The article discusses the issue on the proposals which deals with original material and the typification of sanctioned names to be presented to the 18th International Botanical Congress in Melbourne, Victoria. It offers proposals which deal with the original materials of sanctioned names and their typification and the number of problems associated with sanctioning. It highlights errors in the proposals such as the use of terms and the suggested rewording.

The arguments towards resolving the Acacia nomenclatural controversy put forth by Thiele & al. (2011) are reviewed and rebutted. We argue that a truly pragmatic and, moreover, defensible and equitable alternative to accepting the retypification of Acacia Mill. with a conserved type would be to have the 2006 International Code of Botanical Nomenclature, excluding this retypification, serve as the basis for discussions at the Nomenclature Section of the Melbourne International Botanical Congress in 2011. We, and a large component of the international taxonomic community, and beyond, remain convinced that the minority rule voting procedure used at Vienna on Acacia was inappropriate, resulting in animosity that will without any doubt linger until this situation is rectified. Such a minority rule procedure has never in the history of Nomenclature Sections been implemented before. Exclusion of the Acacia retypification can be achieved through a democratic process by objecting to its inclusion when the printed (2006) Code comes up for adoption at the start of the Nomenclature Section. This is perfectly within the established process that has been used in past Section meetings. The integrity of the Code will suffer permanent damage if the retypification of Acacia Mill. with a conserved type is not removed from the ICBN, especially as it ended up there through a minority decision.

Ferdinand von Mueller (1825–96), the German-born Government Botanist of Victoria from 1853 until his death, and concurrently Director of the Melbourne Botanic Garden from 1857 until 1873, was a prolific systematic botanist, but also heavily involved in public educational activities. He conceived of the Garden as an educative place of recreation, but ultimately lost control over it. His loss did not stop his popular writing and lecturing, especially in areas related to the application of botany in horticulture, agriculture, and forestry. The structure of his introductory school text—very different from the intensely logical grammar-like botany texts of the period—owed much to his political masters, but it is characterized by careful attention to language and locality. Mueller's work represents a consistent and pervasive example of attention to the ‘public understanding of science’ that resonates with the concerns of early twenty-first-century funders of scientific research.

The article presents changes made to the International Code of Botanical Nomenclature at the XVIII International Botanical Congress held in Melbourne, Victoria in July 2011. To be effective on January 1, 2012, the changes concern publication in electronic data and the amendment of the requirement for a Latin description or diagnosis for names of new taxa to a requirement for a description or diagnosis in either Latin or English.
