The distinction between this species and the variable I. leptolepis is not clear. In this treatment I. tomentosa has been circumscribed principally on its possession of woolly-cobwebby involucral bracts. I. leptolepis has glandular-hairy bracts though in foliage it may be as woolly as I. tomentosa.
