Rowan
The rowans ( or ) or mountain-ashes are shrubs or trees in the genus ''Sorbus'' of the rose family, Rosaceae. They are native throughout the cool temperate regions of the Northern Hemisphere, with the highest species diversity in the Himalaya, southern Tibet and parts of western China, where numerous apomictic microspecies occur.Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins . The name ''rowan'' was originally applied to the species ''Sorbus aucuparia'' and is also used for other species in ''Sorbus'' subgenus ''Sorbus''. Formerly, when a wider variety of fruits were commonly eaten in Europe and North America, ''Sorbus'' was a domestically used fruit throughout these regions. It is still used in some countries, but '' S. domestica'', for example, has largely vanished from Britain, where it was traditionally appreciated. Natural hybrids, often including ''S. aucuparia'' and the whitebeam, ''Sorbus aria'', give rise to many endemic variants in the UK. ...

Sorbus Aucuparia
''Sorbus aucuparia'', commonly called rowan (UK: /ˈrəʊən/, US: /ˈroʊən/) and mountain-ash, is a species of deciduous tree or shrub in the rose family. It is a highly variable species, and botanists have used different Circumscription (taxonomy), definitions of the species to include or exclude trees native to certain areas; a recent definition includes trees native to most of Europe and parts of Asia, as well as northern Africa. The range extends from Madeira, the British Isles and Iceland to Russia and northern China. Unlike many plants with similar distributions, it is not native to Japan. The tree has a slender trunk with smooth bark, a loose and roundish crown, and its leaves are pinnate in pairs of leaflets on a central vein with a terminal leaflet. It blossoms from May to June in dense corymbs of small yellowish white flowers and develops small red pomes as fruit that ripen from August to October and are eaten by many bird species. The plant is undemanding and frost h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sorbus
''Sorbus'' is a genus of over 100 species of trees and shrubs in the rose family, Rosaceae. Species of ''Sorbus'' (''s.l.'') are commonly known as whitebeam, rowan (mountain-ash) and service tree. The exact number of species is disputed depending on the circumscription of the genus, and also due to the number of apomictic microspecies, which some treat as distinct species, but others group in a smaller number of variable species.

Bríatharogam
In Early Irish literature a ''Bríatharogam'' ("word ogham", plural ''Bríatharogaim'') is a two word kenning which explains the meanings of the names of the letters of the Ogham alphabet. Three variant lists of ''bríatharogaim'' or 'word-oghams' have been preserved, dating to the Old Irish period. They are as follows: *''Bríatharogam Morainn mac Moín'' *''Bríatharogam Maic ind Óc'' *''Bríatharogam Con Culainn'' The first two of these are attested from all three surviving copies of the ''Ogam Tract'', while the "Cú Chulainn" version is not in the Book of Ballymote and only known from 16th- and 17th-century manuscripts. The '' Auraicept na n-Éces'' or 'Scholars' Primer' reports and interprets the ''Bríatharogam Morainn mac Moín''. Later Medieval scholars believed that all of the letter names were those of trees, and attempted to explain the ''bríatharogaim'' in that light. However, modern scholarship has shown that only eight at most of the letter names are those of tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apomictic
In botany, apomixis is asexual reproduction without fertilization. Its etymology is Greek for "away from" + "mixing". This definition notably does not mention meiosis. Thus "normal asexual reproduction" of plants, such as propagation from cuttings or leaves, has never been considered to be apomixis, but replacement of the seed by a plantlet or replacement of the flower by bulbils were categorized as types of apomixis. Apomictically produced offspring are genetically identical to the parent plant. Some authors included all forms of asexual reproduction within apomixis, but that generalization of the term has since died out. In flowering plants, the term "apomixis" is commonly used in a restricted sense to mean agamospermy, i.e., clonal reproduction through seeds. Although agamospermy could theoretically occur in gymnosperms, it appears to be absent in that group. Apogamy is a related term that has had various meanings over time. In plants with independent gametophytes (notab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sorbus Torminalis
''Sorbus torminalis'', with common names wild service tree, chequers, and checker tree, is a species of tree in the mountain ash or rowan genus (''Sorbus'') of the rose family (Rosaceae), that is native to Europe, parts of northern Africa and western Asia. Description It is a medium-sized deciduous tree growing to tall, with a trunk up to in diameter. The bark is smooth and grayish, but flaky, peeling away in squarish plates to reveal darker brown layers. The leaves are long and broad with a petiole, dark green on both sides, with five to nine acute lobes; the basal pair of lobes are spreading, the rest more forward-pointing and decreasing in size to the leaf apex, and with finely toothed margins; the undersides have small hairs when young, but both sides are smooth and shiny when older; the autumn colour is yellow to red-brown. The flowers are in diameter, with five white petals and 20 creamy-white stamens; they are produced in corymbs diameter in late spring to early summ ...

Sorbus Domestica
''Sorbus domestica'', with the common name service tree or sorb tree (because of its fruit), is a species of ''Sorbus'' native to western, central and southern Europe, northwest Africa (Atlas Mountains), and southwest Asia (east to the Caucasus).Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins .Mitchell, A. F. (1974). ''A Field Guide to the Trees of Britain and Northern Europe'', p 280. Collins Hampton, M., & Kay, Q. O. N. (1995).

Rosaceae
Rosaceae (), the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus ''Rosa''. Among the most species-rich genera are '' Alchemilla'' (270), '' Sorbus'' (260), '' Crataegus'' (260), '' Cotoneaster'' (260), '' Rubus'' (250), and '' Prunus'' (200), which contains the plums, cherries, peaches, apricots, and almonds. However, all of these numbers should be seen as estimates—much taxonomic work remains. The family Rosaceae includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere. Many economically important products come from the Rosaceae, including various edible fruits, such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, blackberries, loquats, strawberries, rose hips, hawthorns, and almonds. The family also includes popular ornamental trees and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamamelis
Witch-hazels or witch hazels (''Hamamelis'') are a genus of flowering plants in the family Hamamelidaceae, with three species in North America ('' H. ovalis'', '' H. virginiana'', and '' H. vernalis''), and one each in Japan ('' H. japonica'') and China ('' H. mollis''). The North American species are occasionally called winterbloom. Growth The witch-hazels are deciduous shrubs or (rarely) small trees growing to 3 to 7.5 m tall, even more rarely to 12 m tall. The leaves are alternately arranged, oval, 5 to 15 cm long, and 2.5 to 10 cm wide, with a smooth or wavy margin. The genus name, ''Hamamelis'', means "together with fruit", referring to the simultaneous occurrence of flowers with the maturing fruit from the previous year. ''H. virginiana'' blooms in September–November while the other species bloom from January–March. Each flower has four slender strap-shaped petals 1 to 2 cm long, pale to dark yellow, orange, or red. The fruit is a two-part capsu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Welsh Language
Welsh ( or ) is a Celtic language of the Brittonic subgroup that is native to the Welsh people. Welsh is spoken natively in Wales, by some in England, and in Y Wladfa (the Welsh colony in Chubut Province, Argentina). Historically, it has also been known in English as "British", "Cambrian", "Cambric" and "Cymric". The Welsh Language (Wales) Measure 2011 gave the Welsh language official status in Wales. Both the Welsh and English languages are ''de jure'' official languages of the Welsh Parliament, the Senedd. According to the 2021 census, the Welsh-speaking population of Wales aged three or older was 17.8% (538,300 people) and nearly three quarters of the population in Wales said they had no Welsh language skills. Other estimates suggest that 29.7% (899,500) of people aged three or older in Wales could speak Welsh in June 2022. Almost half of all Welsh speakers consider themselves fluent Welsh speakers and 21 per cent are able to speak a fair amount of Welsh. The Welsh ...

Scots Language
Scots (endonym: ''Scots''; gd, Albais, ) is an Anglic language, Anglic Variety (linguistics), language variety in the West Germanic language, West Germanic language family, spoken in Scotland and parts of Ulster in the north of Ireland (where the local dialect is known as Ulster Scots dialect, Ulster Scots). Most commonly spoken in the Scottish Lowlands, Northern Isles and northern Ulster, it is sometimes called Lowland Scots or Broad Scots to distinguish it from Scottish Gaelic, the Goidelic languages, Goidelic Celtic language that was historically restricted to most of the Scottish Highlands, the Hebrides and Galloway after the 16th century. Modern Scots is a sister language of Modern English, as the two diverged independently from the same source: Early Middle English (1150–1300). Scots is recognised as an indigenous language of Scotland, a regional or minority language of Europe, as well as a vulnerable language by UNESCO. In the 2011 United Kingdom census, 2011 Scottis ...
