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.
