A new species of Amorphophallus is described and illustrated here, from the province of Camarines Norte, Luzon island, the Philippines. The new species, A. caudatus, is morphologically close to A. luzoniensis in having a verruculose spadix, a similar spathe shape, and similar size of the ovary. However, the new species is distinct by its larger leaves, a longer peduncle, a longer and wider spathe, an inflated, verruculose spadix which strongly narrows to the caudate upper half, a fusiform ovary, and a shorter style with a shallowly 2–3‐lobed stigma. The peculiar shape of the spadix with its verruculose inflated base and caudate upper half is unique amongst Philippine Amorphophallus species.
