• Type: "Norfolk Island, 1804–1805, F.L.Bauer s.n. (lecto:W n.v.; isolecto: BM 001048136*"

• Text: "Green (1994, p. 582) cited the type of the name Cyathea brownii as ‘Norfolk Island, 1804–1805, F.L.Bauer; holo:W’. 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 ‘holo’ is correctable under ICN Art. 9.10."
