PINUS MONTEZUM.E. 345 



on the soil on account of the snow pressure. When the snow melts 

 in the following spring and the branches are gradually lightened, they 

 rise up again in consequence of their extraordinary elasticity and resume 

 that position which they occupied in the preceding summer. In the 

 summer, the old leaves on the ends of the Pine branches which wave 

 above the ground more than a yard high, may be frequently seen 

 plastered over with earth and small stones, and any one knowing- 

 nothing of the process above described would not easily understand 

 how these small stones came to be found in these situations. As a 

 matter of fact, the soil on which the branches lie through the winter, 

 moistened by the snow-water, forms the adhesive agent which is so 

 efficient, that stones more than . half-an-inch in diameter are attached 

 by it to the old tufts of leaves." 



The Mountain Pine was in cultivation in Great Britain prior to 

 1779 at which date plants were growing in the garden of Mr. John 

 Blackburn, at Orforcl Hall, near Warrington.* More generally cultivated 

 formerly than at present, it has receded before the more attractive 

 species introduced during the last half-century from western North 

 America and Japan. Clumps of Mountain Pine, both of the shrubby 

 and arborescent forms, may be seen in the Eoyal Gardens at Kew. 



Pinus Montezumae. 



A lofty tree 60 80 or more feet high with a rounded top when 

 old. Bark of trunk (as seen in England) greyish brown, rugged and 

 much fissured into irregular plates. Branches spreading or ascending ; 

 branchlets stout, much roughened with the blackish remains of the 

 sheaths of the fallen leaves. Buds conic, acute, an inch long, covered 

 with lanceolate, imbricated, brown perular scales. Leaves quinate, 

 persistent three four years, triquetral, rigid, mucronate with serrulate 

 margins, 7 10 inches long, bluish green ; basal sheath .whitish, 

 1'25 1'95 inch long, with lacerated margin the first year; much shorter, 

 blackish and corrugated the second year. Staminate flowers in dense 

 clusters, cylindric, 1*25 inch long, fawn-yellow. Cones in clusters of 

 two five, very variable in size even in the same locality, conic or 

 ovoid-conic, 2*5 5 inches long and 1*5 2 inches in diameter near the 

 base ; scales obovate-oblong, closely imbricated, the exposed thickened 

 apex rhomboidal with a transverse ridge and broadly pyramidal central 

 umbo armed with a short deciduous prickle.
