gray, nearly smooth, cross-checked in age into scaly plates and ridges.

red-brown, shallowly and irregularly furrowed, ridges scaly, rounded.

spreading to ascending, often persistent to trunk base;

twigs pale red-brown, puberulous (rarely glabrous), slightly resinous, aging gray, smooth.

persistent to near trunk base;

twigs pale red-brown to tan, rarely glaucous, aging gray-brown to gray, glabrous to papillose-puberulent.

ovoid, light red-brown, 0.9–1cm, resinous;

lower scales ciliolate along margins.

ovoid to ellipsoid, red-brown, 0.5–1cm, resinous.

5 per fascicle, spreading to upcurved and ascending, persisting 5–6 years, 3–7cm × 1–1.5mm, pliant, dark green, abaxial surface with less conspicuous stomatal bands than adaxial surfaces, adaxial surfaces with strong, pale stomatal bands, margins finely serrulate, apex conic-acute to acuminate;

sheath 1–1.5(–2)cm, shed early.

(1–)2(–3) per fascicle, upcurved, persisting 4–6 years, 2–4cm × (0.9–)1–1.5mm, connivent, 2-sided (1-leaved fascicles with leaves 2-grooved, 3-leaved fascicles with leaves 3-sided), blue-green, all surfaces marked with pale stomatal bands, particularly the adaxial, margins entire or finely serrulate, apex narrowly acute to subulate;
