Abstract

New combinations in Arnica L. and Monolopia DC. are made in light of evidence from a phylogenetic study of helenioid Heliantheae that each of the two genera is paraphyletic. Transfers herein of Whitneya dealbata A. Gray to Arnica and Lembertia congdonii (A. Gray) Greene to Monolopia allow for circumscriptions of Arnica and Monolopia that better reflect phylogenetic relationships.
