 After this split there are roughly 180 species within the genus, all but one being confined to Eurasia.The New World species have now been reclassified in the genera "Almutaster", "Canadanthus", "Doellingeria", "Eucephalus", "Eurybia", "Ionactis", "Oligoneuron", "Oreostemma", "Sericocarpus" and "Symphyotrichum", though all are treated within the same tribe, Astereae.Regardless of the taxonomic change, most are still widely referred to as "asters", or "Michaelmas daisies", because of their typical blooming period.
