Dryopteris goldiana is diploid and is one of the parents of D. celsa and of D. clintoniana. Dryopteris goldiana hybridizes with five species. Hybrids can be identified by the glossy dark scales and large blade size. A remarkable additional hybrid (× Dryostichum singulare W. H. Wagner), involving this species and Polystichum lonchitis, is known from Gray and Simcoe counties, Ontario. It is intermediate between the parents and is sterile (W. H. Wagner Jr., F. S. Wagner et al. 1992).
