450.7241 Genus Erigeron L.; Sp. Pl. 2: 863 (1753)

Distribution: cosmopolitan, mostly mountains and dry areas of northern hemisphere, esp. North America (173) and Mexico, also many in arctic and high alpine environments, but (almost) completely missing in Africa. New World species of Conyza are completely included here, but many combinations are still missing. African representatives belong to other groups like Nidorella or Eschenbachia.

Remarks: acris agg. Several species of the complex in Central Europe are now treated as full species. Many synonyms still listed here might belong to one of the split species, like E. muralis. More of the subspecies possibly deserve recognition as full species. The North American populations are listed here under E. kamtschaticus.

Remarks: Subgen. Phalacroloma. A highly polymorphic, triploid species with a lot of quasi-apomictic clones, which better not deserve taxonomic recognition, because they are not stable against hybridization in the field. The long recognized entities ´septentrionalis´ or ´lilacinus´ are such clones. ´Septentrionalis´ does not belong to E. strigosus but here.
