Chrysopsis floridana Small is a rare and endangered species native to the Tampa Bay area of Florida and a small disjunct area near the base of the central ridge. It has ovate woolly leaves and phyllaries that are densely stipitate glandular. The fruits lack reddish brown ridges. The species is diploid (2n=10). Semple & Steenhof (2025) compared C. scabrella, C. delaneyi, C. highlandsensis, and C. floridana in a multivariate morphometric analysis with leaf hair length, number of disc florets, mid stem leaf length, and upper stem leaf width being the statistically strongest traits separating the four species.
