JeffersonIA MahanayTower
''Jeffersonia'', also known as twinleaf or rheumatism root, is a small genus of herbaceous perennial plants in the family Berberidaceae. They are uncommon spring wildflowers and grow in limestone soils of rich deciduous forests. ''Jeffersonia'' was named for United States President Thomas Jefferson by his contemporary Benjamin Smith Barton. This genus was formerly grouped in genus ''Podophyllum''. Twinleaf is protected by state laws as a threatened or endangered plant in Georgia, Iowa, New York, and New Jersey. Description ''Jeffersonia diphylla'' has leaves and flowers that are smooth and emerge directly from the rhizome. The leaves are divided into two leaflets which are half-ovate in shape with entire or shallowly toothed margins. It has showy white flowers with four sepals, eight petals, eight stamens, and a singly pistil; the flower resembles bloodroot flowers. The short-lived flower appears in April or May before the forest canopy appears (see spring ephemeral). The f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benjamin Smith Barton
Benjamin Smith Barton (February 10, 1766 – December 19, 1815) was an American botanist, naturalist, and physician. He was one of the first professors of natural history in the United States and built the largest collection of botanical specimens in the country. He wrote the first American textbook on botany. Early life Barton's father, Rev. Thomas Barton, was an Irish immigrant from Carrickmacross who opened a school near Norristown, Pennsylvania in 1751. His mother was Esther Rittenhouse, sister of astronomer David Rittenhouse. Between 1780 and 1782, Barton studied at York Academy in Lancaster, Pennsylvania, where he showed an aptitude for drawing and an interest in collecting natural history specimens. Two years later, he attended the College of Philadelphia School of Medicine, studied medicine under Thomas Shippen, and attended Benjamin Rush's lectures in 1785. Young Barton also accompanied his uncle, David Rittenhouse, who had been commissioned to survey the western boun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bloodroot
''Sanguinaria canadensis'', bloodroot, is a Perennial plant, perennial, herbaceous flowering plant native to eastern North America. It is the monotypic genus, only species in the genus ''Sanguinaria'', included in the poppy family Papaveraceae, and is most closely related to ''Eomecon'' of eastern Asia. ''Sanguinaria canadensis'' is sometimes known as Canada puccoon, bloodwort, redroot, red puccoon, and black paste. Plants are variable in leaf and flower shape, and have been separated as a different subspecies due to these variable shapes, indicating a highly variable species. In bloodroot, the juice is red and poisonous. Products made from sanguinaria extracts, such as black salve, are escharotic and can cause permanent disfiguring scar, scarring. Although preliminary studies have suggested that sanguinaria may have potential applications in cancer therapy, clinical studies are lacking, and its use is not recommended.

Alkaloid
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.Chemical Encyclopedia: alkaloids xumuk.ru Alkaloids are produced by a large variety of organisms including , , Medicinal plant, plants, an ...

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] |
Dicentra Canadensis
''Dicentra canadensis'', the squirrel corn, is a flowering plant from eastern North America with oddly shaped white flowers and finely divided leaves. Description Squirrel corn has small yellow clustered bulblets (looking roughly like kernels of maize, corn), finely dissected leaf, leaves, and white heart-shaped flowers. The flowers are fragrant. It is a ephemeral plant, spring ephemeral, leafing out and flowering in spring and going dormancy, dormant in summer. Distribution and habitat It is native to temperate deciduous forest, deciduous woodland in eastern North America. It is also found among rock outcrops near mountains.

Goldenseal
''For the magazine from West Virginia see Goldenseal (magazine)'' Goldenseal (''Hydrastis canadensis''), also called orangeroot or yellow puccoon, is a perennial herb in the buttercup family Ranunculaceae, native to North America. It may be distinguished by its thick, yellow knotted rootstock. The stem is purplish and hairy above ground and yellow below ground where it connects to the yellow rhizome. Goldenseal reproduces both clonally through the rhizome and sexually, with clonal division more frequent than asexual reproduction. It takes between 4 and 5 years for a plant to reach sexual maturity, i.e. the point at which it produces flowers. Plants in the first stage, when the seed erupts and cotyledons emerge, can remain in this state one or more years. The second vegetative stage occurs during years two and three (and sometimes longer) and is characterized by the development of a single leaf and absence of a well developed stem. Finally, the third stage is reproductive, at wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of China
The flora of China consists of a diverse range of plant species including over 39,000 vascular plants, 27,000 species of fungi and 3000 species of bryophytes.Wu, Z. Y., P. H. Raven & D. Y. Hong, eds. 2006. Flora of China. Vol. 22 (Poaceae). Science Press, Beijing, and Missouri Botanical Garden Press, St. Louis More than 30,000 plant species are native to China, representing nearly one-eighth of the world's total plant species, including thousands found nowhere else on Earth. China's land, extending over 9.6 million km, contains a variety of ecosystems and climates for plants to grow in. Some of the main climates include shores, tropical and subtropical forests, deserts, elevated plateaus and mountains. The events of the continental drift and early Paleozoic Caledonian movement also play a part in creating climatic and geographical diversity resulting in high levels of endemic vascular flora. These landscapes provide different ecosystems and climates for plants to grow in, creati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
