Nomenclature, ed. 3
(Cambridge Rules).  Based on the Proceedings.

The Synopsis is different from that of any other Congress. The Red
Book (Synopsis of proposals) only offers a synoptic view of the
proposals (without comments by the Rapporteur): the evaluating
comments can be found in the Grey Book (Preliminary opinions)
which provides the recommendations of ten eminent botanists who
had been sent the Red Book and had responded with a vote in
favour or against. Offered separately are the votes and comments
by Barnhart, which came in late. In addition, the Grey Book also
has some proposals that came in late.

The Section decided that all proposals that had received four-fifths
or more no-votes in the Grey Book were automatically rejected.

At this time, the format  “Art. B 11”  was used to number proposals.
For convenience sake, this has been converted here to the latter-day
format  “Art. 11 Prop. B”.  The abbreviations  “PB”  and  “Myc”
in the Grey Book indicate that the number of votes received was
inadequate to formulate a recommendation on a proposal pertaining
to palaeobotanical nomenclature or mycology, respectively (no
action was taken by the Section on these proposals, either). An
asterisk indicates that the Grey Book has an additional comment
(or comments), not just a vote.

                    the Bureau recommended that this proposal be rejected but that

Art. 35 - Prop. A  :   + * Hochreutiner,  Art. 35.   Barnh.: +

                    was accepted as amended (the Bureau); the change to Art. 35 to

           to be abbreviated:

             “In citation of literature ‘in’ should be inserted after the name of the
               author if the citation refers to a periodical or other serial publication,
               or if it is a work by another author.”

Rec. XXXIIqui. (new)  :   + * Rehder,  Rec. XXXIIqui.   Barnh.: – *

           was accepted as amended (the Bureau), to read:

             “If a name cited in synonymy applies only in part to the group under
               which it is cited, it should be made clear whether the synonym cited
               includes the type, and in that case the words pro parte typica, (p. p.
               typ.) should be appended; in more exact citations the parts excluded
               or those belonging to the group in question should be cited, or the
               name of the author who changed the circumscription of the group
               should be added, preceded by ‘emend.’.”

Art. 55 - Prop. A  :   + * Sprague,  Brit. Bot. 17bis.   Barnh.: +

                     was accepted as amended (Sprague), to read:

                       “When, on transference to another genus or species, the epithet
                         of a subdivision of a species has been applied erroneously in
                         its new position to a different subdivision of the same rank,
                         the new combination must be retained for the plant on which
                         the former combination was based, and must be attributed to
                         the author who first published it.”

                         followed.”

Art. 70 - Prop. E  :   + * Verdoorn,  Brit. Bot. 29.   Barnh.: +

                     it was suggested (Sprague) that in view of the small number of
                     such names (masculine generic names based on a personal name)
                     it would be better to deal with these by conservation of the
                     desired spelling, rather than by a special rule. It was agreed
                     to reject the proposal and to refer the five generic names
                     concerned (Herberta, Marchesinia, Nardia, Pallavicinia, and
                     Riccardia) for conservation.

                    referred to the Executive and Editorial Committees. Also, the
                    following motion (Ramsbottom) was accepted:

                      “That the President and Secretary of the Executive Committee
                        of Nomenclature be ex officio members of all nomenclature

Miscellaneous

•  It was proposed (Rendle) and accepted that only matters left
    over from the present Congress, or new propositions, should
    be allowed to be proposed at the next Congress.

•  It was moved (Lanjouw) that a proposal to the Cambridge
    Congress, Art. 37ter (Rec. Syn. p. 41) ([   ]), be considered; this
    was accepted as amended (Robyns), to read:

     “A name of a taxonomic group is not validly published unless it
       is definitely accepted by the author who publishes it. A name
       proposed provisionally (nomen provisorium) in anticipation of
       the eventual acceptance of the group, or of a particular
       circumscription, position or rank of a given group, or merely
       mentioned incidentally is not validly published.”

    The example was brought forward (Robyns) of Cymbopogon
    Bequaerti and Andropogon Bequaerti and discussed; such
    alternative names were to be allowed.

•  The following four resolutions proposed by the Algologists were
    adopted:

    1. In describing new species of Algae, special importance should
        be attached to the provision of illustrations and to maintenance
        of cultures of the species concerned.
    2. The desirability of adopting further monographs as the starting
        points of particular groups of Algae, as in the Oedogoniaceae,
        should be investigated.
    3. A list of nomina dubia of species, genera and families should
        be prepared, and also lists of nomina conservanda and
        rejicienda of genera and families.
    4. The desirability of retaining the Latin language for diagnoses
        of new Algae should be investigated.

•  As to the proposals on fossils, the Section of Palaeobotany met on
    September 3rd, and decided unanimously that additions should be
    made to the rules and recommendations for the following objects:

    1. To recognize as taxonomic groups, organ genera and artificial
        or form genera.
    2. To ensure that the names originally given to detached organs or
        parts of plants shall only be used in their original significance
        and shall not be employed in the designation of different organs,
        or of the plant as a whole.
    3. To provide for the naming of an entire plant when it has been
        possible to reconstruct it by the association of its different
        organs.
    4. To define how the names of the artificial genera are to be used.
    5. To set up a permanent committee to consider the interpretation
        of the rules; to adjudicate in cases of dispute or difficulty; to
        draw up lists of Nomina generica conservanda; and to make
        such further recommendations as may prove necessary,
        including rules for the determination of types.

    Wording and arrangement to be left to the Secretary, Hamshaw
    Thomas, the whole to be printed as an appendix.

•  As to the proposals on mycology, it was stated (Ramsbottom) on
    behalf of the Committee for Fungi that separate subcommittees
    would be appointed to investigate the effects of the various
    proposals (Art. 20 Prop. A, B, C, E, and F, Art. 57 Prop. A).

•  An Editorial Committee for a Supplement of the International
    Rules of Botanical Nomenclature was appointed (three persons,
    one for each language) instead of a full Editorial Committee.

 
Committees

•  A Special Committee to report on the effects of the adoption of
    Art. A 19 (dealing with the proposed suppression of certain works)
    was appointed.
•  A Special Committee for Nomenclature of Economic Plants was
    appointed to draw up a list of names of economic plants according
    to the International Rules; this list to remain in use for a period of
    ten years.
•  The appointment of a Committee to draw up an Appendix on
    Regulations for determining types (the App. I proposed at
    Cambridge) was referred to the Executive Committee.
