Flora of North America species comparison

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

orange- to red-brown, scaly.

contorted, pendent;

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

descending to spreading-ascending, poorly self-pruning;

twigs slender, orange-red to red-brown, aging gray-brown, rough.

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

ovoid, red-brown, 0.5–1cm, resinous;

scale margins nearly entire.

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.

2 per fascicle, spreading or ascending, persisting 2–3 years, 2–5cm × 1–1.5(–2)mm, twisted, yellow-green, all surfaces with fine stomatal lines, margins finely serrulate, apex acute to short-subulate;

sheath 0.3–0.6cm, semipersistent.

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

cylindric, 10–15mm, yellow to orange-brown.

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 soon thereafter or often long-serotinous and shedding seeds only through age or fire, upcurved, asymmetric, lanceoloid before opening, ovoid when open, 3–5.5cm, tan to light brown or greenish yellow, slick, nearly sessile or short-stalked, most apophyses depressed but increasingly mammillate toward outer cone base;

umbo central, depressed, small, sunken centrally, unarmed or with a small, reflexed apiculus.
