In this treatment, Chrysothamnus humilis is limited to plants with at least some of the inflorescence clusters equaled or overtopped by one or more of the terminal stem leaves. Plants resembling C. humilis but with the heads standing well above the upper leaves are better placed in C. viscidiflorus ssp. puberulus.
