Fertile or unisexual florets 2-lipped. We have no really hardy species belonging to this division, but there are two or three Chilian species of recent introduction which may be regarded as nearly so. Mutisia decurrens and M. speciosa are climbing plants with pinnatifid leaves terminating in a tendril, and orange or red flower-heads on long peduncles. Proustia pyrifolia, another climbing species, is remarkable for its beautiful rosy pink pappus.
