The taxonomic identity of the incompletely described Amorphophallus longispathaceus Engl. & Gehrm. has been a mystery for almost 109 years. Types were assumed destroyed during WWII, other than a sterile isotype at K, the recent discovery of a fertile isotype at NY, here designated the lectotype, has enabled the identity of this species to be clarified. Amorphophallus longispathaceus is conspecific with and takes priority over the more recent A. dactylifer Hett.
