Classification
Systematics
The subtribe Microseridinae, following the circumscription by Kilian & al. (2009), comprises c. 115 species in c. 22 genera, of which all but one are principally North American. Picrosia is South American and one species (Microseris) is present in Australia and New Zealand as the results of long distant dispersal. Excluded is the unispecific genus Phalacroseris, which has been shown by Gemeinholzer & al. (in Kilian & al. 2009) to belong to the principally Old World subtribe Cichoriinae.\r\rPreviously the American clade has been treated as two (Stebbins 1953; Jeffrey 1966), three (Bremer 1994; Lack 2006) or nine (Lee & Baldwin 2004) subtribes or informal entities, respectively. Considering their radiation from a single common ancestor, it is, however, much more consistent with the phylogeny and the suprageneric classification of the entire tribe to reserve the subtribal rank to the American clade as such and to apply Lee & Baldwin’s classification to a subordinate informal rank of, e.g., "alliances". These are:
- Pinaropappus alliance: including Marshalljohnstonia and Pinaropappus
- Krigia alliance: including Krigia
- Pyrrhopappus alliance: including Picrosia and Pyrrhopappus
- Lygodesmia alliance: including Chaetadelpha, Lygodesmia and Shinnersoseris
- Glyptopleura alliance: including Glyptopleura
- Microseris alliance: including Agoseris, Microseris, Nothocalais, Stebbinsoseris and Uropappus
- Stephanomeria alliance: including Munzothamnus, Pleiacanthus, Prenanthella, Rafinesquia and Stephanomeria
- Malacothrix alliance: including Anisocoma, Atrichoseris, Calycoseris and Malacothrix.
