Fallopia Schischkinii
''Fallopia'' is a genus of about 12 species of flowering plants in the buckwheat family, often included in a wider treatment of the related genus ''Polygonum'' in the past, and previously including ''Reynoutria''. The genus is native to temperate and subtropical regions of the Northern Hemisphere, but species have been introduced elsewhere. The genus includes species forming vines and shrubs. Description Species of ''Fallopia'' grow as vines, lianas, shrubs or subshrubs. Unlike species of the related genus ''Duma'', they do not have thorn-like tips to their branches. Nectaries are present outside the flowers (extrafloral). Plants usually have bisexual flowers. More rarely they may be dioecious, each plant only having flowers with either functional stamens or a functional pistil. The flowers are arranged in a raceme. The tepals of the flowers are dry and paper-like when mature. The flowers have short styles with partially fused stigmas forming a "head". The fruits are achenes wit ...

Gynoecium
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are called ''pi ...

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images. See also *Australian Plant Name Index *Convention on Biological Diversity *World Flora Online *Tropicos Tropicos is an online botanical database containing taxonomic information on plants, mainly from the Neotropical realm (Central, and South America). It is maintained by the Missouri Botanical Garden and was established over 25 y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muehlenbeckia
''Muehlenbeckia'' or maidenhair is a genus of flowering plants in the family Polygonaceae. It is native to the borders of the Pacific, including South and North America, Papua New Guinea and Australasia. It has been introduced elsewhere, including Europe. Species vary in their growth habits, many being vines or shrubs. In some environments, rampant species can become weedy and difficult to eradicate. Description Species of ''Muehlenbeckia'' vary considerably in their growth habits; they may be perennials, vinelike, or shrubs. All have rhizomatous roots. Their leaves are arranged alternately on the stem, usually with stalks ( petioles), but sometimes stalkless (sessile). The brownish ocrea is short and tubular, soon disintegrating. The inflorescences may be terminal or axillary, and are in the form of spikes or clusters, with at most very short peduncles (flowering stems). Individual flowers have pedicels (stalks). The flowers may be bisexual or unisexual, with sometimes a mixtur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polygonoideae
Polygonoideae is a subfamily of plants in the family Polygonaceae. It includes a number of plants that can be highly invasive, such as Japanese knotweed, ''Reynoutria japonica'', and its hybrid with '' R. sachalinensis'', ''R.'' × ''bohemica''. Boundaries between the genera placed in the subfamily and their relationships have long been problematic, but a series of molecular phylogenetic studies have clarified some of them, resulting in the division of the subfamily into seven tribes. Taxonomy Phylogeny A 2015 molecular phylogenetic study suggested that the genera and tribes in Polygonoideae were related as shown in the following cladogram. ''Rumex'' included ''Emex'', and ''Fallopia'' was not monophyletic, with some species placed outside the main group in the tribe Polygoneae, and some others grouping with '' Pteroxygonum'', placed in the tribe Pteroxygoneae. Genera Some of the boundaries between the genera are not settled ; in particular, ''Fallopia'' is at least paraphyle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Carl Meissner
Carl Daniel Friedrich Meissner (1 November 1800 – 2 May 1874) was a Swiss botanist. Biography Born in Bern, Switzerland on 1 November 1800, he was christened Meisner but later changed the spelling of his name to Meissner. For most of his 40-year career he was Professor of Botany at University of Basel. He made important contributions to the botanical literature, including the publication of the comprehensive work ''Plantarum Vascularum Genera'', and publications of monographs on the families Polygonaceae (especially the genus ''Polygonum''), Lauraceae, Proteaceae, Thymelaeaceae and Hernandiaceae. His contributions to the description of the Australian flora were prolific; he described hundreds of species of Australian Proteaceae, and many Australian species from other families, especially Fabaceae, Mimosaceae and Myrtaceae. His health deteriorated after 1866, and he was less active. He died in Basel on 2 May 1874. See also * Meissner's taxonomic arrangement of Banksia Carl ...

Anatomy
Anatomy () is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated, both over immediate and long-term timescales. Anatomy and physiology, which study the structure and function (biology), function of organisms and their parts respectively, make a natural pair of related disciplines, and are often studied together. Human anatomy is one of the essential basic research, basic sciences that are applied in medicine. The discipline of anatomy is divided into macroscopic scale, macroscopic and microscopic scale, microscopic. Gross anatomy, Macroscopic anatomy, or gross anatomy, is the examination of an ...

Padua
Padua ( ; it, Padova ; vec, Pàdova) is a city and ''comune'' in Veneto, northern Italy. Padua is on the river Bacchiglione, west of Venice. It is the capital of the province of Padua. It is also the economic and communications hub of the area. Padua's population is 214,000 (). The city is sometimes included, with Venice (Italian ''Venezia'') and Treviso, in the Padua-Treviso-Venice Metropolitan Area (PATREVE) which has a population of around 2,600,000. Padua stands on the Bacchiglione, Bacchiglione River, west of Venice and southeast of Vicenza. The Brenta River, which once ran through the city, still touches the northern districts. Its agricultural setting is the Venetian Plain (''Pianura Veneta''). To the city's south west lies the Colli Euganei, Euganaean Hills, praised by Lucan and Martial, Petrarch, Ugo Foscolo, and Percy Bysshe Shelley, Shelley.

Botanical Garden
A botanical garden or botanic gardenThe terms ''botanic'' and ''botanical'' and ''garden'' or ''gardens'' are used more-or-less interchangeably, although the word ''botanic'' is generally reserved for the earlier, more traditional gardens, and is the more usual term in the United Kingdom. is a garden with a documented collection of living plants for the purpose of scientific research, conservation, display, and education. Typically plants are labelled with their botanical names. It may contain specialist plant collections such as cactus, cacti and other succulent plants, herb gardens, plants from particular parts of the world, and so on; there may be greenhouses, shadehouses, again with special collections such as tropical plants, alpine plants, or other exotic plants. Most are at least partly open to the public, and may offer guided tours, educational displays, art exhibitions, book rooms, open-air theatrical and musical performances, and other entertainment.

Gabriele Falloppio
Gabriele Falloppio (also Gabrielle Falloppia) (1522/23 – 9 October 1562) was an Italian anatomist often known by his Latin name Fallopius. He was one of the most important human anatomy, anatomists and physicians of the sixteenth century, giving his name to the Fallopian tube. Life Falloppio grew up in Modena. His father died early but thanks to the support of affluent relatives he enjoyed are thorough humanist education in Modena, learning Latin and Greek and moving in the local circle of humanist scholars. He was for some years in the service of the Church, among others as a kind of warden at Modena's cathedral, but soon turned to medicine. In 1544, he performed a public anatomy in Modena. In 1545, at the latest, he began to study medicine at the University of Ferrara, at that time one of the best medical schools in Europe. It was there also that he much later, in 1552, when he was already professor in Padua, received his medical doctorate under the guidance of Antonio Musa ...

Achene
An achene (; ), also sometimes called akene and occasionally achenium or achenocarp, is a type of simple dry fruit produced by many species of flowering plants. Achenes are monocarpellate (formed from one carpel) and indehiscent (they do not open at maturity). Achenes contain a single seed that nearly fills the pericarp, but does not adhere to it. In many species, what is called the "seed" is an achene, a fruit containing the seed. The seed-like appearance is owed to the hardening of the fruit wall (pericarp), which encloses the solitary seed so closely as to seem like a seed coat. Examples The fruits of buttercup, buckwheat, caraway, quinoa, amaranth, and cannabis are typical achenes. The achenes of the strawberry are sometimes mistaken for seeds. The strawberry is an accessory fruit with an aggregate of achenes on its outer surface, and what is eaten is accessory tissue. A rose produces an aggregate of achene fruits that are encompassed within an expanded hypanthium (aka f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
