Green Gentian (Swertia radiata)
From Frank S. Rose, Mountain Wildflowers of Southern Arizona, pg. 111
After several years, it sends up a stalk that can be as high as eight feet, with many flowers. Many green gentians grow on these mountains, but in any given year few send up a flowering stalk. Not very showy at a distance, its flowers are delightful close up.
