Tibouchina Araguaiensis
''Tibouchina araguaiensis'' is a species of flowering plant in the family Melastomataceae, native to north Brazil. It was first described by Paulo J.F. Guimarães in 2014. Description ''Tibouchina araguaiensis'' is a shrub that is very similar to ''Tibouchina papyrus''. Distinguishing characters include the triangular hypanthial scales which cover the entire hypanthium, and the abaxial leaf surface which is only sparsely covered by ciliate scales; in ''T. papyrus'', the prominent scales cover the entire lower leaf surface. These species also differ in their distribution; ''Tibouchina araguaiensis'' is found on the flat topography of Araguaia National Park, while ''T. papyrus'' is endemic to the higher elevation ''campos rupestres'' in southeast Tocantins and western Goiás. Distribution and habitat ''Tibouchina araguaiensis'' has been found only in Araguaia National Park The Araguaia National Park (''Parque Nacional do Araguaia'') is a national park located in Tocan ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melastomataceae
Melastomataceae is a family of dicotyledonous flowering plants found mostly in the tropics (two-thirds of the genera are from the New World tropics) comprising c. 175 genera and c. 5115 known species. Melastomes are annual or perennial herbs, shrubs, or small trees. Description The leaves of melastomes are somewhat distinctive, being opposite, decussate, and usually with 3-7 longitudinal veins arising either from the base of the blade, plinerved (inner veins diverging above base of blade), or pinnately nerved with three or more pairs of primary veins diverging from the mid-vein at successive points above the base. Flowers are perfect, and borne either singly or in terminal or axillary, paniculate cymes. Ecology A number of melastomes are regarded as invasive species once naturalized in tropical and subtropical environments outside their normal range. Examples are Koster's curse (''Clidemia hirta''), '' Pleroma semidecandrum'' and ''Miconia calvescens'', but many other specie ...

Tibouchina Papyrus
''Tibouchina papyrus'' Toledo was described in 1952. ''Tibouchina papyrus'' is a narrow endemic to the ''campos rupestres'' and is mainly found in three localities in the states of Goiás and Tocantins in central Brazil, including the Serra da Natividade. Abreu ''et al''. found that ''T. papyrus'' is a habitat-specialist on rocky outcrop ''cerrado'' which typically has shallow substrate and uneven topography, with sandstone soils and quartzite outcrops. This species has been collected at elevations between 500 metres and 1,100 metres. ''T. papyrus'' is listed as Vulnerable species, vulnerable by the IUCN. ''Tibouchina'' ''papyrus'' is locally known as “pau-papel”. The flowers of ''T. papyrus'' are Buzz pollination, buzz pollinated by large bees in the genera ''Xylocopa'', ''Bombus'' and ''Centris'', and the seeds are wind dispersed (autochory). Flowers have higher fruit production when cross-pollinated although they are not self-incompatible and can produce low numbers of frui ...

Endemism
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] |
Araguaia National Park
The Araguaia National Park (''Parque Nacional do Araguaia'') is a national park located in Tocantins state in the north of Brazil, between 09º51’—11º11’S and 49º57’—50º27’W.

Tocantins
Tocantins () is one of the 26 states of Brazil. It is the newest state, formed in 1988 and encompassing what had formerly been the northern two-fifths of the state of Goiás. Tocantins covers and had an estimated population of 1,496,880 in 2014. Construction of its capital, Palmas, began in 1989; most of the other cities in the state date to the Portuguese colonial period. With the exception of Araguaína, there are few other cities with a significant population in the state. The government has invested in a new capital, a major hydropower dam, railroads and related infrastructure to develop this primarily agricultural area. The state has 0.75% of the Brazilian population and is responsible for 0.5% of the Brazilian GDP. Tocantins has attracted hundreds of thousands of new residents, primarily to Palmas. It is building on its hydropower resources. The Araguaia and Tocantins rivers drain the largest watershed that lies entirely inside Brazilian territory. The Rio Tocantins ...

International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The stan ...
