Crataegus, commonly called hawthorn, quickthorn, thornapple, May-tree, whitethorn, Mayflower 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, whitethorn,one-seed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family, Rosaceae. It grows to about 10 metres tall, producing hermaphrodite flowers in late spring. The berry-like pomes contain a stone-encased seed.
The name Crataegus oxyacantha L. has been rejected as being of uncertain application, but is sometimes still used.
Crataegus brachyacantha is one of the "black-fruited" species of hawthorn, but it is only very distantly related to the other black-fruited species such as C. douglasii or C. nigra. The common names blueberry haw and blueberry hawthorn refer to the appearance of the fruit, which are almost blue, and does not refer to their taste. The species is rarely cultivated but has ornamental leaves, flowers, and foliage. It is native to Louisiana, and also occurs just across the border of neighbouring states.
Crataegus × lavalleei, sometimes known as hybrid cockspurthorn or Lavallée's hawthorn, is a hybrid that arose between cultivated specimens of two species in the genus Crataegus (Hawthorn). It is an ornamental small tree with glossy dark green unlobed leaves that is used horticulturally.
Crataegus punctata is a species of hawthorn known by the common names dotted hawthorn or white haw that is native to most of the eastern United States and eastern Canada. While some sources claim it is the state flower of Missouri, the actual legislation does not identify an exact species. Furthermore, the Missouri Department of Conservation asserts the Crataegus mollis was specifically designated as the state flower.
Crataegus rhipidophylla is a species of hawthorn which occurs naturally from southern Scandinavia and the Baltic region to France, the Balkan Peninsula, Turkey, Caucasia, and Ukraine. It is poorly known as a landscape and garden plant, but seems to have potential for those uses.
Crataegus × media, is a hybrid between two species in the genus Crataegus (Hawthorn), C. monogyna and C. laevigata, both in series Crataegus. Under the rules of botanical nomenclature the name C. × media covers all intermediate forms between the two parent species, including backcrosses.
Crataegus × macrocarpa, is a hybrid between two species of Crataegus (hawthorn), C. laevigata and C. rhipidophylla, both in series Crataegus. A chemotaxonomic investigation comparing flavonoid patterns in C. × macrocarpa and its putative parent species corroborated their supposed relationship. It is sometimes confused with C. × media, the hybrid between C. monogyna and C. laevigata.
Phyllonorycter oxyacanthae is a moth of the family Gracillariidae found in all of Europe except the Balkan Peninsula. It was described by the German-born Swiss entomologist, Heinrich Frey in 1856. The larvae are known as leaf miners, living inside the leaves of their food plants.
Crataegus × ariifolia is an ornamental hybrid hawthorn that is used in horticulture. Its name refers to a similarity of its leaves to the genus Aria.
Stigmella oxyacanthella is a moth of the family Nepticulidae, found in Europe and North America. The larvae are leaf miners feeding inside the leaves of trees and shrubs, such as hawthorn, apple and pear.
Stigmella hybnerella also known as the greenish thorn pigmy is a moth of the family Nepticulidae. It is found in all of Europe, in North Africa, the Near East, and the eastern part of the Palearctic realm. The larvae mine the leaves of trees and shrubs such as hawthorns and rowans.
Stigmella regiella is a moth of the family Nepticulidae. It is found in most of Europe, east to the eastern part of the Palearctic realm.
Ectoedemia atricollis is a moth of the family Nepticulidae found in Asia and Europe. It was described by the English entomologist Henry Tibbats Stainton in 1857.
Phyllonorycter corylifoliella, the hawthorn red midget moth, is a moth of the family Gracillariidae. It is found in all of Europe.
C. laevigata may refer to:
Blastodacna hellerella is a moth in the family Elachistidae. It is found in most of Europe except the north. In the east, the range extends to the Caucasus.
Bucculatrix bechsteinella is a moth of the family Bucculatricidae. It was described by Johann Matthäus Bechstein and Georg Ludwig Scharfenberg in 1805. It is found in most of Europe, except Greece and Bulgaria.
× Crataemespilus is the generic name applied to hybrids between the genera Crataegus and Mespilus. It should not be confused with + Crataegomespilus, which is applied to graft-chimeras between those genera.
