PINUS 185 



P. MONTE/A* M.E, Lambert. MONTEZUMA PINE. 



A tree up to 70 ft. high, with very thick, reddish brown young branchlets 

 that are rough with fringed scale-leaves, the scaly bases of the fallen leaf- 

 bundles and the prominences on which they were seated ; not downy. 

 Winter buds I in. long, -J- in. thick, clothed with long, fringed scales. 

 Leaves in fives, very crowded, persisting three years ; from 7 to 12 ins. 

 long, blue-green, minutely toothed on the margin ; leaf-sheaths up to 

 2 ins. long, persistent. Cones very variable, usually from 4 to 8 ins. long, 



2 to 3? ins. wide at the base, tapering upwards. 



Native of Mexico, where it is very widely spread and abundant ; introduced 

 by Hartweg in 1839. In some respects, especially in size of leaf (known 

 sometimes to be 18 ins. long), this is the most remarkable of all pines, 

 but it is only hardy in Cornwall, the south-west of Ireland, and such- 

 like places. There are good specimens at Fota in Ireland, Bicton in 

 Devon, Pencarrow, Menabilly, Tregothnan, and other places in Cornwall. 

 It belongs to the small group of five-leaved pines, with persistent leaf- 

 sheaths, the hardiest of which is P. Hartwegi. The pines known in the 

 gardens of the south-west as P. RUSSELLIANA, DEVONIANA, and LINDLEYANA 

 are forms of P. Montezumae. 



Nearly allied to it is P. PSEUDO-STROBUS, Lindley, which is, however, 

 easily distinguished by its very glaucous, more slender shoots. It is as 

 tender as P. Montezumae, and appears only to exist in this country at 

 Pencarrow and Tregothnan. The Pencarrow specimen has leaves 10 ins. 

 long, more slender than in P. Montezumae, but -in other respects similar. 

 Native of Mexico ; introduced in 1839. 



P. MONTICOLA, Don. WESTERN WHITE TINE. 



A tree up to 125 ft. high, with a trunk 4 ft. or more in diameter; young 

 shoots downy ; winter bu4s ovoid, with flattened scales. Leaves in fives, 



3 to 4^ ins. long, rough at the margins (minutely toothed under the lens), 

 glaucous green, with several lines of stomata on the inner sides ; leaf-sheath 

 about f in. long, soon falling. Cones 5 to 8 ins. long, \\ ins. wide before 

 expanding, cylindrical, tapered, and curved towards the end ; scales thin, 

 smooth, rounded at the apex, terminated by a dark resinous scar (umbo). 



Native of Western N. America from British Columbia and Vancouver 

 Island to California ; introduced by Douglas in 1831. Although not so 

 well known in this country as its eastern ally P. Strobus, it is a handsome 

 tree for gardens, assuming a shapely, slender, pyramidal shape. It is liable 

 to be confused with P. Strobus, but the short down all over the shoot 

 usually distinguishes it. Its leaves also are stiffer and stouter. It yields 

 a useful timber in its native home, but in Europe is planted for ornament 

 only. A tree at Murthly and another at Scone in Perthshire are both 

 over 80 ft. high. 



P. MURICATA, Don. BISHOP'S PINE. 



(P. Edgariana, Harlweg.) 



A tree 50 to 90 ft. high, with a rough brown bark, often flat-topped and 

 with wide-speading branches ; young shoots densely leafy, smooth, brown ; 

 terminal buds cylindrical, pointed, ^ to I in. long, coated with resin. 

 Leaves in pairs, falling the third or fourth year, rigid, 3 to 5 (sometimes 7) 

 ins. long, semi-terete, dark green ; leaf-sheath persistent, ^ to f in. long. 

 Cones obliquely egg-shaped, 2^ to 3^ ins. long, the boss on the scales 

 terminated by a stiff, slightly hooked spine. (See plate, Vol. i., p. 104.)
