Introduced or Not Present

This map is based on our research. We have checked its accuracy to Level 3 ecoregions. Although this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.


Sometimes this taxon is considered a variety Achyranthes bidentata var. japonica; POWO does not even recognize such a variety and instead lumps this in with Achyranthes bidentata, which it says has also been introduced to Canada. We have not yet seen or reviewed the justification for this merger so for now are keeping this taxon separate as most sources do.
