replaced synonym: Earlia excelsa F.Muell. legitimate taxonomic synonym: Thyrsacanthus earlii F.Muell. nom. inval., pro syn.

• Comment: The name Graptophyllum earlii F.Muell. var. earlii is listed by A.D.Chapman, Austral. Pl. Name Index 1459 (1991), but this autonym does not exist, in accordance with ICN Art. 27.2 (Melbourne Code, 2012).
• Comment: nom. illeg., nom. superfl., as the epithet excelsum was available in Graptophyllum in 1867 and thus ought to have been adopted by Mueller.
