Leaves 1-3 (-3.5)cm x 1.5-2mm, 1-ranked, flexible, proximal portion often appressed to twig for 2-3mm (best seen on abaxial surface of twig), distal portion divergent; cross section flat, with prominent raised midrib abaxially, with or without groove adaxially, or cross section 4-sided on fertile branches; odor pungent, faintly turpentinelike; abaxial surface with 2-4 glaucous bands, each band with (4-) 6-7 stomatal rows; adaxial surface bluish green, with 0-2 glaucous bands, each band with 0-7 stomatal rows at midleaf; apex rounded to notched; leaves on fertile branches 4-sided with 4 bands of stomates below; resin canals small, near margins and abaxial epidermal layer. Pollen cones at pollination ± purple, ± red, or reddish brown. Seed cones oblong-cylindric, 10-15 x 5-6.5cm, green, red, or purple, overlaid with green bracts, at maturity brown (bracts light-colored and scales dark), sessile, apex rounded; scales ca. 2.5 x 3cm, pubescent; bracts exserted and reflexed over scales.
