Ranzania (plant)
is a monotypic genus of perennial herbs in the family Berberidaceae, the only species is ''Ranzania japonica''. It is native to woodlands in the mountains of Honshu, Japan. This genus is named in honor of Ono Ranzan, who has been called "the Japanese Linnaeus". Fleshy stems of ''Ranzania'' form small colonies from an underground rhizome. Each stem bears two trifoliate compound leaves, and between the leaves is a single or more commonly a small cluster of drooping cup-shaped mauve flowers. These develop into an upright clusters of white berries. The haploid chromosome number is ''n''=7. Uses It is occasionally used in shade gardens in the west.

Monotypic
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. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

Honshu
, historically called , is the largest and most populous island of Japan. It is located south of Hokkaidō across the Tsugaru Strait, north of Shikoku across the Inland Sea, and northeast of Kyūshū across the Kanmon Straits. The island separates the Sea of Japan, which lies to its north and west, from the North Pacific Ocean to the south and east. It is the seventh-largest island in the world, and the second-most populous after the Indonesian island of Java. Honshu had a population of 104 million , constituting 81.3% of the entire population of Japan, and is mostly concentrated in the coastal areas and plains. Approximately 30% of the total population resides in the Greater Tokyo Area on the Kantō Plain. As the historical center of Japanese cultural and political power, the island includes several past Japanese capitals, including Kyōto, Nara and Kamakura. Much of the island's southern shore forms part of the Taiheiyō Belt, a megalopolis that spans several of the Japane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ono Ranzan
, also known as , was a Japanese botany, botanist and herbalism, herbalist, known as the "Japanese Carl Linnaeus, Linnaeus". Ono's real surname was ; his adult given name was . became his art name and his Chinese style courtesy name. He was born in Kyoto to a courtly family, and studied in his youth under Matsuoka Shoan. In 1754, he opened a school of botanical pharmacology (pharmacognosy) which enjoyed considerable success, with over a thousand pupils enrolling. One student who studied under Ono at this time was Kimura Kenkadō. In 1799, he was given a post at the Seijūkan, the country's major government medical school in Edo. Here he worked extensively on a translation into Japanese of Rembert Dodoens' herbal guide, the ''Cruydeboeck''. Ono was familiar with Western herbalism (making use of the work of Johann Wilhelm Weinmann in his translation) and had studied both traditional Chinese medicine and Western medicine as well. Some of Ono's own works on Japanese botany were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhizome
In botany and dendrology, a rhizome (; , ) is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs underground horizontally. A stolon is similar to a rhizome, but a stolon sprouts from an existing stem, has long internodes, and generates new shoots at the end, such as in the strawberry plant. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. In general, a tuber is high in starch, e.g. the potato, which is a modified stolon. The term "tuber" is often used imprecisely and is sometimes applied to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compound Leaves
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower (abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light e ...

Chromosome
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated ( S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now called si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shade Garden
Shade gardens are a type of garden planted and grown in areas with little or no direct sunlight. Shade gardens may occur naturally or by design under trees, as well as on the side of buildings or fences. This style of garden presents certain challenges, in part because only certain plants are able to grow in shady conditions and otherwise there is direct competition for sunlight. Very few edible plants grow well in shady conditions, so shade gardens are usually ornamental gardens, though growing flowers may also be difficult in shade. Light shade, also known as "dappled sunlight", may support growing herbs or some leaf vegetables, but in addition to lack of light, trees and other large plants which create shade gardens may negatively impact soil fertility. See also * List of garden types A wide range of garden types exist. Below is a list of examples. By country of origin *Chinese garden ** Cantonese garden ** Sichuanese garden *Dutch garden * Egyptian garden *Eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Podophyllum
''Podophyllum'' is a genus of flowering plant in the family Berberidaceae, native from Afghanistan to China, and from southeast Canada to the central and eastern United States. The genus was first described by Carl Linnaeus in 1753. Taxonomy The taxonomic status of the genus has varied. Some sources transferred all but ''Podophyllum peltatum'' to other genera, such as ''Dysosma'' and ''Sinopodophyllum''. , Plants of the World Online regarded these genera as synonyms of ''Podophyllum''. Species , Plants of the World Online accepted the following species: *''Podophyllum aurantiocaule'' Hand.-Mazz. *''Podophyllum cymosum'' (Michx.)
