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 are now published in Taxon. The proposal number series was started in 1954 and continues today. We are providing an index to the names proposed for conservation or rejection since the first proposals in 1892. The record for each name provides the citation for the relevant publications and indicates the final disposition of the proposal. For a full explanation of this search query, see our help file.
