According to Bremer and Humphries [ 2 ] , the Artemisia -group is monophyletic and defined by heterogamous-disciform capitula (disk florets usually bisexual and fertile, ray florets pistillate) or homogamous-discoid capitula (disk florets usually bisexual and fertile, ray florets absent), pollen with short or no spines (associated with anemophily), and thick-walled cypselas devoid of ribs (sometimes faint ribs are present in Sphaeromeria and Crossostephium ). All of the Artemisia -group genera contain species that have been variously placed within the taxonomic boundaries of Artemisia s.l.
primarily based on the presence or absence of ray florets and the fertility/sterility of disk florets: (1) Abrotanum Besser ( Artemisia of later authors) - ray florets pistillate and fertile; disk florets perfect and fertile; receptacle glabrous; (2) Absinthium (Mill.)
Sphaeromeria also has heterogamous-disciform capitula with pistillate ray and perfect disk florets, as does heterogamous-disciform S. bigelowii , suggesting that it is indeed a plesiomorphy.
It is apparently defined taxonomically on the basis of plesiomorphies (heterogamous, disciform capitula with perfect/fertile disk florets and pistillate ray florets), and needs to be re-circumscribed.
