habit, and in a young state rather slow in growth, but 

 when properly established it grows fairly rapidly. P. contorta 

 (P. , Bolanderi, P. Boursieri) (Fig. 320) is a medium-sized 

 handsome tree from California, with a straight, stout trunk, short 

 branches, and deep green leaves. It thrives well in damp soils, 

 and owing to the short spread of its branches it can be recom- 

 mended for gardens of restricted areas. P. Coulteri (P. macro- 

 carpa) succeeds admirably on poor soils, and is amongst the 

 most ornamental of Pines. It is a Californian species, distinct, 

 and free in growth, with long, strong, horizontal branches and 

 long, narrow, glaucous 

 leaves. A radius of about 

 30ft. should be allowed for 

 this tree to reveal its true 

 character. 



P. excelsa (Bhotan Pine) 

 (Fig. 321), an elegant 

 Himalayan species, is quite 

 hardy, and has an erect 

 trunk with long, spreading 

 branches, feathered to the 

 ground. Its pendulous 

 leaves are long and bluish- 

 green in colour. It requires 

 plenty of head-room, and 

 succeeds best in light soil. 

 Shelter from east wind is 

 important. P. halepensis 

 (P. abchasica, P. maritima, 

 P. Pithyusd), the Jeru- 

 salem Pine, prefers shelter 

 from piercing winds. It is 

 a medium-sized tree of 

 pyramidal outline, with 

 slender branches and long 

 pale green leaves. For 

 planting in the warmer 

 counties, especially in mari- 

 time districts, this species is well adapted. P. insignis 

 (P. radiatd), the Monterey Pine, is a particularly handsome 

 Californian species, fairly hardy, and free in growth, having 

 numerous stout branches, closely packed with glossy green 

 leaves. It is a splendid lawn tree, and like the last-named 

 should be shielded from cold winds. It is spring tender, 

 for which reason it should be planted in a cold soil, and in 

 a situation not 'favourable to early growth. A capital Pine 

 for the sea coast. P. Jeffreyi, also a Californian species, forms 

 a tall, handsome tree, with a rather spreading head, bearing
