Abstract
The presumed relationship between R antidysentericum (Eckl. and Zeyh.) Kostel., P. divisifolium Vorster, P. dolomiticum Knuth, P. griseum Knuth, P. plurisectum Salter, P. praemorsum (Andr.) Dietr., P. redactum Vorster, P. seneciodes L'Herit., P. tenuicaule Knuth, P. tragacanthoides Burch. and P. trifidum Jecq., based on keryelogical characters, is confirmed by palynologioal and rbcL gene sequence studies as well as phenolic compounds. These 11 species are placed in the section Jenkinsonia (Sweet) DC. ampl. J.J.A. van der Walt. The big variation in floral structure in the section is ascribed to convergent evolution and different pollination strategies. Taxonomic treatments of the section and species are presented.
