Crataegus ucrainica is a putative species of hawthorn found in Ukraine. [2] A 2014 molecular and morphological study reduced it to a synonym of Crataegus meyeri . [3]
Rosaceae, the rose family, is a medium-sized family of flowering plants, including 4,828 known species in 91 genera.
Crataegus, commonly called hawthorn, quickthorn, thornapple, May-tree, whitethorn, or hawberry, is a genus of several hundred species of shrubs and trees in the family Rosaceae, native to temperate regions of the Northern Hemisphere in Europe, Asia, North Africa, and North America. The name "hawthorn" was originally applied to the species native to northern Europe, especially the common hawthorn C. monogyna, and the unmodified name is often so used in Britain and Ireland. The name is now also applied to the entire genus and to the related Asian genus Rhaphiolepis.
Crataegus monogyna, known as common hawthorn, oneseed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family Rosaceae. It is native to Europe, northwest Africa and West Asia but has been introduced in many other parts of the world.
Crataegus mollis, known as downy hawthorn or red hawthorn, occurs in eastern North America from southeastern North Dakota east to Nova Scotia and southwest to eastern Texas. The range of this species is from southern Ontario and Michigan to eastern North Dakota and southward to Denison, Texas, and Arizona. This tree inhabits wooded bottomlands, the prairie border, and the midwest savanna understorey.
Crataegus laevigata, known as the midland hawthorn, English hawthorn, woodland hawthorn or mayflower, is a species of hawthorn native to western and central Europe, from Great Britain and Spain east to the Czech Republic and Hungary. It is also present in North Africa. The species name is sometimes spelt C. levigata, but the original orthography is C. lævigata.
Crataegus azarolus is a species of hawthorn known by the common names azarole, azerole, and Mediterranean medlar. It is native to the Mediterranean Basin and is a common plant there, growing on sites comparable to those the European common hawthorn grows on. In the Arab countries it is the commonest of the hawthorn species. When growing in the wild the azerole bears plentiful crops of haw fruits, which are similar to the haws of the European common hawthorn, but plumper.
Crataegus crus-galli is a species of hawthorn known by the common names cockspur hawthorn and cockspur thorn. It is native to eastern North America from Ontario to Texas to Florida, and it is widely used in horticulture. It is thought to be the parent, along with Crataegus succulenta, of the tetraploid species Crataegus persimilis.
Crataegus submollis, known as the northern downy hawthorn, northern red haw, Quebec hawthorn, or hairy cockspurthorn, is a species of hawthorn that grows to about 7 m in height and typically carries large crops of red fruit.
Crataegus coccinea, the scarlet hawthorn, is a species of hawthorn around which there is considerable confusion because the name has been misapplied for a long time. It has been shown to be the same as C. pedicellata, and under the rules of botanical nomenclature, the older name should be used.
The Kazantypskyi Nature Reserve is a small reserve in the Lenine Raion on the Kerch Peninsula in Crimea. The reserve includes both territory of Cape Kazantyp and coast-aquatic-complex.
Series Molles is a series within the genus Crataegus that contains at least six species of hawthorn trees and shrubs, native to Eastern North America. Some of the species are cultivated as ornamental plants. They have relatively large leaves, large flowers, and bloom early for hawthorns. The plant parts are usually hairy, particularly in early growth, and the fruit are generally red and are large for hawthorn fruit.
Series Populneae is a series within the genus Crataegus that contains at least eight species of hawthorn trees and shrubs, native to Eastern North America. Only one species, C. populnea is widespread.
Section Coccineae is a section within the genus Crataegus that includes the majority of North American hawthorn diversity. It includes at least 20 series as well as some species that have not yet been assigned to series.
Series Pruinosae is a series within the genus Crataegus that contains at least six species of hawthorn trees and shrubs, native to Eastern North America. They are similar in some respects to series Intricatae. They are very thorny, with medium to large leaves, and hard fruit that are usually pinkish in colour.
Series Tenuifoliae is a series within the genus Crataegus that contains at least seven species of hawthorn trees and shrubs, native to Eastern North America, with one disjunct species in the mountains of New Mexico.
Willard Webster Eggleston was an American botanist, employed by the United States Department of Agriculture Bureau of Plant Industry. He graduated from Dartmouth College in 1891 with a Bachelor of Science degree. In his work on the taxonomy of Crataegus, now known to be complicated by apomixis, polyploidy, and hybridization, he aimed to simplify, counteracting the proliferation of species names that other botanists had produced.
Crataegus meyeri is a species of hawthorn found in Belarus, European Russia, Ukraine including Crimea, Anatolia, the Transcaucasus, Iraq and Iran. Trees, they are found in scrubby areas and forest openings on drier mountain slopes, typically in association with Quercus. A 2014 molecular and morphological study reduced Crataegus ucrainica and Crataegus × yosgatica to synonyms of Crataegus meyeri.
Crataegus × yosgatica or Crataegus yosgatica is a putative hybrid species of hawthorn. It was thought to be a cross between Crataegus monogyna and C. tanacetifolia. A 2014 molecular and morphological study reduced it to a synonym of Crataegus meyeri.
Crataegus turkestanica, the Turkestan hawthorn, is a species of hawthorn found in Central Asia, Afghanistan and Iran. They are typically found in association with Juglans regia. Some authorities have it as a synonym of Crataegus pseudoheterophylla subsp. turkestanica.
Crataegus pseudoheterophylla is a species of hawthorn found in Anatolia, the Transcaucasus, Iran and Afghanistan. They are trees or shrubs that are typically found on scrubby mountain slopes.
