1 1 04 The Trees of Great Britain and Ireland 



The leaves are longer than is usually the case in var. Brutia, measuring about 7 in. 

 in length, which is probably due to the rich volcanic soil in which the tree is growing. 

 Henry sees no reason for supposing that the tree is a hybrid, though from its vigour 

 M. Cavara thinks that it differs from the wild trees in Calabria, which are ascribed 

 to var. Brutia. 



There is a fine tree, under the name P. pyrenatca, in the grounds of the Villa 

 Thur^t, Antibes, which was 70 ft. by 6 ft. 2 in. when I saw it in 19 10, and bore 

 cones larger than those of typical P. halepensis. 



The timber^ is considered in France inferior to that of P. Pinaster, and is 

 characterised by large resin -canals, which often cause infiltrations of resin in the 

 wood, rendering it hard, heavy, and difficult to saw. It is little used, except for 

 making packing-cases, though sometimes it is suitable for telegraph poles and 

 sleepers. Tapping for resin, formerly practised in Provence, is now little in vogue ; 

 but in 1906, an experiment was made in the forest of Slisser, in western Algeria, 

 when about a million trees were tapped. The resin produces a turpentine of good 

 quality. The bark contains a considerable amount of tannin, and in Provence is 

 occasionally ground into powder, which is used for dyeing fishing nets, and for mix- 

 ing with the tanning material obtained from the bark of Quercus cocci/era.

A tree, usually 40 to 50, occasionally 90 ft. high, and 6 to 10 ft. in girth. Bark 

 reddish brown, Assuring into long narrow rounded scaly ridges, becoming very thick,'' 

 4 to 6 in., towards the base of old trunks. Young branchlets glabrous, stout, reddish 

 brown, with projecting pulvini, separated by linear grooves. Buds conic or cylin- 

 drical, pointed, | to i in. long, encrusted with white resin. Scale-leaves persistent at 

 the base of the leaf-clusters. 



Leaves ° in pairs, persistent for three or four years, spreading, crowded on the 

 branchlets, 4 to 6 in. long, yellowish green, rigid, slightly curved and twisted, 

 serrulate, marked with numerous stomatic lines on both surfaces, ending in a short 

 callous tip ; resin-canals median ; basal sheath \ in. long. 



Cones, both sub-terminal and lateral, in clusters of 3 to 7, deflexed, sessile, 

 asymmetrical, oblique at the base, ovoid, about 3 in. long, shining brown, very 

 prickly : scales transversely keeled ; on the inner side of the cone with flattened 

 apophyses and slender prickles; on the outer side of the cone with elevated
