It resembles P. xanthocephalus subsp. xanthocephalus but differs from it by having a densely greyish-floccose-tomentose indumentum on both sides of leaves; undivided basal and lower cauline leaves; oblanceolate and wider median cauline leaves; hemispherical and wider involucres; denticulate and shiny white appendages; white flowers; shorter central floret; purplish achenes; and longer pappus. The chromosome number of P. avajiqensis, counted from root tips, is 2n = 2x = 30.
