Liatris pilosa
Liatris provincialis
Of conservation concern.
Liatris provincialis is very similar to L. chapmanii and apparently restricted to coastal and near-coastal sites in panhandle of Florida (Franklin and Wakulla counties). Beside the difference in orientation of the heads, phyllaries of L. provincialis are broader (versus gradually and more narrowly lanceolate), often abruptly acute to short-acuminate or cuspidate, but there is little else to distinguish the two. Liatris provincialis is in the Center for Plant Conservation’s National Collection of Endangered Plants.
