Discussion

Parasenecio auriculatus occurs chiefly from northern Japan and Manchuria northward; it barely enters the flora area in the western Aleutian Islands, as far east as Kiska Island. The species is variable; some floristicians have recognized infraspecific taxa. Plants in the flora area have been treated as var. or subsp. kamtschatica (-us) in various combinations; current opinion suggests that they be recognized simply as P. auriculatus.
