Orontium /ɒˈrɒntiəm/, sometimes called golden-club,[2] is a genus of flowering plants in the family Araceae.

Two of the outcrops where the species was found are preserved volcanic ash beds which hosted long-term standing water.

The leaves of O. wolfei show a more complex vein structure than seen in O. mackii and have a hooded leaf tip similar to O. aquaticum.

The living O. aquaticum is endemic to eastern North America[2] and is found growing in ponds, streams, and shallow lakes.

Native Americans once ate the seeds and rhizome by drying them out and grinding them into a starchy substance.
