Cornus Wilsoniana
''Cornus wilsoniana'', called ghost dogwood or Wilson's dogwood, is species of ''Cornus'' native to central and southeastern China. A tree typically 5 to 10m, rarely reaching 40m, it has leaves with white undersides, profuse white flowers in May, and striking grey–green mottled bark on mature specimens. The purplishblack fruit are harvested for vegetable oil, the leaves are used for fodder, and the timber is valued for tools and furniture. Its well-shaped crown and attractive bark has led to proposals that it be developed as a street tree.

Walther Wangerin
Walther Wangerin (15 April 1884, in Giebichenstein, Halle an der Saale – 19 April 1938, in Langfuhr, Danzig-Langfuhr) was a German botanist. He studied mathematics and natural sciences at the University of Halle, receiving his doctorate in 1906. Following graduation, he worked as an assistant to Adolf Engler at the Berlin-Dahlem Botanical Garden and Botanical Museum, botanical garden in Berlin-Dahlem. In 1909 he became a schoolteacher in Burg bei Magdeburg, and from 1913 taught classes at the Gdańsk University of Technology, technical school in Danzig. In 1920 he was appointed divisional director at the Danzig Museum of Natural History and Prehistory.BHL Taxonomic literature : a selective guide to botanical publications He made contributions regarding the plant families Alangiaceae, Cornaceae, Garryaceae and Nyssaceae in E ...

Cornus
''Cornus'' is a genus of about 30–60 species of woody plants in the family Cornaceae, commonly known as dogwoods, which can generally be distinguished by their blossoms, berries, and distinctive bark. Most are deciduous trees or shrubs, but a few species are nearly herbaceous perennial subshrubs, and some species are evergreen. Several species have small heads of inconspicuous flowers surrounded by an involucre of large, typically white petal-like bracts, while others have more open clusters of petal-bearing flowers. The various species of dogwood are native throughout much of temperate and boreal Eurasia and North America, with China, Japan, and the southeastern United States being particularly rich in native species. Species include the common dogwood ''Cornus sanguinea'' of Eurasia, the widely cultivated flowering dogwood ''(Cornus florida)'' of eastern North America, the Pacific dogwood ''Cornus nuttallii'' of western North America, the Kousa dogwood ''Cornus kous ...

Trees Of China
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 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
