Perleb
Karl Julius Perleb (20 June 1794, Konstanz – 8 June 1845, Freiburg im Breisgau) (also known as Carl Julius Perleb) was a German botanist and naturalist. Life From 1809 to 1811, Karl Julius Perleb studied at the University of Freiburg and earned a doctorate in philosophy and in 1815 a degree in medicine. He lived in Vienna for a brief period of time. In 1818 he returned to the University of Freiburg and began a post-doctoral fellowship. He remained at the university for the remainder of his life. He became an associate professor of natural history in 1821, and in 1823 he became a full professor. From 1828 to 1845 he served as director of the Freiburg Botanical Garden. In 1838 he was appointed prorector at Freiburg University. He left his library and herbarium to the university, together with money for its administration and for travel grants for young scholars of the natural sciences.

Freiburg Botanical Garden
Freiburg Botanical Garden (German: ''Botanischer Garten Freiburg'' or ''Botanischer Garten der Albert-Ludwigs-Universität Freiburg'') is a botanical garden in the Herdern district at Schänzlestraße 1, Freiburg im Breisgau, Baden-Württemberg, Germany and is associated with the University of Freiburg as the "Forschungs- und Lehrgarten der Universität Freiburg" (Garden for research and teaching of the University of Freiburg) of the Faculty of Biology. The current director of the garden is Professor Dr. Thomas Speck. The garden was founded in 1620 by the University of Freiburg. A building on the same property was rebuilt as a hospital for members of the university, which also served for anatomy training. It was one of the first botanical gardens in Germany. The garden was originally part of the University of Freiburg Faculty of Medicine. The first director of the garden was Jacobus Walter (born 1655), a professor of medicine who was also responsible for botany. During the Thi ...

Bauhinia
''Bauhinia'' () is a large genus of flowering plants in the subfamily Cercidoideae and tribe Bauhinieae, in the large flowering plant family Fabaceae, with a pantropical distribution. The genus was named after the Bauhin brothers Gaspard and Johann, Swiss-French botanists. Many species are widely planted in the tropics as orchid trees, particularly in India, Sri Lanka, Vietnam, Nepal and south-eastern China. Other common names include mountain ebony and ''kachnar''. Before the family was reorganised, a number of genera including the lianas of genus '' Phanera'' were placed here (see related genera). In the United States, the trees grow in Hawaii, coastal California, Arizona, Texas, Louisiana, and Florida. There are native species, like '' Bauhinia lunarioides'' native to Texas and widely planted in the Southwest as a landscape plant. Parts of some species of bauhinia like ''B. purpurea'' and ''B. malabarica'' are used in Filipino cuisine (known collectively as ''alinbánba ...

Konstanz
Konstanz ( , , , ), traditionally known as Constance in English, is a college town, university city with approximately 83,000 inhabitants located at the western end of Lake Constance in the Baden-Württemberg state of south Germany. The city houses the University of Konstanz and was the residence of the Roman Catholic Diocese of Konstanz for more than 1,200 years. Location The city is located in the state of Baden-Württemberg and situated at the banks of Lake Constance (''Bodensee'' in German). The river Rhine, which starts in the Swiss Alps, passes through Lake Constance and leaves it, considerably larger, by flowing under a bridge connecting the two parts of the city. North of the river lies the larger part of the city with residential areas, industrial estates, and the University of Konstanz; while south of the river is the old town, which houses the administrative centre and shopping facilities in addition to the ''Hochschule'' or the ''University of Applied Sciences''.

University Of Freiburg Faculty Of Biology
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities in the Middl ...

Freiburg
Freiburg im Breisgau or simply Freiburg is the List of cities in Baden-Württemberg by population, fourth-largest city of the German state of Baden-Württemberg after Stuttgart, Mannheim and Karlsruhe. Its built-up area has a population of about 355,000 (2021), while the greater Freiburg metropolitan area ("Einzugsgebiet") has about 660,000 (2018). Freiburg is located at the southwestern foothills of the Black Forest, on the Dreisam River, a tributary of the Elz (Rhine), Elz. It is Germany's southwestern- and southernmost city with a population exceeding 100,000. It lies in the Breisgau, one of Germany's warmest regions, in the south of the Upper Rhine Plain. Its city limits reach from the Schauinsland summit () in the Black Forest to east of the French border, while Switzerland is to the south.

John Ray
John Ray Fellow of the Royal Society, FRS (November 29, 1627 – January 17, 1705) was a Christian England, English Natural history, naturalist widely regarded as one of the earliest of the English parson-naturalists. Until 1670, he wrote his name as John Wray. From then on, he used 'Ray', after "having ascertained that such had been the practice of his family before him". He published important works on botany, zoology, and natural theology. His classification of plants in his ''Historia Plantarum (Ray book), Historia Plantarum'', was an important step towards modern Taxonomy (biology), taxonomy. Ray rejected the system of dichotomy, dichotomous division by which species were classified by repeated sub-division into groups according to a pre-conceived series of characteristics they have or have not, and instead classified plants according to similarities and differences that emerged from observation. He was among the first to attempt a biological definition for the concept of ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petals
Petals are modified leaves that form an inner whorl surrounding the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually surrounded by an outer whorl of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as '' Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly coloured tepals. Since they inclu ...

Calyciflorae
Calyciflorae is a grouping of plants that is no longer used by botanists. Augustin Pyramus de Candolle defined it as a subclass within the class Dicotyledoneae. It overlapped largely with the modern Rosids group. The group Calyciflorae was defined as: * Flowers with sepal A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 Etymology The term ''sepalum'' ...s united at least at the base ( gamosepalous), a "torus" (disc) at the base of the calyx from which the petals and stamens appear to emerge, the ovary either free or attached to the calyx.

Class (biology)
In biological classification, class () is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. It is a group of related taxonomic orders. Other well-known ranks in descending order of size are domain, kingdom, phylum, order, family, genus, and species, with class ranking between phylum and order. History The class as a distinct rank of biological classification having its own distinctive name – and not just called a ''top-level genus'' ''(genus summum)'' – was first introduced by French botanist Joseph Pitton de Tournefort in the classification of plants that appeared in his '' Eléments de botanique'' of 1694. Insofar as a general definition of a class is available, it has historically been conceived as embracing taxa that combine a distinct ''grade'' of organization—i.e. a 'level of complexity', measured in terms of how differentiated their organ systems are into distinct regions or sub-organs—with a distinct ''type'' of construction, whic ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...
