PlNUS TEOCOTE VAR. MACROCARPA. N. VAR. 



Pinus leiophylla Bentham, PI. Hartw. 58 (in part), (1842). 



Cones considerably larger than those of the typical form ; leaves in fascicles of 3, 4 or 5.

The variety macrocarpa is illustrated by the cone, of Lambert's plate of P. teocote, which, as jstated by Schlech- 

 tendal in Linnaea xii, 488, is larger than the typical teocote cone. Most of the specimens labelled Hart- 

 weg 441 (Pinus leiophylla, foliis longioribus, Bentham, PL Hartw. 58) belong here as well as a specimen at Kew 

 labelled Pinus intermedia Roezl. This variety may easily be confused with some forms of the variable P. Law- 

 soni. between which and P. teocote it seems to be intermediate; so far as I know however, this variety does not 

 grow in subtropical regions and its leaf anatomy corresponds with that of P. teocote. 



The variations in the length and thickness of the leaf of P. teocote are illustrated by figs. 1 to 4 on Plate X. 

 There is also some variation in the length of the cone, and occasionally a cone is found with protuberant apo- 

 physes (Plate IX, fig. 2). 



The typical form of the species is usually very easily recognized by its small cone and is like no other Mexican 

 Pine. 



"Ocote," from which the name of this species is derived, is apparently used by the Mexicans as the common 

 name of all Pitch Pines and of their wood. Small bundles of kindling-wood are offered for sale in the markets of 

 Mexican cities under the name "ocote." This kindling-wood is obtained by slashing the standing tree and, after 

 allowing time for the resin to accumulate over the wound, by repeating the process at intervals. The chips are 

 tied into small bundles and are retailed in the markets for one centavo each. Trees badly disfigured by the ocote 

 gatherers are frequently seen.
