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, one-seed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family Rosaceae. It is native to Europe, northwestern Africa, and West Asia, but has been introduced in many other parts of the world.
Crataegus heterophylla, known as the various-leaved hawthorn, is of uncertain origin. Its original native range is not known, possibly it was the Caucasus of Western Asia. Suggestions that it originated in Southeast Europe may be based on misidentification.
The name Crataegus oxyacantha L. has been rejected as being of uncertain application, but is sometimes still used.
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.
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.
Stigmella crataegella is a moth of the family Nepticulidae found in Europe. It was described by the Austrian entomologist Josef Wilhelm Klimesch in 1936. The larvae mine the leaves of hawthorns.
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.
Dasineura crataegi, the hawthorn button-top gall-midge, is a dipteran gall-midge. It causes the hawthorn button-top gall, which develops in the terminal shoots of common hawthorn, Crataegus monogyna Jacq., Midland hawthorn C laevigata (Poir.) DC and their hybrid, C × media Bechst. Synonyms are Perrisia crataegi and Cecidomyia crataegi.
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.
Spuleria is a genus of moths of the family Elachistidae. It contains only one species Spuleria flavicaput, which is found in most of Europe and Anatolia.
× 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.
