Abstract. Of the genus Amorphophallus, four species from Taiwan are recognized—A, henryi N.E. Br., A. hirtus N.E. Br., A. kiusianus (Makino) Makino, and A. paeoniifolius (Dennst.) Nicolson. The first two species are endemic to Taiwan. Amorphophallus gigantifiorus Hayata and A. niimurai Yamam., both from Taiwan, are reduced to the synonymy of A. paeoniifolius and A. henryi, respectively. Arnorphophallus kiusianus is newly recorded in Taiwan and the mainland Chinese A. sinensis Belval is here reduced to its synonymy. Biogeographic considerations and phylogenetic affinities of the species are discussed.
