Papaya, sometimes called papaw ; see Asimina. (Carica Papaya.) 

 Papayaceas. 



As a greenhouse subject, propagated by cuttings of ripe shoots 

 in sandy soil and bottom heat, but branches suitable for cuttings 

 are few. 



As a fruit crop, the papaya is grown from seeds. Seeds started in 

 Florida in January or February should give fruiting plants the 

 following winter. The seeds are sown in light sandy soil about one- 

 half inch deep; care should be taken to prevent damping off; 

 plants may be placed in pots when they have made the third leaves, 

 and from the pots (after another shifting) transferred to permanent 

 quarters. 



The papaya plant may be grafted, special varieties thus being 

 perpetuated. The old plant is cut off and shoots form along the 

 trunk. These are used as cions, being cut to wedge-shape at the 

 lower end and inserted in vigorous seedlings which have been cut 

 back to 8 or 10 inches high. Shoots about the size of a lead pencil 

 are chosen for cions, and the leafage is partly removed. Seeds 

 started in February in Florida, according to Simmonds, will pro- 

 duce stock large enough to graft in March ; the grafted plants are 

 potted, and transferred to the field in late April or in May ; they 

 should bear fruit in November or December. 



Paphiopedilum (Cypripedium of greenhouses). Orchidacece. 



Propagated by seeds sometimes ; usually by division. See 

 Orchids, page 372 ; also Phragmopcdilum, page 392. 



Papyrus (Cyperus Papyrus). Cyperacece. 



Propagated by seeds sown in early autumn or spring, and division, 

 chiefly the latter. 



Paradisea (St. Bruno's Lily). Liliacece. 



Propagated by division, or by seeds sown as soon as ripe. 



Parkinsonia. Leguminosce. 

 Usually raised from seeds. 



Parrotia. HamamelidacecE. 



Multiplied by seeds, layers or by greenwood cuttings under glass. 



Parsley (Petroselinum hortense). UmbellifercB. 



Raised from seeds, which are usually sown outdoors in spring. 

 The roots may be taken up in fall to be forced under glass.
