Petrocodon is a diverse genus of the family Gesneriaceae found in Southern China. Petrocodon formerly had few species, but recent genetic analysis has refined our understanding of the genus. Calcareoboea, Paralagarosolen, Dolicholoma and Tengia monotypic genera have been transferred to Petrocodon, as well as some Didymocarpus and Lagarosolen species.^[2]
