Polygonum boreale is a species of flowering plant belonging to the family Polygonaceae. [1]
The Polygonaceae are a family of flowering plants known informally as the knotweed family or smartweed—buckwheat family in the United States. The name is based on the genus Polygonum, and was first used by Antoine Laurent de Jussieu in 1789 in his book, Genera Plantarum. The name may refer to the many swollen nodes the stems of some species have, being derived from Greek, poly meaning 'many' and gony meaning 'knee' or 'joint'. Alternatively, it may have a different derivation, meaning 'many seeds'.
Polygonum is a genus of about 130 species of flowering plant in the buckwheat and knotweed family Polygonaceae. Common names include knotweed and knotgrass. In the Middle English glossary of herbs Alphita, it was known as ars-smerte. There have been various opinions about how broadly the genus should be defined. For example, buckwheat has sometimes been included in the genus as Polygonum fagopyrum. Former genera such as Polygonella have been subsumed into Polygonum; other genera have been split off.
Fallopia is a genus of about 12 species of flowering plants in the buckwheat family, often included in a wider treatment of the related genus Polygonum in the past, and previously including Reynoutria. The genus is native to temperate and subtropical regions of the Northern Hemisphere, but species have been introduced elsewhere. The genus includes species forming vines and shrubs.
There are 164 vascular plant species on the Norwegian Arctic archipelago of Svalbard. This figure does not include algae, mosses, and lichens, which are non-vascular plants. For an island so far north, 164 species constitutes an astonishing variety of plant life. Because of the harsh climate and the short growing season, all the plants are slow growing. They seldom grow higher than 10 cm.
Persicaria pensylvanica is a species of flowering plant in the buckwheat family, Polygonaceae. It is native to parts of North America, where it is widespread in Canada and the United States. It has also been noted as an introduced species in parts of Europe and South America. Common names include Pennsylvania smartweed and pinkweed.
Reynoutria multiflora is a species of flowering plant in the buckwheat family Polygonaceae. It is known as tuber fleeceflower and Chinese knotweed. It is native to central and southern China.
Polygonum aviculare or common knotgrass is a plant related to buckwheat and dock. It is also called prostrate knotweed, birdweed, pigweed and lowgrass. It is an annual found in fields and wasteland, with white flowers from June to October. It is widespread across many countries in temperate regions, apparently native to Eurasia and North America, naturalized in temperate parts of the Southern Hemisphere.
Galium boreale or northern bedstraw is a plant species of the Rubiaceae. It is widespread over the temperate and subarctic regions of Europe, Asia and North America including most of Canada and the northern United States.
Muehlenbeckia adpressa, commonly known as climbing lignum, is a prostrate or climbing plant, native to Australia. It has thin red-brown stems up to 1 metre in length. The leaves are 1.5–6 centimetres (0.59–2.36 in) long and 1.5–3.5 centimetres (0.59–1.38 in) wide. It occurs in coastal areas of Western Australia, South Australia, Tasmania, Victoria and New South Wales.
Persicaria chinensis, commonly known as creeping smartweed or Chinese knotweed, is a plant species from the family Polygonaceae. It is widespread across China, Japan, the Indian Subcontinent, Indonesia, Malaysia, and Vietnam. It is a common plant in Malaysia and Vietnam, where it is used in herbal remedies, such as for the treatment of dysentery, enteritis, and sore throat. It is a weed in some coastal areas of New South Wales and Queensland in Australia.
Polygonum delopyrum, the fringed jointweed or hairy jointweed, is a plant species endemic to Florida. It is found in pinelands and sandy pine barrens at elevations less than 50 m, in central and southern parts of the state.
Polygonum serotinum, commonly called southern jointweed or American jointweed, is a species of flowering plant in the knotweed family. It is native to Southeastern United States extending in scattered locations west to New Mexico. Its preferred habitat is dry, sandy areas.
Polygonum agreste is a species of flowering plant in the family Polygonaceae, native to Uzbekistan. It was first described by Georgji Sumnevicz in 1940.
Polygonum polyneuron is a species of flowering plant in the family Polygonaceae, native to Japan, Korea, the Kuril Islands, and Primorye. It was first described by Adrien René Franchet & Ludovic Savatier.
Polygonum exsertum is a species of flowering plant in the family Polygonaceae, native to Illinois. It was first described by John Kunkel Small in 1894.
Polygonum deciduum is a species of flowering plant in the family Polygonaceae, native to Uzbekistan. It was first described in 1856.
Polygonum oxyspermum is a coastal species of flowering plant in the buckwheat family. It is native to Europe, primarily along the shores of the Atlantic, the North Sea, and the Baltic Sea, from France and Ireland to Finland and Russia. It is also naturalized in eastern Canada and in the US State of Maine.
Andersonglossum boreale, known as northern wild comfrey or just wild comfrey, is a species of flowering plant in the borage family, Boraginaceae. It is native to boreal coniferous and mixed forests in North America, from Nova Scotia to British Columbia and Yukon in Canada, south to New Jersey and Indiana in the United States. It is often found in rocky or sandy soils. It is extirpated from many of the southern parts of its range.
Polygonum ciliinode is a species of flowering plant in the family Polygonaceae, native to central and eastern Canada, and the north-central and eastern United States. The specific epithet is also spelt cilinode.
Polygonum rurivagum is a species of flowering plant belonging to the family Polygonaceae.
