Persicaria Capitata
''Persicaria capitata'', the pink-headed persicaria, pinkhead smartweed, pink knotweed, Japanese knotweed, or pink bubble persicaria, is an Asian species of plants in the genus ''Persicaria'' within the Polygonaceae (US: buckwheat) family. It is native to Asia (China, South Asia, Indochina) and grown as an ornamental in other countries. It has become naturalized in Australia, South Africa and a few scattered locations in the Americas. Description ''Persicaria capitata'' is a prostrate shrub, prostrate herb. The leaves are 1–6 cm long, 0.7–3 cm wide with pink to red bands or blotches and short scattered hairs. The Spike (botany), spikes are 5–10 mm long and 5–7 mm in diameter. Distribution and habitat ''Persicaria capitata'' is a native of Asia. It has naturalised in parts of Australia and North America. Between 2008 and 2013 it has been recorded as an invasive plant in Ireland from the Counties Fermanagh, Kilkenny, Wexford and Mayo. Uses ''Pe ...

Tepal
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, ''Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undiffer ...

Bistorta
''Bistorta'' is a genus of flowering plants in the family Polygonaceae. about 40 species are accepted. It has been supported as a separate clade by Molecular phylogenetics, molecular phylogenetic analysis. ''Bistorta'' species are native throughout much of the Northern Hemisphere, as far south as Mexico in North America and Thailand in Asia. Description Species of ''Bistorta'' are Perennial plant, perennial herbaceous plants. Their roots are fibrous, forming rhizomes. They have erect, unbranched Plant stem, stems. Their leaves are usually longer than wide, mostly basal, but with some arranged alternately on the stems. The inflorescences are spikelike. The individual flowers have five white to purple-pink (rarely red) tepals. The flowers are bisexual, although the 5–8 stamens are sometimes poorly developed. There are three Style (botany), styles. The fruits are in the form of achenes, that are brown or dark brown, unwinged, and three-angled. The Ploidy, monoploid number of chrom ...

Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxono ...

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxa ranked above species are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polygonoideae
Polygonoideae is a subfamily of plants in the family Polygonaceae. It includes a number of plants that can be highly invasive, such as Japanese knotweed, '' Reynoutria japonica'', and its hybrid with '' R. sachalinensis'', ''R.'' × ''bohemica''. Boundaries between the genera placed in the subfamily and their relationships have long been problematic, but a series of molecular phylogenetic studies have clarified some of them, resulting in the division of the subfamily into seven tribes. Taxonomy Phylogeny A 2015 molecular phylogenetic study suggested that the genera and tribes in Polygonoideae were related as shown in the following cladogram. ''Rumex'' included ''Emex'', and '' Fallopia'' was not monophyletic, with some species placed outside the main group in the tribe Polygoneae, and some others grouping with '' Pteroxygonum'', placed in the tribe Pteroxygoneae. Genera Some of the boundaries between the genera are not settled ; in particular, '' Fallopia'' is at least paraph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end botanical subfamily names with "-oideae", and zoological subfamily names with "-inae". Detarioideae is an example of a botanical subfamily. Detarioideae is a subdivision of the family Fabaceae (legumes), containing 84 genera. Stevardiinae is an example of a zoological subfamily. Stevardiinae is a large subdivision of the family Characidae, a diverse clade In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants.

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...
