REMARKS. Pham et al. [2015] showed the T. petiolatum distribution in Vietnam based on an electrical list of the genus produced by Pulawski [2015], but did not mention the specific locality of the distribution (provincial level). Therefore, we list in the present study the species and give its specifically distributional locality.
