Pomatosace
''Androsace filicula'' is a species of flowering plant in the family Primulaceae, which was previously placed in its own genus, ''Pomatosace'', endemic to the Qinghai–Tibetan Plateau in China. Description ''Androsace filicula'' is a biennial plant that grows from rosettes of basal leaves, each long and wide and divided into lobes along its length; the leaves may be reminiscent of a fern, providing the species' epithet, ' (diminutive of Latin ', "fern"). The flowers are borne in umbels of 3–12 flowers on a stalk tall. Each flower is white, with five petals fused into a tube for around . Seeds are produced in a capsule, which is approximately wide. Distribution and ecology ''Androsace filicula'' is only found in the north-eastern part of the Qinghai–Tibetan Plateau, in the Chinese provinces of Sichuan, Xizang (Tibet) and Qinghai. It grows in a variety of habitats, including alpine meadows and sand flats along rivers, at altitudes of . It flowers from May to June, and ...

Primulaceae
The Primulaceae ( ), commonly known as the primrose family (but not related to the Onagraceae, evening primrose family), are a family (biology), family of Herbaceous plant, herbaceous and woody flowering plants including some favourite garden plants and wildflowers. Most are Perennial plant, perennial though some species, such as Anagallis arvensis, scarlet pimpernel, are annual plant, annuals. Previously one of three families in the Order (biology), order Primulales, it underwent considerable genus, generic re-alignment once molecular phylogenetic methods were used for taxonomic classification. The order was then submerged in a much enlarged order Ericales and became a greatly enlarged Primulaceae ''sensu lato'' (''s.l''). In this new classification of the Angiosperm Phylogeny Group, each of the Primulales families was reduced to the rank of subfamily of Primulaceae ''s.l.'' The original Primulaceae (Primulaceae ''sensu stricto'' or ''s.s.'') then became subfamily Primuloideae, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Androsace
''Androsace'', commonly known as rock jasmine, is a genus of flowering plants in the family (biology), family Primulaceae, second only to ''Primula'' in the number of species. It is predominantly Arctic–alpine, with many species in the Himalayas (where the genus originated), the mountains of central Asia, the Caucasus, and the southern and central European mountain systems, particularly the Alps and the Pyrenees. Plants of this genus are sometimes known as rock jasmines or fairy candelabras, and are widely cultivated for their dense cushions covered in white or pink flowers. There are roughly 110 species. These plants have small entire or toothed leaves which form a basal rosette. Taxonomy Recent molecular studies show that the genera ''Douglasia'' (found in north-western North America and easternmost Siberia), ''Pomatosace'' (an Himalayan endemic) and ''Vitaliana'' (a European endemic (ecology), endemic) are nested within ''Androsace''. Phylogenetic studies have also demonst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karl Maximovich
Carl Johann Maximovich, also Karl Ivanovich Maximovich (Russian language, Russian: Карл Иванович Максимович; 23 November 1827 – 16 February 1891) was a Russian botanist. Maximovich spent most of his life studying the flora of the countries he had visited in the Far East, and naming many new species. He worked at the Saint Petersburg Botanical Gardens from 1852 as curator of the herbarium collection, becoming Director in 1869. History Born a Baltic-German, his name at birth was Karl Ivanovich Maksimovich, but he changed it to the German (language), German version of his name for his scientific work.Japan’s botanical sunrise plant exploration around the Meiji Restoration Peter Barnes (originally published in Curtis's Botanical Magazine 18(1): ...

Missouri Botanical Garden Press
The Missouri Botanical Garden is a botanical garden located at 4344 Shaw Boulevard in St. Louis, Missouri. It is also known informally as Shaw's Garden for founder and philanthropist Henry Shaw. Its herbarium, with more than 6.6 million specimens, is the second largest in North America, behind that of the New York Botanical Garden. Its Peter H. Raven Library contains 85% coverage of all literature ever published on systematic botany and plant taxonomy. The ''Index Herbariorum'' code assigned to the herbarium is MO and it is used when citing housed specimens. History The land that is currently the Missouri Botanical Garden was previously the land of businessman Henry Shaw. Founded in 1859, the Missouri Botanical Garden is one of the oldest botanical institutions in the United States and a National Historic Landmark. It is also listed in the National Register of Historic Places. In 1983, the botanical garden was added as the fourth subdistrict of the Metropolitan Zoologi ...

Systematic Biology
Systematics is the study of the diversification of living forms, both past and present, and the relationships among living things through time. Relationships are visualized as evolutionary trees (synonyms: phylogenetic trees, phylogenies). Phylogenies have two components: branching order (showing group relationships, graphically represented in cladograms) and branch length (showing amount of evolution). Phylogenetic trees of species and higher taxa are used to study the evolution of traits (e.g., anatomical or molecular characteristics) and the distribution of organisms (biogeography). Systematics, in other words, is used to understand the evolutionary history of life on Earth. The word systematics is derived from the Latin word of Ancient Greek origin '' systema,'' which means systematic arrangement of organisms. Carl Linnaeus used 'Systema Naturae' as the title of his book. Branches and applications In the study of biological systematics, researchers use the different branch ...

Monophyly
In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most recent common ancestor (or more precisely an ancestral population), i.e. excludes non-descendants of that common ancestor # the grouping contains all the descendants of that common ancestor, without exception Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic'' grouping meets 1. but not 2., thus consisting of the descendants of a common ancestor, excepting one or more monophyletic subgroups. A ''polyphyletic'' grouping meets neither criterion, and instead serves to characterize convergent relationships of biological features rather than genetic relationships – for example, night-active primates, fruit trees, or aquatic insects. As such, these characteristic features of a polyphyletic grouping are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetics, phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in Taxonomy (biology), taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tre ...

Qinghai Province
Qinghai is an inland province in Northwestern China. It is the largest province of China (excluding autonomous regions) by area and has the third smallest population. Its capital and largest city is Xining. Qinghai borders Gansu on the northeast, Xinjiang on the northwest, Sichuan on the southeast and the Tibet Autonomous Region on the southwest. Qinghai province was established in 1928 during the period of the Republic of China, and until 1949 was ruled by Chinese Muslim warlords known as the Ma clique. The Chinese name "Qinghai" is after Qinghai Lake, the largest lake in China. The lake is known as Tso ngon in Tibetan, and as Kokonor Lake in English, derived from the Mongol Oirat name for Qinghai Lake. Both Tso ngon and Kokonor are names found in historic documents to describe the region.Gangchen Khishong, 2001.
