Flora of North America species comparison

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

gray, distinctly platy, plates scaly.

straight to ascending;

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

nearly whorled, spreading-ascending;

twigs slender, pale red-brown, rusty puberulent and slightly glandular (rarely glabrous), aging purple-brown or gray, smooth.

ovoid-conic, to 2cm, resinous;

scale margins pale fringed.

ellipsoid or cylindric, rust-colored, 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.

5 per fascicle, spreading to ascending, persisting 3–4 years, 4–10cm × 0.7–1mm, straight, slightly twisted, pliant, blue-green, abaxial surface without evident stomatal lines, adaxial surfaces with evident stomatal lines, margins finely serrulate, apex broadly to narrowly acute;

sheath 1–1.5cm, shed early.

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

ellipsoid, 10–15mm, 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, clustered, pendent, symmetric, lance-cylindric to ellipsoid-cylindric before opening, broadly lanceoloid to ellipsoid-cylindric when open, 10–25cm, creamy brown to yellowish, without purple or gray tints, resinous, stalks to 2cm;

umbo terminal, depressed.
