The crenulate lead-plant occurs in the pine rockland habitats of southern Florida. Limestone erosion results in frequent solution holes and jagged surface features.
Many plants root in limestone crevices.
Large numbers of endemic rockland plants occur in the understory. All recently known specimens of the crenulate lead-plant have come from pinelands. The reproductive phenology of the crenulate lead-plant has not been recorded. Pollen and seed dissemination agents have not been reported. Nothing else has been reported.
