Sometimes the male principle, which loves to exhibit itself in the gay coloring of the petals, seems to influence the leaves also; and they also become colored or variegated; and here we see also a weakened vitality follows. Variegated box, variegated euonyrnus, or any of similar character, never grow so freely, or endure the winter's cold or the extremes of climate like the green-leaved forms. On the other hand, when the balance goes over in the female interest, we see it characterized by greater vigor than before.
