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.
