deviate from POWO? or merge with B. pilosa?

Not Resolved


Bidens odorata Cav. is a synonym of B. pilosa in POWO:

copying over comment from @bodofzt:

In Mexico, CONABIO chooses to maintain the Bidens pilosa complex as separate species:
B. alba: Up to 8 ligules that are notably longer than wide. Relatively short external (green) bracts. See
B. pilosa: Absent or reduced ligules. At least some fruits with three awns instead of two. See
B. odorata: 5 ligules that are barely longer than wide. Longer external bracts. See

POWO does not indicate what is the reason or based on what document is that it does not accept this species.
I need to investigate thoroughly what is the current status of this complex to give a better opinion, although personal mine is that they should all be one.

@bouteloua @oscargsol As this complex (and entire genus) is a taxonomic mess, I'd suggest creating a "Bidens pilosa complex" taxon for the above species. Right now observations are just scattered amongst them all by people going off computer-vision or the species they see being reported dominantly in their area.
