Propagated by imported seeds, and by cuttings in bottom heat. =Acrocomia.= _Palmæ._ Propagated by suckers. =Acronychia.= _Rutaceæ._ Propagated in July by cuttings inserted in sand, under a bell-glass. =Acrophyllum.= _Cunoniaceæ._ Increased by cuttings of the half-ripened shoots which strike freely in a soil of sand and peat; cover with a hand-glass, and place in a cool house. The roots should be kept moist. =Acrostichum.= See Ferns. =Acrotriche.= _Epacridaceæ._ Propagated by cuttings made of young shoots, pricked in sand, covered with a bell-glass, and placed in a cool house; afterwards treated like Epacris. =Actæa= (Baneberry). _Ranunculaceæ._ Propagated by seed and by division of root during spring. =Actinella=, Picradenin. _Compositæ._ Propagated in spring by divisions. =Actinidia.= _Ternstrœmiaceæ._ Propagated by seeds, layers or cuttings. The cuttings should be put in sandy soil, in autumn, under a hand-light. =Actinocarpus.= _Alismaceæ._ Propagated by seeds and divisions during spring. =Actinomeris=, Pterophyton. _Compositæ._ Increased in spring, by seeds and division. Use a warm border, with or without hand-lights, or a cold-frame. =Actinophyllum.= See Sciadophyllum. =Actinotus.= _Umbelliferæ._ Increased by seeds sown on a hotbed in spring, and in May the seedlings may be transplanted to the open border in a warm situation, where they will flower and seed freely. Divisions of the roots grow readily. =Acyntha.= See Sanseviera. =Ada.= _Orchideæ._ Propagated by divisions as soon as the plant commences growth. (See under Orchids.) =Adamia.= _Saxifrageæ._ Increased by seeds; by cuttings, which will root readily in a compost of loam, peat and sand, under a hand-glass. =Adamsia.= See Puschkinia. =Adam's Needle.= See Yucca. =Adenandra.= _Rutaceæ._ Increased by cuttings made from the young tops, before they begin to throw out their buds, planted in a pot of sand, with a bell-glass or frame placed over them. =Adenanthera.= _Leguminosæ._ Increased by cuttings taken off with a heel and planted in a pot of sand in heat, placing a bell-glass over them. =Adenanthos.= _Proteaceæ._ Propagated by cuttings, in spring, placed in sandy soil, under a bell-glass, with gentle bottom heat. =Adenilenia.= See Neillia. =Adenium.= _Apocynaceæ._ Increased by half-ripened cuttings, which strike root well in sand, under a hand-glass. =Adenocalymna.= _Bignoniaceæ._ Propagated by cuttings, which will root in sand, under a bell-glass, with bottom heat. =Adenocarpus.= _Leguminosæ._ Seeds may be sown in March, the hardy species out-doors, and the others in a cold house. Young cuttings root freely in sand, covered with a hand-glass. =Adenophora.= _Campanulaceæ._
