Abstract
The name Asplenium ⨉ montanum C. S. Lee & K. Lee (2015: 364) was published as a multiple hybridization species of three species, a name that applies to an endemic fern occurring in shadowy forest of the Korean Peninsula (Chung et al. 2017). In the latest revision, however, its name was should be treated as illegitimate name since it is a later homonym of Asplenium montanum Willdenow (1810: 342) (Art. 53.1 of ICN, Turland et al.2018).
