Discusión taxonómica
Polypodium colpodes is distinguished from P. hispidulum by the narrower, somewhat bicolorous, spreading, denticulate rhizome scales and the lustrous, castaneous stipes and rachises (vs. appressed, concolorous scales). It is closest to P. arcanum, from which it differs in the darker stipes and/or rachises and alternate pinnae. This complex is in need of more study.
