XIX International Botanical Congress, Shenzhen: report of the Nomenclature Section, 17th to 21st July 2017

Both botanical tradition and codes of nomenclature have held that specific epithets that are Latin phrases in the ablative case are unacceptable. Solanum fructu‐tecto, in Article 60 Example 41, has an epithet that is a phrase in the ablative case, so it too should be unacceptable. But because Article 23 now apparently prohibits only nomina specifica legitima (the polynomial phrase names, usually in the ablative case, used by Linnaeus and other early botanists), the status of Solanum fructu‐tecto and of other names with binomial epithets (Linnaeus's nomina trivialia) in the ablative case is unclear. The Code should return to tradition and prohibit specific epithets in the ablative case.

A special‐purpose Committee on DNA Sequences as Types was established at the XIX International Botanical Congress (IBC) in Shenzhen, China, in 2017, with a mandate to report to the XX IBC in Madrid in 2024 with recommendations on a preferred course of action with respect to potential amendments of the International Code of Nomenclature for algae, fungi, and plants to allow DNA sequences as types. This is the first in an expected series of papers from the Special‐purpose Committee on this issue. We set out the background to the establishment of the Committee, explore key issues around typification that are pertinent to the question of DNA sequences as types, enumerate pros and cons of allowing DNA sequences as types, and foreshadow options for future discussion and potential recommendations.

While these were originally intended to deal with fungi only, a friendly amendment from the floor at the Nomenclature Section extended them to all organismal groups covered by the Code (Lindon & al., 2020). The proposals were rejected at the Nomenclature Section, and the issue was referred to the present Special‐purpose Committee, with a mandate to report on the matter to the XX IBC (Wilson, 2019; Lindon & al., 2020).…”

Report of the Special‐purpose Committee on DNA Sequences as Types, established at the XIX International Botanical Congress in Shenzhen, China

A Special‐purpose Committee on DNA Sequences as Types was established at the XIX International Botanical Congress (IBC) in Shenzhen, China in 2017, with a mandate to report to the XX IBC with recommendations on a preferred course of action with respect to DNA sequences as potential types under the International Code of Nomenclature for algae, fungi, and plants. This report provides a synthesis of the deliberations from the Special‐purpose Committee on this issue. We discuss two potential options for dealing with the problem that many species, especially of microfungi and microalgae, can be discovered and delimited using eDNA sequencing but cannot currently be formally named due to the requirement in the Code that either a specimen or illustration be nominated as holotype. One option is to expand the definition of “type” to include DNA sequences, while a second option would allow some taxa to be named without types, the application of their names instead being determined using a DNA sequence. This report should be read in concert with two formal proposals for potential amendments to effect these options, published in this issue of Taxon.
