gray, distinctly platy, plates scaly.

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

nearly whorled, spreading-ascending;

twigs slender, pale red-brown, rusty puberulent and slightly glandular (rarely glabrous), aging purple-brown or gray, smooth.

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

ellipsoid or cylindric, rust-colored, 0.4–0.5cm, slightly resinous.

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

scale margins fringed, apex cuspidate.

5 per fascicle, spreading to ascending, persisting 3–4 years, 4–10cm × 0.7–1mm, straight, slightly twisted, pliant, blue-green, abaxial surface without evident stomatal lines, adaxial surfaces with evident stomatal lines, margins finely serrulate, apex broadly to narrowly acute;

sheath 1–1.5cm, 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, 10–15mm, yellow.

cylindric, ca. 20mm, yellow.

cones maturing in 2 years, shedding seeds and falling soon thereafter, clustered, pendent, symmetric, lance-cylindric to ellipsoid-cylindric before opening, broadly lanceoloid to ellipsoid-cylindric when open, 10–25cm, creamy brown to yellowish, without purple or gray tints, resinous, stalks to 2cm;

umbo terminal, depressed.

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;
