From J. Arnold Arbor. 20: 49 in 1939: For years, the name Cinnamomum pedunculatum has been attached to a variety of specimens from all over southeasterrn Asia. It has not been clear exactly what did comprise the true species. Nakai first established the identity of Laurus pedunculata Thunberg, upon which Nees, apparently, without having seen the specimen, based C. pedunculatum. The specimen, however, as Nakai states, is Hedyotis pedunculata (Thbg.) Nakai… Cinnamomum pedunculatum of Nees, now known as C. japonicum, occurs only in Japan, Formosa, Corea and the Liukiu Islands. There are records of misnamed C. pedunculatum from China, but these specimens are found to be C. Burmanni.
