The two prints together illustrate so well the difference between the Crozy Group and the Italian Group that followed. The first print shows the narrower petals of the gladiolus-type French canna and the right shows the so-called, orchid-type 'Italian Job', with petals (really staminodes) that are large, showy, crinkled edges and inclined to be a little floppy (flaccid), showing their descent from the USA species C. flaccida. In addition, the lip (labellum) is larger than the petals.
