Juglandaceae
The Juglandaceae are a plant family known as the walnut family. They are trees, or sometimes shrubs, in the order Fagales. Members of this family are native to the Americas, Eurasia, and Southeast Asia. The nine or ten genera in the family have a total of around 50 species, and include the commercially important nut-producing trees walnut (''Juglans''), pecan (''Carya illinoinensis''), and hickory (''Carya''). The Persian walnut, '' Juglans regia'', is one of the major nut crops of the world. Walnut, hickory, and gaulin are also valuable timber trees while pecan wood is also valued as cooking fuel. Description Members of the walnut family have large, aromatic leaves that are usually alternate, but opposite in '' Alfaroa'' and '' Oreomunnea''. The leaves are pinnately compound or ternate, and usually 20–100 cm long. The trees are wind-pollinated, and the flowers are usually arranged in catkins. The fruits of the Juglandaceae are often confused with drupes but are acc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juglans
Walnut trees are any species of tree in the plant genus ''Juglans'', the type genus of the family Juglandaceae, the seeds of which are referred to as walnuts. All species are deciduous trees, tall, with pinnate leaves , with 5–25 leaflets; the shoots have chambered pith, a character shared with the wingnuts (''Pterocarya''), but not the hickories (''Carya'') in the same family. The 21 species in the genus range across the north temperate Old World from southeast Europe east to Japan, and more widely in the New World from southeast Canada west to California and south to Argentina. Edible walnuts, which are consumed worldwide, are usually harvested from cultivated varieties of the species '' Juglans regia''. China produces half of the world total of walnuts. Etymology The common name ''walnut'' derives from Old English ''wealhhnutu'', literally 'foreign nut' (from ''wealh'' 'foreign' + ''hnutu'' 'nut'), because it was introduced from Gaul and Italy.

Platycarya
''Platycarya'' is a genus of flowering plants in the family Juglandaceae native to eastern Asia in China, Korea, and Japan.Flora of China''Platycarya''/ref>Flora of China''Platycarya strobilacea''/ref> It is a deciduous tree growing to 15 m tall. The leaves are usually pinnate, 15–30 cm long with 7–15 leaflets (rarely simple, or with up to 23 leaflets), the terminal leaflet present; the leaflets are 3–11 cm long and 1.5–3.5 cm broad. The flowers are presented as catkins; the male (pollen) catkins are 2–15 cm long, the female catkins 2.5–5 cm long at maturity, hard and woody, superficially resembling a conifer cone with spirally arranged scales. The genus was formerly treated as comprising a single species '' Platycarya strobilacea'', though the second living species '' Platycarya longzhouensis'' is now recognized. A number of fossil species have been discovered across the Northern Hemisphere dating from the Early Eocene, although they bec ...

Pecan
The pecan (''Carya illinoinensis'') is a species of hickory native to the southern United States and northern Mexico in the region of the Mississippi River. The tree is cultivated for its seed in the southern United States, primarily in Georgia, New Mexico, Texas, and Mexico, which produces nearly half of the world total. The seed is an edible nut used as a snack and in various recipes, such as praline candy and pecan pie. The pecan is the state nut of Alabama, Arkansas, California, and Texas and is also the state tree of Texas. Name "Pecan" is from an Algonquin word, variously referring to pecans, walnuts, and hickory nuts. There are many pronunciations, some regional and others not.See " Pecan" at Wiktionary. The most common American pronunciation is . There is little agreement in the United States regarding the "correct" pronunciation, even regionally.

Hickory
Hickory is a common name for trees composing the genus ''Carya'', which includes around 18 species. Five or six species are native to China, Indochina, and India (Assam), as many as twelve are native to the United States, four are found in Mexico, and two to four are native to Canada. A number of hickory species are used for products like edible nuts or wood. Hickories are temperate forest trees with pinnately compound leaves and large nuts. Hickory flowers are small, yellow-green catkins produced in spring. They are wind-pollinated and self-incompatible. The fruit is a globose or oval nut, long and diameter, enclosed in a four- valved husk, which splits open at maturity. The nut shell is thick and bony in most species, and thin in a few, notably the pecan (''C. illinoinensis''); it is divided into two halves, which split apart when the seed germinates. Etymology The name "hickory" derives from a Native American word in an Algonquian language (perhaps Powhatan). It i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fagales
The Fagales are an order of flowering plants, including some of the best-known trees. The order name is derived from genus ''Fagus'', beeches. They belong among the rosid group of dicotyledons. The families and genera currently included are as follows: * Betulaceae – birch family (''Alnus'', '' Betula'', ''Carpinus'', ''Corylus'', '' Ostrya'', '' Ostryopsis'') *Casuarinaceae – she-oak family (''Allocasuarina'', ''Casuarina'', '' Ceuthostoma'', '' Gymnostoma'') *Fagaceae – beech family (''Castanea'', '' Castanopsis'', ''Chrysolepis'', '' Colombobalanus'', '' Fagus'', ''Lithocarpus'', '' Notholithocarpus'', ''Quercus'') * Juglandaceae – walnut family ('' Alfaroa'', '' Carya'', ''Cyclocarya'', ''Engelhardia'', ''Juglans'', '' Oreomunnea'', '' Platycarya'', '' Pterocarya'', '' Rhoiptelea'') *Myricaceae – bayberry family ('' Canacomyrica'', '' Comptonia'', ''Myrica'') * Nothofagaceae – southern beech family (''Nothofagus'') * Ticodendraceae – ticodendron family (''Tic ...

Rhoipteleoideae
''Rhoiptelea'' is a monotypic genus of flowering plants in the family Juglandaceae. It contains a single species, ''Rhoiptelea chiliantha'', commonly known as the horsetail tree. This genus was previously recognized in its own family, Rhoipteleaceae, but the APG III system of 2009 placed it in the Juglandaceae family. ''Rhoiptelea chiliantha'' is native to southwest China and north Vietnam and lives at the elevation of 700-1600m in mountainous areas. The trees are wind-pollinated, the flowers arranged in large sagged panicles usually 32 cm long like horse tails, and the fruit In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering.

Juglandoideae
Juglandoideae is a subfamily of the walnut family Juglandaceae. This clade was first described by Koidzumi in 1937 by the name "Drupoideae," based on the drupe-like fruits of ''Juglans'' and ''Carya''. This name was rejected because it was not based on the name of the type genus. Leroy (1955) and Melchior (1964) both published descriptions of the clade using the name "Jugandoideae," but both were deemed invalid due to technicalities. The first valid publication of the name was by Manning (1978). *Subfamily Juglandoideae **Tribe Caryeae ***''Carya'' – hickory and pecan ***''Annamocarya'' ***'' Platycarya'' **Tribe Juglandeae ***''Cyclocarya'' – wheel wingnut ***''Juglans'' – walnut ***''Pterocarya'' – wingnut Manos and Stone (2001) proposed the following reorganization to reflect a more probable phylogenetic relationship that shows that ''Platycarya'' is sister to the rest of the subfamily, while Manchester (1987) addressed the fossil record of ...

Alfaroa
''Alfaroa'' is a genus of evergreen trees in the Juglandaceae family of the Fagales, growing in montane and submontane tropical rain forests in Central America. The wood is characterized by solid pith, pink heartwood, and vessels with scalariform perforations, as well as simple perforations. Description The (usually pinnately compound) leaves are evergreen and lack stipules. They are alternate, rarely opposite. The plants are monoecious, the male flowers being in lateral panicles (several pairs of catkins on an inflorescence) and the female flowers born terminally either in a single spike or in a hermaphroditic panicle including several paired male catkins. Each flower has a wide bract, two bracteoles, and four sepals. The flowers are sessile. The male flowers have a round or oblong receptacle and six to ten stamens. The pollen grains are approximately 24 micrometers in diameter and are slightly triangular in polar view. The small fruits are nuts, one-chambered at the apex ...
