Dist: Endemic to peninsular Fl and se. GA; reports of it in n. AL were probably based on aberrant individuals of P. graminifolia.

Taxonomy Comments: See Bridges & Orzell (2018b) for detailed discussion. This taxon can be diploid (2n=18), tetraploid (2n=36), or hexaploid (2n=54). A large complex of forms are produced by this variation in ploidy level, and possible introgression, for a detailed discussion with illustrations see Nesom (2019a).
