Pteris sinensis was proposed as a replacement name for P. inaequalis Baker in the belief that this was a later homonym of P. inaequalis C. Presl (Tent. Pterid. 145. 1836). However, Presl’s name is a nomen nudum and was not therefore validly published (Melbourne Code, Art. 38.1(a)). Baker’s name is therefore legitimate and the correct name for this taxon.
