Abstract
Three new monotypic genera from the Cape Floral Region of South Africa are described.Calotesta Karis, a genus closely related to Metalasia and Alrichantha gemmifera (Karis, 1989) is characterized by its persistent, thick and strongly cutinized testa epidermis. The more distantly related Hydwidea has rather large, solitary white capitula and very thick‐walled apical pappus cells.Planea Karis is a new genus established for Metalasia schlechteri L. Bol., a species which must be removed from Metalasia (Karis, 1989).Planea has strongly carinate leaves with involute but characteristically flat margins and narrowly ovate apical anther appendage with a peculiar marginal pattern. Discussions concerning morphology and systematic position as well as illustrations and distribution maps of all taxa are provided.
