Other: The genus name, “Krascheninnikovia”, honors Stephan Petrovich Krascheninnikov (1713-1755), a Russian botanist and professor of Natural History. Krascheninnikov accompanied the Danish explorer Vitus Jonassen Bering on his Great Northern Expedition to explore easternmost Siberia (1733-1743), one of the largest scientific ventures the world has ever known. The genus name, “Ceratoides”, is from the Greek “ keras ” which means “a horn”. The genus name, “Eurotia”, is from the Greek “euros”, "mold" because of the hairy covering.

The species name, “lanata”, means “wool-like” referring to the hairy branches, leaves and fruit.

This plant is a valuable winter browse plant for wildlife and livestock.

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.
