Xanthorhiza
''Xanthorhiza simplicissima'' (yellowroot) is the only member of the genus ''Xanthorhiza'', and one of very few genera in the family Ranunculaceae with a woody stem (the other notable example being ''Clematis''). It is native to the eastern United States from Maine south to northern Florida and west to Ohio and eastern Texas. It contains the alkaloid berberine, which has a number of traditional and contemporary uses for dyeing and medicine. The genus name as well as the common name refer to the plant's yellow roots (''xantho-'' meaning "yellow" and ''rhiza'' meaning "root"), which was used to produce a yellow dye by Native Americans. The specific epithet refers to the simple (not branched) stems. In the wild, it grows on the edges of streams in sandy soil under a canopy of dappled sunlight. In cultivation, it is often provided with more sunlight so that the fall colors are more vivid. It is a subshrub, reaching (rarely ) in height, with stems up to diameter. The leaves are s ...

Ranunculaceae
Ranunculaceae (buttercup or crowfoot family; Latin "little frog", from "frog") is a family of over 2,000 known species of flowering plants in 43 genera, distributed worldwide. The largest genera are ''Ranunculus'' (600 species), ''Delphinium'' (365), ''Thalictrum'' (330), ''Clematis'' (325), and ''Aconitum'' (300). Description Ranunculaceae are mostly herbaceous annuals or perennials, but some are woody climbers (such as ''Clematis'') or shrubs (e.g. ''Xanthorhiza''). Most members of the family have bisexual flowers which can be showy or inconspicuous. Flowers are solitary, but are also found aggregated in cymes, panicles, or spikes. The flowers are usually radially symmetrical but are also found to be bilaterally symmetrical in the genera ''Aconitum'' and ''Delphinium''. The sepals, petals, stamens and carpels are all generally free (not fused), the outer flower segments typically number four or five. The outer stamens may be modified to produce only nectar, as in Aqui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berberine
Berberine is a quaternary ammonium salt from the protoberberine group of benzylisoquinoline alkaloids found in such plants as ''Berberis vulgaris'' (barberry), ''Berberis aristata'' (tree turmeric), ''Mahonia aquifolium'' (Oregon grape), ''Hydrastis canadensis'' (goldenseal), ''Xanthorhiza simplicissima'' (yellowroot), ''Phellodendron amurense'' (Amur cork tree), ''Coptis chinensis'' (Chinese goldthread), ''Tinospora cordifolia'', ''Argemone mexicana'' (prickly poppy), and ''Eschscholzia californica'' (Californian poppy). Berberine is usually found in the roots, rhizomes, stems, and bark. Due to its yellow color, ''Berberis'' species were used to dye wool, leather, and wood. Under ultraviolet light, berberine shows a strong yellow fluorescence, making it useful in histology for staining heparin in mast cells. As a natural dye, berberine has a color index of 75160. Research and adverse effects The safety of using berberine for any condition is not adequately defined by high-qua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Westonbirt Arboretum
Westonbirt, The National Arboretum is an arboretum in Gloucestershire, England, about southwest of the town of Tetbury. Managed by Forestry England, it is perhaps the most important and widely known arboretum in the United Kingdom.

Berkshire
Berkshire ( ; in the 17th century sometimes spelt phonetically as Barkeshire; abbreviated Berks.) is a historic county in South East England. One of the home counties, Berkshire was recognised by Queen Elizabeth II as the Royal County of Berkshire in 1957 because of the presence of Windsor Castle, and letters patent were issued in 1974. Berkshire is a county of historic origin, a ceremonial county and a non-metropolitan county without a county council. The county town is Reading. The River Thames formed the historic northern boundary, from Buscot in the west to Old Windsor in the east. The historic county, therefore, includes territory that is now administered by the Vale of White Horse and parts of South Oxfordshire in Oxfordshire, but excludes Caversham, Slough and five less populous settlements in the east of the Royal Borough of Windsor and Maidenhead. All the changes mentioned, apart from the change to Caversham, took place in 1974. The towns of Abingdon, Didcot, Far ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
