Other: This genus is named for Artemisia, queen of Caria (ca 400 B.C.), a botanist and scholar, who might have been named for the Greek goddess Artemis. Caria is now a part of Turkey . The species name, “ludoviciana”, means either "of or from Louisiana” or “of St. Louis” describing part of the plant's range. Thomas Nuttall (1786-1859) described this species in his The Genera of North American Plants of 1818. He visited the Mandan villages in what is now North Dakota in 1810 and 1811.
This family is the most advanced and complex of the dicots. The family is rich in oils and resins and is found in every part of the world, but is infrequent in the tropical rainforest. Aquatic or semi-aquatic species are also uncommon.
