• Type: "Deep Creek, Lord Howe Island, [15 Nov. 1913], W.R.B.Oliver [466] (lecto: WELT P00913/A-B*; isolecto: P 00522602!, P 00522603!"

• Text: "Green (1988, p. 655) cited the type of the name Marattia fraxinea var. howeana as ‘Type: Lord Howe Is., W. R. B. Oliver s.n. (holotype WELT; photo. K)’. This is here treated as effective lectotypification by Green, in accordance with ICN Art. 7.11 (Turland et al. 2018). Because Green’s citation meets the relevant requirements of ICN Art. 7.11, his use of the term ‘holotype’ is correctable under ICN Art. 9.10."
