Karl Heinrich Emil Koch
Karl Heinrich Emil Koch (6 June 1809 – 25 May 1879) was a German botanist. He is best known for his botanical explorations in the Caucasus region, including northeast Turkey. Most of his collections have today been lost. He is also known as the first professional horticultural officer in Germany. Biography He was born in Ettersburg near Weimar, Germany. He studied at the universities of Jena and Würzburg and taught, as privatdocent, at the University of Jena beginning 1834. He became an associate professor in 1836. He undertook a journey of research into southern Russia in 1836–38, and a second in 1843–44. The fruit of this second trip, in which he also visited Asia Minor, Great Armenia, the Caspian Sea, and the Caucasus Mountains,ADB:Koch, Karl In: |
Holodiscus Microphyllus
''Holodiscus discolor'', commonly known as ocean spray or oceanspray, creambush, or ironwood, is a shrub of western North America. Description ''Holodiscus discolor'' is a fast-growing deciduous shrub usually from to in height, and up to tall. Its alternate leaves are small, long and broad, lobed, juicy green when new. The young branches have longitudinal ridges. Cascading clusters of white flowers drooping from the branches give the plant its two common names. The flowers have a faint sweet, sugary scent. The bloom period is May to July. It bears a small, hairy fruit containing one seed which is light enough to be dispersed by wind. Distribution and habitat The plant is common in the Pacific Northwest, and throughout California in diverse habitats including California mixed evergreen forest, California oak woodlands, chaparral, Coast redwood forest, Douglas-fir forest, Yellow pine forest, Red fir forest, and Lodgepole pine forest. It is native to regions of Califor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Western Canada
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] |

Rosaceae Genera
Rosaceae (), the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus ''Rosa''. Among the most species-rich genera are ''Alchemilla'' (270), ''Sorbus'' (260), '' Crataegus'' (260), ''Cotoneaster'' (260), ''Rubus'' (250), and ''Prunus'' (200), which contains the plums, cherries, peaches, apricots, and almonds. However, all of these numbers should be seen as estimates—much taxonomic work remains. The family Rosaceae includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere. Many economically important products come from the Rosaceae, including various edible fruits, such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, Blackberry, blackberries, loquats, strawberries, rose hips, Crataegus, hawthorns, and almonds. The family also includes popular ornamental ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amygdaloideae
Amygdaloideae is a subfamily within the flowering plant family Rosaceae. It was formerly considered by some authors to be separate from Rosaceae, and the family names Prunaceae and Amygdalaceae have been used. Reanalysis from 2007 has shown that the previous definition of subfamily Spiraeoideae was paraphyletic. To solve this problem, a larger subfamily was defined that includes the former Amygdaloideae, Spiraeoideae, and Maloideae. This subfamily, however, is to be called Amygdaloideae rather than Spiraeoideae under the International Code of Nomenclature for algae, fungi, and plants as updated in 2011. As traditionally defined, the Amygdaloideae includes such commercially important crops as plum, cherry, apricot, peach, and almond. The fruit of these plants are known as stone fruit ( drupes), as each fruit contains a hard shell (the endocarp) called a ''stone'' or ''pit'', which contains the single seed. The expanded definition of the Amygdaloideae adds to these commerci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Biology
Molecular biology is the branch of biology that seeks to understand the molecular basis of biological activity in and between cells, including biomolecular synthesis, modification, mechanisms, and interactions. The study of chemical and physical structure of biological macromolecules is known as molecular biology. Molecular biology was first described as an approach focused on the underpinnings of biological phenomena - uncovering the structures of biological molecules as well as their interactions, and how these interactions explain observations of classical biology. In 1945 the term molecular biology was used by physicist William Astbury. In 1953 Francis Crick, James Watson, Rosalind Franklin, and colleagues, working at Medical Research Council unit, Cavendish laboratory, Cambridge (now the MRC Laboratory of Molecular Biology), made a double helix model of DNA which changed the entire research scenario. They proposed the DNA structure based on previous research done by Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maloideae
The Maloideae C.Weber was the apple subfamily, a grouping used by some taxonomists within the rose family, Rosaceae. Recent molecular phylogenetic evidence has shown that the traditional Spiraeoideae and Amygdaloideae form part of the same clade as the traditional Maloideae, and the correct name for this group is Amygdaloideae. Earlier circumscriptions of Maloideae are more-or-less equivalent to subtribe Malinae or to tribe Maleae. The group includes a number of plants bearing commercially important fruits, such as apples and pears, while others are cultivated as ornamentals. In its traditional circumscriptionG. K.
