Discusión taxonómica
(In relation to the synonym) Polypodium cryptocarpon has abaxial scales that vary from lanceolate to acicular and are more shallowly fimbriate than those of P. furfuraceum, being cut ca. 1⁄4 the way to the middle. In addition, the pinnae are nearly glabrous adaxially.
Polypodium cryptocarpon has undulate (vs. straight) pinna margins and narrow, often slightly falcate or slightly ascending pinnae. Abaxial scales are scattered with short teeth (vs. Scales dense, larger, with hair-like teeth in P. furfuraceum), the adaxial blade scales sparse to absent (vs. scattered).A
