Buds exposed, light brown, conic, small, resinous, apex acute; basal scales short, broad, equilaterally triangular, glabrous, resinous, margins entire, apex sharp-pointed. Leaves 1.2-2.5 cm x 1.5-2 mm, 2-ranked, particularly in lower parts of tree, to spiraled, flexible; cross section flat, grooved adaxially; odor turpentine-like, strong; abaxial surface with (8-) 10 (-12) stomatal rows on each side of midrib; adaxial surface dark lustrous green, sometimes slightly glaucous, with 0-3 stomatal rows at midleaf, these more numerous toward leaf apex; apex slightly notched to rounded; resin canals large, ± median, away from margins and midway between abaxial and adaxial epidermal layers. Pollen cones at pollination reddish yellow or yellowish green. Seed cones cylindric, 3.5-6 x 2.5-4 cm, dark purple overlaid with yellowish green bracts, sessile, apex round; scales ca. 0.7-1 x 1-1.3 cm, pubescent; bracts exserted and reflexed over cone scales. Seeds 4-5 x 2-3 mm, body brown; wing about as long as body, purple; cotyledons ca. 5" (Flora of North America online).
