more rapidly. The timber is exported largely from ports on the 

 Gulf of Mexico. For further particulars see under P. palustris. 

 The Loblolly pine thrives in a variety of soils, but is better 

 adapted for wet positions than most pines. It reproduces itself 

 rapidly and is often the first tree to take possession of prairie 

 swamps as soon as small hillocks rise above the general moisture. 

 Farm land that has been allowed to go out of cultivation is soon 

 covered by this tree, whilst its regular seeding and adaptable 

 habits enable it to encroach on land occupied by other species 

 and gradually oust them. It seems likely that in a generation 

 or two it will cover a much larger area than at present and will 

 possibly become the most important soft wood of the S.E. States 

 of N. America. From United States reports it appears that very 

 useful timber can be grown on a 40-50 years' rotation, and it is 

 probable that no rotation need be carried further than 70 years. 

 The climatic conditions obtaining in the British Isles are quite 

 vnisuitable for this species, and as it gives very poor results as an 

 ornamental tree it would be useless to consider it from a forestry 

 standpoint.

Pinus Bessereriana, Roezl ; P. microcarpa, Roezl ; P. Muelleriana, 

 Roezl ; P. Vilmoriniana, Roezl. Tecote. 



A tree 90 ft. high with fissured scaly bark. Young shoots 

 glabrous, glaucous. Winter buds cylinclric-conic, about f in. 

 long, with resinous, fringed scales. Leaves usually in threes but 

 sometimes in fives, lasting 3 years, spreading, rigid, 4-8 in. long, 

 margins finely toothed, apex a sharp, horny point ; stomatic lines 

 on each surface ; resin canals median ; basal sheath about 1 in. 

 long, persistent. Cones sub-terminal or rarely lateral, solitary 

 or in pairs, spreading or reflexed, ovate-oblong, about 2^ in. 

 long, dull brown ; scales numerous, f in. long, ^ in. wide, the 

 terminal portion fiat or swollen, transversely ridged. Seed small 

 with a narrow wing. 



P. Teocote may generally be distinguished by its small cone — 

 although a large-coned form, var. macrocarpa, Shaw, occurs. 

 From P. leiophylla it is distinguished by its biennial cone. 



A native of the Sierras of Mexico, where it is associated with 

 other warm temperate species including P. patula, and P. 

 leiophylla. 



P. Teocote has been known in cultivation in the mildest parts 

 of the British Isles since 1826 when a single tree existed in
