Would you like to tell me about the above taxonomic issue in Taiwan?
I want to swap Rubia akane into Rubia argyi, so I'd like to know about infraspecies of R. akane.
@utchee
Thank you for your reminder.
Both R. akane and its variety R. akane var. erecta are accepted by Flora of Taiwan 2nd edition, which is the most widely accepted literature by our native users.

As shown, we do not use the name R. nankotaizana which is considered as a synonym of R. akane var. erecta.
I have also read the note in R. argyi in FOC:
http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=250096612
I agree with treating R. akane as a synonym of R. argyi. Consequently, the name R. akane var. erecta should also be changed into R. argyi var. erecta to retain its variety status, but this new recombination has never been proposed by any authors.
I think the variety gets its diagnostic features (higher elevation, erect habit, more cordate leaves) from its parent species, and local users in Taiwan may have been used to telling two taxa apart rather than lumping them together.
It's a dilemma between transferring to the more widely accepted name and retaining a variety status without a published name.
In my point of view, both transferring to R. argyi (which means cancelling the variety taxa) and retaining the current status are acceptable. If there's any new data supporting any of them, we can change that again.
Hoping there will be taxonomists revising R. akane (R. argyi) in Taiwan, figuring out the whether its variety is conspecific or not, and elaborate a treatment about this issue.
@galanhsnu Thank you for your checking.
After sending "@" other Japanese curator/users for confirmation, I'll merge these 3 taxa to Rubia argyi.
I also always feel dilemma between necessity of local taxa and taxon arrangement by POWO globally. I hope that someone will advance further taxonomic studies, too.
@harumkoh , @genjitsu , @keitawatanabe
Any objections about merging Rubia argyi (アカネ)?
直立紅藤草(Rubia akane erecta) seems the tropical plant and I don't know what the plant looks like. So I can't say anything about this plant... :(
@harumkoh Thank you for your confirmation.
galanhsnu and me have been discussed about the variation usage in Taiwan, then concluded that 3 species and vatiation will be merged into Rubia argyi.
I sent @ to you because Rubia argyi is also distributed in Japan. I will make draft merging R. argyi, R. akane and R. akane var. erecta into R. argyi, so if further discussion is needed, please note this page.
I make a draft about taxonomic merge into R. argyi.

@mutolisp Would you like to tell me about taxonomic status of this variation in Taiwan?
I flagged about synonym at parent species here.

Rubia akane var. erecta is treated a synonym of R. nankotaizana Masam. in YList (consensus checklist in Japan.)

But, R. nankotaizana is a synonym of R. argyi in POWO.

If it is a useful variation for native countries users, I think we should handle it with care.
