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.
