A new species, Typhonium vermiforme V. D. Nguyen & Croat (Araceae), is described from living materials collected from Quang Binh Province in central Vietnam. It is similar to T. bachmaense V. D. Nguyen & Hett. and T. trilobatum Schott, but differs from the first species by its much shorter spathe (ca. 9 cm long) and the distinctive, filiform and intertwining staminodes. It differs from the second species in having a solitary leaf and a pedate leaf blade.
