144 PINES 



and often bushy. Bark greyish-brown, fissured and scaly. 

 Branches whorled. 



Jfjf Cones long, cylindroid, and pen- 

 dulous, 150 200mm. long. Needles 

 slender and more or less drooping, 

 bluish or greyish 100 200 mm. long. 



Pinus Strobus, L. Weymouth Pine (Fig. 60). A North 

 American Pine with a tall, straight, terete stem bearing 

 whorls of radiating slender branches, beautifully graduated 

 in a tapering conical or conic-pointed head, though the lower 

 branches may die and remain long on the trunk, as in 

 the Spruce. Bark slate-coloured, remaining smooth for a 

 long time, but fissured and rough on old stems. Leaves 

 10 12 cm. long, slender, in more or less drooping tufts 

 of 5, and bluish-green. Cones long, pendulous and rather 

 Spruce-like, owing to the thin scales. 



Pinus monticola, Don, from North America, and 

 P. excelsa, Wall, the Himalayan Pine are similar, but 

 have longer needles and cones and are less often seen 

 in the tall conical shape in this country. 



It should be noted that the tapering conical -cylindroid 

 form is common and characteristic in young Pines and 

 Firs, but these usually lose this shape long before they 

 are 50 feet high (see p. 67). 



Branches of the pseudo -whorls sweeping 

 forwards, but bearing spray with the leaves 

 isolated not in tufts of 2 5. 

 /~7 Spray horizontally extended, branching, 

 right and left, and fan-like, with its 

 linear leaves also displayed right and 

 left in a comb-like pattern. Cones erect, 

 scales falling from the axis. 



Abies pectinata, DC. Silver Fir (Figs. 15, 61). Tall tree 

 IQO-.-lSO feet high ; the terete stem clothed with regular 

 pseudo-whorls of branches bearing opposite branchlets of
