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. Conelets 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.
