Flora of North America species comparison

red-brown, shallowly to deeply fissured with thick, scaly, irregular, blocky ridges.

gray, distinctly platy, plates scaly.

contorted, pendent;

twigs pale red-brown, aging gray to yellow-gray, puberulent, young branches resembling long bottlebrushes because of persistent leaves.

nearly whorled, spreading-ascending;

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

ovoid-acuminate, pale red-brown, ca. 1cm, resinous.

ellipsoid or cylindric, rust-colored, 0.4–0.5cm, slightly resinous.

mostly 5 per fascicle, upcurved, persisting 10–30 years, 1.5–3.5cm × 0.8–1.2mm, mostly connivent, deep yellow-green, with few resin splotches but often scurfy with pale scales, abaxial surface without median groove but with 2 subepidermal but evident resin bands, adaxial surfaces conspicuously whitened with stomates, margins entire or remotely and finely serrulate distally, apex bluntly acute to short-acuminate;

sheath ca. 1cm, soon forming rosette, shed early.

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.

cylindro-ellipsoid, 7–10mm, purple-red.

ellipsoid, 10–15mm, yellow.

cones maturing in 2 years, shedding seeds and falling soon thereafter, spreading, symmetric, lance-cylindric with rounded base before opening, lance-cylindric to narrowly ovoid when open, 6–9.5cm, purple, aging red-brown, nearly sessile;

apophyses much thickened, sharply keeled;

umbo central, raised on low buttress, truncate to umbilicate, abruptly narrowed to slender but stiff, variable prickle 1–6mm, resin exudate pale.

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;
