Increased by partly ripened cuttings, which will root in sand, under a hand-glass, in heat.
Almond (Prunus communis). Rosaceæ.
The almond is worked the same as the peach and apricot. Seedling almond stocks are best, but the peach is often used. Apricot stocks are sometimes employed, but they are not to be recommended.
Alnus (Alder Tree). Cupuliferæ.
Propagated usually by seeds, which are gathered in the fall and well dried. Then they are sprinkled lightly on the ground and covered very thinly. Towards the end of the year the seedlings are planted in rows one and one-half feet apart, and six inches from each other, where they may remain for two years, after which they can be placed where they are intended to stand. Planting is best done in October or April. They are also increased, but rarely, by suckers, by cuttings and by grafting.
Alocasia. Aroideæ.
Increased by seeds and divisions.
Commonly propagated by suckers which spring from the base of the plant. Seeds are sometimes employed.
