Description

The knobby green stems are fleshy and appear jointed at the internodes between segments. Often the segments are so short they are nearly round. The leaves appear as flaky scales scattered across the surface of the stems. The genus was named for the English botanist Robert Allen Rolfe.[3]

The seeds of iodinebush have been used as food in North America in prehistory.[4]
