PlCEA PUNOENS GLAUCA (seep. 198). 



PICRORHIZA. 



The only species, Kurrooa, is a hardy perennial 

 herb (ord. Scrophularinese) of no great value, as it 

 rarely blooms. 



PICTETIA. 



Stove evergreen shrubs (ord. Leguminosse), 

 handsome, but rarely grown. Propagation, by 

 cuttings, in sand, under a bell-glass, in brisk 

 heat. Soil, loam and sandy peat in equal parts. 



when planted in masses than as solitary specimens. 

 A bed or two filled with them may find 'a place 

 upon the lawn or in the American garden, and the 

 plants form admirable companions for Liliums, 

 which may be planted between. Propagation, by 

 layers in autumn, and by seeds sown as soon as 

 they are ripe, preferably in cool frames. Soil, 

 sandy peat. A well-drained situation is impera- 

 tive. In heavy, cold, tenacious soils, which are 

 waterlogged in winter, the plants do not 

 thrive.
