Leaves directed forward (but not appressed) on upper side of branchlets, slightly directed forward on lower side, blue-green with slight bloom, (1.5-)1.8-2.3(-2.5) cm, flattened, parallel sided for most of length, covered with bright snow-white epicuticular wax adaxially, stomatal lines 5 or 6 in each of 2 bands adaxially, apex abruptly acute, somewhat pungent.

Pollen cones conical-cylindric, 2-2.5 cm × ca. 3 mm. Seed cones sessile or very shortly pedunculate (peduncle ca. 0.5 cm), mid brown, ellipsoid-cylindric, (6-)7-9.5(-10) × 3-4 cm when open.

Seed scales at middle of cones obovate, convex, 0.8-1.2 × 1-1.6 cm, distal margin ± incurved, rounded. Seeds ca. 1.6 × 0.5 cm including wing; wing pale brown, margin erose.[2]
