[Taxacom] North American flora types

[Richard Zander]

I don't remember that the code includes lectotypification in the rules for priority. If you think a lectotype should be chosen, go ahead and publish your choice following the rules. Someone scribbling "lectotype" on a specimen is scarcely a justification for following it.

Subject: [Taxacom] North American flora types

Many new taxa were described in the North American flora and in the volume I'm interested in (1907) the authors designate a holotype with a collector and collector number. However, they don't mention where the specimen is deposited. In this case there are several possible types in different herbaria. One of these specimens has been annotated at a later date that it is the holotype and another annotation on the same specimen suggests it is not (http://sweetgum.nybg.org/science/vh/specimen_details.php?irn=740487).
Tropicos seems to have decided that this specimen is the holotype ( http://www.tropicos.org/Name/23701364), but I can't see how they reached this conclusion, presumably just from the annotation.

In this case I suspect a lectotype should be formally selected. However, I wonder if perhaps I'm overlooking a note somewhere in the North American flora that would indicate where all the holotypes are held for this series.
This sort of case must be common for the taxa described there.

Quentin
