Information System|ITIS]] recognises just the single Genus ''Prunus'', with the incomplete list of [[species]] as shown in the box on the right.

*'''''Prunus'' subgenera:'''
 
−
**Subgenus ''Amygdalus'': [[almond]]s and [[peach]]es. Axillary buds in threes (vegetative bud central, two flower buds to sides). Flowers in early spring, sessile or nearly so, not on leafed shoots. Fruit with a groove along one side; stone deeply grooved. Type species ''Prunus dulcis'' (Almond).
 
−
**Subgenus ''Prunus'': [[plum]]s and [[apricot]]s. Axillary buds solitary. Flowers in early spring stalked, not on leafed shoots. Fruit with a groove along one side; stone rough. Type species ''Prunus domestica'' (Plum).
 
−
**Subgenus ''Cerasus'': [[cherry|cherries]]. Axillary buds single. Flowers in early spring in corymbs, long-stalked, not on leafed shoots. Fruit not grooved; stone smooth. Type species ''Prunus cerasus'' (Sour cherry).
 
−
**Subgenus ''Lithocerasus'': [[dwarf cherry|dwarf cherries]]. Axillary buds in threes. Flowers in early spring in corymbs, long-stalked, not on leafed shoots. Fruit not grooved; stone smooth. Type species ''Prunus pumila'' (Sand cherry).
 
−
**Subgenus ''Padus'': [[bird cherry|bird cherries]]. Axillary buds single. Flowers in late spring in racemes on leafy shoots, short-stalked. Fruit not grooved; stone smooth. Type species ''Prunus padus'' (European bird cherry).
 
−
**Subgenus ''Laurocerasus'': [[cherry-laurel]]s. Axillary buds single. Flowers in early spring in racemes, not on leafed shoots, short-stalked. Fruit not grooved; stone smooth. Mostly [[evergreen]] (all the other subgenera are [[deciduous]]). Type species ''Prunus laurocerasus'' (European cherry-laurel).

−
==Uses==
 
−
The genus ''Prunus'' includes the [[almond]], [[apricot]], [[cherry]], [[peach]] and [[plum]], all of which have [[cultivar]]s developed for commercial [[fruit]] production. The edible part of the almond is the seed; the almond fruit is a drupe and not a &quot;[[Nut (fruit)|nut]]&quot;. There are also a number of species, [[hybrid]]s, and [[cultivar]]s grown strictly as [[ornamental plant]]s, usually for their profusion of flowers, occasionally for leaves and bark. These ornamentals include the group that may be collectively called ''flowering cherries''.

[[Pygeum]] is a herbal remedy containing extracts from the bark of ''[[Prunus africana]]''. It is used as to alleviate some of the discomfort caused by inflammation in patients suffering from [[benign prostatic hyperplasia]].
 
−
 
 
−
Because of their considerable value as both food and ornamental plants, many ''Prunus'' species have been [[introduced species|introduced]] to parts of the world to which they are not native. Many of the Old World species are grown for ornament or fruit, and have been planted throughout the world; and some have become naturalised beyond their native range.

''Prunus'' species are used as food plants for the [[larva]]e of a large number of [[Lepidoptera]] species - see [[list of Lepidoptera which feed on Prunus]].

Prunus is a genus of trees and shrubs, including the plums, cherries, peaches, apricots and almonds. It is traditionally placed within the rose family Rosaceae as a subfamily, the Prunoideae (or Amygdaloideae), but sometimes placed in its own family, the Prunaceae (or Amygdalaceae). There are several hundred species of Prunus, spread throughout the northern temperate regions of the globe.

The flowers are usually white to pink, with five petals and five sepals. They are borne singly, or in umbels of two to six or more on racemes. The fruit of all Prunus species is a drupe with a relatively large "stone". Leaves are simple and usually lanceolate, unlobed and toothed along the margin.

The genus Prunus includes the almond, apricot, cherry, peach and plum, all of which have cultivars developed for commercial fruit production. The edible part of the almond is the seed; the almond fruit is a drupe and not a "nut". There are also a number of species, hybrids, and cultivars grown strictly as ornamental plants, usually for their profusion of flowers, occasionally for leaves and bark. These ornamentals include the group that may be collectively called flowering cherries.

Because of their considerable value as both food and ornamental plants, many Prunus species have been introduced to parts of the world to which they are not native. Many of the Old World species are grown for ornament or fruit, and have been planted throughout the world; and some have become naturalised beyond their native range.

Classification

Some treatments break the genus up into several different genera, but this segregation is not widely recognised other than at the subgeneric rank. ITIS recognises just the single Genus Prunus, with the incomplete list of species as shown in the box on the right.

  • Prunus subgenera:
    • Subgenus Amygdalus: almonds and peaches. Axillary buds in threes (vegetative bud central, two flower buds to sides). Flowers in early spring, sessile or nearly so, not on leafed shoots. Fruit with a groove along one side; stone deeply grooved. Type species Prunus dulcis (Almond).
    • Subgenus Prunus: plums and apricots. Axillary buds solitary. Flowers in early spring stalked, not on leafed shoots. Fruit with a groove along one side; stone rough. Type species Prunus domestica (Plum).
    • Subgenus Cerasus: cherries. Axillary buds single. Flowers in early spring in corymbs, long-stalked, not on leafed shoots. Fruit not grooved; stone smooth. Type species Prunus cerasus (Sour cherry).
    • Subgenus Lithocerasus: dwarf cherries. Axillary buds in threes. Flowers in early spring in corymbs, long-stalked, not on leafed shoots. Fruit not grooved; stone smooth. Type species Prunus pumila (Sand cherry).
    • Subgenus Padus: bird cherries. Axillary buds single. Flowers in late spring in racemes on leafy shoots, short-stalked. Fruit not grooved; stone smooth. Type species Prunus padus (European bird cherry).
    • Subgenus Laurocerasus: cherry-laurels. Axillary buds single. Flowers in early spring in racemes, not on leafed shoots, short-stalked. Fruit not grooved; stone smooth. Mostly evergreen (all the other subgenera are deciduous). Type species Prunus laurocerasus (European cherry-laurel).
