78 GENUS PINUS 



49. PINUS OOCARPA 



1838 P. oocAHPA Schiede in Linnaea, xii. 491. 



1842 P. oocARPOiDES Lindley ex Loudon, Encycl. 1118. 



Spring-shoots uninodal, pruinose. Leaves in fascicles of 3, 4 or 5, from 15 to 30 cm. long, erect; 

 resin-ducts mostly septal, sometimes internal, hypoderm biform or multiform. Conelets on very 

 long peduncles, mucronate. Cones from 4 to 10 cm. long, long-pedunculate, broad-ovate to ovate- 

 conic, symmetrical or sometimes oblique, persistent, more or less serotinous; apophysis gray-yellow 

 or greenish yellow of high lustre, flat or variously convex, delicately and radially carinate, the umbo 

 often salient, the prickle usually broken away; seed- wing appreciably thickened at the base of the 

 blade. 



A subtropical species, ranging from Guatemala to the northern border of Sinaloa in northern 

 Mexico; remarkable for the length of the peduncle of the cone and for the prevalence of septal resin- 

 ducts in the leaf.

Spring-shoots often multinodal. Bark-formation late, the branches ashen gray and smooth for 

 several years. Leaves binate, from 6 to 15 cm. long; resin-ducts external, hypoderm uniform. Cone- 

 lets obscurely mucronate near the apex. Cones from 8 to 12 cm. long, ovate-conic, symmetrical or 

 subsymmetrical, persistent, often serotinous; apophyses red with a lighter or deeper brownish shade, 

 lustrous, flat, convex or low-pyramidal, radially carinate, the umbo often ashen gray and unarmed. 



A tree ranging from Portugal to Afghanistan, and from Algeria to Dalmatia and to northern Italy 

 and Southern France. It is a vigorous species in its own home, growing readily in poor soils, but not 

 successful in colder climates. The wood is resinous and valuable for fuel. The turpentine industry, 

 once associated with this species, has gradually been abandoned for the more copious product of 

 P. pinaster. 



It is recognized by its lustrous red cones and by the ashen gray cortex of its branches and upper 

 trunk. Tenore's P. brutia (pyrenaica of some authors) is founded on a difference in the length of 

 the leaf and on an erect cone with a shorter peduncle. To recognize species on such distinctions 

 would not be consistent with the purpose and spirit of this discussion.
