In the following lists the nomina conservanda have been inserted in the left column, in bold-face italics. Synonyms and earlier homonyms (nomina rejicienda) are listed in the right column. Conserved names are listed alphabetically within the major groups:

  1. Algae
    1. Bacillariophyceae (incl. fossil diatoms)
    2. Bodonophyceae
    3. Chlorophyceae
    4. Chrysophyceae
    5. Cyanophyceae
    6. Dinophyceae
    7. Euglenophyceae
    8. Phaeophyceae
    9. Rhodophyceae
    10. Trichomonadophyceae
    11. Xanthophyceae
  2. Fungi
  3. Bryophyta
    1. Hepaticae
    2. Musci
  4. Pteridophyta
  5. Spermatophyta
    1. Gymnospermae
    2. Monocoyledones
    3. Dicotyledones
  6. Fossil plants (excl. diatoms)

orth. cons.  orthographia conservanda, spelling to be conserved (Art. 14.11).
typ. cons.  typus conservandus, type to be conserved (Art. 14.9; see also Art. 14.3 and 10.4); as by Art. 14.8, listed types of conserved names may not be changed even if they are not explicitly designated as "typ. cons."
typ. des.  typi designatio, designation of type (Art. 10.5); used with names that became nomenclatural synonyms by type designation.
vide  see; usually followed by a reference to the author and place of publication of first type designation (Art. 10.5); also used (as "etiam vide", see also) for cross-reference to another relevant entry.
(H) homonym (Art. 14.10; see also Art. 53), only the earliest being listed.
(≡) nomenclatural synonym (i.e., homotypic synonym, based on the same nomenclatural type as the conserved name; Art. 14.4), usually only the earliest legitimate one being listed (but more than one in some cases in which homotypy results from type designation).

Nomenclatural synonyms of rejected names, when they exist, are cited instead of the type. Nomenclatural synonyms that are part of a type entry are placed in parentheses (round brackets).

(=) taxonomic synonym (i.e., heterotypic synonym, based on a type different from that of the conserved name), to be rejected only in favour of the conserved name (Art. 14.6 and 14.7).

Some type citations are followed by an indication of heterotypic synonymy (the supposedly correct name and its basionym, if any), reflecting current taxonomic opinion and in no way binding for nomenclatural purposes.

Some names listed as conserved have no corresponding nomina rejicienda because they were conserved solely to maintain a particular type, because evidence after their conservation may have indicated that conservation was unnecessary (see Art. 14.13), or because they were conserved to eliminate doubt about their legitimacy.
