Nephrolepis exaltata (Linnaeus) Schott ssp. exaltata . Phen: Jan-Dec. Hab: Epiphytic or terrestrial in a range of open to shaded moist habitats. Dist: Panhandle and ne. FL south to s. FL; West Indies; Central and South America; widely introduced elsewhere. Marginally present in GA (Jekyll island, Glynn County, Max Medley, pers.comm. 2022), where it seemed to have been in place for several years but then died; not likely to become established, but included because it is likely to be observed occasionally where it appears to be naturalized, or at least stably persistent.
Origin/Endemic status: Native
Taxonomy Comments: N. exaltata ssp. exaltata appears to be a trigenomic hybrid involving N. cordifolia, N. biserrata, and probably N. brownii, with normal, sexual fertility (Yahaya et al. 2016). Ssp. hawaiiensis W.H. Wagner is endemic to the Hawaii Islands.
