POWO has merged this into oriental false hawksbeard (Youngia japonica), specifically to the subspecies Youngia japonica subsp. elstonii (Hochreutiner) Babc. & Stebbins; we have yet to review this merge.
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.
