Genus: EriastrumView DescriptionDichotomous Key

Habit: Glabrous to woolly, glandular or not. Stem: generally erect. Leaf: cauline, alternate, generally pinnate-lobed or simple; lobes generally linear or lanceolate. Inflorescence: head-like, bracted, generally densely woolly; bracts leaf-like; flowers sessile. Flower: calyx lobes unequal, generally woolly; corolla radial or bilateral, funnel-shaped to salverform; stamens equal or not, anthers generally sagittate, pollen white or blue; style included or exserted.
