I made this deviation to handle the existing sections and subsections within Solidago https://www.inaturalist.org/taxon_framework_relationships/464705
and this flag to discuss the rationale behind which species belong in which section/subsection

Updated subgenera and sections to Semple & Beck (2021).

Looks good to me. Thanks, @rynxs

Oh no - I wouldn't have made these changes until Semple & Beck at least published their molecular phylogeny. They say it's about to be published in 2021, but it's 2023 and I haven't seen it.

But anyway - you also made substantive changes to the meanings of subsections, particularly subsections Venosae and Triplinerviae, both of which, in their new senses, have had commonly-observed species removed from them to new subsections. Shouldn't this have been handled with a taxon swap? Or was it swapped? If so, I can't find the inactive taxa.

What has now become of my many subsection Venosae and subsection Triplinerviae IDs? They were all made in the old, broader senses of those taxa, not the new, narrower senses.

I wish I could give examples, but I cannot figure out how to search for my subsection-level IDs in a way that excludes my IDs of child taxa. (Which also means that I have no idea how to correct them, if necessary, given the new senses of Venosae and Triplinerviae!)

Subsection Triplinerviae was not changed at all, I believe, just moved to a different subgenus. For subsect. Venosae, I changed the rank from subsection to section and created a new subsect. Venosae.

If you do find any issues, let me know. Subgenera/section/subsection/complex taxonomy is pretty easy to fix.

No, both subsections have been substantively changed. S. gigantea, for example, used to be in subsection Triplinerviae. It is now in a different subsection. This changes the meaning of every previous ID of subsection Triplinerviae.

Good approach with the Venosae change, though! That's a relief.

Another red flag - but presumably with far fewer ramifications - the meaning of subsection Humiles has also changed substantively, with some of its previous members now distributed into subsection Erectae. If anyone applied the ID "Humiles" to these species (rare ones in the SE USA) it is now misapplied.

Ah, I forgot about that somehow. Did you want subsect. Triplinerviae swapped into Solidago or subg. Pleiactila?

Posted by rynxs about 1 year ago

I think all the former Triplinerviae species are in sect. Unilaterales, right? Shouldn't we bump them up only as far as necessary?

Posted by ddennism about 1 year ago

I'm on a roll (of forgetfulness)! Forgot to list sect. Unilaterales, but yes, that would be the preferred swap. Probably shouldn't have been doing this mid-class, but now I'm out.

Subsections Triplinerviae and Humiles have been elevated to their respective higher taxa and replaced.
