| Identification | Species 1 is tetraploid, whereas caroliniana is diploid. Cook (2015) says: "It can be distinguished from P. caroliniana by its broader peduncle and strobilus and by its longer peduncle leaves and sporophylls. These are 3.0 mm or shorter in P. caroliniana and typically 3.0 mm or longer in P. floridana." | |
| Taxonomic Comments | In a 2015 Master's Thesis at Miami Univ., Ohio, Cook distinguished diploid caroliniana from tetraploid "species 1," and gave it the specific epithet of floridana ined.. Thus, this name is not formally published. Taxon Editors will follow Weakley (2020) in accepting the new species.
