Andrachne
''Andrachne'' is a genus of flowering plants in the family Phyllanthaceae described by Linnaeus in 1753. It is one of eight genera in the tribe Poranthereae. Maria S. Vorontsova and Petra Hoffmann. 2008. "A phylogenetic classification of tribe Poranthereae (Phyllanthaceae)." ''Kew Bulletin'' 63(1):41-59. They are monoecious herbs or subshrubs, native to semideserts and desert margins of the Americas, southern Europe, North Africa, and South Asia. Linnaeus took the name from Theophrastus, but it is not clear to which plant Theophrastus applied the name.Umberto Quattrocchi. 2000. ''CRC World Dictionary of Plant Names'' volume I, page 135.

Phyllanthaceae
Phyllanthaceae is a family of flowering plants in the eudicot order Malpighiales. It is most closely related to the family Picrodendraceae.Kenneth J. Wurdack and Charles C. Davis. 2009. "Malpighiales phylogenetics: Gaining ground on one of the most recalcitrant clades in the angiosperm tree of life." ''American Journal of Botany'' 96(8):1551-1570. (see ''External links'' below) The Phyllanthaceae are most numerous in the tropics, with many in the south temperate zone, and a few ranging as far north as the middle of the north temperate zone.Petra Hoffman. 2007.

Phyllanthopsis
''Phyllanthopsis'' is a genus of flowering plants in the family Phyllanthaceae. It is one of the eight genera in the tribe Poranthereae. It has two species. The type species is '' Phyllanthopsis phyllanthoides''. ''Phyllanthopsis'' is native to Texas, Oklahoma and Mexico. It consists of monoecious or dioecious shrubs. ''Phyllanthopsis phyllanthoides'' had been placed in ''Leptopus'' or '' Andrachne'' and '' Phyllanthopsis arida'' had been placed in ''Andrachne''. In 2007, a molecular phylogenetic study showed that these two species did not belong in either of these genera because they formed a clade that is sister to a clade consisting of ''Leptopus'' and ''Actephila ''Actephila'' is a genus of plants in the family Phyllanthaceae, first described as a genus in 1826.

Poranthereae
Poranthereae is a tribe in the plant family Phyllanthaceae. It is one of ten tribes in the family, and one of four tribes in the subfamily Phyllanthoideae. Poranthereae comprises about 111 species, distributed into eight genera. The largest genera and the number of species in each are ''Actephila'' (31), ''Meineckia'' (30), and ''Andrachne'' (22). The tribe consists of herbs, shrubs, and small to medium trees. They have a cosmopolitan distribution, occurring on all continents, except Antarctica. The circumscription and classification of Poranthereae were substantially revised following phylogenetic analysis of DNA sequences from members of the family Phyllanthaceae. Within Poranthereae, groups of related genera are strongly correlated with habitat and geographical distribution. For example, ''Notoleptopus'', ''Pseudophyllanthus'', and ''Poranthera'' are restricted to the Old World Southern Hemisphere.

Actephila
''Actephila'' is a genus of plants in the family Phyllanthaceae, first described as a genus in 1826. It is one of 8 genera in the tribe Poranthereae, and is most closely related to '' Leptopus''. The name of the genus is derived from two Greek words, ''akte'', "the seashore", and ''philos'', "loving". It refers to a coastal habitat.Umberto Quattrocchi. 2000. ''CRC World Dictionary of Plant Names'' volume I. CRC Press: Boca Raton; New York; Washington,DC;, USA. London, UK. (vol. I). (see ''External links'' below). ''Actephila'' consists of monoecious trees, shrubs, and subshrubs. The genus is not well understood and is in much need of revision. It is native to Southeast Asia, China, the Himalayas, Papuasia and northern Australia. ;Species ;Formerly included moved to other genera: ''Cleidion Excoecaria Pentabrachion Phyllanthus ''Phyllanthus'' is the largest genus in the plant family Phyllanthaceae.

Euphorbia
''Euphorbia'' is a very large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae. "Euphorbia" is sometimes used in ordinary English to collectively refer to all members of Euphorbiaceae (in deference to the type genus), not just to members of the genus. Euphorbias range from tiny annual plants to large and long-lived trees. The genus has roughly 2,000 members, making it one of the largest genera of flowering plants. It also has one of the largest ranges of chromosome counts, along with ''Rumex'' and ''Senecio''. ''Euphorbia antiquorum'' is the type species for the genus ''Euphorbia''. It was first described by Carl Linnaeus in 1753 in ''Species Plantarum''. Some euphorbias are widely available commercially, such as poinsettias at Christmas. Some are commonly cultivated as ornamentals, or collected and highly valued for the aesthetic appearance of their unique floral structures, such as the crown of thorns plant (''Euphorbia milii''). ...

Joseph Decaisne
Joseph Decaisne (7 March 1807 – 8 January 1882) was a French botanist and agronomist. He became an ''aide-naturaliste'' to Adrien-Henri de Jussieu (1797-1853), who served as the chair of rural botany. It was during this time that he began to study plants brought back by various travelers like those of Victor Jacquemont (1801-1832) from Asia. Decaisne used applied research, most notably on the agronomy of the Rubia tinctorum, madder, the Yam (vegetable), yam and the ramie. He was also interested in algae. Biography Although born in Brussels, Belgium, he exercised his activity exclusively in Paris. He entered in 1824 as a gardener at the ''Muséum national d'histoire naturelle'' (French museum of natural history) and became, in 1832, head of the ''carré des semis'' section. He also worked at the ''Jardin des Plantes'' and collaborated with Asa Gray. In 1847 he chaired Statistical Agriculture department in the College de France. In 1850, Decaisne followed Charles-François Brisse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomi ...

Stephan Endlicher
Stephan Ladislaus Endlicher also known as Endlicher István László (24 June 1804, Bratislava (Pozsony) – 28 March 1849, Vienna) was an Austrian botanist, numismatist and Sinologist. He was a director of the Botanical Garden of Vienna. Biography Endlicher studied theology and received minor orders. In 1828 he was appointed to the Austrian National Library to reorganize its manuscript collection. Concurrently he studied natural history, in particular botany, and East-Asian languages.

Paraphyletic
In taxonomy (general), taxonomy, a group is paraphyletic if it consists of the group's most recent common ancestor, last common ancestor and most of its descendants, excluding a few Monophyly, monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of Synapomorphy and apomorphy, synapomorphies and symplesiomorphy, symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia (reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
