Extreme Development of Another Type
This calendula, like the preceding one, represents something like the limits of variation in a given direction; but in this case the variation is of a different type from the other. Here the rays are long and graceful, and the flower is less compact in form, though not lacking in distinction. The two flowers, like the others shown, have been selected for different qualities from among the progeny of the same remote ancestors.
