Pyrus × Phaeocarpa
''Pyrus phaeocarpa'', the dusky pear or orange pear, is a species of flowering plant in the family Rosaceae, native to the Loess Plateau of northern China. A wide tree reaching at most in height, it is hardy to USDA zone 5, or perhaps even zone 4. Its small yellow to brown fruit are edible, and its Autumn foliage is bright orange to orange-red, giving it good potential as an ornamental. Its chloroplast genome shows that it is closely related to ''Pyrus pashia ''Pyrus pashia'', the wild Himalayan pear, is a small to medium size deciduous tree of the small and oval shaped crown with ovate, finely toothed leaves, attractive white flowers with red anthers and small pear-like fruits.

Alfred Rehder
Alfred Rehder (4 September 1863 in Waldenburg, Saxony – 25 July 1949 in Jamaica Plain, Massachusetts) was a German-American botanical taxonomist and dendrologist who worked at the Arnold Arboretum of Harvard University. He is generally regarded as the foremost dendrologist of his generation. Life Georg Alfred Rehder was born in the castle of Waldenburg to Thekla née Schmidt (1839–1897) and Paul Julius Rehder (1833–1917), the superintendent of parks and gardens of the principality of Schönburg-Waldenburg. Through his father, Rehder was introduced to the gardening profession. On his mother's side of the family, Rehder was likely descended from Henry, Duke of Anhalt-Köthen (1778–1847). Rehder broke off his attendance at the gymnasium in Zwickau in 1881 and did not pursue university studies, instead working for three years as an apprentice under the tutelage of his father. His professional career began in 1884 at the Berlin Botanical Garden. Here he was able t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosaceae
Rosaceae (), the rose family, is a family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus '' Rosa''. The family includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere. Many economically important products come from the Rosaceae, including various edible fruits, such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, blackberries, loquats, strawberries, rose hips, hawthorns, and almonds. The family also includes popular ornamental trees and shrubs, such as roses, meadowsweets, rowans, firethorns, and photinias.

Loess Plateau
The Loess Plateau is a plateau in north-central China formed of loess, a clastic rock, clastic silt-like sediment formed by the accumulation of Dust#Atmospheric, wind-blown dust. It is located southeast of the Gobi Desert and is surrounded by the Yellow River. It includes parts of the Chinese provinces of Qinghai, Gansu, Shaanxi and Shanxi. The depositional setting of the Chinese Loess Plateau was shaped by the tectonic movement in the Neogene period, after which strong southeast winds caused by the East Asian Monsoon transported sediment to the plateau during the Quaternary period. The three main morphological types in the Loess Plateau are loess platforms, ridges and hills, formed by the deposition and erosion of loess. Most of the loess comes from the Gobi Desert and other nearby deserts. The sediments were transported to the Loess Plateau during interglacial periods by southeasterly prevailing winds and winter monsoon winds. After the deposition of sediments on the plateau, t ...

Hardiness Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. A plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of . Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. However, some confusion can exist in discussing buildings and HVAC, where "climate zone" can refer to the International Energy Conservation Code zones, where Zone 1 is warm and Zone 8 is cold. Other hardiness rating schemes have been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pyrus Betulifolia
''Pyrus betulifolia'', known as the birchleaf pear in English and tang li in Chinese, is a deciduous wild pear tree native to the leafy forests of northern and central China and Tibet. It can grow 10 meters high in optimal conditions. Formidable thorns (which are modified stems) protect its leaves from predation. These narrow and extended leaves, resembling smaller birch leaves, provide it with its specific name ''betulifolia'', meaning "birch leaf". Its small fruit ( in diameter) are used as ingredients in types of rice wine in China and sake in Japan. It is used as rootstock for grafting Grafting or graftage is a horticulture, horticultural technique whereby tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion () while the lower part is called the roots ... popular Asian pear varieties.

Pyrus Ussuriensis
''Pyrus ussuriensis'', also known as the Ussurian pear, Harbin pear, and Manchurian pear, is a species of flowering plant in the family Rosaceae. It is native to Korea, Japan, China, and the Ussuri River area of far eastern Russia. It has flowers in spring that are slightly pink when budding and then turn white. Buds are dark brown and have an alternating arrangement. The tree grows to a height of about and prefers well-drained loam-type soils. It is considered the hardiest of all pears. When planted in milder climates, the trees have been known to be killed by freezes after they begin budding. Many species of birds and mammals feed upon the fruit of this species. Deer, mice, and rabbits are known to damage the trees. Leaves are dark green in spring and summer and turn dark red and gold in autumn. Products made from the fruits may prove more effective than commercial insecticides in killing ticks and mites. The fruits are not the tastiest of pears to humans, but the taste is ...

Pyrus
Pears are fruits produced and consumed around the world, growing on a tree and harvested in late summer into mid-autumn. The pear tree and shrub are a species of genus ''Pyrus'' , in the family Rosaceae, bearing the pomaceous fruit of the same name. Several species of pears are valued for their edible fruit and juices, while others are cultivated as trees. The tree is medium-sized and native to coastal and mildly temperate regions of Europe, North Africa, and Asia. Pear wood is one of the preferred materials in the manufacture of high-quality woodwind instruments and furniture. About 3,000 known varieties of pears are grown worldwide, which vary in both shape and taste. The fruit is consumed fresh, canned, as juice, dried, or fermented as perry. Etymology The word ''pear'' is probably from Germanic ''pera'' as a loanword of Vulgar Latin ''pira'', the plural of ''pirum'', akin to Greek ''apios'' (from Mycenaean ''ápisos''), of Semitic origin (''pirâ''), meaning "fruit" ...

Trees Of China
In botany, a tree is a perennial plant with an elongated Plant stem, stem, or trunk (botany), trunk, usually supporting Branch, branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only Bark (botany), woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller Arecaceae, palms, Cyatheales, tree ferns, Musa (genus), bananas, and bamboos. Trees are not a Monophyletic group, monophyletic taxonomic group but consist of a wide variety of plant species that Convergent evolution, have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of China
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are Indigenous (ecology), indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a la ...

Flora Of Xinjiang
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was ...
