Petrocodon

Petrocodon is a genus of the family Gesneriaceae. It includes 51 species native to southern China and Indochina (Cambodia, Laos, Thailand, and Vietnam). 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.
