In biological terms, these are the characteristic behaviors of sexually dimorphous territorial animals.
Our species is sexually dimorphous — the symbolism of "male" and "female" as sexually generative is rather primordially a part of the idea of marriage, don't you think?
In 1841 he made the discovery that dimorphous bodies have different fusing points, according as they are in the crystallized or amorphous condition.
Leaves and shoots dimorphous, primary leaves on long shoots, secondary leaves on dwarf shoots.
But they owe this quality entirely to their dimorphous character.
Here I might refer to the observations concerning the invisible dimorphous state of the flowers of the normal toad-flax.
Manifestly the dimorphous cases are to be considered as the younger ones, partly because they are obvious exceptions to the common rule, and  partly because the division of labor is indicative of a higher degree of evolution.
Granting these conclusions, monstrosities on the one side, and dimorphous wild species on the other, constitute the most striking examples of the inheritance of latent characters.
On this conclusion it becomes at once clear, why natural dimorphism is, as a rule, a very useful quality, while the cultivated dimorphous varieties  strike us as something unnatural.
But they are always relatively rare, and any lot of plants conveys the idea of a dimorphous race, the small twisted stems contrasting strongly with the tall straight ones.
