Symphyotrichum chilense (formerly "Aster chilensis") is a species of aster known by the common names Pacific aster and common California aster.
Symphyotrichum ericoides, syn.
 "Aster ericoides" (common name white heath aster, white aster or heath aster), is a species of flowering plant in the family Asteraceae, native to much of North America, as well as northern Mexico.
 It has also been introduced to many areas beyond its native range.
Laelia is a small genus of 25 species in the orchid family (Orchidaceae).
 "Laelia" species are found in areas of subtropical or temperate climate in Central and South America, but mostly in Mexico.
 "Laelia" is abbreviated L. in the horticultural trade.
Aster yellows is a chronic, systemic plant disease caused by a bacterium-like organism called a phytoplasma.
 The aster yellows phytoplasma (AYP) affects 300 species in 38 families of broad-leaf herbaceous plants, primarily in the aster family, as well as important cereal crops such as wheat and barley.
 Symptoms are variable and can include phyllody, virescence, chlorosis, stunting, and sterility of flowers.
 The aster leafhopper vector, "Macrosteles quadrilineatus", moves the aster yellows phytoplasma from plant to plant.
 Its economic burden is primarily felt in the carrot ("Daucus carota" ssp."
 sativus") crop industry, as well as the nursery industry.
 No cure is known for plants infected with aster yellows.
 Infected plants should be removed immediately to limit the continued spread of the phytoplasma to other susceptible plants.
 However, in agricultural settings such as carrot fields, some application of chemical insecticides has proven to minimize the rate of infection by killing the vector.
Eurybia macrophylla, commonly known as the bigleaf aster, large-leaved aster, largeleaf aster or bigleaf wood aster, is an herbaceous perennial in the composite family that was formerly treated in the genus "Aster".
 It is native to eastern North America, with a range extending from eastern and central Canada (from Nova Scotia to Manitoba) through the northeastern deciduous and mixed forests of New England and the Great Lakes region and south along the Appalachians as far as the northeastern corner of Georgia, and west as far as Minnesota, Missouri and Arkansas.
 The flowers appear in the late summer to early fall and show ray florets that are usually either a deep lavender or violet, but sometimes white, and disc florets that are cream-coloured or light yellow, becoming purple as they mature.
 It is one of the parent species of the hybrid "Eurybia × herveyi".
Aster is a genus of 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.
Laelia marginata is a species of orchid in genus "Laelia".
 "L. marginata" is found in Suriname.
Symphyotrichum lanceolatum (syn.
 "Aster lanceolatus") is a species of flowering plant in the aster family, Asteraceae.
 It is native to Canada and the United States.
 Common names include panicled aster, tall white aster, eastern line aster, lance-leaf aster, narrow-leaf Michaelmas daisy, and white-panicle aster.
Symphyotrichum ascendens (formerly "Aster ascendens") is a species of aster known by the common names western aster and long-leaved aster.
 It is native to western North America from British Columbia to Saskatchewan, the Sierra Nevada in California, to Arizona and New Mexico.
 It grows in many types of habitat, including disturbed areas.
Symphyotrichum ( ) is a genus of about 90 species of herbaceous annual and perennial plants in the composite family (Asteraceae) that were formerly treated within the genus "Aster".
 The majority are endemic to North America, but several species also occur in the West Indies, Central and South America, as well as in eastern Eurasia.
 Many species have been introduced to Europe as garden specimens, most notably the New England aster ("Symphyotrichum novae-angliae") and the New York aster ("Symphyotrichum novi-belgii").
