Van-royena
''Van-royena'' is a genus of the plant family Sapotaceae described as a genus in 1963. There is only one known species, ''Van-royena castanosperma'', which is endemic to the Cook region in northern Queensland. It grows at altitudes of above sea level, in rainforests.William Cooper and Wendy Cooper Description It is a tree that can grow up to tall, with a stem that's bark exudates (fluid emitted by an organism through pores or a wound) quite conspicuous. The narrow, yellowish, vertical stripes in the blaze shaded bark layer is thin, about 2-3 mm. It has simple leaves, that are long and wide. The Petiole (botany), petioles (leaf stalks) and twigs produce a milky exudate. It has a corolla (flower), corolla (the collective term for the petals) is about long, usually glabrous (lacking surface ornamentation) on both surfaces but the margins of the lobes are minutely ciliate (has small hairs). The stamens are attached well below the throat of the flower tube. The staminodes (steri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sapotaceae
240px, '' Madhuca longifolia'' var. ''latifolia'' in Narsapur, Medak district, India The Sapotaceae are a family (biology), family of flowering plants belonging to the order (biology), order Ericales. The family includes about 800 species of evergreen trees and shrubs in around 65 genera (35-75, depending on generic definition). Their distribution is pantropical. Many species produce edible fruits, or white blood-sap that is used to cleanse dirt, organically and manually, while others have other economic uses. Species noted for their edible fruits include ''Manilkara'' (sapodilla), ''Chrysophyllum cainito'' (star-apple or golden leaf tree), and ''Pouteria'' ('' abiu, canistel, lúcuma'', mamey sapote). ''Vitellaria paradoxa'' (''shi'' in several languages of West Africa and ''karité'' in French; also anglicized as shea) is also the source of an oil-rich nut, the source of edible shea butter, which is the major lipid source for many African ethnic groups and is also used in t ...

André Aubréville
André Aubréville (30 November 1897, in Pont-Saint-Vincent (Meurthe-et-Moselle) – 11 August 1982, in Paris) was a French botanist, professor at the National Museum of Natural History, France, National Museum of Natural History in Paris and a member of the Academy of Sciences. He was the first scientist to introduce the term "desertification" (in his 1949 book: ''Climats, forêts et désertification de l'Afrique tropicale'' (Climates, Forests, and Desertification of Tropical Africa), and wrote a number of floras of former French colonies. Biography Following his service (as a youth) in the First World War, André Aubréville entered the École Polytechnique (promotion 20 "special") and obtained an engineering degree in 1922. Attracted by the botany of tropical forests, he then studied at the French National School of Forestry, École nationale des eaux et forêts in Nancy, graduating as ''Ingénieur des Eaux et Forêts des Colonies'' (Engineer of Waters and Forests of the Colo ...

Flora Of Queensland
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1963
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 lost the ability t ...

Monotypic Ericales Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...

Endemic Flora Of Australia
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agricultural Research Service
The Agricultural Research Service (ARS) is the principal in-house research agency of the United States Department of Agriculture (USDA).
