Cinnamomum micranthum HAY. and C. Kanahirai HAY. in Formosa are vicarious species and contain different kinds of the constituents of essential oils which discriminate the both species in each other. The characteristic constituents of C. micranthum are decyl aldehyde and pentadecyl aldehyde, while that of C. Kanahirai is terpinenol-(4). C. Kanahirai HAY. was thus confirmed not to be a synonym of C. micranthum Hay.
