Truman George Yuncker
Truman George Yuncker (March 20, 1891 – January 8, 1964) was a taxonomic botanist best known for his work in the family Piperaceae. Yuncker first taught at Manual High School in Indianapolis, Indiana. After service in World War I, he received his doctorate from the University of Illinois in 1919. Soon after, he became a faculty member at DePauw University and became head of the botany and bacteriology department in 1921 and held that post until retirement in 1956. During his tenure he described 839 new species, 211 new varieties and 25 new formae in the Piperaceae. He wrote the treatment of that family in almost every regional flora published during his lifetime. His early studies were on the genus ''Cuscuta'', in which he described 67 new species and 39 new varieties. Yuncker acquired an impressive collection of plant samples which became an herbarium maintained by DePauw. DePauw sold the collection to the New York Botanical Garden The New York Botanical Garden (NYBG) is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant
Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts ...

Piperaceae
The Piperaceae (), also known as the pepper family, are a large family (biology), family of flowering plants. The group contains roughly 3,600 currently accepted species in five genera. The vast majority of species can be found within the two main genera: ''Piper (plant), Piper'' (2,171 species) and ''Peperomia'' (over 1,000 species). Members of the Piperaceae may be small trees, shrubs, or herbs. The distribution of this group is best described as pantropical. The best-known species, ''Piper nigrum'', yields most peppercorns that are used as spices, including black pepper, although its relatives in the family include many other spices. The family Piperaceae is unrelated to the family Solanaceae, which includes bell peppers and chili peppers, which are so named due to Europeans taking part in the Columbian exchange mistakenly believing the spicy fruits were a variety of the black pepper plant. Etymology The name Piperaceae is derived from the Sanskrit term ''pippali'', . Taxo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Ecuador
Ecuador, officially the Republic of Ecuador, is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. It also includes the Galápagos Province which contains the Galapagos Islands in the Pacific, about west of the mainland. The country's Capital city, capital is Quito and its largest city is Guayaquil. The land that comprises modern-day Ecuador was once home to several groups of Indigenous peoples in Ecuador, indigenous peoples that were gradually incorporated into the Inca Empire during the 15th century. The territory was Spanish colonization of the Americas, colonized by the Spanish Empire during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as a sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its million people being mestizos, followed by large minorities of Europe ...

Piper (plant)
''Piper'', the pepper plants or pepper vines, is an economically and ecologically important genus in the family Piperaceae. It contains about 1,000–2,000 species of shrubs, herbs, and lianas, many of which are dominant species in their native habitat. The diversification of this taxon is of interest to understanding the evolution of plants. Pepper plants belong to the magnoliids, which are angiosperms but neither monocots nor eudicots. Their family, Piperaceae, is most closely related to the lizardtail family ( Saururaceae), which in fact generally look like smaller, more delicate and amphibious pepper plants. Both families have characteristic tail-shaped inflorescences covered in tiny flowers. A somewhat less close relative is the pipevine family ( Aristolochiaceae). A well-known and very close relative – being also part of the Piperaceae – are the radiator plants of the genus '' Peperomia''. The scientific name ''Piper'' and the common name "pepper" are derived f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Plants
In September 2016, the International Union for Conservation of Nature (IUCN) listed 3654 endangered plant species. Of all evaluated plant species, 17% are listed as endangered. The IUCN also lists 99 subspecies and 101 varieties as endangered. No subpopulations of plants have been evaluated by the IUCN. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered plants are listed separately. There are 6147 plant species which are endangered or critically endangered. Additionally 1674 plant species (7.6% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
