Flora of North America species comparison

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

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

straight to ascending;

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

spreading and ascending, persistent to near trunk base;

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

ovoid-conic, to 2cm, resinous;

scale margins pale fringed.

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

scale margins fringed.

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.

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.

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

ellipsoid, ca. 10mm, yellow.

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 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.
