• Lectotype: "The holotype is R. Brown 6061 (number provided by Bennett) (BM); there are two sheets of this number at BM, one of which, from the "east coast" of Australia, is indicated by Clarke as the type specimen. The second sheet comes from Port Jackson."

• Comment: Although the specimen R.Brown 6061 at BM was listed by Smith as the "holotype", since the gathering consists of multiple specimens, this citation is here considered to constitute an effective lectotypification under ICN Art. 9.10 (Shenzhen Code, 2018).

• Comment: Lectotypification by Barrett et al. is superfluous under ICN Art. 9.19 (Shenzhen Code, 2018) due to previous effective lectotypification by Smith (1979).
