Ribes Triste
''Ribes triste'', known as the northern redcurrant, swamp redcurrant, or wild redcurrant, is an Asian and North American shrub in the gooseberry family. It is widespread across Canada and the northern United States, as well as in eastern Asia (Russia, China, Korea, Japan). ''Ribes triste'' grows in wet rocky woods, swamps, and cliffs. It grows to tall, with a lax, often creeping branches. The leaves are alternate, palmately lobed with five lobes, in diameter. The flowers are in pendulous racemes, long. The axis of the raceme is glandular. Each raceme bears 6-13 small, purplish flowers that appear in June and July. The fruit is a bright red berry, without the hairs that some currants have. The fruit is edible but rather sour. Conservation status in the United States It is listed as endangered in Connecticut and Ohio, and as threatened in Pennsylvania. As a weed Ribes is listed a plant pest in Michigan and the planting of it in certain parts of the state is prohibited. U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peter Simon Pallas
Peter Simon Pallas Fellow of the Royal Society, FRS FRSE (22 September 1741 – 8 September 1811) was a Prussian zoologist and botanist who worked in Russia between 1767 and 1810. Life and work Peter Simon Pallas was born in Berlin, the son of Professor of Surgery Simon Pallas. He studied with private tutors and took an interest in natural history, later attending the University of Halle and the University of Göttingen. In 1760, he moved to the University of Leiden and passed his doctor's degree at the age of 19. Pallas travelled throughout the Netherlands and to London, improving his medical and surgical knowledge. He then settled at The Hague, and his new system of animal classification was praised by Georges Cuvier. Pallas wrote ''Miscellanea Zoologica'' (1766), which included descriptions of several vertebrates new to science which he had discovered in the Dutch museum collections. A planned voyage to southern Africa and the East Indies fell through when his father reca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viburnum Trilobum
''Viburnum trilobum'' (cranberrybush viburnum, American cranberrybush, high bush cranberry, or highbush cranberry) is a species of '' Viburnum'' native to northern North America, from Newfoundland west to British Columbia, south to Washington state and east to northern Virginia. It is very closely related to the European and Asian '' Viburnum opulus'', and is often treated as a variety of it, as ''Viburnum opulus'' L. var. ''americanum'' Ait., or as a subspecies, '' Viburnum opulus'' subsp. ''trilobum'' (Marshall) Clausen. Description It is a deciduous shrub growing to tall. The bark is gray and rough and has a scaly texture. The stems arch and are very dense, and the twigs are a reddish-brown color. The leaves are opposite, three-lobed, long and broad, with a rounded base and serrated margins; they are superficially similar to many maple leaves, most easily distinguished by their somewhat wrinkled surface with impressed leaf venation. The leaf buds are green. The bud scale ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Food Plants
Bird food plants are certain trees, shrubs and herbaceous plants bearing fruits which afford food for birds. These have been discovered by observation, and by the scientific examination of the contents of birds' stomachs. By planting those species, therefore, which have been proved most desirable and that are suited to the climate and soil of the chosen location, birds can be attracted to the vicinity of dwelling houses or to any other desired spot as a copse or shrubbery, or, on the other hand, lured away from valuable orchards, since they appear to like best arid, bitter, sour or aromatic fruits, distasteful to human beings, even better than the cultivated kinds. Many of these bird-attracting plants are ornamental as well, since many have pretty fruits, red in color and often clinging to their branches far into the winter, furnishing grateful additions to the meager fare of hard-weather birds.

Plants Used In Traditional Native American Medicine
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the abilit ...

Flora Of Siberia
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 Phy ... [...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] |

Kidney Stones
Kidney stone disease, also known as nephrolithiasis or urolithiasis, is a crystallopathy where a solid piece of material (kidney stone) develops in the urinary tract. Kidney stones typically form in the kidney and leave the body in the urine stream. A small stone may pass without causing symptoms. If a stone grows to more than , it can cause blockage of the ureter, resulting in sharp and severe pain in the lower back or abdomen. A stone may also result in blood in the urine, vomiting, or painful urination. About half of people who have had a kidney stone will have another within ten years. Most stones form by a combination of genetics and environmental factors. Risk factors include high urine calcium levels, obesity, certain foods, some medications, calcium supplements, hyperparathyroidism, gout and not drinking enough fluids. Stones form in the kidney when minerals in urine are at high concentration. The diagnosis is usually based on symptoms, urine testing, and medical ...

Decoction
Decoction is a method of extraction by boiling herbal or plant material (which may include stems, roots, bark and rhizomes) to dissolve the chemicals of the material. It is the most common preparation method in various herbal-medicine systems. Decoction involves first drying the plant material; then mashing, slicing, or cutting the material to allow for maximum dissolution; and finally boiling in water to extract oils, volatile organic compounds and other various chemical substances. Occasionally, aqueous ethanol or glycerol may be used instead of water. Decoction can be used to make tisanes, tinctures and similar solutions. Decoctions and infusions may produce liquids with differing chemical properties, as the temperature or preparation difference may result in more oil-soluble chemicals in decoctions versus infusions. The process can also be applied to meats and vegetables to prepare bouillon or stock, though the term is typically only used to describe boiled plant extracts, usua ...

Upper Tanana
Upper Tanana (also known as Tabesna, Nabesna or Nee'aanèegn') is an endangered Athabaskan language spoken in eastern Interior Alaska, United States, mainly in the villages of Northway, Tetlin, and Tok, and adjacent areas of the Canadian territory of Yukon. In 2000 there were fewer than 100 speakers, and the language was no longer being acquired by children. Overview Upper Tanana shows near mutual-intelligibility with neighboring Tanacross but differs in several phonological features. In particular, Upper Tanana has low tone as a reflex of Proto-Athabaskan constriction, where Tanacross has high tone. Upper Tanana also has an extra vowel phoneme and has developed diphthongs through loss of final consonants. Traditionally, five main dialects have been recognized. The main Upper Tanana speaking communities today are located in the Alaskan communities of Northway and Tetlin and in the Canadian community of Beaver Creek.
