vicinism

For this purpose I propose the word vicinism, derived from the Latin vicinus or neighbor, as indicating the sporting of a variety under the influence of others in its vicinity.

This impurity we have called vicinism, and in a previous lecture have shown its effects upon the horticultural races on one hand, and on the other, on the scientific value that can be ascribed to the experience of the breeder.

De Vries distinguishes this kind of atavism as vicinism (Lat. vicinus, neighbour), and says that it

And this mode of cultivation being in almost universal use in the larger nurseries, [208] we may, by this discussion, arrive at a more scientific estimation of the phenomena of vicinism, hitherto described.

In the light of this experience, Metzger's observation becomes a typical instance of vicinism.

For this reason, we will furthermore designate all variations under the influence of neighbors with the new and special term "vicinism."

Keeping this rule in view, it will be easy to calculate what may be expected from spontaneous crosses for a wide range of occurrences, and thus to find an explanation of innumerable cases of apparent variability and reversion in the principle of vicinism.

In concluding I will point out another danger which in the principle of vicinism may be avoided.

But in former times, when this principle was still unknown and not even guessed at, it is evident that many mistakes must have been made, and that many an instance, which until now has been considered reliable proof of a so-called single variation, is in fact only a case of vicinism.

It appeared suddenly, yielded a good crop of seed and was constant from the outset, without any sign of vicinism or impurity.
