• Type: "Hunter River, Oct. 1804, R.Brown Iter Austral. 22 (lecto: BM 001048533*; possible isolecto: E 00108887*,"

• Text: "Jones and Bostock (1998, p. 413) cited the type of the name Nephrodium decompositum as ‘Hunter R., N.S.W., Oct. 1804, R. Brown Iter Austral. 22; holo: BM’. This is here treated as effective lectotypification by Jones and Bostock, in accordance with ICN Art. 7.11 (Turland et al. 2018). Because Jones and Bostock’s citation meets the relevant requirements of ICN Art. 7.11, their use of the term ‘holotype’ is correctable under ICN Art. 9.10."
