Chasmanthium latifolium by T.R. Soderstrom In 1950, the International Botanical Congress founded the International Association for Plant Taxonomy (IAPT), which initiated the journal Taxon. All proposals for conservation or rejection of scientific names, for suppression of botanical works, and for binding decisions on valid publication or confusability of names are now published in Taxon. The proposal number series for conservation/rejection proposals was started in 1955 and continues today; the numbering of other proposals only began in 2013. We are providing an index to all such proposals since the first ones appeared in 1892. The record for each proposal provides citations of any reports regarding its status and indicates the final disposition of the proposal, the representation, if any, in subsequent Codes, and any resulting entries in the Melbourne Code Appendices. For a full explanation of this search query, see our help file. [Dan Nicolson, March 2000-February 2009; John Wiersema, April 2009-present (7625 entries)].
