Genus: FraseraView DescriptionDichotomous Key

Habit: Perennial herb (non-flowering rosettes preceding flower-stems, plants dying after flowering in Frasera albomarginata, Frasera parryi, Frasera puberulenta, Frasera speciosa, and Frasera umpquaensis; non-flowering rosettes appearing with flower-stems in others).
