Amorphophallus plants have a tuber, from which a single inflorescence issues, followed by a single leaf. The spadix[?] has female flowers at the bottom, then male flowers, then a blank area. In some species the spadix strongly resembles a penis, hence the name.

The titan arum, the world's biggest flower, belongs to this genus; a runner-up is A. gigas, which is taller, but has a somewhat smaller flower. A. konjac tubers are used to make konjaku[?], a Japanese thickening agent containing glucomannan[?].

Some species are called voodoo lily[?], as are some species of Sauromatum[?] (also in Araceae).
