Other: The genus name, “Atriplex”, is the Latin name for the plant and the species name, “confertifolia”, means “with flowers pressed together” referring to the tight floral clusters.

Plants in this family are generally weedy, but beets and spinach are members of this family. The family is called the goosefoot family because the leaf shape may look like a goose's foot.
