Other: The genus name, “Asclepias”, refers to “Asklepios”, a Greek physician and an authority on the medicinal use of plants and who according to Greek Myth could bring the dead to life. Hades fearing a loss of employment, convinced his brother Zeus to kill Asklepios with a bolt of lightning. The species name, “cryptoceras”, is from “cryptos” which means "hidden" and “keras” which means "horn or antlers".
