Discussion

Liatris hirsuta occupies a geographic range separate from and nearly contiguous with L. squarrosa. They have been treated as a single species. Liatris hirsuta is sympatric (without intergrades) with L. squarrosa var. squarrosa in Texas, Oklahoma, Louisiana, and Mississippi; it is sympatric with L. compacta in Arkansas; it intergrades with L. cylindracea in Missouri. See also discussion under 1. L. compacta.
