Map of select IRC data for peninsular Florida

SOUTH FLORIDA Occurrence: Present

SOUTH FLORIDA Native Status: Native

SOUTH FLORIDA Cultivated Status: Cultivated

Comments: Weakley et al. (2017) elevate this to species rank: Liatris quadriflora (Chapm.) E.L. Bridges & Orzell. This is on our list to change in the FISF. The vast majority of plants in this group in South Florida appear to be this taxon. The Florida Atlas also reports Liatris tenuifolia for Miami-Dade County based on several specimens at USF, but these need to be examined. Liatris laevigata, which has previously been placed into synonymy under this taxon or confused with it on many species lists, is accepted also as a valid species by Weakley et al. (2017); it may be native to South Florida (e.g. Cooley et al. 9032 USF), but this also needs some investigation (E.L. Bridges, email comm. 2017).

Synonyms: Laciniaria laevigata, misapplied; Liatris laevigata, misapplied; Liatris tenuifolia, misapplied; Liatris tenuifolia var. laevigata, misapplied.
