Zanthoxylum, comprising about 200 species in the world, is a large genus of the family Rutaceae. Nine species were recorded in the 2nd edition of Flora of Taiwan. In the course of our botanical inventory, Z. acanthopodium DC., heretofore unknown in Taiwan, was collected from central and eastern part of the island. Z. acanthopodium is easily distinguished from other congenors by leaf rachises with conspicuous wings, and secondary veins of leaflet adaxially blades evident. In this report we provide a description and colored photographs taken from the wild to aid identification.
