Xanthorhiza Simplicissima
''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 ...

Humphry Marshall (October 10, 1722 – November 5, 1801) was an American botanist and plant dealer.

Plant Stem
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue. The stem can also be called halm or haulm. The stem is normally divided into nodes and internodes: * The nodes hold one or more leaves, as well as buds which can grow into branches (with leaves, conifer cones, or flowers). Adventitious roots may also be produced from the nodes. * The internodes distance one node from another. The term "shoots" is often confused with "stems"; "shoots" generally refers to new fresh plant growth including both stems and other structures like leaves or flowers. In most plants stems are located above the soil surface but some plants have underground stems. Stems have four main functions which are: * Support for and the elevation of leaves, flowers, and fruits. The stems ke ... [...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. Planted in the heyday of Victorian plant hunting in the mid-19th century as part of the Westonbirt House estate, the arboretum forms part of a site which is listed Grade I on the Register of Historic Parks and Gardens of special historic interest.

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] |

Sexual Reproduction
Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete ( haploid reproductive cells, such as a sperm or egg cell) with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes ( diploid). This is typical in animals, though the number of chromosome sets and how that number changes in sexual reproduction varies, especially among plants, fungi, and other eukaryotes. Sexual reproduction is the most common life cycle in multicellular eukaryotes, such as animals, fungi and plants. Sexual reproduction also occurs in some unicellular eukaryotes. Sexual reproduction does not occur in prokaryotes, unicellular organisms without cell nuclei, such bacteria and archaea. However, some process in bacteria may be considered analogous to sexual reproduction in that they incorporate new genetic information, including bacterial conjugation, transformatio ...
