Liatris elegans
Liatris chapmanii
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).
