THE NURSERY-BOOK. 



Palicourea. Rubmcece. 



Cuttings, made in spring under glass. 

 Paliurus, Aubletia (Christ's Thorn). Rhamnece. 



May be increased by seeds, by layers or by cuttings of the 

 roots. 



Palma-Christi. See Ricinus. 



Palms. Palmce. 



Palms are mostly grown from imported seeds. These 

 should always be sown in a brisk bottom heat, in a mixture 

 of coarse loam and sand. A hot-bed, established upon the 

 greenhouse bench, is an excellent place in which to start 

 palm seeds. Some species are increased by suckers, which 

 arise from the crown or roots. For more explicit directions, 

 see the various genera. 



Pampas Grass. See Gynerium. 



Panax (Ginseng). Araliacece. 



Cuttings of stems and roots. Stems of old plants may be 

 cut into pieces an inch or two long and inserted in sand in 

 heat. Or young plants can be obtained by cutting down the 

 tops of strong plants and then separating the suckers which 

 arise. 



Pancratium and Hymenocallis. Amaryllidece, 



Seeds, sown in pans in heat, are sometimes employed. 

 Commonly increased by offsets, which usually form freely 



Pandanus (Screw Pine). Pandanece. 



Seeds and suckers, as in palms. Also by cuttings of the 

 young growth in heat. The "seeds" are really fruits, and 

 if in good condition several plants, one to ten, are obtainable 

 from each ; they should be separated when well furnished 

 with roots. 



Pansy. See Viola. 



Papaver (Poppy). Papaveracece. 



Seeds usually sown out-doors and divisions. P. onen- 



talis and allied species are easily propagated by root cuttings 



in sandy soil under glass in autumn. 



Papaw-tiee. See Carica ; also Asimina. 

 Papyrus. Cyperacece. 



Propagation is effected by seeds and by divisions, chiefly 

 the latter.
