Flora of North America species comparison

gray, nearly smooth, cross-checked in age into scaly plates and ridges.

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

spreading to ascending, often persistent to trunk base;

twigs pale red-brown, puberulous (rarely glabrous), slightly resinous, aging gray, smooth.

straight to ascending;

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

ovoid, light red-brown, 0.9–1cm, resinous;

lower scales ciliolate along margins.

ovoid-conic, to 2cm, resinous;

scale margins pale fringed.

5 per fascicle, spreading to upcurved and ascending, persisting 5–6 years, 3–7cm × 1–1.5mm, pliant, dark green, abaxial surface with less conspicuous stomatal bands than adaxial surfaces, adaxial surfaces with strong, pale stomatal bands, margins finely serrulate, apex conic-acute to acuminate;

sheath 1–1.5(–2)cm, shed early.

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.

broadly ellipsoid-cylindric, ca. 15mm, pale red or yellow.

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

cones maturing in 2 years, shedding seeds and falling soon thereafter, spreading, symmetric, lance-ovoid before opening, cylindro-ovoid when open, 7–15cm, straw-colored, resinous, sessile to short-stalked, apophyses much thickened, strongly cross-keeled, umbo terminal, depressed.

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.
