This species is related to Chrysopsis hispida and C. columbiana, 
but differs from both in the larger heads ; it differs also from the 
former in the more copious pubescence and the more decidedly 
oblanceolate and petioled leaves; from the latter in the longer 
pubescence, the more copious resinous granules and the more 
decidedly petioled leaves.
