Rubia Agostinhoi
''Rubia agostinhoi'' is a climbing plant species of the Rubiaceae family endemic to the Azores It was defined by ecologist Pierre Dansereau and Pinto da Silva in 1977. Description ''Rubia agostinhoi'' has branched, glabrous, brushed or smooth stems, up to long. It has narrowly elliptical to linear or oblanceolate leathery, dark green leaves with very small, slightly revolted spines in the margins. Leaves of the side shoots are shorter and smaller in length than those of the main stem. Flower stems are long and usually very flowery. Fruits are , globose and shiny black when ripe.

Pierre Dansereau
Pierre Dansereau (October 5, 1911 – September 28, 2011) was a Canadian ecologist from Quebec known as one of the "fathers of ecology". Biography Born in Outremont, Quebec (now part of Montreal), he received a Bachelor of Science in Agriculture (B.Sc.A.) in 1936 and a Ph.D. in Biological Science in 1939 from the University of Geneva.

António Rodrigo Pinto Da Silva
António Rodrigo Pinto da Silva (Porto, 13 March 1912 – Lisbon, 28 September 1992), often referred to as A.R. Pinto da Silva or P. Silva, was a Portuguese botanist who distinguished himself as a taxonomist and Phytosociology, phytosociologist when he collaborated with Swiss botanist Josias Braun-Blanquet and also with Pierre Dansereau. His studies on Taxonomy (biology), taxonomy and floristic yielded a substantial number of new Taxon, taxa and a better knowledge about many plants and its Botanical nomenclature, nomenclature. He organized the Estação Agronómica Nacional's (National Agronomic Station) herbarium, which he rose from 3000 to almost 100,000 entries. He was a pioneer on ethnobotany studies in Portugal and published several contributions on vernacular nomenclature of Portuguese flora, cultivated plants and popular use of wild plants as food. For half a century he helped archaeologists, having published numerous works on paleoethnobotany, among more than 300 articles, n ...

Catalogue Of Life
The Catalogue of Life is an online database that provides an index of known species of animals, plants, fungi, and microorganisms. It was created in 2001 as a partnership between the global Species 2000 and the American Integrated Taxonomic Information System. The Catalogue is used by research scientists, citizen scientists, educators, and policy makers. The Catalogue is also used by the Biodiversity Heritage Library, the Barcode of Life Data System, Encyclopedia of Life, and the Global Biodiversity Information Facility. The Catalogue currently compiles data fro165 peer-reviewed taxonomic databasesthat are maintained by specialist institutions around the world. , the COL Checklist lists 2,067,951 of the world's 2.2m extant species known to taxonomists on the planet at present time. Structure The Catalogue of Life employs a simple data structure to provide information on synonymy, grouping within a taxonomic hierarchy, common names, distribution and ecological environment.

Rubiaceae
The Rubiaceae are a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 13,500 species in about 620 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include ''Coffea'', the source of coffee, '' Cinchona'', the source of the antimalarial alkaloid quinine, ornamental cultivars (''e.g.'', '' Gardenia'', ''Ixora'', ''Pentas''), and historically some dye plants (''e.g.'', ''Rubia''). Description The Rubiaceae are morphologically easily recognizable as a coherent group by a combination of characters: opposite or whorled leaves that are simple and entire, interpetiolar stipules, tubu ...

Endemic
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Graciosa
Graciosa Island () (literally "graceful" or "enchanting" in Portuguese) is referred to as the ''White Island'', the northernmost of the Central Group of islands in the Azores. The ovular Portuguese island has an area of , a length of and a width of . It is a volcanic island, dominated by a central caldera (the Caldeira) located in the southeast. History In addition to the other islands of the Central Group, Graciosa was explored by Portuguese navigators during the first quarter of the 15th century, although there exist no accounts of the first sighting of the island. May 2, 1450 has frequently been referred to as the date of the island's "discovery", although there exists no documentation to support this date. Paradoxically, it is clear that in 1440, by order of Prince Henry the Navigator, cattle and swine were settled on the island in order to facilitate colonization. Similarly, it is unclear the names of the first settlers to colonize the island, although around 1450 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubia
''Rubia'' is the type genus of the Rubiaceae family of flowering plants, which also contains coffee. It contains around 80 species of perennial scrambling or climbing herbs and subshrubs native to the Old World. The genus and its best-known species are commonly known as madder, e.g. '' Rubia tinctorum'' (common madder), ''Rubia peregrina'' (wild madder), and ''Rubia cordifolia'' (Indian madder). Uses ''Rubia'' was an economically important source of a red pigment in many regions of Asia, Europe and Africa. The genus name ''Rubia'' derives from the Latin ' meaning "red". The plant's roots contain an anthracene compound called alizarin that gives its red colour to a textile dye known as Rose madder. It was also used as a colourant, especially for paint, that is referred to as Madder lake. The synthesis of alizarin greatly reduced demand for the natural compound. In Georgia, Rubia is used for dying Easter eggs in red. History Several species, such as '' Rubia tinctorum'' in Eu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1977
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have l ...
