• Type: "Ceylon, s. dat. Mrs Walker s.n. (lecto: K 001089022*; isolecto: B 200145161!"

• Text: "Kramer and Tindale (1976, p. 99) cited the type of the name Lindsaea walkerae as ‘holotype: Ceylon, (Mrs) Walker (K). Isotype: (B)’. This is here treated as effective lectotypification by Kramer and Tindale, in accordance with ICN Art. 7.11 (Turland et al. 2018). Because their citation meets the relevant requirements of ICN Art. 7.11, the use of the term ‘holotype’ is correctable under ICN Art. 9.10."
