Castanea ozarkensis, also known as the Ozark chinkapin (also spelled chinquapin), is a species of tree that is native to the United States. [3] It is in the Castanea genus that includes chestnuts and types of chestnut known as chinkapins.
Castanea ozarkensis was described by William Willard Ashe and published in the Bulletin of the Torrey Botanical Club 50 (11): 360-361. 1923. [4]
Some authorities consider it a variant of the Allegheny chinkapin (C. pumila) as C. pumila ozarkensis.
It grows in the Ozark Mountains and Ouachita Mountains of Missouri, Arkansas, Texas, Louisiana and Oklahoma. [3] It is possibly extirpated from Alabama.
The nuts it produces provided food for indigenous people, early settlers, and various animals including eastern gray squirrel, chipmunk, white-tailed deer, turkey, and bobwhite quail. [3]
Castanea ozarkensis is susceptible to chestnut blight and has been devastated by the disease, and largely now grows only as a small tree or shrub. [3] However, several mature individuals have survived the blight, with over 45 such individuals located so far since the 2000s. The discovery of these specimens has spurred an ongoing project to restore the species by using the offspring of these trees, headed by the Ozark Chinkapin Foundation. [5] An analysis has also found that Ozark chinkapin populations contain far more genetic diversity than those of the American chestnut, which was also devastated by the chestnut blight. The study also found that the Ozark chinkapin may actually be ancestral to the American chestnut and Allegheny chinkapin, rather than the other way around. [6] [5] Another study has found that the surviving Ozark chinkapins are even more resistant to the chestnut blight than the Chinese chestnut, which is not affected by the blight. [5]
A large individual, designated a Champion Tree, grows in Barry County, Missouri. [7]
Quercus montana, the chestnut oak, is a species of oak in the white oak group, Quercus sect. Quercus. It is native to the eastern United States, where it is one of the most important ridgetop trees from southern Maine southwest to central Mississippi, with an outlying northwestern population in southern Michigan. It is also sometimes called rock oak because of its presence in montane and other rocky habitats.
The chestnuts are the deciduous trees and shrubs in the genus Castanea, in the beech family Fagaceae. The name also refers to the edible nuts they produce. They are native to temperate regions of the Northern Hemisphere.
The American chestnut is a large, fast-growing deciduous tree of the beech family native to eastern North America. As is true of all species in the genus Castanea, the American chestnut produces burred fruit with edible nuts. The American chestnut was once one of the most important forest trees throughout its range.
The pathogenic fungus Cryphonectria parasitica is a member of the Ascomycota. This necrotrophic fungus is native to East Asia and South East Asia and was introduced into Europe and North America in the early 1900s. The fungus spread rapidly and caused significant tree loss in both regions.
The Fagaceae are a family of flowering plants that includes beeches, chestnuts and oaks, and comprises eight genera with about 927 species. Fagaceae in temperate regions are mostly deciduous, whereas in the tropics, many species occur as evergreen trees and shrubs. They are characterized by alternate simple leaves with pinnate venation, unisexual flowers in the form of catkins, and fruit in the form of cup-like (cupule) nuts. Their leaves are often lobed, and both petioles and stipules are generally present. Their fruits lack endosperm and lie in a scaly or spiny husk that may or may not enclose the entire nut, which may consist of one to seven seeds. In the oaks, genus Quercus, the fruit is a non-valved nut called an acorn. The husk of the acorn in most oaks only forms a cup in which the nut sits. Other members of the family have fully enclosed nuts. Fagaceae is one of the most ecologically important woody plant families in the Northern Hemisphere, as oaks form the backbone of temperate forest in North America, Europe, and Asia, and are one of the most significant sources of wildlife food.
Quercus muehlenbergii, the chinquapinoak, is a deciduous species of tree in the white oak group. The species was often called Quercus acuminata in older literature. Quercus muehlenbergii is native to eastern and central North America. It ranges from Vermont to Minnesota, south to the Florida panhandle, and west to New Mexico in the United States. In Canada it is only found in southern Ontario, and in Mexico it ranges from Coahuila south to Hidalgo.
Castanea sativa, the sweet chestnut, Spanish chestnut or just chestnut, is a species of tree in the family Fagaceae, native to Southern Europe and Asia Minor, and widely cultivated throughout the temperate world. A substantial, long-lived deciduous tree, it produces an edible seed, the chestnut, which has been used in cooking since ancient times.
Quercus michauxii, the swamp chestnut oak, is a species of oak in the white oak section Quercus section Quercus in the beech family. It is native to bottomlands and wetlands in the southeastern and midwestern United States, in coastal states from New Jersey to Texas, inland primarily in the Mississippi–Ohio Valley as far as Oklahoma, Missouri, Illinois, and Indiana.
Chrysolepis is a small genus of plants in the family Fagaceae, endemic to the western United States. Its two species have the common name chinquapin. The genus occurs from western Washington south to the Transverse Ranges in Southern California, and east into Nevada.
Castanopsis, commonly called chinquapin or chinkapin, is a genus of evergreen trees belonging to the beech family, Fagaceae. The genus contains about 140 species, which are today restricted to tropical and subtropical eastern Asia. A total of 58 species are native to China, with 30 endemic; the other species occur further south, through Indochina to Indonesia and the Philippines, mountainous areas of Taiwan, and also in Japan. The English name chinkapin is shared with other related plants, including the golden chinkapins of the Pacific United States, which are sometimes included within Castanopsis but are more often considered a separate but very closely related genus, Chrysolepis.
The American Chestnut Foundation (TACF) is a nonprofit American organization dedicated to breeding a blight-resistant American chestnut tree and the reintroduction of this tree to the forests of the Eastern United States.
Castanea crenata, the Japanese chestnut or Korean chestnut, is a species of chestnut native to Japan and Korea. Castanea crenata exhibits resistance to Phytophthora cinnamomi, the fungal pathogen that causes ink disease in several Castanea species. The mechanism of resistance of Castanea crenata to Phytophthora cinnamomi may derive from its expression of the Cast_Gnk2-like gene.
Castanea pumila, commonly known as the Allegheny chinquapin, American chinquapin or dwarf chestnut, is a species of chestnut native to the southeastern United States. The native range is from Massachusetts and New York to Maryland and extreme southern New Jersey and southeast Pennsylvania south to central Florida, west to eastern Texas, and north to southern Missouri and Kentucky. The plant's habitat is dry sandy and rocky uplands and ridges mixed with oak and hickory to 1000 m elevation. It grows best on well-drained soils in full sun or partial shade.
Castanea mollissima, also known as the Chinese chestnut, is a species of chestnut tree in the family Fagaceae that is native to China, Taiwan, and Korea.
Chinquapin or chinkapin may refer to:
Quercus prinoides, commonly known as dwarf chinkapin oak, dwarf chinquapin oak, dwarf chestnut oak or scrub chestnut oak, is a shrubby, clone-forming oak native to central-eastern North America.
Dryocosmus kuriphilus is a species of gall wasp known by the common names chestnut gall wasp, Oriental chestnut gall wasp, and Asian chestnut gall wasp. It is native to China and it is known in many other parts of the world, particularly the Northern Hemisphere, as an introduced species and an invasive horticultural pest. It attacks many species of chestnut, including most cultivated varieties. It is considered the world's worst pest of chestnuts.
Castanea × neglecta, the chinknut, is a named hybrid chestnut tree; it is a cross between Castanea dentata and Castanea pumila. It was first formally named by Louis-Albert Dode in 1908. The chinknut is native to the southeastern United States.
Atymna castaneae is a species of treehopper belonging to the subfamily Smiliinae. It was first described by Asa Fitch in 1851.
