The essential oil of Mosla methylchavicolifera FUJITA (Labiatae) was examined by gas chromatography and infrared spectrometry, and its components were compared with those of Agastache rugosa O. KUNTZE. The similarity of components of these two essential oils will show the same stage of appearance of homologous element in the formation of essential oils controlled by the homologous series of genes. These phenomena are also explained by assuming that parallel evolution of essential oil formation is in the same stage.
