Flora of North America species comparison

red-brown to dark brown, shallowly and irregularly furrowed, ridges broad, scaly.

brown to gray- or red-brown, platy to furrowed.

spreading-ascending;

twigs red-brown, sometimes finely papillate, aging gray to gray-brown.

slender, orange to red-brown, aging darker brown, rough.

ovoid to short cylindric, pale red-brown, 0.5–1.2cm, slightly resinous.

narrowly to broadly ovoid, dark red-brown, to 1.2cm, slightly resinous.

(2–)3(–4) per fascicle, spreading to upcurved, persisting 3–4 years, 2–6cm × 0.6–0.9(–1)mm, connivent, 2–3-sided, blue- to gray-green, abaxial surface not conspicuously whitened with stomatal bands or if stomatal bands present, these less conspicuous than on adaxial surfaces, often with 2 subepidermal resin bands evident, adaxial surfaces conspicuously whitened with stomatal lines, margins entire to finely serrulate, apex narrowly conic or subulate;

sheath 0.5–0.7cm, scales soon recurved, forming rosette, shed early.

2 per fascicle, spreading or ascending, persisting 3–8 years, 2–8cm × 0.7–2(–3)mm, twisted, yellow-green to dark green, all surfaces with fine stomatal lines, margins finely serrulate, apex blunt to acute or narrowly acuminate;

sheath 0.3–0.6(–1)cm, persistent.

ellipsoid, to 10mm, yellow.

ellipsoid to cylindric, 5–15mm, orange-red.

cones maturing in 2 years, shedding seeds and falling soon thereafter, spreading, symmetric, ovoid before opening, broadly depressed-ovoid to nearly globose when open, 1–3.5cm, pale yellow- to pale red-brown, resinous, nearly sessile or short-stalked;

apophyses thickened, slightly domed, angulate, transversely keeled;

umbo subcentral, slightly raised to depressed, truncate or umbilicate.

cones maturing in 2 years or variably serotinous, variably persistent, spreading to reflexed, often curved, nearly symmetric or variably asymmetric, lanceoloid to ovoid before opening, broadly ovoid to nearly globose when open, 2–6cm, tan to pale red-brown, lustrous, nearly sessile or on stalks to 1cm;

apophyses nearly rhombic, variously elongate, cross-keeled, often mammillate toward outer cone base and on inside above middle;

umbo central, depressed-triangular, prickle barely elongate to stubby or slender and to 6mm.

branches often descending, the upper spreading or ascending.
