Names in specified ranks included in publications listed as suppressed works (opera utique oppressa; App. VI) are not validly published. Proposals for the addition of publications to App. VI must be submitted to the General Committee (see Div. III), which will refer them for examination to the committees for the various taxonomic groups (see Rec. 34A; see also Art. 14.12 and 56.2).
When a proposal for the suppression of a publication has been approved by the General Committee after study by the committees for the taxonomic groups concerned, suppression of that publication is authorized subject to the decision of a later International Botanical Congress (see also Art. 14.16 and 56.4).
When a proposal for the suppression of a publication under Art. 34.1 has been referred to the appropriate committees for study, authors should follow existing usage of names as far as possible pending the General Committee’s recommendation on the proposal (see also Rec. 14A and 56A).
