Pentaphylax
''Pentaphylax'' is a genus of flowering plants, with one or two species which are shrubs and small trees. The species has simple evergreen leaves that are alternately arranged on the stems. The flower pistil is 5 celled and the anthers dehiscing via pores and basifixed. Flowers have five petals and five sepals that are distinct from each other and five stamens attached oppositely to the sepals. The seeds are winged. Native from Tropical areas of South China to Malay Peninsula and Sumatra. Species include: *'' Pentaphylax euryoides'' Taxonomy The APG III system of 2009 places the genus in the family Pentaphylacaceae, along with genera formerly placed in the Ternstroemiaceae. ''Pentaphylax'' has often been placed in its own family, the Pentaphylacaceae, separated from the Theaceae or Ternstroemiaceae based on the structure of the anthers and, arguably, the ovules. However, some molecular data and curved embryos (typical of the Ternstroemiaceae) point to a close relationship wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentaphylax Euryoides
''Pentaphylax euryoides'' () is a species of flowering plant in the Pentaphylacaceae family that can in be found on Sumatra and in such countries as Malaysia, Vietnam and China. In China, it is found in such provinces as Guangdong, Guangxi, Guizhou, Hainan, Yunnan, and in southern parts of Fujian, Hunan, and Jiangxi. Description The species is tall with its petioles being long. The leaf-blades are lanceolate, oblong, ovate and are long by wide. Pedicels are and carry triangular shaped bracteoles which are as long as the petiole. It also have five sepals that are long and orbicular. ''P. euryoides'' have five stamens which are and are oblong. The seed A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiospe ...s are reddish-brown in colour and are long.

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] |
Flora Of China (series)
''Flora of China'' is a scientific publication aimed at describing the plants native to China. The project is a collaborative scientific effort to publish the first modern English-language account of the 31,000 species of vascular plants of China. This number includes about 8,000 species of medicinal and economically important plants and about 7,500 species of trees and shrubs. ''Flora of China'' describes and otherwise documents these species. ''Flora of China'' is an English-language revision of (FRPS), with taxonomy reflecting the current understanding of each group. The sequence of families is a modified Englerian system, similar to that used in FRPS; however, the circumscription of some families reflects the present understanding of the groups. It is intended that all the vascular plants of China will be covered, including descriptions, identification keys, essential synonymy, phenology, provincial distribution in China, brief statements on extra-Chinese distribution, an ...

APG III System
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system. Along with the publication outlining the new system, there were two accompanying publications in the same issue of the Botanical Journal of the Linnean Society: * The first, by Chase & Reveal, was a formal phylogenetic classification of all land plants (embryophytes), compatible with the APG III classification. As the APG have chosen to eschew ranks above order, this paper was meant to fit the system into the existing Linnaean hierarchy for those that prefer such a classification. The result was that all land plants were placed in the class Equisetopsida, which was then divided into 16 subclasses and a multitude of superorders. * The second, by Haston ''et al.'', was a linear sequence of families followi ...

Theaceae
Theaceae (), the tea family, is a family (biology), family of flowering plants comprising shrubs and trees, including the economically important tea plant, and the ornamental camellias. It can be described as having from seven to 40 genus, genera, depending on the source and the method of circumscription used. The family Ternstroemiaceae has been included within Theaceae;Royal Botanic Gardens, Kew. ''Vascular Plant Families and Genera''TheaceaeWatson, L., & Dallwitz, M. J. (1992 onwards). ''The families of flowering plants''/ref> however, the APG III system of 2009 places it instead in Pentaphylacaceae. Most but not all species are native species, native to China and East Asia. Family traits Plants in this family are characterized by simple leaves that are alternate spiral to distichial, serrated, and usually glossy. Most of the genera have evergreen foliage, but ''Stewartia'' and ''Franklinia'' are deciduous. The toothed margins are generally associated with a characteristic T ...

American Journal Of Botany
The ''American Journal of Botany'' is a monthly peer-reviewed scientific journal which covers all aspects of plant biology. It has been published by the Botanical Society of America since 1914. The journal has an impact factor of 3.038, as of 2019. As of 2018, access is available through the publisher John Wiley & Sons (Wiley). From 1951 to 1953, Oswald Tippo served as its editor; the current editor is Pamela Diggle. History In the early 20th century, the field of botany was rapidly expanding, but the publications in which botanists could publish remained limited and heavily backlogged. By 1905, it was estimated that 250,000 contributions were generated in 8 or 9 languages. At the 1911 annual meeting of the society in Washington D.C., it was noted that at least 300 pages of American botanical contributions were sent abroad for publication, with a backlog resulting in a one-year delay in publication. On 31 December 1907, the Botanical Society of America met in Chicago and formal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Botanist
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

Rolf Dahlgren
Rolf Martin Theodor Dahlgren (7 July 1932 – 14 February 1987) was a Swedish-Danish botanist and professor at the University of Copenhagen from 1973 to his death. Life Dahlgren was born in Örebro on 7 July 1932 to apothecary Rudolf Dahlgren and wife Greta née Dahlstrand. He took his MSc degree in Biology in (1955) and PhD degree in Botany in (1963) at Lund University. He was killed in a car crash in Scania, Sweden on 14 February 1987. Career He continued working on South African plants during expeditions in 1956-57 and 1965–66, while affiliated with the ''Botanical Museum'' in Lund as ''docent''. In 1973, he became professor of botany at the University of Copenhagen. Here, he developed his system of Angiosperm classification, based on many more characters simultaneously than previous systems, most notably many chemical plant traits (see also chemotaxonomy). Although the system was first presented in Danish, it rapidly gained widespread acceptance, particularly due to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cronquist System
The Cronquist system is a taxonomic classification system of flowering plants. It was developed by Arthur Cronquist in a series of monographs and texts, including ''The Evolution and Classification of Flowering Plants'' (1968; 2nd edition, 1988) and ''An Integrated System of Classification of Flowering Plants'' (1981) (''see'' Bibliography). Cronquist's system places flowering plants into two broad classes, Magnoliopsida ( dicotyledons) and Liliopsida (monocotyledons). Within these classes, related orders are grouped into subclasses. While the scheme was widely used, in either the original form or in adapted versions, many botanists now use the Angiosperm Phylogeny Group classification for the orders and families of flowering plants, first developed in 1998. The system as laid out in Cronquist's ''An Integrated System of Classification of Flowering Plants'' (1981) counts 64 orders and 321 families in class Magnoliopsida and 19 orders and 65 families in class Liliopsida.
