Other info. - This species is a real treat, but rare in Missouri, currently known only in two counties in the far north of the state. Although there are very old collections from the St. Louis area, the species is probably extirpated from that region. The plant is far more common to our north. It is easily recognized by the upright posture of the flowers and the red-orange, brown-spotted perianth.
