136 UMBRELLA-LIKE TREES 



(125 150 mm.) and reddish-brown; cones 

 about 100 mm. Seeds almost wingless. 



Pinus Pinea, L. Stone Pine (Figs. 56, 58). Attaining 

 60 80 feet, but rarely seen over 30 40 feet. Foliage 

 dense and dark. 



(ii) Bark orange or sienna and cast in large 

 scales in upper parts of stem, but more 

 rugged fissured and greyish below. Needles 

 not over 40 70 mm., and cones pointed, 

 dull grey, 50 70 mm. long ; seeds winged. 



Pinus sylvestris, L. Scots Pine. This only refers to 

 very old trees in favourable situations. Young Pines are 

 conical or cylindroid-conic in form, and clothed from base 

 to apex, or nearly so, with the branches in pseudo-whorls 

 (see p. 75). 



Other Pines in old age may assume the umbellate 

 form above described, of which P. Laricio, considerably 

 like P. sylvestris but with darker and longer foliage and 

 bark nearly black, and P. Pinaster, somewhat resembling 

 P. Pinea, with dull grey bark tinged with reddish- violet, 

 and cones in clusters, are most likely to be met with. 



Old trees of Pinus Strobus, P. Tceda, &c. tend to form 

 a somewhat dome-shaped crown on a longer or shorter 

 stem, nearly approximating to the umbrella-type; and 

 the same is true of some other trees e.g. Quercus Suber. 



(b) Crown not depressed nor umbellate on a tall 

 stem. 



[For (ii) (i) Crown elongated and obviously longer 



Compare than broad. 



(GO) on 



P- 20 fl (a) Crown at least 3 4 times as tall as 



[1 or (8) . 7 7.7.7 



see p. 163.] wide i.e. more or less cylindroid, or 



long oval, pointed or blunt in outline.
