Rosaceae, the rose family, is a family of flowering plants that includes 4,828 known species in 91 genera.
The MaloideaeC.Weber was the apple subfamily, a grouping used by some taxonomists within the rose family, Rosaceae. Recent molecular phylogenetic evidence has shown that the traditional Spiraeoideae and Amygdaloideae form part of the same clade as the traditional Maloideae, and the correct name for this group is Amygdaloideae. Earlier circumscriptions of Maloideae are more-or-less equivalent to subtribe Malinae or to tribe Maleae. The group includes a number of plants bearing commercially important fruits, such as apples and pears, while others are cultivated as ornamentals.
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.
Sorbus is a genus of over 100 species of trees and shrubs in the rose family, Rosaceae. Species of Sorbus (s.l.) are commonly known as whitebeam, rowan, mountain-ash and service tree. The exact number of species is disputed depending on the circumscription of the genus, and also due to the number of apomictic microspecies, which some treat as distinct species, but others group in a smaller number of variable species. Recent treatments classify Sorbus in a narrower sense to include only the pinnate leaved species of subgenus Sorbus, raising several of the other subgenera to generic rank.
Celtis is a genus of about 60–70 species of deciduous trees, commonly known as hackberries or nettle trees, in the hemp family Cannabaceae. It has a cosmopolitan distribution.
Aronia is a genus of deciduous shrubs, the chokeberries, in the family Rosaceae native to eastern North America and most commonly found in wet woods and swamps. The genus Aronia is considered to have 3 species. The most common and widely used is Aronia melanocarpa which emerged from Eastern North America. The lesser known Aronia arbutifolia and the hybrid form of the abovementioned species called Aronia prunifolia were first cultivated in Central and Eastern North America. In the eighteenth century, the first shrubs of the best-known species Aronia melanocarpa reached Europe where they were first cultivated in Scandinavia and Russia.
Cercocarpus, commonly known as mountain mahogany, is a small genus of at least nine species of nitrogen-fixing flowering plants in the rose family, Rosaceae. They are native to the western United States and northern Mexico, where they grow in chaparral and semidesert habitats and climates, often at high altitudes. Several are found in the California chaparral and woodlands ecoregion.
Photinia is a genus of about 30 species of small trees and large shrubs, but the taxonomy has recently varied greatly, with the genera Heteromeles, Stranvaesia and Aronia sometimes included in Photinia.
Stranvaesia is a genus of flowering plants in the family Rosaceae. Its morphology is so similar to Photinia that it has sometimes been included within that genus, but recent molecular data indicate that the two genera are not related.
Mespilus, commonly called medlar, is a monotypic genus of flowering plants in the family Rosaceae containing the single species Mespilus germanica of southwest Asia. It is also found in some countries in the Balkans, especially in Albanian and Bulgarian regions, and in western parts of Caucasian Georgia. A second proposed species, Mespilus canescens, discovered in North America in 1990, proved to be a hybrid between M. germanica and one or more species of hawthorn, and is properly known as × Crataemespilus canescens.
Holodiscus discolor, commonly known as ocean spray or oceanspray, creambush, or ironwood, is a shrub of western North America.
Purshia is a small genus of 5–8 species of flowering plants in the family Rosaceae which are native to western North America.
Neillia is a genus of the botanical family Rosaceae. They are deciduous shrubs or subshrubs. They produce clusters of terminal or axillary flowers, and have dry dehiscent fruits. They are native to eastern and central Asia.
Vauquelinia, commonly known as the rosewoods, is a genus of the rose family, Rosaceae. It consists of two species of shrubs found in the southwestern United States and northwestern Mexico. The genus was named for French chemist Louis Nicolas Vauquelin (1763-1829). The nectar provided by these plants is commonly fed on by wasps such as Polistes instabilis.
Gillenia is a genus of two species of perennial herbs in the family Rosaceae, Gillenia stipulata and Gillenia trifoliata. Common names for plants in this genus include: Bowman's root, Indian-physic, American ipecac. This genus is endemic to dry open woods with acidic soils in eastern North America. Both plants are subshrubs with exposed semi-woody branches and serrated leaves; the larger lower leaves are divided into palmately arranged leaflets. Plants bloom in May, June, or July; blooms are composed of five slender white petals which are loosely arranged and typically appear slightly twisted and limp as if they were wilted. The flowers mature into small capsules. G. stipulata and G. trifoliata are often planted as ornamentals and used in herbal medicine.
Kageneckia is a genus of flowering plant in family Rosaceae.
Chamaebatiaria is a monotypic genus of aromatic shrub in the rose family containing the single species Chamaebatiaria millefolium, which is known by the common names fern bush and desert sweet. Its genus name comes from its physical resemblance to the mountain miseries of genus Chamaebatia, which are not closely related. This is a hairy, sticky plant covered in fernlike foliage made up of fronds of small leaflets. At the ends of the erect branches of this spreading bush are inflorescences of white roselike flowers. This shrub is a resident of scrub, woodland, and forests in western North America. The closest relative of Spiraeanthus.
Lindleya is a genus of Mexican evergreen trees of the family Rosaceae, tribe Maleae. The sole species, Lindleya mespiloides, grows to a height of 6 metres (20 ft) and bears solitary white fragrant flowers in summer. The fruit are dry dehiscent capsules.
Crataegus marshallii is a species of hawthorn known by the common name parsley hawthorn. It is native to the southeastern United States.
Holodiscus dumosus is a species of flowering plant in the rose family, with the common names mountain spray, rock-spiraea, bush oceanspray, and glandular oceanspray.
