Aster is a genus of perennial flowering plants in the family Asteraceae. Its circumscription has been narrowed, and it now encompasses around 180 species, all but one of which are restricted to Eurasia; many species formerly in Aster are now in other genera of the tribe Astereae. Aster amellus is the type species of the genus and the family Asteraceae.
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks above genus are capitalized, including both tribe and subtribe.
Carlina is a genus of flowering plants in the aster family, Asteraceae. It is distributed from Madeira and the Canary Islands across Europe and northern Africa to Siberia and northwestern China.
Cota tinctoria, the golden marguerite, yellow chamomile, or oxeye chamomile, is a species of perennial flowering plant in the sunflower family. Other common names include dyer's chamomile, Boston daisy, and Paris daisy. In horticulture this plant is still widely referred to by its synonym Anthemis tinctoria.
Leucanthemum is a genus of flowering plants in the aster family, Asteraceae. It is mainly distributed in southern and central Europe. Some species are known on other continents as introduced species, and some are cultivated as ornamental plants. The name Leucanthemum derives from the Greek words λευκός – leukos ("white") and ἄνθεμον – anthemon ("flower"). Common names for Leucanthemum species usually include the name daisy, but "daisy" can also refer to numerous other genera in the Asteraceae family.
Carduus is a genus of flowering plants in the aster family, Asteraceae, and the tribe Cynareae, one of two genera considered to be true thistles, the other being Cirsium. Plants of the genus are known commonly as plumeless thistles. They are native to Eurasia and Africa, and several are known elsewhere as introduced species. This genus is noted for its disproportionately high number of noxious weeds compared to other flowering plant genera.
In botany, a section is a taxonomic rank below the genus, but above the species. The subgenus, if present, is higher than the section, and the rank of series, if present, is below the section. Sections may in turn be divided into subsections.
Werner Rodolfo Greuter, in Genoa, Italy, as a Swiss national, is a botanist. He is the chair of the Editorial Committee for the International Code of Botanical Nomenclature (ICBN) - the Tokyo Code (1994) and the St Louis Code (2000). His proposed policy as regards registration of botanical names proved unpopular and in 1999 he stepped back, not being elected anew: he completed his term as chair to be succeeded at Vienna in 2005. He has returned as a member of the editorial committee, contributing to the renamed International Code of Nomenclature for algae, fungi, and plants, the "Melbourne Code" (2012).
Tripolium pannonicum, called sea aster or seashore aster and often known by the synonyms Aster tripolium or Aster pannonicus, is a flowering plant, native to Eurasia and northern Africa, that is confined in its distribution to salt marshes, estuaries and occasionally to inland salt works.
Astereae is a tribe of plants in the family Asteraceae that includes annuals, biennials, perennials, subshrubs, shrubs, and trees. Plants within the tribe are present nearly worldwide divided into 170 genera and more than 2,800 species, making it the second-largest tribe in the family behind Senecioneae. They are found primarily in temperate regions of the world.
Eurybia sibirica, commonly known as the Siberian aster or arctic aster, is an herbaceous perennial native to north western North America and northern Eurasia. It is found largely in open areas of subarctic boreal forests, though it is also found in a wide variety of habitats in the region. It is similar in appearance to Eurybia merita, but their ranges overlap only near the border between the US and Canada, where E. sibirica is generally found at higher elevations.
Symphyotrichum lateriflorum is a species of flowering plant of the aster family (Asteraceae) native to eastern and central North America. Commonly known as calico aster, starved aster, and white woodland aster, it is a perennial, herbaceous plant that may reach 120 centimeters high and 30 centimeters across. Each flower head has many tiny florets put together into what appear as one.
Doellingeria is a genus of flowering plants in the aster family. It contains species formerly included in Aster but now considered to be a distinct genus. They are known commonly as tall flat-topped asters or whitetops.
Galatella is a genus of flowering plants in the daisy family, native to Europe, Asia, and northern Africa.
Tripolium is a genus of Eurasian and North African plants in the aster tribe within the sunflower family.
Cardopatium is a genus of flowering plants in the aster family, Asteraceae. They are native to the central and eastern Mediterranean region.
Carduncellus is a genus of flowering plants in the aster family, Asteraceae. They are native to the western Mediterranean and surrounding regions.
Galatella linosyris is a species of perennial plant from family Asteraceae found in Eastern, Central and Southern Europe. It can also be found in Great Britain, the southern part of Scandinavia and in Asia Minor. The flowers are yellow coloured. The species have stems up to 10–50 centimetres (3.9–19.7 in), with leaves that are lanceolate. The plant does not have ray flowers, only disk florets. It blooms from July to September. The fruits are achenes. The species is under protection in the Czech Republic.
Acacia sedifolia is a shrub of the genus Acacia and the subgenus Phyllodineae that is endemic to south western Australia.
