Rosales is an order of flowering plants. It is sister to a clade consisting of Fagales and Cucurbitales. It contains about 7,700 species, distributed into about 260 genera. Rosales comprise nine families, the type family being the rose family, Rosaceae. The largest of these families are Rosaceae (91/4828) and Urticaceae (53/2625). The order Rosales is divided into three clades that have never been assigned a taxonomic rank. The basal clade consists of the family Rosaceae; another clade consists of four families, including Rhamnaceae; and the third clade consists of the four urticalean families.
Rosaceae, the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera.
Amygdaloideae is a subfamily within the flowering plant family Rosaceae. It was formerly considered by some authors to be separate from Rosaceae, and the family names Prunaceae and Amygdalaceae have been used. Reanalysis from 2007 has shown that the previous definition of subfamily Spiraeoideae was paraphyletic. To solve this problem, a larger subfamily was defined that includes the former Amygdaloideae, Spiraeoideae, and Maloideae. This subfamily, however, is to be called Amygdaloideae rather than Spiraeoideae under the International Code of Nomenclature for algae, fungi, and plants as updated in 2011.
An apricot is a fruit, or the tree that bears the fruit, of several species in the genus Prunus.
A plum is a fruit of some species in Prunus subg. Prunus. Dried plums are often called prunes, though in the United States they may be labeled as 'dried plums', especially during the 21st century.
Prunus is a genus of trees and shrubs in the flowering plant family Rosaceae that includes plums, cherries, peaches, nectarines, apricots, and almonds. The genus has a cosmopolitan distribution, being native to the North American temperate regions, the neotropics of South America, and temperate and tropical regions of Eurasia and Africa, There are about 340 accepted species as of March 2024. Many members of the genus are widely cultivated for their fruit and for decorative purposes. Prunus fruit are drupes, or stone fruits. The fleshy mesocarp surrounding the endocarp is edible while the endocarp itself forms a hard, inedible shell called the pyrena. This shell encloses the seed, which is edible in some species, but poisonous in many others. Besides being eaten off the hand, most Prunus fruit are also commonly used in processing, such as jam production, canning, drying, and the seeds for roasting.
Prunus armeniaca is the most commonly cultivated apricot species. The native range is somewhat uncertain due to its extensive prehistoric cultivation. Genetic studies indicate Central Asia is the center of origin. It is extensively cultivated in many countries and has escaped into the wild in many places.
Prunus subg. Padus is a subgenus of Prunus, characterised by having racemose inflorescences. Padus was originally a distinct genus, but genetic and morphological studies have shown that Padus is polyphyletic. It has been proposed that all the racemose taxa within Prunus are incorporated into a broad-sense Prunus subg. Padus.
Prunus serotina, commonly called black cherry, wild black cherry, rum cherry, or mountain black cherry, is a deciduous tree or shrub in the rose family Rosaceae. Despite being called black cherry, it is not very closely related to the commonly cultivated cherries, such as sweet cherry, sour cherry and Japanese flowering cherries, which belong to Prunus subg. Cerasus. Instead, P. serotina belongs to Prunus subg. Padus, a subgenus also including Eurasian bird cherry and chokecherry. The species is widespread and common in North America and South America.
Prunus mexicana, commonly known as the Mexican plum, Inch plum, and Bigtree plum, is a North American species of plum tree that can be found in the central United States and Northern Mexico.
Prunus tenella, the dwarf Russian almond, is a species of deciduous shrub in the genus Prunus, native to steppes of Eastern Europe and Western Siberia, as well as dry open sites of Caucasus, Western and Central Asia.
Prunus sect. Prunocerasus is a section of the genus Prunus. Koehne originally described it as comprising the North American plums and placed it in the subgenus Cerasus. The section is now generally recognized as belonging to Prunus subg. Prunus.
Prunus brigantina, called Briançon apricot, Briançon plum, marmot plum, and Alpine apricot, is a wild tree species native to France and Italy. Its fruit is edible and similar to the commercial apricot P. armeniaca, but it is smooth unlike apricots. An edible oil produced from the seed, 'huile des marmottes', is used in France.
Prunus tianshanica, the Tianshan cherry, is a species of cherry native to the Tianshan Mountains of Central Asia, preferring to grow at 800-1000 m.
Prunus brachypetala is a species of bush cherry native to Turkey, Iraq and Iran. Its fruit are edible and consumed locally.
Prunus tangutica is a species of wild peach native to China. Based on its fruit traits it had been considered a wild almond, but genetic and morphological studies have shown that it is more closely related to Prunus persica, the cultivated peach, with its closest relative being Prunus mongolica. It is a very dense spiny shrub or shrubby tree, usually 1 to 2.5 m tall but reaching 4 m, preferring to grow on sunny slopes and alongside streams at 1500 to 2600 m, but found as high as 3400 m. Its flower petals are a pale pink, and its velutinous (velvety) fruit are green when unripe and purplish‑red when ripe. The fruits' mesocarps splits when ripe, which led to it being classified as an almond for over a century, with the exception of Kovalev & Kostina in 1935, who assigned it to Persica.
Prunus subg. Cerasus is a subgenus of Prunus. Species of the subgenus have a single winter bud per axil. The flowers are usually in small corymbs or umbels of several together, but some species have short racemes. The fruit is a drupe and has no obvious groove along the side. The subgenus is native to the temperate regions of the Northern Hemisphere, with two species in North America, four in Europe, two in North Africa, and the remainder in Asia.
Prunus sect. Microcerasus is a section of Prunus. It used to be included in Prunus subg. Cerasus, but phylogenetic research indicates it belongs to Prunus subg. Prunus. It differs from Prunus subg. Cerasus by having three winter buds per axil.
Prunus sect. Prunus is a section of Prunus subg. Prunus. It contains species of Eurasian plum.
Candidatus Phytoplasma pruni is a species of phytoplasma in the class Mollicutes, a class of bacteria distinguished by the absence of a cell wall. The specific epithet pruni means "living on Prunus", emphasizing the fact that the phytoplasma is a parasite of various Prunus species, otherwise known as stone fruits. The phytoplasma is commonly called the X-disease phytoplasma.
