"Doubtful species: Hypopterygium rotulatum (Hedw.) Brid., Bryol. Univ. 2: 713 (1827) Leskea rotulata Hedw., Sp. Musc. Frond. 213, t. 51, figs 8–13 (1801). T: “Insulae meridionales”, coll. unknown [absent from the Hedwig-Schwägrichen herbarium in G; not located elsewhere]; lecto: The illustrations in Hedwig (1801), fide J.D.Kruijer, Blumea, Suppl. 13: 250 (2002). Hedwig’s description and illustrations of H. rotulatum do not differentiate this taxon from other Hypopterygium species, and they have caused considerable confusion (Kruijer, 2002). Specimens from Australia that had been identified as H. rotulatum proved to be either H. didictyon or H. tamarisci. H.N.Dixon’s (Bull. New Zealand Inst. 3(5): 296, 1927) H. rotulatum agrees with H. tamarisci. Reports of H. rotulatum in G.A.M.Scott & I.G.Stone (The Mosses of Southern Australia 396, 1976) are referable to H. didictyon and H. tamarisci." The illustrations in Illustrations: K.W.Allison & J.Child, Mosses of New Zealand pl. 29 (1971) are of H. didictyon.
