Nardostachys Jatamansi
''Nardostachys'' is a genus of flowering plant in the honeysuckle family (Caprifoliaceae). ''Nardostachys jatamansi'' is the sole species in genus. It is a perennial that grows in the Himalayas, primarily in a belt through Kumaon, Nepal, Sikkim and Bhutan at elevations of , and in northern Myanmar and western and central China. It is a source of a type of intensely aromatic amber-colored essential oil, spikenard. The oil has, since ancient times, been used as a perfume, as a traditional medicine, and in religious ceremonies. It is also called spikenard, nard, nardin, or muskroot. It is considered endangered due to overharvesting for folk medicine, overgrazing, loss of habitats, and forest degradation. Description The plant grows in height and has pink, bell-shaped flowers. Rhizomes (underground stems) can be crushed and distilled into an intensely aromatic amber-colored essential oil, which is very thick in consistency. Nard oil is used as a perfume, an incense, a sedative, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss people, Swiss botany, botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. De Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perfume
Perfume (, ) is a mixture of fragrance, fragrant essential oils or aroma compounds (fragrances), Fixative (perfumery), fixatives and solvents, usually in liquid form, used to give the human body, animals, food, objects, and living-spaces an agreeable scent. Perfumes can be defined as substances that emit and diffuse a pleasant and fragrant odor. They consist of artificial mixtures of aromatic chemicals and essential oils. The 1939 List of Nobel laureates, Nobel Laureate for Chemistry, Leopold Ružička stated in 1945 that "right from the earliest days of scientific chemistry up to the present time, perfumes have substantially contributed to the development of organic chemistry as regards methods, systematic classification, and theory." Ancient texts and archaeological excavations show the use of perfumes in some of the earliest human civilizations. Modern perfumery began in the late 19th century with the commercial synthesis of aroma compounds such as vanillin and coumarin, whic ...

Monotypic Asterid Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Caprifoliaceae Genera
The Caprifoliaceae or honeysuckle family is a clade of dicotyledonous flowering plants consisting of about 860 species in 33 to 42 genera, with a nearly cosmopolitan distribution. Centres of diversity are found in eastern North America and eastern Asia, while they are absent in tropical and southern Africa. Description The flowering plants in this clade are mostly shrubs and vines: rarely herbs. They include some ornamental garden plants grown in temperate regions. The leaves are mostly opposite with no stipules (appendages at the base of a leafstalk or petiole), and may be either evergreen or deciduous. The flowers are tubular funnel-shaped or bell-like, usually with five outward spreading lobes or points, and are often fragrant. They usually form a small calyx with small bracts. The fruit is in most cases a berry or a drupe. The genera ''Diervilla'' and ''Weigela'' have capsular fruit, while ''Heptacodium'' has an achene. Taxonomy Views of the family-level classificat ...
