Some of my pale yellow samples of Yellow Bellflower are less tapered than this (photo). Nonetheless, all sit on tiny bases (or, if you prefer, crowns ) around partially open calyxes. Some have faint streaks of a pink orange blush, and all are ribbed and decorated with dark lenticel dots, large and distinct above, tiny and close together below. You can feel them with your fingertips, rough projections from the peel.
