An oak is a hardwood tree or shrub in the genus Quercus of the beech family. They have spirally arranged leaves, often with lobed edges, and a nut called an acorn, borne in a cup. The genus is widely distributed in the Northern Hemisphere; it includes some 500 species, both deciduous and evergreen. Fossil oaks date back to the Middle Eocene. Molecular phylogeny shows that the genus is divided into Old World and New World clades, but many oak species hybridise freely, making the genus's history difficult to resolve.
Quercus acutissima, the sawtooth oak, is an Asian species of oak native to China, Tibet, Korea, Japan, Indochina and the Himalayas. It is widely planted in many lands and has become naturalized in parts of North America.
Quercus dentata, also called Japanese emperor oak or daimyo oak is a species of oak native to East Asia. The name of the tree is often translated as "sweet oak" in English to distinguish it from Western varieties. It is placed in section Quercus.
Quercus variabilis, the Chinese cork oak, is a species of oak in the section Quercus sect. Cerris, native to a wide area of eastern Asia in southern, central, and eastern China, Taiwan, Japan, and Korea.
Liuixalus hainanus is a species of frog in the family Rhacophoridae. It is endemic to Hainan Island, China, and only known from its type locality, Mount Diaoluo in Lingshui Li Autonomous County.
The Hainan black-crested gibbon or Hainan gibbon, is a Critically Endangered species of gibbon found only on Hainan Island, China. It was formerly considered a subspecies of the eastern black crested gibbon from Hòa Bình and Cao Bằng provinces of Vietnam and Jingxi County in Guangxi Zhuang Autonomous Region, China. Molecular data, together with morphology and call differences, suggest it is a separate species. Its habitat consists of broad-leaved forests and semi-deciduous monsoon forests. It feeds on ripe, sugar-rich fruit, such as figs and, at times, leaves, and insects.
Cinnamomum parthenoxylon is an evergreen tree in the genus Cinnamomum, 10–20 m (33–66 ft) tall. It is native to South and East Asia.
The flora of China consists of a diverse range of plant species including over 39,000 vascular plants, 27,000 species of fungi and 3000 species of bryophytes. More than 30,000 plant species are native to China, representing nearly one-eighth of the world's total plant species, including thousands found nowhere else on Earth. China's land, extending over 9.6 million km, contains a variety of ecosystems and climates for plants to grow in. Some of the main climates include shores, tropical and subtropical forests, deserts, elevated plateaus and mountains. The events of the continental drift and early Paleozoic Caledonian movement also play a part in creating climatic and geographical diversity resulting in high levels of endemic vascular flora. These landscapes provide different ecosystems and climates for plants to grow in, creating a wide variety of different flora spanning over not just China, but different parts of the world.
Quercus asymmetrica is an oak tree species in the beech family Fagaceae. It is found in China and northern Vietnam. It is placed in subgenus Cerris, section Cyclobalanopsis.
Quercus franchetii, commonly known as the zhui lian li evergreen oak, is a species of oak in the Ilex section of the genus, native to a wide area of eastern Asia. It is an oak native to China, northern Thailand and Vietnam, growing at altitudes between 800 and 2,600 metres.
Quercus semecarpifolia is an Asian species of oak. It is native to the Himalayas and nearby mountains in Tibet, Afghanistan, India, Nepal, and Pakistan, where it is referred to as kharsu. It is classified in subgenus Cerris, section Ilex.
Quercus bella is an uncommon species of oak tree. It is native to Guangdong, Guangxi, Yunnan, and Hainan provinces of southern China and to northern Vietnam. It is placed in subgenus Cerris, section Cyclobalanopsis.
Quercus poilanei is an Asian species of tree in the family Fagaceae. It has been found in northern Indochina and also in the Province of Guangxi in southern China. It is placed in subgenus Cerris, section Cyclobalanopsis.
Quercus xanthotricha is an Asian species of tree in the beech family Fagaceae. It has been found in northern Indochina and in southern China (Yunnan). It is placed in subgenus Cerris, section Cyclobalanopsis.
The Skywalker hoolock gibbon or Gaoligong hoolock gibbon is an arboreal primate in the gibbon family, Hylobatidae. It is one of three species of hoolock gibbon and was first described in January 2017 in the American Journal of Primatology. The Skywalker hoolock gibbon is one of two species of Eastern hoolocks: H. tianxing and H. leuconedys. Researchers estimate H. tianxing diverged from H. leuconedys roughly 490,000 years ago. The Eastern hoolock is vulnerable on the IUCN Red List, with a population of 310,000–370,000 individuals. Of this population, H. tianxing makes up less than 150 individuals, making the Skywalker hoolock gibbon an endangered species.
Quercus arbutifolia, synonym Quercus obovatifolia, is a species of oak in the beech family Fagaceae, native to southeast China and Vietnam. It is placed in Quercus sect. Cyclobalanopsis, the ring-cupped oaks. There are no known subspecies.
Quercus aquifolioides is a species of oak native to south-central China and Tibet. It is in the subgenus Cerris, section Ilex. It is a shrub or small tree adapted to high elevations.
Quercus spinosa is a species of oak native to central China, Taiwan and Myanmar, in the subgenus Cerris, section Ilex. An evergreen tree, its leaf traits may be adaptations to altitude. It is placed in section Ilex.
Quercus tarokoensis is a species of oak. It is a tree endemic to eastern Taiwan. It grows on calcareous (limestone-derived) soils in evergreen forests, often on steep slopes, from 400 to 1,300 meters elevation.
