autumn and by grafting, in early spring, on cratsegus, or the 

 stronger-growing species ; quince and mountain ash are also re- 

 corded as stocks. See Juneberry. 



Ammophila. Gramijieae. 



Propagated by division and can probably be handled easily by 

 root-cuttings. A. arenaria is used for holding sands along sea- 

 shores. 



Amomum. Zingiberacece. 



Propagated by division in the spring. 



Amorpha (Lead-Plant). Lcguminosoe. 



Increased by seeds, usually. Greenwood cuttings strike readily 

 early in the season under glass. Hardwood cuttings may be planted 

 in the open, in a protected place, in autumn and allowed to remain 

 for a year. Suckers and layers may also be used. 



Amorphophallus. Araceae. 



Propagated by offsets, or cormels, and by seeds, which, however, 

 are usually sparingly produced in cultivation. Place offsets in pots 

 in mixture of loam, leaf -mold and sand, in temperature of 65 to 

 70. Some of the large kinds do not increase rapidly, as offsets 

 may not be formed. See Araccce, page 239. 



Ampelopsis. Vitacece. 



Increased by seeds. Layers or cuttings made in spring from the 

 young soft wood root freely in gentle heat. All species may be 

 propagated by hardwood cuttings taken in September and pricked 

 out under hand-lights or in a frame. Softwood cuttings may also 

 be taken in summer under glass. For Virginia creeper, see Parthe- 

 nocissus. 



Amygdalus : Prunus. 



Anacardium (Cashew). Anacardiaceoe. 



Mature-wood cuttings, with leaves on, root in sand under 

 glass, in heat. Also increased by means of seeds, when obtain- 

 able. 



Anagallis (Pimpernel). Primulaceoe. 



The annuals are propagated by seeds sown in the open in spring ; 

 the perennials, by cuttings from young shoots, or by division. 

 The cuttings should be handled under glass.
