Asters
''Aster'' is a genus of perennial flowering plants in the family Asteraceae. Its circumscription has been narrowed, and it now encompasses around 170 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. The name ''Aster'' comes from the Ancient Greek word (''astḗr''), meaning "star", referring to the shape of the flower head. Many species and a variety of hybrids and varieties are popular as garden plants because of their attractive and colourful flowers. 'Aster' species are used as food plants by the larvae of a number of Lepidoptera species—see list of Lepidoptera that feed on ''Aster''. Asters can grow in all hardiness zones. Circumscription The genus ''Aster'' once contained nearly 600 species in Eurasia and North America, but after morphologic and molecular research on the genus during the 1990s, it was d ...

Symphyotrichum
''Symphyotrichum'' () is a genus of over 100 species and naturally occurring hybrids of herbaceous annual and perennial plants in the composite family Asteraceae, most which were formerly treated within the genus ''Aster''. The majority are endemic to North America, but several also occur in the West Indies, Central and South America, as well as in eastern Eurasia. Several species have been introduced to Europe as garden specimens, most notably New England aster (''Symphyotrichum novae-angliae'') and New York aster (''Symphyotrichum novi-belgii''). Description Brouillet, et al. wrote: Taxonomy of ''Symphyotrichum'' is difficult. Species are usually heterophyllous, some strongly so. Individuals in the spring, with basal rosettes, often have leaf shapes quite different from those with cauline leaves seen later in the season. Phyllary shape on first- and later-formed heads may differ. Individuals may vary considerably in plant size and array development depending upon growing con ...

Ionactis
''Ionactis'', common name stiff-leaved asters or ankle-asters, is a small genus of plants belonging to the family Asteraceae. These aster-like plants are endemic to North America (Canada and the United States).Greene, Edward Lee. 1897. Pittonia 3(17C): 245–246 entirely in English One species is widespread across much of the eastern half of the continent, while two others are rare endemics with very restricted ranges (see below). The generic name, ''Ionactis'', is derived from the Greek words "ion," meaning "violet" and "aktis" meaning "ray." This is in allusion to the ray florets, frequently pale purple in this genus.

Michaelmas
Michaelmas ( ; also known as the Feast of Saints Michael, Gabriel, and Raphael, the Feast of the Archangels, or the Feast of Saint Michael and All Angels) is a Christian festival observed in some Western liturgical calendars on 29 September, and on 8 November in the Eastern tradition. Michaelmas has been one of the four quarter days of the English and Irish financial, judicial, and academic year. In Christian angelology, the Archangel Michael is the greatest of all the angels; he is particularly honored for defeating Lucifer in the war in heaven. History In the fifth century, a basilica near Rome was dedicated in honour of Saint Michael the Archangel on 30 September, beginning with celebrations on the eve of that day. 29 September is now kept in honour of Saint Michael and all Angels throughout some western churches. The name Michaelmas comes from a shortening of "Michael's Mass", in the same style as Christmas (Christ's Mass) and Candlemas (Candle Mass, the Mass where tr ...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Doellingeria
''Doellingeria'' is a genus of flowering plants in the family Asteraceae. It contains species formerly included in ''Aster'' but now considered to be a distinct genus. They are known commonly as tall flat-topped asters''Doellingeria''. Flora of North America. or whitetops.''Doellingeria''. Integrated Taxonomic Information System (ITIS). There is still some disagreement as to which species should be included in ''Doellingeria.'' Some authorities include up to 10 or 11 species in ''Doellingeria'', but |
Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Oligoneuron
''Solidago'' sect. ''Ptarmicoidei'' is a section of flowering plants in the genus ''Solidago''. They are sometimes considered a separate genus: ''Oligoneuron''. Like related species they are known as goldenrods. This section contains seven species of perennial herbs, all native to North America. They are distinguished from other goldenrods by their corymbiform flowerheads, which are flat or rounded in profile and about as broad as tall or broader, for which they are sometimes called flat-topped goldenrods. Species The following seven species are included in ''Solidago'' sect. ''Ptarmicoidei'': *'' Solidago houghtonii'' Torrey & A. Gray – Houghton's goldenrod *'' Solidago nitida'' Torrey & A. Gray – shiny goldenrod *''Solidago ohioensis'' Riddell – Ohio goldenrod *'' Solidago ptarmicoides'' (Torrey & A. Gray) B.
