Sorbus Thuringiaca
''Hedlundia thuringiaca'' is a widely cultivated species of ornamental shrub. It is cultivated by grafting. Description It has purple-grey bark, which is smooth but begins cracking and flaking as it matures. The leaves are narrowly ovate to elliptic (in shape) long and wide. They are lobed, except at the very tip, the lobes become deeper towards the base, becoming toothed. The leaves are glossy dark green above and grey and hair underneath. In late spring, it flowers with dense clusters of 5 petaled white flowers, which are wide. After flowering, it produces a rounded, bright red berry which is wide.Allen Coombes Taxonomy It is a diploid hybrid between ''Sorbus aucuparia'' and the diploid ''Aria edulis''. It is rare in the wild but occurs at scattered sites across much of EuropeChester, M.; Cowan, R.S.; Fay, M.F.; Rich, T.C.G. (2007). Parentage of endemic ''Sorbus'' L.

James Edward Smith (botanist)
Sir James Edward Smith (2 December 1759 – 17 March 1828) was an English botanist and founder of the Linnean Society. Early life and education Smith was born in Norwich in 1759, the son of a wealthy wool merchant. He started studying botanical science when he was eighteen. In 1781 he enrolled in the medical course at the University of Edinburgh, where he studied chemistry under Joseph Black, natural history under John Walker, and botany under John Hope, an early teacher of Linnaean taxonomy. He moved to London in 1783 to continue his studies and became a friend of Sir Joseph Banks, who was offered the entire collection of books, manuscripts and specimens of the Swedish natural historian and botanist Carl Linnaeus following the death of his son Carolus Linnaeus the Younger. Banks declined the purchase, but Smith borrowed money from his father and bought the collection for the price of £1,000 in 1784. Smith was elected a Fellow of the Royal Society in 1785.

Agricultural Research Service
The Agricultural Research Service (ARS) is the principal in-house research agency of the United States Department of Agriculture (USDA). ARS is one of four agencies in USDA's Research, Education and Economics mission area. ARS is charged with extending the nation's scientific knowledge and solving agricultural problems through its four national program areas: nutrition, food safety and quality; animal production and protection; natural resources and sustainable agricultural systems; and crop production and protection. ARS research focuses on solving problems affecting Americans every day. The ARS Headquarters is located in the Jamie L. Whitten Building on Independence Avenue in Washington, D.C., and the headquarters staff is located at the George Washington Carver Center (GWCC) in Beltsville, Maryland. For 2018, its budget was $1.2 billion. For 2023, the budget grew to $1.9 billion. Mission ARS conducts scientific research for the American public. Their main focus is on research ...

Flora Of Middle Europe
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was ...

Flora Of Ireland
Ireland is in the Atlantic European Province of the Circumboreal Region, a floristic region within the Holarctic. Composition of the flora Ireland has a small flora for a European country because of its small size, lack of geological and ecological variation and its Pleistocene history.

Flora Of Great Britain
The flora of Great Britain and Ireland is one of the best documented in the world. There are 1390 native species and over 1100 well-established non-natives documented on the islands. A bibliographic database of the species has been compiled by the Botanical Society of Britain and Ireland. The lists (spread across multiple pages due to size) give an English name and a scientific name for each species, and two symbols are used to indicate status (e for extinct species, and * for introduced species). * List of the vascular plants of Britain and Ireland (ferns and allies) covers ferns and allies (Lycopodiopsida, Equisetopsida and Pteridopsida) * List of the vascular plants of Britain and Ireland (conifers) covers the conifers ( Pinopsida) The remaining parts cover the flowering plants ( Magnoliopsida): * List of the vascular plants of Britain and Ireland (dicotyledons) * List of the vascular plants of Britain and Ireland (Rosaceae), covering the dicotyledon family Rosaceae * L ...

Hybrid Plants
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 morphological ...
