THE NURSERY-LIST 391 



Phsedranthus. Bignoniacece. 



Propagation as for bignonia, which see. 



Phaius. Orchidaceoe. 



Increased by division of the dormant pseudobulbs. See Orchids. 



Phalaenopsis. Orchidacece. 



The kinds of phalsenopsis are very slow and difficult to propagate. 

 In most of the species it can only be done when a lateral offshoot 

 is made from the main stem. Some species, such as P. Lueddeman- 

 niana, and more rarely P. amabilis, P. Stuartiana&nd P. Schilleriana, 

 develop plantlets on the old flower-scapes. By pegging these down 

 on a basket of moss, they may be established and afterwards sepa- 

 rated. P. Stuartiana has been known to produce plants on the 

 roots. Other examples of root-proliferation are recorded in Sac- 

 colabium micranthum and a species of cyrtopodium. See under 

 Orchids, page 372. 



Phalaris. Gramineoe. 



Handled by seeds, but the sports or varieties by division. The 

 perennial P. arundinacea may be divided when transplanting. See 

 Crosses, page 328. 



Phaseolus (Bean. Kidney, Pole, String, Lima, French Bean). 



LeguminoscB. 



The ornamental greenhouse kinds are grown from seeds planted 

 in light soil in a warm propaga ting-house. For the edible and 

 culinary kinds, see Bean. 



Phellodendron (Cork Tree). Rutacece. 



Increased by seeds, layers, root-cuttings dug up in fall and stored 

 during winter in moist sand or sphagnum, and by cuttings taken 

 from the tree in July with a heel of older wood. Seeds usually are 

 employed, when produced. 

 Philadelphus (Mock Orange. Syringa, erroneously). Saxifragaceae. 



Propagated by seeds, layers, suckers and cuttings. Cuttings of 

 mature wood are generally employed. Some well-marked varieties, 

 like var. nanus of P. coronarius, are grown from cuttings of soft 

 wood in summer in frames. 



Phillyrea (Jasmine Box. Mock Privet). Oleaceae. 



May be propagated by seeds sown soon after maturity, cuttings 

 of half-ripened wood under glass in summer, layers, and by grafting 

 on the privet (as on Ligustrum ovalifolium).
