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. This database, which succeeds the "Proposals and Disposals" database initiated by Dan Nicolson in 2000, contains records of all such proposals and their histories since the first ones appeared in 1892, and two reports are available from the data. A Proposals report details the history of selected proposals, providing citations of all Nomenclature Committee reports regarding their status, and indicating the final disposition, the representation, if any, in subsequent Codes, and any resulting entries in the Melbourne Code Appendices. A Code Appendices report reproduces all entries matching any set of search criteria within the content of Melbourne Code Appendices II-VIII. For a full explanation of these criteria, see the help file. [Dan Nicolson, March 2000-February 2009; John Wiersema, April 2009-present (7625 entries)].
