Pleuranthodendron Lindenii
''Pleuranthodendron'' is a genus of flowering plants in the family Salicaceae. It consists of one species (''Pleuranthodendron lindenii'') of small to medium-sized trees native to the neotropics, specifically Central America and northern South America.Alford, M.H. 2006.

Nikolai Turczaninow
Nikolai Stepanovich Turczaninow ( ru , Николай Степанович Турчанинов, 1796 in Nikitovka, now in Krasnogvardeysky District, Belgorod Oblast, Russia – 1863 in Kharkov) was a Russian botanist and plant collector who first identified several genera, and many species, of plants. Education and career Born in 1796, Turczaninow attended high school in Kharkov. In 1814, he graduated from Kharkov University, before working as a civil servant for the Ministry of Finance in St. Petersburg. Soon after, in 1825, Turczaninow published his first botanical list. Despite being employed in a different field, he continued his largely self-taught botanical work. In 1828, he was assigned an administrative post in Irkutsk, Siberia. This allowed him to collect in the Lake Baikal area, which is known for its rich biodiversity. A spate of papers followed, and Turczaninow established his own herbarium containing plants from the region. In 1830, he was appointed a Fellow o ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

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] |
Salicaceae
The Salicaceae is the willow family of flowering plants. The traditional family (Salicaceae ''sensu stricto'') included the willows, poplar, aspen, and cottonwoods. Genetic studies summarized by the Angiosperm Phylogeny Group (APG) have greatly expanded the circumscription of the family to contain 56 genera and about 1220 species, including the Scyphostegiaceae and many of the former Flacourtiaceae. In the Cronquist system, the Salicaceae were assigned to their own order, Salicales, and contained three genera (''willow, Salix'', ''Populus'', and ''Chosenia''). Recognized to be closely related to the Violaceae and Passifloraceae, the family is placed by the APG in the order Malpighiales. Under the new circumscription, all members of the family are trees or shrubs that have Simple leaf, simple leaves with Phyllotaxis, alternate arrangement and temperate members are usually deciduous. Most members have serrate or dentate leaf margins, and those that have such toothed margins all e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Neotropics
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropics, tropical Ecoregion#Terrestrial, terrestrial ecoregions of the Americas and the entire South American temperate climate, temperate zone. Definition In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and coastal Central Florida are considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Phytochorion, Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic Floristic Kingdom, Antarctic kingdom. The ...

Flacourtiaceae
The Flacourtiaceae is a defunct family of flowering plants whose former members have been scattered to various families, mostly to the Achariaceae and Salicaceae. It was so vaguely defined that hardly anything seemed out of place there and it became a dumping ground for odd and anomalous genera, gradually making the family even more heterogeneous. In 1975, Hermann Sleumer noted that "Flacourtiaceae as a family is a fiction; only the tribes are homogeneous." In Cronquist's classification, the Flacourtiaceae included 79–89 genera and 800–1000 species. Of these, many, including the type genus ''Flacourtia'', have now been transferred to the Salicaceae in the molecular phylogeny-based classification, known as the APG IV system, established by the Angiosperm Phylogeny Group. In the list below, the Salicaceae are circumscribed broadly. Some taxonomists further divide the Salicaceae ''sensu lato ''Sensu'' is a Latin word meaning "in the sense of".

Hasseltia
''Hasseltia'' is a genus of flowering plants in the family Salicaceae. It contains four species of small to medium-sized trees native to the neotropics, ranging from Mexico south to Brazil and Bolivia.Alford, M.H. 2006. A new species of ''Hasseltia'' (Salicaceae) from Costa Rica and Panama. ''Brittonia'' 58(3): 277-284. The genus is named for the Dutch physician and botanist Johan Conrad van Hasselt. ''Hasseltia'' is unique among Salicaceae in that the species have pseudo-axile placentation, compound umbellate inflorescences, and a pair of glands embedded in the base of the leaf blades.

Macrothumia
''Macrothumia kuhlmannii'' is a species of trees native to Bahia, Espírito Santo, and Minas Gerais states of Brazil and is the only member of the genus ''Macrothumia''. Formerly classified in the genus ''Banara'' in the family Flacourtiaceae, phylogenetic analyses based on DNA data indicate that this species, along with its close relatives in ''Ahernia'', ''Hasseltia'', and ''Pleuranthodendron'' are better placed in a broadly circumscribed Salicaceae. ''Macrothumia'' differs from its close relatives in having a congested fascicle- or umbel-like inflorescence and a large (>3 cm diameter) fruit In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particu ....

Flora Of Central America
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] |
