Erigeron
''Erigeron'' () is a large genus of plants in the family Asteraceae. It is closely related to the genus ''Aster'' and the true daisies in the genus ''Bellis''. The genus has a cosmopolitan distribution in dry, mountainous areas and grassland, with the highest diversity in North America. Etymology Its English name, fleabane, is shared with related plants in several other genera. It appears to be derived from a belief that the dried plants repelled fleas or that the plants were poisonous to fleas. The generic name ''Erigeron'' is derived from the Ancient Greek words (''êri'') "early in the morning" and (''gérōn'') "old man", a reference to the appearance of the white hairs of the fruit soon after flowering or possibly alluding to the early appearance of the seed heads. The noun is masculine, so that specific epithets should have masculine endings (e.g. ''glaucus'') to agree with it. However, authors have incorrectly used neuter endings (e.g. ''glaucum''), because the ending ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inula
''Inula'' is a genus of about 80 species of flowering plants in the family Asteraceae, native to Europe, Asia and Africa. They may be annuals, herbaceous perennials or subshrubs that vary greatly in size, from small species a few centimeters tall to enormous perennials over tall. They carry yellow daisy-like composite flowerheads often with narrow ray-florets. Some common characteristics include pappus with bristles, flat capitulum, and lack of chaff. Several species are popular flowers for the garden, with cultivation going back to antiquity. The smaller species are used in rock gardens and the more common larger ones, which tend to have very coarse foliage, in borders. Etymology The genus name ''Inula'' is of uncertain origin, and was already in use by the Romans. The Latin phrase ''inula campana'' (field inula) gave rise to the English whose scientific name is ''Inula helenium''. The plant's specific name, ''helenium'', derives from Helen of Troy; elecampane is sai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pluchea
''Pluchea'' is a genus of flowering plants in the tribe Inuleae within the family Asteraceae. Members of this genus might be known as camphorweeds, plucheas, or less uniquely fleabanes. Some, such as ''P. carolinensis'' and ''P. odorata'', are called sourbushes. There are plants of many forms, from annual and perennial herbs to shrubs and trees, and there is variation in the morphology of leaves, flowers, and fruits.Perera, W., et al. (2007)Flavonols from leaves of ''Pluchea carolinensis'' (Jacq.) G.Don (Asteraceae).'' Revista Latinoamericana de Química'' 35(3), 68-73.

Conyza
''Conyza'' (horseweed, butterweed or fleabane) is a genus of flowering plants in the family Asteraceae. They are native to tropical and warm temperate regions throughout the world, and also north into cool temperate regions in North America and eastern Asia. The New World species of the genus are closely related to ''Erigeron'' (also known as fleabanes). The species are annual or perennial herbaceous plants, rarely shrubs, growing to 1–2 m tall. The stems are erect, branched, with alternate leaves. The flowers are produced in inflorescences, with several inflorescences loosely clustered on each stem. Many species of the genus ''Conyza'' are ruderal species and some have been found to be resistant to the herbicide glyphosate Glyphosate (IUPAC name: ''N''-(phosphonomethyl)glycine) is a broad-spectrum Herbicide, systemic herbicide and Crop desiccation, crop desiccant.

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Astereae
Astereae is a tribe of plants in the family Asteraceae that includes annuals, biennials, perennials, subshrubs, shrubs, and trees. They are found primarily in temperate regions of the world. Plants within the tribe are present nearly worldwide divided into over 250 genera and more than 3,100 species, making it the second-largest tribe in the family behind Senecioneae. The taxonomy of the tribe Astereae has been dramatically changed after both morphologic and molecular evidence suggested that large genera such as '' Aster'', as well as many others, needed to be separated into several genera or shifted to better reflect the plants' relationships. A paper by R. D. Noyes and L. H. Rieseberg showed that most of the genera within the tribe in North America actually belong to a single clade, meaning they have a common ancestor. This is referred to as the North American clade. Guy L. Nesom and Harold E. Robinson have been involved in the recent work and are continuing to re-categoris ...

Pulicaria
''Pulicaria'' is a genus of flowering plant in the sunflower family, native to Europe, Asia, and Africa. In North America ''Pulicaria'' is known by the common name false fleabane. ''Pulicaria'' species accepted by the Plants of the World Online as of June 2022: *'' Pulicaria adenophora'' *'' Pulicaria albida'' *'' Pulicaria alveolosa'' *'' Pulicaria angustifolia'' *'' Pulicaria arabica'' *'' Pulicaria argyrophylla'' *'' Pulicaria armena'' *''Pulicaria aromatica'' *'' Pulicaria attentuata'' *'' Pulicaria aualites'' *'' Pulicaria aucheri'' *'' Pulicaria auranitica'' *''Pulicaria aylmeri'' *''Pulicaria baluchistanica'' *''Pulicaria boissieri'' *''Pulicaria burchardii'' *''Pulicaria canariensis'' *''Pulicaria carnosa'' *''Pulicaria chrysantha'' *''Pulicaria clausonis'' *''Pulicaria collenettei'' *''Pulicaria confusa'' *'' Pulicaria diffusa'' *'' Pulicaria dioscorides'' *'' Pulicaria discoidea'' *'' Pulicaria diversifolia'' *'' Pulicaria dumulosa'' *''Puli ...

Vernonia
''Vernonia'' is a genus of about 350 species of forbs and shrubs in the Daisy family Asteraceae. Some species are known as ironweed. Some species are edible and of economic value. They are known for having intense purple flowers. There have been numerous distinct subgenera and subsections named in this genus, and some botanists have divided the genus into several distinct genera. For instance, the ''Flora of North America'' recognizes only about twenty species in ''Vernonia'' ''sensu stricto'', seventeen of which are in North America north of Mexico, with the others being found in South America. Taxonomy The genus was circumscribed by Johann Christian Daniel von Schreber in Gen. Pl. ed. 8 vol.2 on page 541 in 1791. The genus name of ''Vernonia'' is in honour of William Vernon (1666/67 - ca.1711), who was an English plant collector, ( bryologist) and entomologist from Cambridge University, who collected in Maryland, USA in 1698.

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') 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". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

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 subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While ... Sources {{biology-stub ...

Asteroideae
Asteroideae is a subfamily of the plant family Asteraceae. It contains about 70% of the species of the family. It consists of several tribes, including Astereae, Calenduleae, Eupatorieae, Gnaphalieae, Heliantheae, Senecioneae and Tageteae. Asteroideae contains plants found all over the world, many of which are shrubby. There are about 1,135 genera and 17,200 species within this subfamily; the largest genera by number of species are ''Helichrysum'' (500–600) and ''Artemisia'' (550). Asteroideae is said to date back to approximately 46–36.5 million years ago. Common characteristics This family will often have radiate style heads but some could have discoid or disciform. They contain ray florets that are three lobed and are also considered perfect flower implying that it is bisexual. Many contain stigmatic surfaces that are separated by two marginal bands and terminal sterile appendages with sweeping hairs. Taxonomy This subfamily is composed of 21 tribes that are broken i ...
