P. STROBUS ( White Pine : Weymotith Pine}. 

 One of the noblest forest trees of the northern 

 world, sometimes reaching a height of over 170 

 ft. , with a girth of trunk of 30 ft. , though often 

 found much smaller. Owing to the cutting of 

 the woods in Canada and Northern America, 

 it is seldom seen in its native dignity in the 

 settled parts. It forms dense forests in New- 

 foundland and Canada, and westwards and

southwards along the mountains. Certain 

 varieties are catalogued, but they are of little 

 use beside the parent tree. 



P. SYLVESTRIS (Scotch Pine). Our native 

 Pine and, in its old state, one of the most beau- 

 tiful and useful we can ever have. It is of 

 very wide distribution in Northern, Arctic, 

 and mountain regions, and also on the moun- 

 tains of Italy and Greece. The Russian 



variety is considered a more erect and stronger 

 grower. A great number of varieties is men- 

 tioned in books and catalogues, and some 

 hybrids, compact and dwarf varieties, including

variegated ones, none of any consequence com- 

 pared to the wild tree. This Pine sows itself 

 in rough heaths and sandy ground, and thrives 

 there, if allowed to do so under these con- 

 ditions. 



PIPTANTHUS (Ncpaul Laburnum}.- - 

 P. nepalensis is a Pea-flowered shrub, 

 hardy enough for walls, which it covers 

 with large deep green leaves similar in 

 shape to those of the common Laburnum, 

 and in southern and warm localities with- 

 stands our winters without even this 

 protection. But it is only to be recom- 

 mended for walls, and is not the most 

 desirable of plants even for them. It 

 has evergreen foliage, and in early summer 

 long dense clusters of large bright yellow 

 flowers similar to those of the Laburnum, 

 but larger. It succeeds best in light soils, 

 and in the west and south thrives away 

 from walls and among shrubs as at 

 Madresfield. Himalayan Region. 



PITTOSPORUM. Evergreen shrubs, 

 natives of New Zealand, Australia and 

 China, few of them in cultivation and 

 those usually only seen in southern gar- 

 dens or those in sheltered places near the 

 sea where they form evergreen bushes 

 and trees of some beauty and distinctness 

 of form. P. tobara is a good white 

 flowering shrub in some southern gardens 

 and is among the plants worth growing 

 in tubs or vases for placing out in the 

 summer. P. undulatiun is a graceful
