Though sometimes rather small, this is extremely pretty. In the Grand Canyon, on the plateau, it is about a foot tall, with rather leathery, brownish-green leaves, mostly from the root, and from five to twelve flowers in a cluster. They measure nearly an inch across and are brilliant and iridescent in coloring, as except for two small whitish petals, they are the deepest, brightest blue, exquisitely tinted with violet, with brown anthers. At Tucson, among the rocks above the Desert Laboratory, it grows to over a foot in height, with a cluster over six inches long and light dull-green leaves, slightly stiff and thick, with long leaf-stalks, the lobes tipped with a bristle, forming a handsome clump. This grows on dry plains and rocky hillsides, up to seven thousand feet. The picture is from a Grand Canyon plant.
