Talk:Aristolochia

Generic circumscription

Aristolochia s.l. is monophyletic, but a number of botanists propose that it be dismantled in favour of at least 4 segregates. The first of the proposed segregates is a resurrected Isotrema Raf., Amer. Monthly Mag. & Crit. Rev. 4(3): 195. (1819) (Zhu et al., 2019). However, this has not been accepted by all authorities, as it may be superfluous, symptomatic of a move to genus inflation and at the moment is only part of an incomplete project. WS has to adopt a conservative approach until consensus is more or less accepted (Govaerts et al. 2022). Andyboorman (talk) 17:31, 23 June 2022 (UTC)

Please do not unilaterally create segregates from Aristolochia s.l. without at least going to the pump, as they could be reverted or dismantled. There is already a number of orphan Isotrema species that will need to be evaluated and possibly moved. Thanks Andyboorman (talk) 17:37, 23 June 2022 (UTC)

Given that it has been nearly five years since a small group of Chinese botanists proposed dismantling monophyletic Aristolochia s.l. without gaining much consensus, it seems appropriate to move those few species of Isotrema to their equivalents in Aristolochia.

Isotrema is meanwhile listed as accepted by Catalogue of Life (World Plants) and by GBIF, but not yet by POWO. Thiotrix (talk) 15:59, 20 March 2026 (UTC)

Thus, it is a classic disputed taxon and logically needs it own page as do its species equivalences in Aristolochia s.l. I do not think that POWO will accept the segregation, but you could ask for an opinion, as I did a few years ago. Andyboorman (talk) 16:06, 20 March 2026 (UTC)
