There is only one species in this genus, and it is the only one in the family that occurs in eastern North America (as well as in the west, to which the rest of the family is native). Our species is distinct among our dicots in its completely 3-merous flowers: 3 sepals, becoming much larger than the 3 persistent tiny white petals; (3 or) 6 stamens; and (2–) 3 carpels. The very deeply pinnately lobed leaves will separate it readily from any monocot with which it might be confused.
