Odontadenia Macrantha
''Odontadenia macrantha'' is a vine of the family Apocynaceae native to Central and South America. The cylindrical stem is either woody or just woody at the base. The smooth oval leaves are long by wide, and sit on long petioles. They are oppositely arranged on the stem. The orange or yellow flowers are in diameter with a long tube. However, flower shape and colour can vary considerably. Flowering takes place all year, with a peak from December to August, while fruiting peaks from April to October; the smooth seed pods are long by wide. It was originally described as ''Echites macrantha'' by Austrian botanists Johann Jacob Roemer and Josef August Schultes in 1819 from material from Brazil. The species name is derived from the Ancient Greek words ''makros'' "long" and ''anther'' "flower(ing)". George Bentham described it as ''Odontadenia speciosa'' in 1841 from material collected from Guyana in 1837. It is the type species In zoological nomenclature, a type species (''sp ...

Johann Jacob Roemer
Johann Jacob Roemer (8 January 1763, Zurich – 15 January 1819) was a physician and professor of botany in Zurich, Switzerland. He was also an entomologist. With Austrian botanist Joseph August Schultes, he published the 16th edition of Carl Linnaeus' ''Systema Vegetabilium''. Roemer's ''Genera insectorum'' is a most attractive Swiss publication on entomology. The splendid hand-coloured plates were drawn and engraved by the Swiss artist J.R. Schellenberg, an entomologist himself and therefore familiar with structural details. In 1793, he was elected a foreign member of the Royal Swedish Academy of Sciences. The botanical genus ''Roemeria'' from the family Papaveraceae is named after him. Works *''Magazin für die Botanik'', vols. 1–4; 1787–1791, with publicist Paul Usteri (1768-1831). Afterwards Roemer continued this series as ''Neues Magazin für die Botanik''. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Josef August Schultes
Josef (Joseph) August Schultes (15 April 1773 in Vienna – 21 April 1831 in Landshut) was an Austrian botanist and professor from Vienna. Together with Johann Jacob Roemer (1763–1819), he published the 16th edition of Linnaeus' ''Systema Vegetabilium''. In 1821, he was elected a foreign member of the Royal Swedish Academy of Sciences. He was the father of Julius Hermann Schultes (1804-1840). In 1796 he received his doctorate at Vienna, where he was a student of Johann Peter Frank (1745-1821). Later on, he served as a professor of botany and natural history at the Theresianum in Vienna, followed by professorships at the Universities of Krakow (1806) and Innsbruck (1808). In 1809 he succeeded Franz von Paula Schrank (1747-1835) at the University of Landshut as a professor of natural history and botany. At Landshut, he also served as a medical director. Swedish botanist Carl Peter Thunberg commissioned Schultes to edit the first complete edition of his Flora Capensis, which ...

Friedrich Markgraf
Friedrich Markgraf (1 February 1897 in Berlin-Friedenau – 8 March 1987 in Zurich) was a German botanist. Life and work After secondary school, Markgraf studied biology at the Friedrich Wilhelm University Berlin. In 1922 he was awarded a Ph.D. for a thesis on the subject of a botanic-ecological study of the Bredower forest near Berlin. After his habilitation he became first a professor of botany at the Friedrich Wilhelm University in Berlin and then at the Ludwig Maximilian University of Munich and director of the Botanical Garden Munich-Nymphenburg (1956-1958). Markgraf was also visiting professor of botany at the University of Zurich. During his teaching and research activities, he was primarily concerned with questions of botanical systematics, plant morphology and phytogeography and he also undertook research while travelling in the Mediterranean. In particular he made an important start on the study of the local flora of Albania. He acted as the Regional Adviser o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apocynaceae
Apocynaceae (from ''Apocynum'', Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae (now known as Asclepiadoideae) is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here. Many species are tall trees found in tropical forests, but some grow in tropical dry (xeric) environments. Also perennial herbs from temperate zones occur. Many of these plants have milky latex, and many species are poisonous if ingested, the family being rich in genera containing alkaloids and cardiac glycosides, those containing the latter often finding use as arrow poisons. Some genera of Apocynaceae, such as '' Adenium'', bleed clea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phyllotaxis
In botany, phyllotaxis () or phyllotaxy is the arrangement of leaf, leaves on a plant stem. Phyllotactic spirals form a distinctive class of patterns in nature. Leaf arrangement The basic leaf#Arrangement on the stem, arrangements of leaves on a stem are opposite and alternate (also known as spiral). Leaves may also be Whorl (botany), whorled if several leaves arise, or appear to arise, from the same level (at the same Node (botany), node) on a stem. With an opposite leaf arrangement, two leaves arise from the stem at the same level (at the same Node (botany), node), on opposite sides of the stem. An opposite leaf pair can be thought of as a whorl of two leaves. With an alternate (spiral) pattern, each leaf arises at a different point (node) on the stem. Distichous phyllotaxis, also called "two-ranked leaf arrangement" is a special case of either opposite or alternate leaf arrangement where the leaves on a stem are arranged in two vertical columns on opposite sides of t ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oxford University Press
Oxford University Press (OUP) is the university press of the University of Oxford. It is the largest university press in the world, and its printing history dates back to the 1480s. Having been officially granted the legal right to print books by decree in 1586, it is the second oldest university press after Cambridge University Press. It is a department of the University of Oxford and is governed by a group of 15 academics known as the Delegates of the Press, who are appointed by the vice-chancellor of the University of Oxford. The Delegates of the Press are led by the Secretary to the Delegates, who serves as OUP's chief executive and as its major representative on other university bodies. Oxford University Press has had a similar governance structure since the 17th century. The press is located on Walton Street, Oxford, opposite Somerville College, in the inner suburb of Jericho. For the last 500 years, OUP has primarily focused on the publication of pedagogical texts and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Bentham
George Bentham (22 September 1800 – 10 September 1884) was an English botanist, described by the weed botanist Duane Isely as "the premier systematic botanist of the nineteenth century". Born into a distinguished family, he initially studied law, but had a fascination with botany from an early age, which he soon pursued, becoming president of the Linnaean Society in 1861, and a fellow of the Royal Society in 1862. He was the author of a number of important botanical works, particularly flora. He is best known for his taxonomic classification of plants in collaboration with Joseph Dalton Hooker, his ''Genera Plantarum'' (1862–1883). He died in London in 1884. Life Bentham was born in Stoke, Plymouth, on 22 September 1800.Jean-Jacques Amigo, « Bentham (George) », in Nouveau Dictionnaire de biographies roussillonnaises, vol. 3 Sciences de la Vie et de la Terre, Perpignan, Publications de l'olivier, 2017, 915 p.

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Flora Of Oaxaca
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. 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 first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
