dark brown, at maturity deeply furrowed, ridges becoming yellowish, of narrow, elongate, scaly plates.

orange- to red-brown, scaly.

straight to ascending;

twigs stout (1–2cm thick), pale gray-brown, aging darker brown, rough.

descending to spreading-ascending, poorly self-pruning;

twigs slender, orange-red to red-brown, aging gray-brown, rough.

ovoid-conic, to 2cm, resinous;

scale margins pale fringed.

ovoid, red-brown, 0.5–1cm, resinous;

scale margins nearly entire.

3(–5) per fascicle, spreading-ascending, often drooping, forming a brush at twig tips, persisting 2 years, (20–)25–45cm × 2mm, dull green, all surfaces with fine stomatal lines, margins coarsely serrulate, apex conic-subulate;

sheath 3–4cm, base persistent.

2 per fascicle, spreading or ascending, persisting 2–3 years, 2–5cm × 1–1.5(–2)mm, twisted, yellow-green, all surfaces with fine stomatal lines, margins finely serrulate, apex acute to short-subulate;

sheath 0.3–0.6cm, semipersistent.

cylindric, ca. 25mm, yellow to yellow-brown.

cylindric, 10–15mm, yellow to orange-brown.

cones maturing in 2 years and shedding seeds soon thereafter, not persistent, terminal, sometimes curved, often asymmetric, lance-ovoid before opening, ovoid when open, 11–14cm, light dull brown, nearly sessile or short-stalked;

apophyses rhombic, somewhat to quite elongate, strongly raised toward outer cone base, sometimes curved, strongly cross-keeled, narrowed to thick, curved, broadly triangular-based umbo, this often producing outcurved claw.

cones maturing in 2 years, shedding seeds soon thereafter or often long-serotinous and shedding seeds only through age or fire, upcurved, asymmetric, lanceoloid before opening, ovoid when open, 3–5.5cm, tan to light brown or greenish yellow, slick, nearly sessile or short-stalked, most apophyses depressed but increasingly mammillate toward outer cone base;

umbo central, depressed, small, sunken centrally, unarmed or with a small, reflexed apiculus.
