Pinus 1025 



by 6 ft. 8 in. At High Leigh, Hoddesdon, Mr. Clinton-Baker in 1908 measured 

 a tree 66 ft. by 4 ft. 10 in. 



In Scotland the largest known to us is a tree at Murthly (Plate 273), which, 

 when I saw it in 1906, was 85 ft. by 6^ ft. and covered at the top with cones. 

 The next is at Scone, in Perthshire, the seat of the Earl of Mansfield. This, when 

 measured in 1891 for the Conifer Conference, was 71^ ft. high, by 5 ft. 11 in. in girth 

 at about forty years of age ; and when measured by Henry in 1904 had increased to 

 82 ft. by 7 ft. 9 in., and was quite healthy. Another at Keillour, which is probably 

 one of Douglas's original introduction, as it was planted in 1834, was in 1904 

 80 ft. by 6 ft. 9 in. ; and there are many others in Scotland which are from 60 ft. to 

 70 ft. high. One at Monreith, Wigtownshire, planted in 1876, measured in 1908 

 56 ft. by 4 ft. 1 1 in., whilst P. Cembra, planted with it at the same time, is only 

 16 ft. high. Another at Poltalloch, raised from the seed of a tree at Lamb Abbey, 

 measured 50 ft. by 5^ ft. in 1906, and has itself produced fertile seed. 



In Ireland it also grows well. At Hamwood, Co. Meath, the seat of C. R. 

 Hamilton, Esq., there is a splendid tree planted in 1847 which Henry measured in 

 1904 and found to be 76 ft. by 7 ft. At Fota, another measured 69 ft. by 6 ft. 8 in. 

 in 1907. (H. J. E.)

Pinus tenuifolia, Salisbury, Prod. 399 (1796). 



Pinus alba canadensis, Provancher, Fl. Canadienne, ii. 554 (1862). 



A tree, attaining in America at the present time 150 to 175 ft. in height and 10 

 to 15 ft. in girth, but stated to have been much larger formerly. Bark on young 

 stems, thin, smooth, and greenish ; on old trunks i to 3 in. in thickness, and divided 

 by shallow -fissures into broad connected scaly ridges. Buds ovoid, sharp-pointed, 

 ^ in. long, brown, resinous, with some of the scales free at the tips. Young 

 branchlets with short tufts of pubescence below the insertions of the leaf-clusters on 

 the slightly raised pulvini, being glabrous elsewhere.^ 



Leaves in fives, persistent two or three years, spreading, 3 to 4 in. long, very 

 slender, straight, serrulate, whitened with stomatic lines on the two inner surfaces ; 

 resin-canals marginal ; basal sheath | in. long, early deciduous. 



Cones sub-terminal, pendulous on stalks (usually less than i in. long), cylindrical, 

 often curved, pointed at the apex, 4 to 6 in. long, i in. in diameter. Scales i to i|^ 

 in. long, J to f in. wide, usually very convex from side to side ; apophysis smooth, 

 rounded, and thin in upper margin, slightly thickened in the centre, terminating in a 



> Occasionally the pubescence is diffused over the whole surface of the branchlet, but remains densest on the pulvini.
