Isaac Bayley Balfour
Sir Isaac Bayley Balfour, KBE, FRS, FRSE (31 March 1853 – 30 November 1922) was a Scottish botanist. He was Regius Professor of Botany at the University of Glasgow from 1879 to 1885, Sherardian Professor of Botany at the University of Oxford from 1884 to 1888, and Professor of Botany at the University of Edinburgh from 1888 to 1922. Early life He was the son of John Hutton Balfour, also a botanist, and Marion Spottiswood Bayley, and was born at home, 27 Inverleith Row, Edinburgh. His mother was granddaughter of George Husband Baird. He was the cousin of Sir James Crichton-Browne. Biography Balfour was educated at the Edinburgh Academy from 1864 to 1870. At this early stage his interests and abilities were in the biological sciences, which were taught to him by his father. Due to his father's post as Professor of Botany at Edinburgh, the young Balfour was able to visit the Edinburgh Botanical Gardens, not open to the public at the time. Balfour studied at the University ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ostryopsis
''Ostryopsis'' is a small genus of deciduous shrubs belonging to the birch family Betulaceae. The species have no common English name, though hazel-hornbeam has been suggested, reflecting their similarities to the closely related hazels and hop-hornbeams. The genus is native to China. They are shrubs reaching 3–5 m tall, with alternate, double-toothed hazel-like leaves 2–7 cm long. The flowers are produced in spring, with separate male and female catkins. The fruit form in clusters 3–5 cm long with 6-10 seeds; each seed is a small nut 4–6 mm long, fully enclosed in a sheath-like involucre. The local people in Northeast China has found hazelnuts of '' Ostryopsis davidiana'' and '' Corylus mandshurica'' are more delicious than that of common hazel ''Corylus avellana'', the common hazel, is a species of flowering plant in the birch family Betulaceae. It is native to Europe and western Asia. It is an important component of the hedgerows that were the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diarylheptanoid
The diarylheptanoids (also known as diphenylheptanoids) are a relatively small class of plant secondary metabolites. Diarylheptanoids consist of two aromatic rings (aryl groups) joined by a seven carbons chain (heptane) and having various substituents. They can be classified into linear (curcuminoids) and cyclic diarylheptanoids. The best known member is curcumin, which is isolated from turmeric (''Curcuma longa'') and is known as food coloring E100. Some other ''Curcuma'' species, such as ''Curcuma comosa'' also produce diarylheptanoids. They have been reported from plants in 10 different families, e.g. ''Betulaceae'' and ''Zingiberaceae''. A diarylheptanoid is an intermediate in the biosynthesis of phenylphenalenones in '' Anigozanthos preissii'' or '' Wachendorfia thyrsiflora'' (Haemodoraceae). Cyclic diarylheptanoids Cyclic diarylheptanoids formed from myricanone can be isolated from the bark of ''Myrica rubra'' (Myricaceae). Two cyclic diarylheptanoids, named ostryopsitr ...

Betulaceae
Betulaceae, the birch family, includes six genera of deciduous nut-bearing trees and shrubs, including the birches, alders, hazels, hornbeams, hazel-hornbeam, and hop-hornbeams numbering a total of 167 species. They are mostly natives of the temperate Northern Hemisphere, with a few species reaching the Southern Hemisphere in the Andes in South America. Their typical flowers are catkins and often appear before leaves. In the past, the family was often divided into two families, Betulaceae (''Alnus'', ''Betula'') and Corylaceae (the rest). Recent treatments, including the Angiosperm Phylogeny Group, have described these two groups as subfamilies within an expanded Betulaceae: Betuloideae and Coryloideae. Betulaceae flowers are monoecious, meaning that they have both male and female flowers on the same tree. Their flowers present as catkins and are small and inconspicuous, often with reduced perianth parts. These flowers have large feathery stamen and produce a high volume of ...

Flora Of Sichuan
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 Phyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Described In 1914
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...

Taxa Named By Isaac Bayley Balfour
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
