Curly Birch
Curly birch (''Betula pendula'' var. ''carelica'') is a Variety (botany), variant of the plant species Betula pendula, silver birch (also known as warty birch, European white birch, or East Asian white birch) with a genetic defect that causes the tree to twist on the stem with curls. The annual rings are oriented incorrectly, which gives the wood a fiery appearance. The variant originally comes from Karelia in Finland and Russia. The curliness is passed on in up to 70% of all trees in the next generation. Common spring birch is also sometimes referred to as masonry birch, but one should only use that term for trees that have the real curliness. The wood The annual rings are wavelike and irregular, with brown curly-grained wood tissue cells often exhibiting a V pattern in the cross-sectional view. If this pattern continues evenly across the entire surface, the result is a starlike pattern (a.k.a. curly-grain blossom). The longitudinal section of the stem exhibits lenslike patte ...

Pen And Letter Opener
A pen is a common writing instrument that applies ink to a surface, usually paper, for writing or drawing. Early pens such as reed pens, quill pens, dip pens and ruling pens held a small amount of ink on a nib or in a small void or cavity which had to be periodically recharged by dipping the tip of the pen into an inkwell. Today, such pens find only a small number of specialized uses, such as in illustration and calligraphy. Reed pens, quill pens and dip pens, which were used for writing, have been replaced by ballpoint pens, rollerball pens, fountain pens and felt or ceramic tip pens. Ruling pens, which were used for technical drawing and cartography, have been replaced by technical pens such as the Rapidograph. All of these modern pens contain internal ink reservoirs, such that they do not need to be dipped in ink while writing. Types Modern Pens commonly used today can be categorized based on the mechanism of the writing tip and the type of ink: * A ballpoint pen dispens ...

Betula Pendula
''Betula pendula'', commonly known as silver birch, warty birch, European white birch, or East Asian white birch, is a species of tree in the family Betulaceae, native to Europe and parts of Asia, though in southern Europe, it is only found at higher altitudes. Its range extends into Siberia, China, and southwest Asia in the mountains of northern Turkey, the Caucasus, and northern Iran. It has been introduced into North America, where it is known as the European white birch or weeping birch and is considered invasive in some states in the United States and parts of Canada. The tree can also be found in more temperate regions of Australia. The silver birch is a medium-sized deciduous tree that owes its common name to the white peeling bark on the trunk. The twigs are slender and often pendulous and the leaves are roughly triangular with doubly serrate margins and turn yellow and brown in autumn before they fall. The flowers are catkins and the light, winged seeds get widely sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variety (botany)
In botanical nomenclature, variety (abbreviated var.; in la, varietas) is a taxonomic rank below that of species and subspecies, but above that of form. As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species. Example The pincushion cactus, ''Escobaria vivipara'' (Nutt.) Buxb., is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about . Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety ''Escobaria vivipara'' var. ''arizonica'' is from Arizona, while ''Escobaria vivipara'' var. ''neo-mexicana'' is from New Mexico. See also '' Capsicum annuum var. glabriusculum'' Definitions The term is defined in different ways by different authors. However, the I ...

Karelia
Karelia ( Karelian and fi, Karjala, ; rus, Каре́лия, links=y, r=Karélija, p=kɐˈrʲelʲɪjə, historically ''Korjela''; sv, Karelen), the land of the Karelian people, is an area in Northern Europe of historical significance for Russia (including the Soviet era), Finland, and Sweden. It is currently divided between northwestern Russia (specifically the federal subjects of the Republic of Karelia and Leningrad Oblast) and Finland (the regions of South Karelia, North Karelia, and the eastern portion of modern-day Kymenlaakso). Use of name Various subdivisions may be called Karelia. Finnish Karelia was a historical province of Finland, and is now divided between Finland and Russia, often called just ''Karjala'' in Finnish. The eastern part of this chiefly Lutheran area was ceded to Russia after the Winter War of 1939–40. The Republic of Karelia is a Russian federal subject, including East Karelia with a chiefly Russian Orthodox population. Within present-da ...

Ingria
Ingria is a historical region in what is now northwestern European Russia. It lies along the southeastern shore of the Gulf of Finland, bordered by Lake Ladoga on the Karelian Isthmus in the north and by the River Narva on the border with Estonia in the west. The earliest known indigenous European peoples of the region are the now mostly Eastern Orthodox Izhorians and Votians, as well as the Ingrian Finns who descend from the Lutheran Finnish immigrants who settled in the area in the 17th century, when Finland proper and Ingria were both parts of the Swedish Empire. Ingria as a whole never formed a separate state, however North Ingria was an independent state for just under two years in 1919–1920. The Ingrians, understood as the inhabitants of Ingria regardless of ethnicity, can hardly be said to have been a nation, although the Soviet Union recognized their "nationality"; as an ethnic group, the Ingrians proper, Izhorians, are close to extinction together with their langua ...

Wood
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the productio ...
