Plants acaulescent, terrestrial, lactescent. Leaves spiral, deeply 2-cleft, re-sembling those of many species of Carludovica. Spadix immediately subtended by 5-7 petalaceous or somewhat foliaceous spathes. Staminate and pistillate flowers arranged in separate, alternating cycles, those of each cycle adnate and more or less completely confluent; staminate flowers naked; pistillate flowers en-closed by 2 rims of fleshy tissiue representing the concrescent perianths, staminodia numerous, short. Fruit a syncarp consisting of the various fleshy cycles of pistil-late flowers, somewhat resembling a large screw.
