The type of Phymatopsis cartilagineoserrata is a good match with that of Selliguea malacodon, which has rhizome scales with a light ciliate margin and curved pinnae with sharply aristate teeth. Chinese material previously named as Phymatopteris malacodon is here included within the following species, S. albidoglauca.
