=Astroloma.= _Epacrideæ._ Propagated by young cuttings placed in sandy soil, under a bell-glass, in a cool house. =Asystasia.= _Acanthaceæ._ Increased by cuttings of young shoots, placed in sand, under a bell-glass, with a strong bottom heat, in spring. =Ataccia.= See Tacca. =Atalantia.= _Rutaceæ._ Propagated by ripened cuttings, which will root freely in sandy soil under a hand-glass, in heat. =Atamasco Lily.= See Amaryllis. =Athamanta.= _Umbelliferæ._ Increased by seeds sown in spring, or by division. =Athanasia.= _Compositæ._ Propagated by means of cuttings taken from half-ripened wood in spring, and placed in sand under a hand-glass. =Atherosperma.= _Monimiaceæ._ Propagated readily by cuttings. =Athlianthus.= See Justicia. =Athrixia.= _Compositæ._ Propagated by cuttings of young wood, under a bell-glass in sandy soil. =Athrotaxis.= _Coniferæ._ Increased by cuttings. =Atragene.= _Ranunculaceæ._ Seeds should be stratified, and sown in early spring, in gentle heat. By layering in autumn; the layers should not be separated for about a year, when they will be vigorous plants. By cuttings, which should be set in light soil and placed under a hand-glass. =Atropa= (Belladonna). _Solanaceæ._ Seeds. =Aubletia.= See Paliurus. =Aubrietia.= _Cruciferæ._ Propagated by seeds, which should be sown in spring. In early autumn carefully transplant to a cool shady border. Also by divisions. Where a stock of old plants exists, layer their long slender branches any time after flowering, and cover with a mixture of sand and leaf soil; they will then root freely and establish themselves in time for spring blooming. Cuttings should be "drawn" or grown in a frame until they are soft, before they are removed. =Aucuba.= _Cornaceæ._ Readily increased by seeds, sown as soon as ripe; or by cuttings, inserted in spring or autumn in sandy soil, with or without a covering. =Audouinia.= _Bruniaceæ._ Propagated by cuttings of half-ripened wood, in sand, under a bell-glass, in gentle heat. =Aulax.= _Proteaceæ._ Increased by ripened cuttings, taken off at a joint, and inserted in pots of sandy soil. These will root well under a hand-glass, in a cool house. =Auricula= (_Primula Auricula_). _Primulaceæ._
