Other: The genus name, “Castilleja”, honors Domingo Castillejo, an 18th century Spanish botanist. The species name, “linariifolia”, means “with leaves like Linaria” referring to the narrow leaves which resemble those of “Linaria (Toadflax)”, another member of the Figwort Family.
The family is important because of many ornamentals and cardiac glycosides that can be derived from foxglove.
