Pinus Fenzeliana
''Pinus fenzeliana'' commonly known as the Hainan white pine or Fenzel's pine, is a tree endemic to the island of Hainan off southern China. This pine reaches heights of 20 m with a trunk 1 m in diameter. Description The leaves are needle-like, in fascicles of five, and 5–13 cm long. The seed cones are 6–11 cm long, with thick, woody scales; the seeds are large, about 8–15 mm long, with a vestigial 3 mm wing, similar to the related Chinese white pine (''Pinus armandii''). Hainan white pine differs from that species in the shorter needles, smaller cones, and in being adapted to a subtropical rainforest habitat. A pine from the Dabie Mountains in Anhui, eastern China, first described as a species ''Pinus dabeshanensis'', is occasionally treated as a variety of this species, but more commonly as a variety of ''P. armandii'', which it more closely resembles. Reports of ''Pinus fenzeliana'' from Vietnam have not been verified; trees in this area have proved ...

Hand
A hand is a prehensile, multi-fingered appendage located at the end of the forearm or forelimb of primates such as humans, chimpanzees, monkeys, and lemurs. A few other vertebrates such as the koala (which has two opposable thumbs on each "hand" and fingerprints extremely similar to human fingerprints) are often described as having "hands" instead of paws on their front limbs. The raccoon is usually described as having "hands" though opposable thumbs are lacking. Some evolutionary anatomists use the term ''hand'' to refer to the appendage of digits on the forelimb more generally—for example, in the context of whether the three digits of the bird hand involved the same homologous loss of two digits as in the dinosaur hand. The human hand usually has five digits: four fingers plus one thumb; these are often referred to collectively as five fingers, however, whereby the thumb is included as one of the fingers. It has 27 bones, not including the sesamoid bone, the number o ...

Dabie Mountains
The Dabie Mountains () are a major mountain range located in central China. Running northwest-to-southeast, they form the main watershed between the Huai and Yangtze rivers. The range also marks the boundary between Hubei Province and its neighbors of Henan (to the north) and Anhui (to the east). The western part of Dabie Mountains has a low elevation of only 1,000–1,300 feet (300–400 meters), though there are a few peaks rising to 3,000 feet (900 meters). The eastern part is higher, averaging more than 3,300 feet (1,000 meters). The highest peak is Mount Tianzhu at 5,820 feet (1,774 meters), with several others topping 5,000 feet (1,500 meters) including the high Tiantangzhai. Landscape The range is heavily forested (about 85% coverage) and yields valuable bamboo as well as oak, particularly cork oak, making it China's chief cork-producing area. The region is median income, and subsistence agriculture is the heart of its economy with rice and tea predominating. The main t ...

Flora Of Hainan
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. 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 first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phyt ...

Endemic Flora Of China
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ...

Pinus
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or trinomials) recognized by the ACS. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine located in southern Oregon's Rogue Riv ...

Guangdong White Pine
''Pinus wangii'', commonly known as the Guangdong white pine (), is a species of conifer in the family Pinaceae. It was named after Dr. Shao-Ping Wang, a professor of forest genetics. Distribution This pine tree is native to Yunnan Province of southern China, where two populations are known from Wenshan Prefecture. It is uncertain whether it occurs in northern Vietnam. ''Pinus wangii'' is an IUCN Red List Endangered species, threatened by continued logging Logging is the process of cutting, processing, and moving trees to a location for transport.

Pinus Dabeshanensis
''Pinus dabeshanensis'', Dabieshan white pine, is a species of pine found only in China. Some sources consider it as a synonym of Chinese white pine (''Pinus armandii''), which it closely resembles.

Rainforest
Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described. Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the " world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. Definition Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of lea ...

Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that 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 reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically ...
