Flora of North America species comparison

gray, distinctly platy, plates scaly.

pale gray, from distance appearing whitish to light gray and smooth, in age separating into thin plates.

nearly whorled, spreading-ascending;

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

spreading to ascending, often persistent to trunk base;

twigs stout, pale red-brown, with light brown, often glandular puberulence, somewhat roughened by elevated scars, aging gray to pale gray-brown.

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

ovoid, light red-brown, 0.8–1cm;

scale margins entire.

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.

5 per fascicle, mostly ascending and upcurved, persisting 5–8 years, 3–7cm × 1–1.5(–2)mm, mostly connivent, deep yellow-green, abaxial surface less so, adaxial surface conspicuously whitened by stomates, margins rounded, minutely serrulate distally, apex conic-acute;

sheath 0.8–1.2cm, shed early.

ellipsoid, 10–15mm, yellow.

cylindro-ovoid, ca. 10–15mm, scarlet.

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.

cones remaining on tree (unless dislodged by animals), not opening naturally but through animal agency, spreading, symmetric, broadly ovoid to depressed-ovoid or nearly globose, 4–8cm, dull gray- to black-purple, sessile to short-stalked;

scales thin-based and easily broken off;

apophyses much thickened, strongly cross-keeled, tip upcurved, brown;

umbo terminal, short, incurved, broadly triangular, tip acute.
