Notes
Until the work of Ching (1938) this species and others were much confused with Polypodium urophyllum Wall. (= Pronephrium repandum (Fee) Holttum), the present species also with Nephrodium latifolium Presl (= Pronephrium meniseiiearpon) and Aspidium glandulosum Bl. (Pronephrium glandulosum); under the last-named Mettenius also cited specimens of Sphaerostephanos peltochlamys (C. Chr.) Holttum (Zollinger 2608, 2920). Specimens from New Guinea and Queensland often have 1-2 short setae on sporangia.
