Discussion

At flowering, phyllaries of Pinaropappus roseus are pale green with margins suffused with pink. On fresh specimens, the dark brown tips are distinctive. Specimens from the mountains of southeastern Arizona and southwestern New Mexico with stems leafy beyond the middles have been recognized as </i>var.<i> foliosus; that trait appears to be widespread and part of the normal range of variation for the species.
