Abstract
A recent molecular phylogenetic study of the predominantly Mexican Brickellia resolved issues regarding its generic circumscription, but a new infrageneric classification remains to be formalized. We propose to recognize as sections nine clades identified as monophyletic based on molecular data. Three of these clades have been previously recognized as distinct genera, Barroetea, Kuhnia, and Phanerostylis, and require names at the sectional level. The remaining six sections have names available from previous taxonomic work, but two of them require validation at the sectional level, and all have a different species composition compared to previous studies.
