Current studies in the genus Wyethia (Compositae) reveal that the entity hitherto called Wyethia mexicana Watson differs from the other species of this genus in a number of important characters which are believed to be of generic value. Indeed, Watson expressed his own doubts as to its affinities when, in the original description, he noted that the plant was "rather abnormal in habit and involucre.,, The presence of fertile ray flowers and alternate leaves may have been prime considerations in… Expand

An ITS phylogeny of Balsamorhiza and Wyethia (Asteraceae: Heliantheae).
TLDR
The relationships among the species of Balsamorhiza and Wyethia (Asteraceae: Heliantheae) were examined using data from the internal transcribed spacer (ITS) region of the nuclear ribosomal DNA to show that the two groups together form a monophyletic group. Expand
Phylogenetic analysis of Silphium and subtribe Engelmanniinae (Asteraceae: Heliantheae) based on ITS and ETS sequence data.
TLDR
It is suggested that the cypsela complex, which is present in Berlandiera, Chrysogonum, Engelmannia, and Lindheimera, arose only once and was subsequently lost in Silphium, and supported the expansion of subtribe Engelmanniinae to include Balsamorhiza, Borrichia, Rojasianthe, Vigethia and Wyethia.
