red-brown, irregularly furrowed or cross-checked, scaly.

red-brown, deeply and irregularly furrowed, with long, irregularly rectangular, flat, scaly ridges, resin pockets absent.

spreading and ascending, persistent to near trunk base;

twigs stout, orange-brown, aging brown to gray, sometimes sparsely puberulent.

arching-spreading to ascending, poorly self-pruning; 2-year-old branchlets stout (mostly over 5mm thick), orange-brown, aging darker brown, rough.

ellipsoid, light red-brown, 0.5–0.7cm, resinous;

scale margins fringed.

ovoid to ovoid-cylindric, red-brown, ca. 1–1.5cm, resinous;

scale margins fringed, apex cuspidate.

1(–2) per fascicle, ascending, persisting 4–6(–10) years, 2–6cm × 1.3–2(–2.5)mm, curved, terete (though often 2-grooved), gray-green, all surfaces with stomatal lines, margins entire, apex subulate;

sheath 0.5–1cm, scales soon recurved, forming rosette, shed early.

3(–5) per fascicle, spreading to ascending, persisting 2–3 years, 5–10(–15)cm × 1–1.5(–2)mm, straight, twisted, deep to pale yellow-green, all surfaces with fine stomatal lines, margins serrulate, apex abruptly subulate-acuminate;

sheath 0.9–1.2cm, base persistent.

ellipsoid, ca. 10mm, yellow.

cylindric, ca. 20mm, yellow.

cones maturing in 2 years, shedding seeds and falling soon thereafter, spreading, symmetric, ovoid before opening, broadly depressed-ovoid to nearly globose when open, 4–6(–8)cm, pale yellow-brown, nearly sessile;

apophyses thickened, slightly raised;

umbo subcentral, raised or depressed, nearly truncate, apiculate.

cones maturing in 2 years, shedding seeds soon thereafter or variously serotinous and long-persistent, often clustered, symmetric, conic to ovoid before opening, broadly ovoid with flat or slightly convex base when open, 3–9cm, creamy brown to light red-brown, sessile to short-stalked, base truncate, scales firm, with dark red-brown border on adaxial surface distally;
