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.

In addition, we explained [ 34 35 ] an unexpected relationship between it and A. filfifolia as possible hybridization and introgression involving bidirectional gene flow rather than recent common ancestry because heterogamous-disciform A. bigelowii differs from heterogamous-disciform A. filifolia by perfect disk florets instead of female-sterile disk florets.
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.
Tridentatae is characterized by discoid-homogamous capitula, with the exception of S. bigelowii , which has occasional heterogamous-disciform capitula of one pistillate ray floret and two perfect disk florets - a character that was previously considered a plesiomorphy or secondary reversal in S. bigelowii [ 2 ] .
