    Osmunda peltata Sw., Prodr. 127. 1788. Acrostichum peltatum (Sw.) Sw., J. Bot. (Schrader) 1800(2): 11. 1801. Rhipidopteris peltata (Sw.) Schott ex Fe´e, Me´m. Foug. 2: 14. 1845. Peltapteris peltata (Sw.) C. V. Morton, Amer. Fern J. 45: 13. 1955. Type. Jamaica. Swartz s.n. (S!).

    Several varieties or forms have been recognized, based on dissection, from undivided to very finely divided; ours are all f. peltatum. This species, the most widespread representative of the splinter genus Peltapteris, is closely allied to E. squamipes, differing only in blade shape and dissection. Molecular studies (Skog et al., 2004) show Peltapteris nested within Elaphoglossum.
