Orontium aquaticum /ɒˈrɒntiəm/, sometimes called golden-club,[2] floating arum, never-wets or tawkin,[3] is a species of flowering plants in the family Araceae.

[4] O. aquaticum is endemic to the eastern United States[2] and is found growing in ponds, streams, and shallow lakes.

The sheath was originally classified by Adolf Engler as a spathe due it being the last foliar piece before the spadix.

However, in a 1988 paper Thomas Ray argued that the structure was misidentified by Engler and was actually a sympodial leaf.

This interpretation was determined based on observations of morphological charactestics namely the appearance of a two-keeled bracteole and its positioning.
