Quercus glauca is a ( scientific name : Cyclobalanopsis ) is FAGACEAE one genus , also known as C. glauca genus or Cyclobalanopsis, 150 Zhong .
In plant taxonomy, it is often used in combination with Quercus ( or Quercus ) or with paralysed genus, but in terms of characteristics, the biggest difference between the two is that the green genus is mostly an evergreen tree . Most of the genera are deciduous trees. If they are based on the distribution of ethnic groups, they are mainly distributed in the tropical and subtropical regions of Asia, whereas the paralyzed species are mainly distributed in the temperate regions of Europe and North America in the northern hemisphere . Therefore, they are in China and Taiwan. Most of the plant taxonomy community has isolated the genus Spodoptera as a species [1] [2] .

Features and uses [ edit ]
Evergreen trees, thin shrubs , tree heights between 10 and 40 meters , bark usually smooth, leaves spiral alternate, leaf margin usually serrate, pinnate veins , male and female plants, male flower twilight like willow drooping branches the catkins ; female often scattered or clustered scenes, when the mature fruit, cupule called as outer involucre, usually containing a nut, or the following year to year mature mature, nearly oval shape is circular, The top has a protuberance with proton leaves and is rich in starch. The cotyledons do not emerge when germinated .
The genus wood is radiant hole material. The common wood color is reddish-brown, yellow-brown or gray white. The wood has high density and hard texture. It can be used as building beam, tool handle, railway sleeper and other materials. The bark is rich in tannins and can be refined. As a fur or dye , another nut is rich in starch and can be used for feed, wine, etc. [2] .
Distribution evolution [ edit ]
Modern distribution center of the genus Quercus glauca located in the Indian subcontinent and Indochina Peninsula in northern, as well as China , Yunnan , Guangxi , Guangdong, Southwest and other places. And thus spread to the surrounding, south to Indonesia, Sumatra , Java Island , Jialimandan and Bali , and do not cross the Wallace Line ; east to reach Taiwan, the Korean Peninsula , Japan Honshu north latitude and 36 degrees region; north to Liaoning , Fushun area; westward along the then ancient Mediterranean coast during the Oligocene spread to Europe .
In the late Pliocene , as the global temperature dropped, the overall climatic zone moved southwards, causing tropical plants to move southwards. The north boundary of the subtropical evergreen broad-leaved forest retreated from the Qinling and Huaihe rivers to the present day ; plus the Indian and Eurasian plates. the collision, the disappearance of the ancient Mediterranean, the coastal climate becomes drier, but also Quercus glauca is a reason to return sub-sector Boosey Asia [3] .
Classification [ edit ]
