Elaphoglossum albomarginatum closely resembles a large specimen of E. pallidum, but differs not only in size but also in the rhizome scales and the pale margins on both the sterile and fertile blades. Marginal blade scales are absent in E. albomarginatum, whereas in E. pallidum at least an occasional marginal scale is found.A
