Oh, interesting. I can’t believe I didn’t see that!
Yeah, this is the problem then. I tested it again and marking sect. Goniostema as introduced will not mark descendent taxa (e.g., E. milii) as introduced either in the checklists or in the observations. I would like it where, if I change the occurrence status on sect. Goniostema to introduced, it applies it to E. milii and all other members of sect. Gioniostema.
Ideally, this would also work where, if a new taxon within that section were added to a place, it would automatically be considered introduced. As for implementation, perhaps something like: “automatically apply to descendent taxa unless taxon specifically marked as native” would offer the most flexibility?
Just to be clear, I think this is a good default, even though it caused me some difficulty.
