442 A HANDBOOK OF CONIFERS 



long, stout ; resin canals internal ; basal sheath persistent. Cones, 

 conical, 2-4 in. long, persistent, unsymmetrical, or more or less 

 oblique, reflexed, on stout stiff stalks, often produced in abund- 

 ance. Scales with the exposed portion tawny yellow or fulvous 

 brown, the outer scales often much swollen. Seed-wing con- 

 spicuously thickened at the base. 



Confined to the sub-tropical regions of W. Mexico. 



It does not appear to possess any special economic properties. 



Shaw, Genus Pinus, 76 (1914). 



Pinus Pseudo-strobus, Lindley. 

 False Weymouth Pine. 



Pinus Antoineana, Roezl ; P. Escandoniana, Roezl ; P. heteromorpha, 

 Roezl ; P. Hoseriana, Roezl ; P. Montezumae, var. Pseudostrobus ; P. 

 Orizabae, Gordon; P. prasina, Roezl; P. protuberans, Roezl; P. Regeliana, 

 Roezl ; P. taxifolia, Lambert ; P. Tzompoliana, Roezl. False Strobus. 



A tree up to 100 ft. high and 18 ft, in girth. Bark of young 

 trees smooth, becoming rough at the base in older specimens. 

 Branchlets slender, very glaucous. Buds and foliage similar to 

 those of P. Montezumoe. Cones ovate or ovate-conic, sym- 

 metrical or oblique, 3-5| in. long ; scales with the terminal 

 portion variable in shape, flat or protuberant. When the cones 

 fall a few of the lower scales remain on the branches. 



Var. apulcensis, Shaw. 



P. apulcensis, Lindley. 



Cones with the scales much elongated. It grows with the 

 typical form, and is connected with it by intermediates, 



Var. tenuifolia, 8haw. 



P. tenuifolia, Bentham. 



Cones acute or long-ovate, basal scales and stalk persistent 

 on the branch. Hypoderm of the leaves extending from the 

 epiderm to the endoderm, forming partitions across the green 

 tissue. 



The species is distinguished from P. Montezumoe by its smooth 

 bark and glaucous branchlets. 



P, Pseudo-strobus is closely allied to P. Montezumce, and is a 

 native of the sub -tropical and warm-temperate altitudes of 

 Mexico and Central America. It was introduced in 1839. 



Uses similar to those of P. Montezumce. It is only suitable 

 for the warmest and most sheltered parts of the British Isles. 

 Specimens are recorded to exist at Pencarrow and Tregothnan 

 in Cornwall.
