1838 P. oocarpa 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.
