Flora of North America species comparison

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

red-brown, forming square or irregularly rectangular, scaly plates, resin pockets absent.

straight to ascending;

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

spreading-ascending;

twigs moderately slender (to ca. 1cm thick), orangish to yellow-brown, aging darker brown, rough.

ovoid-conic, to 2cm, resinous;

scale margins pale fringed.

lance-cylindric, pale red-brown, 1–1.2(–2)cm, mostly less than 1cm broad, slightly resinous;

scale margins white-fringed, apex acuminate.

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.

2–3 per fascicle, ascending to spreading, persisting 3 years, (10–)12–18(–23)cm × 1–2mm, straight, slightly twisted, pliant, deep yellow-green, all surfaces with narrow stomatal lines, margins finely serrulate, apex acute to abruptly conic-subulate;

sheath 1–2.5cm, base persistent.

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

cylindric, 20–40mm, yellow to yellow-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, not persistent, solitary or in small clusters, nearly terminal, symmetric, lanceoloid before opening, narrowly ovoid when open, 6–12cm, mostly dull yellow-brown, sessile to nearly sessile, scales without dark border on adaxial surface distally;

apophyses dull, slightly thickened, variously raised (more so toward cone base), rhombic, strongly transversely keeled;

umbo central, recurved, stoutly pyramidal, tapering to stout-based, sharp prickle.
