Discussion
Subspecies incompta varies. It could be (and has been) subdivided. The variation found within one population, as well as from one part of its range to another, makes the recognition of discrete taxa difficult as well as questionable. The morphologic variant treated as Artemisia lindleyana by some authors may warrant infraspecific status.
