Nabalus is a genus of Asian and North American flowering plants in the tribe Cichorieae within the family Asteraceae.[1][2]
Nabalus is now considered the correct name for a group of plants in North America that were formerly considered to be members of Prenanthes, and were included in that genus in the Flora of North America treatment.[3] Common names for the genus include "rattlesnake root" and "white lettuce." The latter reflects its close relationship to lettuce (Lactuca sativa) but having flowers that are whitish or purplish-white in some species. Many (perhaps all) of the species are monocarpic perennials, in which an individual plant may live for multiple years in a vegetative condition but then will die after flowering and fruiting.[4]
