PINUS 



P. AVACAHUITE, 



Ehrcnberg. M EXICAN 



WHITE PINE. 



A tree said to be 100 

 ft. high in nature, and 

 already between 60 and 70 

 ft. high in this country ; 

 in habit very similar to 

 P. excelsa. Young shoots 

 brownish, downy. Leaves 

 in fives, very slender and 

 pointed, falling the third 

 year, 4 to 7 ins. long ; 

 three-sided, two surfaces 

 with three or four white 

 lines of stomata, the other 

 bright green ; margins 

 toothed; leaf-sheaths | in. 

 long, soon falling com- 

 pletely away. Cones 6 to 

 12 ins. sometimes 1 8 ins. 

 long, i to i\ ins. wide 

 before expanding, cylin- 

 drical, with a tapered 

 slightly curved apex- 

 Scales obovate, 2 ins. or 

 more long, the edges thin. 

 Seed with a narrow wing 

 nearly i in. long. The 

 scales at the base of the 

 cone are always curled 

 back almost or quite to 

 the stalk, which they 

 never are in P. excelsa. 



A native of Mexico, 

 where it is widely spread 

 and very variable. Intro- 

 duced by Hartweg for 

 the Royal Horticultural 

 Society in 1840, and after- 

 wards under numerous 

 names by Rgezl. It 

 varies in hardiness, but 

 the shorter - coned form 

 here figured is hardy at 

 Kew. 



Var. VEITCHII, Shaw 

 (P. Veitchii, Roezl], is one 

 of the more tender, 

 larger-coned forms. Only 

 hardy in Cornwall and 

 similar places. 



The cones of this pine 

 are quite distinct from 

 those of P. Armandii, but 



PINUS AYACAHUITB.
