[swcoloradowildflowers.com] Taxonomy: Thomas Nuttall collected the first specimen of this strangely lovely plant "in humid situations on the plains of the Missouri, near Fort Mandan" in 1812 (as quoted in Intermountain Flora) and named it in his 1818 Genera of North America Plants. Nuttall called the genus "Orthocarpus" because of its straight ("ortho") fruit ("carpus"). "Luteus" is Latin for "yellow". (link added by Mary Ann Machi)
