Synopsis of Proposals on Botanical Nomenclature - Vienna 2005. A Review of the Proposals concerning the International Code of Botanical Nomenclature Submitted to the XVII International Botanical Congress

Each personal member of the International Association for Plant Taxonomy is entitled to participate in the Preliminary Mail Vote on nomenclature proposals submitted to the XVIII International Botanical Congress, as stated in Division III of the International Code of Botanical Nomenclature (McNeill & al. in Regnum Veg. 146. 2006). Authors of proposals to amend the Code and members of the Permanent Nomenclature Committees (described in Div. III.2) are also entitled to participate, but no institutional votes are allowed. A voting form is inserted in this issue of Taxon and, if lost, available from www .iapt-taxon.org (sub Nomenclature). The voting forms (ballots) should be returned to the IAPT Office, Institute of Botany, University of Vienna, Rennweg 14, A-1030, Vienna, Austria, by 31 May 2011, so that they may be included in the tabulation to be made available to members of the Nomenclature Section of the Congress. The sessions of the Nomenclature Section, which will take definitive action on proposals, will be held in the Copland Theatre, Economics and Commerce Building 148, University of Melbourne (Parkville campus), Melbourne, Australia, from Monday, 18 July 2011 (09:00 hours) to Friday, 22 July 2011 (see http://www.ibc2011.com/ NomenclatureSection.htm). Each person registered for at least one full day of the Congress is entitled to enrol as a member of the Nomenclature Section. Registration for the Congress should be done in advance (see http://www .ibc2011.com/Registration.htm); the confirmation received will be the evidence of eligibility for registration for the Nomenclature Section, which will start during a welcoming reception on Sunday, 17 July, at 16:00 hours at The School of Botany Building 122 on the Parkville campus; Nomenclature Section registration will continue on Monday, 18 July at 08:00 hours at the Copland Theatre. Each member of the Nomenclature Section is entitled to one personal vote in the sessions. Personal votes can neither be transferred nor accumulated; one person never receives more than one personal vote. A member of the Nomenclature Section may be the official delegate of one or more institutions, thereby carrying their votes, but no one person is allowed more than 15 votes (including his or her personal vote). Official delegates are required to submit their credentials and to collect their voting cards when registering for the Nomenclature Section. Institutions are being advised of their allocation of votes in March 2011, in accordance with Division III of the Code. INTRODUCTION
