Pteris nipponica was previously treated as a cultivar of Pteris cretica, and is known in cultivation under the name Pteris cretica cv. Albo-lineata. Pteris nipponica differs from P. cretica in that all pinnae are stalked, including the terminal pinna. By contrast, in Pteris cretica and Pteris ensiformis the uppermost pinnules are decurrent along the rachis, and the terminal pinna is usually fused with at least one of the adjacent lateral pinnules. Pteris cretica is a complex of diploid (2n=58) and triploid chromosome (3n=87) races. Pteris nipponica is a triploid, with 3n=87.
