So far as we know, however, no case has yet been recorded of a peach or a nectarine producing an almond, or vice versa, although if all have had a common origin such an event might be expected.
The history of the peach almond and nectarine is interesting and important as regards the question of the origin of species and the production and perpetuation of varieties.
The nectarine is a variation from the peach, mainly characterized by the circumstance that, while the skin of the ripe fruit is downy in the peach, it is shining and destitute of hairs in the nectarine.
The treatment in horticulture of the peach and nectarine is the same in every respect.
The Stanwick nectarine, so apt to crack and not to ripen when worked in the ordinary way, is said to be cured of these propensities by being first budded close to the ground, on a very strong-growing Magnum Bonum plum, worked on a Brussels stock, and by then budding the nectarine on the Magnum Bonum about a foot from the ground.
