Liatris elegans
Liatris cokeri
Varieties 4 (4 in the flora).
Variety elegans extends across the geographic range of the species; the other three varieties form local enclaves essentially imbedded within var. elegans and sporadically intergrading with it at points of contact (see further comments under 10d. var. kralii).
(Discussion copyrighted by Flora of North America; reprinted with permission.)
Pyne and Stucky noted that variants of Liatris cokeri (apparently intermediate toward L. virgata) occur on the coastal plain of North Carolina and South Carolina.
