''Koenigia weyrichii'' (synonym ''Persicaria weyrichii''), the Chinese knotweed or Weyrich's knotweed, is a large, perennial, rhizomatous herb native to East Asia. It is one of the parents of the cultivated hybrid ''Koenigia'' × ''fennica'', the other being ''Koenigia alpina ''Koenigia alpina'' (synonym ''Aconogonon alpinum''), commonly known as alpine knotweed, is similar to '' Koenigia alaskana'', but differs in leaf size and achene characteristics.

Tanja Schuster
Tanja Magdalena Schuster is a taxonomist from Kaindorf, Austria and the first Pauline Ladiges Plant Systematics Fellow, holding a joint position with the School of Biosciences, University of Melbourne, Victoria, Australia, and the National Herbarium of Victoria, Royal Botanic Gardens Melbourne. Schuster also worked as curator of the Norton-Brown Herbarium at the University of Maryland, College Park. In 2011, Schuster created the genus ''Duma (plant), Duma'' for some species previously placed in ''Muehlenbeckia'', but which were shown by Molecular phylogenetics, molecular phylogenetic studies to form a distinct clade. The name is derived from the Latin for "thorn-bush."

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

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] |
Herb
In general use, herbs are a widely distributed and widespread group of plants, excluding vegetables and other plants consumed for macronutrients, with savory or aromatic properties that are used for flavoring and garnishing food, for medicinal purposes, or for fragrances. Culinary use typically distinguishes herbs from spices. ''Herbs'' generally refers to the leafy green or flowering parts of a plant (either fresh or dried), while ''spices'' are usually dried and produced from other parts of the plant, including seeds, bark, roots and fruits. Herbs have a variety of uses including culinary, medicinal, aromatic and in some cases, spiritual. General usage of the term "herb" differs between culinary herbs and medicinal herbs; in medicinal or spiritual use, any parts of the plant might be considered as "herbs", including leaves, roots, flowers, seeds, root bark, inner bark (and cambium), resin and pericarp. The word "herb" is pronounced in Commonwealth English, but is common am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Asia
East Asia is the eastern region of Asia, which is defined in both geographical and ethno-cultural terms. The modern states of East Asia include China, Japan, Mongolia, North Korea, South Korea, and Taiwan. China, North Korea, South Korea and Taiwan are all unrecognised by at least one other East Asian state due to severe ongoing political tensions in the region, specifically the division of Korea and the political status of Taiwan. Hong Kong and Macau, two small coastal quasi-dependent territories located in the south of China, are officially highly autonomous but are under Chinese sovereignty. Japan, Taiwan, South Korea, Mainland China, Hong Kong, and Macau are among the world's largest and most prosperous economies. East Asia borders Siberia and the Russian Far East to the north, Southeast Asia to the south, South Asia to the southwest, and Central Asia to the west. To the east is the Pacific Ocean and to the southeast is Micronesia (a Pacific Ocean island group, classifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Koenigia × Fennica
''Koenigia'' × ''fennica'', known as Finnish knotweed, is a hybrid between two species of ''Koenigia'', ''K. alpina'' and ''K. weyrichii'', members of the family Polygonaceae, the knotweed family. It generally only known as a cultivated garden plant, but plants have been recorded a few times surviving in abandoned areas in northern Europe, especially in Finland. The cultivar 'Johanniswolke' is considered an attractive ornamental perennial plant. Description Like the other species of the former genus ''Aconogonon'' (all now classified in ''Koenigia''), the hybrid is a perennial, growing from short rhizomes. It grows to about , with leaves up at least long and about wide. The hybrid is intermediate in appearance between its parents. It differs from ''Koenigia weyrichii'' in having less persistent ochreas (sheaths surrounding the stems), less pointed leaves with fewer hairs on the underside, pedicels that are jointed in the upper part, and larger tepals. It has broader leaves th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Koenigia Alpina
''Koenigia alpina'' (synonym ''Aconogonon alpinum''), commonly known as alpine knotweed, is similar to '' Koenigia alaskana'', but differs in leaf size and achene characteristics. It is native to Europe and temperate Asia. It is one of the parents of the cultivated hybrid ''Koenigia'' × ''fennica'', the other being ''Koenigia weyrichii ''Koenigia weyrichii'' (synonym ''Persicaria weyrichii''), the Chinese knotweed or Weyrich's knotweed, is a large, perennial, rhizomatous herb native to East Asia.

International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The stan ...
