A way to handle ex and in parts of a taxon name

[camwebb]

Feature or enhancement

We are hoping to be able to semantically enter the ex and in parts of botanical names:

• Ex: "if the publication of the name by the initial author was invalid, the ex author was the author who subsequently published the combination validly.
• In: if initial author or ex author were responsible for the combination but were not actually the authors of the publication in which that combination first appeared, the author(s) of the publication should be added after in, usually with some bibliographic citation details following.)

E.g., Salix alaxensis subsp. glauca (Andersson ex DC.) R. Coville ex Jones in Smith 1923

Perhaps we should just enter this as a verbatim string?

Not sure...! It may be very tricky to implement. Thanks.

If I understand correctly, according to ICN, the author before 'ex' is optional and in many cases 'ex' is used confusingly with 'in' authors. At the moment, we do not cover this in TW model. If we take the formula "Author1 ex Author2 in Author3".

Author3 is the author(s) of the publication and covered as source Authors in TW.

Author2 is the author(s) responsible for the TaxonName description and covered as TaxonName Authors in TW.

Author1 is a reference to an earlier invalid name. We have an invalidating TaxonName relationship which links that invalid name to a valid name, if we need to semantically construct an author string based on a previously described invalid name, we need a special relationship (like a basionym, but distinct from it, indicating that the older name is the basis for the 'ex' relationship). What would be a correct name of this relationship of an invalid name to valid name to indicate that this name usage in a historical publication is the basis for the author citation?

"republished validly as"?

(I'm checking with a colleague too.)

@proceps A related observation: In TW, if I give a name both a Person author (e.g. Smith) and a Source (e.g. Jones 1975) , then look in Browse Nomenclature, the History section for that name use ex for the source. E.g. "Salix glauca Smith ex Jones, 1975". This is different from the behavior you cite above ("Author2 in Author3"), which would appear as "Salix glauca Smith in Jones, 1975"

I will look into it.

Been working on this more, in the Ephedra case.

We have an invalidating TaxonName relationship which links that invalid name to a valid name

Currently there is only an "ICZN set as invalid of". Could you please create a "ICN set as invalid of". This would help with encoding the name relationship, even before you have created a tool to semantically construct the correct "Author1 ex Author2 in Author3" string. Thanks.

Thanks! I see that was a lot of work.

I tested it in the Sandbox and it does exactly what we need: Name A1 ex A2 in A3 (see image). 🎉
