Flora of North America species comparison

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

red-brown, irregularly furrowed and cross-checked to irregularly rectangular, plates scaly.

straight to ascending;

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

spreading to ascending, persistent to trunk base;

twigs slender, pale orange-brown, puberulent-glandular, aging brown to gray-brown.

ovoid-conic, to 2cm, resinous;

scale margins pale fringed.

ovoid, light red-brown, ca. 0.4–0.5cm, slightly resinous.

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.

(3–)4(–5) per fascicle, persisting 3–4 years, (2–)3–6cm × (1–)1.2–1.7mm, curved, connivent, stiff, green to blue-green, margins entire to minutely scaly-denticulate, finely serrulate, apex subulate, adaxial surfaces mostly strongly whitened with stomatal bands, abaxial surface not so but 2 subepidermal resin bands evident;

sheath 0.5–0.6cm, scales soon recurved, forming rosette, shed early.

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

ovoid, ca. 10mm, yellowish.

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 ovoid to depressed-globose when open, (3–)4–8(–10)cm, pale yellow-brown, sessile to short-stalked, apophyses thickened, strongly raised, diamond-shaped, transversely keeled, umbo subcentral, low-pyramidal or sunken, blunt.
