According to the reference link, "this complex was recently revised to recognize five species occurring in Florida: P. aequilifolia (endemic), P. latifolia (endemic), P. graminifolia s.str., P. microcephala, and P. tracyi (endemic) (Weakley et al. 2018)." I'm not sure which it is, so I am leaving it at this species for now.
