These large showy flowers on long peduncles give us a better chance to watch the family characters than the tiny flowers of screwstems (Bartonia). The corolla lobes in most gentians are convolute (rolled longitudinally) in the bud. Typically gentian flowers are either four or five-merous; fringed gentian flower is four-merous: there are four lobes both in calyx and corolla. Photo taken in western Massachusetts.
