• Type: "Luzon, s. dat., T.P.X.Haenke s.n. (lecto: PR!; possible isolecto: PRC 450221!, PRC 450222!,"

• Etymology: "Bostock (1998d, p. 335) cited the type of the name Polypodium asperum as ‘T: Luzon, [Philippines], T.P.X.Haenke; holo: PR’. This is here treated as effective lectotypification by Bostock, in accordance with ICN Art. 7.11 (Turland et al. 2018). Because Bostock’s citation meets the relevant requirements of ICN Art. 7.11, his use of the term ‘holo’ is correctable under ICN Art. 9.10."
