Flora of North America species comparison

red-brown, shallowly and irregularly furrowed, ridges scaly, rounded.

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

persistent to near trunk base;

twigs pale red-brown to tan, rarely glaucous, aging gray-brown to gray, glabrous to papillose-puberulent.

straight to ascending;

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

ovoid to ellipsoid, red-brown, 0.5–1cm, resinous.

ovoid-conic, to 2cm, resinous;

scale margins pale fringed.

(1–)2(–3) per fascicle, upcurved, persisting 4–6 years, 2–4cm × (0.9–)1–1.5mm, connivent, 2-sided (1-leaved fascicles with leaves 2-grooved, 3-leaved fascicles with leaves 3-sided), blue-green, all surfaces marked with pale stomatal bands, particularly the adaxial, margins entire or finely serrulate, apex narrowly acute to subulate;

sheath 0.5–0.7cm, scales soon recurved, forming rosette, 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.

ellipsoid, ca. 7mm, yellowish to red-brown.

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

cones maturing in 2 years, shedding seeds and falling soon thereafter, spreading, symmetric, ovoid before opening, depressed-ovoid to nearly globose when open, ca. (3.5–)4(–5)cm, pale yellow- to pale red-brown, resinous, nearly sessile to short-stalked;

apophyses thickened, raised, angulate;

umbo subcentral, slightly raised or depressed, truncate or umbilicate.

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.
