Sessile Oak
''Quercus petraea'', commonly known as the sessile oak, Welsh oak, Cornish oak, Irish oak or durmast oak, is a species of oak tree native to most of Europe and into Anatolia and Iran. The sessile oak is the national tree of Ireland, and an unofficial emblem in Wales and Cornwall. Description The sessile oak is a large deciduous tree up to tall, in the white oak section of the genus (''Quercus'' sect. ''Quercus'') and similar to the pedunculate oak (''Q. robur''), with which it overlaps extensively in range. The leaves are long and broad, evenly lobed with five to six lobes on each side and a petiole. The male flowers are grouped into catkins, produced in the spring. The fruit is an acorn long and broad, which matures in about six months.

Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the Plant stem, stem. It is able to twist the leaf to face the sun, producing a characteristic foliage arrangement (spacing of blades), and also optimizing its exposure to sunlight. Outgrowths appearing on each side of the petiole in some species are called stipules. The terms wikt:petiolate, petiolate and wikt:apetiolate, apetiolate are applied respectively to leaves with and without petioles. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves the leaf stalk may be long (as in the leaves of celery and rhubarb), or short (for example basil). When completely absent, the blade attaches directly to the stem and is said to be Sessility (botany), sessile or apetiolate. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile.

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English Natural history#Before 1900, naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a Common descent, common ancestor is now generally accepted and considered a fundamental scientific concept. In a joint presentation with Alfred Russel Wallace, he introduced his scientific theory that this Phylogenetics, branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.. Darwin has been described as one of the most influential figures in human history and was honoured by Burials and memorials in Westminster Abbey, burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh Medical Schoo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus × Rosacea
''Quercus'' × ''rosacea'', the hybrid oak, is a naturally occurring hybrid species of oak native to central and northern Europe. It is a hybrid between sessile oak ''Quercus petraea'', and pedunculate oak ''Quercus robur'', found where their ranges overlap. As a fertile hybrid, it is morphologically variable, but in general the traits are intermediate between those of the parents. A thin section of a ''Q.''×''rosacea'' specimen was used by artist-in-residence Tania Kovats to create a monumental work called TREE for the ceiling of the Mezzanine of the Natural History Museum, London in celebration of the bicentennial of Charles Darwin's birth. References {{DEFAULTSORT:Quercus × rosacea rosacea Rosacea is a long-term skin condition that typically affects the face.

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Botanical Name
A botanical name is a formal scientific name conforming to the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or cultivar group, Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, Fungus, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), Chytridiomycota, chytrids, oomycetes, slime moulds and Photosynthesis, photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated variou ...

Botany
Botany, also called plant science, is the branch of natural science and biology studying plants, especially Plant anatomy, their anatomy, Plant taxonomy, taxonomy, and Plant ecology, ecology. A botanist or plant scientist is a scientist who specialises in this field. "Plant" and "botany" may be defined more narrowly to include only land plants and their study, which is also known as phytology. Phytologists or botanists (in the strict sense) study approximately 410,000 species of Embryophyte, land plants, including some 391,000 species of vascular plants (of which approximately 369,000 are flowering plants) and approximately 20,000 bryophytes. Botany originated as history of herbalism#Prehistory, prehistoric herbalism to identify and later cultivate plants that were edible, poisonous, and medicinal, making it one of the first endeavours of human investigation. Medieval physic gardens, often attached to Monastery, monasteries, contained plants possibly having medicinal benefit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inosculation
Inosculation is a natural phenomenon in which trunks, branches or roots of two trees grow together in a manner biologically similar to the artificial process of grafting. The term is derived from the Latin roots ''in'' + '' ōsculārī'', "to kiss into/inward/against" or etymologically and more illustratively "to make a small mouth inward/into/against"; trees having undergone the process are referred to in forestry as gemels, from the Latin word meaning "a pair". It is most common for branches of two trees of the same species to grow together, though inosculation may be noted across related species. The branches first grow separately in proximity to each other until they touch. At this point, the bark on the touching surfaces is gradually abraded away as the trees move in the wind. Once the cambium of two trees touches, they sometimes self-graft and grow together as they expand in diameter. Inosculation customarily results when tree limbs are braided or pleached.

Divljana
Divljana () is a village in the municipality of Bela Palanka, Serbia. According to the 2002 census, the village has a population of 141 people.Popis stanovništva, domaćinstava i Stanova 2002.

''Zapis'' oak There is a large old oak tree in Divljana that is a ''zapis'' ("inscription"), a village tree considered sacred. In a custom originating in pre-Christian Slavic mythology, a large tree, usually an oak, would have a cross carved into its bark, and would serve as a temple. Oak trees were sanctified in the settlements which had no church of their own.

Zapis
A ''zapis'' ( sr-Cyrl, запис, , literally "inscription"; plural: ''zapisi'' (записи)) is a sacred tree in Serbian Orthodox tradition, protecting the village within whose bounds it is situated. A cross is inscribed into the bark of each ''zapis''. Most of these trees are large oaks. Prayers are offered to God under the crown of the ''zapis'', where church services may also be held, especially during village festivals observed to supplicate God for protection against destructive weather conditions. In settlements without a church, ceremonies such as weddings and baptisms were once conducted under the tree. Folk tradition maintains that great misfortune will befall anyone that dares fell a ''zapis''. According to Serbian scholar Veselin Čajkanović, the ''zapis'' is inherited from Slavic paganism, the pre-Christian religion of the Serbs, in which it had been used as a temple. Religious practices The selected tree becomes a ''zapis'' through the rite of consecration perfo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acorn
The acorn is the nut (fruit), nut of the oaks and their close relatives (genera ''Quercus'', ''Notholithocarpus'' and ''Lithocarpus'', in the family Fagaceae). It usually contains a seedling surrounded by two cotyledons (seedling leaves), enclosed in a tough Nutshell, shell known as the pericarp, and borne in a cup-shaped Calybium, cupule. Acorns are long and on the fat side. Acorns take between 5 and 24 months (depending on the species) to mature; see the List of Quercus species, list of ''Quercus'' species for details of oak classification, in which acorn morphology (biology), morphology and phenology are important factors. Etymology The word ''acorn'' (earlier ''akerne'', and ''acharn'') is related to the gothic language, Gothic name ''akran'', which had the sense of "fruit of the unenclosed land". The word was applied to the most important forest produce, that of the oak. Geoffrey Chaucer, Chaucer spoke of "achornes of okes" in the 14th century. By degrees, popular etym ...
