Lemmaphyllum diversum has been variously misidentified as L. subrostratum (C. Christensen) Ching (Tagawa, Acta Phytotax. Geobot. 5: 112. 1936), Lepidogrammitis rostrata (Beddome) Ching (De Vol & Kou, Fl. Taiwan 1: 183, t. 63. 1975), and Polypodium megasorum C. Christensen (Hayata, Icon. Pl. Formosan. 8: 153. 1919). "Polypodium chingii C. Christensen" is a herbarium name that was included in the synonymy of Lemmaphyllum christensenii.
