=Akebia=, Rajania. _Berberideæ._ Seeds. Layers of young or ripe wood. Dormant cuttings in bottom heat, and under glass in summer. =Alangium.= _Alangiaceæ._ Increased by cuttings, which root readily if planted in a pot of sand, with a hand-glass over them, in heat. =Albuca.= _Liliaceæ._ Propagated by seeds and by offsets (bulbels) from the old bulb. =Alcanna.= See Lawsonia. =Alchemilla= (Lady's Mantle). _Rosaceæ._ Propagated by seeds or by divisions of the root. =Aldea.= See Phacelia. =Aletris.= See Tritonia =Aleurites.= _Euphorbiaceæ._ Propagated by ripe cuttings in sand, under a hand-glass. Do not remove leaves. =Alexandrian Laurel.= See Ruscus. =Algaroba Bean.= See Ceratonia. =Alhagi= (Manna Tree). _Leguminosæ._ Increased by seeds sown in a hot-bed; and by cuttings rooted in sand, with a bell-glass over them, in heat. =Alibertia.= _Cinchonaceæ._ Increased by cuttings, which root freely in a mixture of loam and peat, under a hand-glass, in heat. =Alisma=, Actinocarpus (Water Plantain). _Alismaceæ._ Increased by seeds, which should be sown in a pot immersed in water and filled with loam, peat and sand; also by divisions, which root well in a moist loamy soil. =Allamanda.= _Apocynaceæ._ Layers. Root-cuttings will root well at any time of the year in a bottom heat from 70° to 80.° The usual time is, however, in spring, when the old plants are pruned back. Choose the tops of the shoots, retaining two or three joints to each cutting. Place in a compost of sand, and peat or leaf-mould in equal proportions, singly, in pots, and plunge the pots in the propagating bed. =Allium=, including Porrum, Schœnoprasum. _Liliaceæ._ Increased by seeds sown thinly in light soil in early spring. By bulbels, planting them in autumn or spring one to four inches deep. (See Onion.) =Allosorus.= See Ferns. =Almeidea.= _Rutaceæ._ 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.
