Genera: Saintpaulia, Streptocarpus

Molecular phylogenies of the genus Streptocarpus based on the ribosomal DNA internal transcribed spacer (ITS) sequences show that the genus is paraphyletic; other African genera Saintpaulia, Schizoboea and Linnaeopsis are nested within Streptocarpus. The genus Saintpaulia has evolved from a caulescent African Streptocarpus species in subgenus Streptocarpella.
