Tree to 10(-20) m tall, with trunk to 0.6(-1.2) m in diameter. Bark ridged and furrowed or smooth and peeling in flakes, grayish brown. Crown dense, conical, broadening with age.

Scale leaves on branchlets 1-2 mm long, dark green or gray-green with wax, the edges minutely toothed, the back usually with a conspicuous drop of dried resin in an open gland. Pollen cones 2-5 mm long, about 2 mm wide, with (4-)5-8(-10) pairs of pollen scales, each with (three or) four to six pollen sacs. Seed cones spherical or a little elongated, (1.5-)2-3(-3.5) cm long, gray or brown at maturity, often waxy before this, with three or four (to six) pairs of seed scales, each usually with a strong conical point on the face, especially on the upper scales, the surface otherwise smooth or warty.

Conservation Status

Red List Category & Criteria: Endangered

(This variety meets criteria B1abc and 2abc for listing as Endangered, as destructive fires can wipe out entire subpopulations (“groves”) and thereby drastically reduce the number of mature individuals in the population (resulting in continuing declines and extreme fluctuations). If this should happen in the largest subpopulation, more than half of all mature trees might be destroyed. Regeneration usually follows fires, but the success of this will decline as fire frequency changes thus making the population subject to extreme fluctuations. Changes in fire frequencies (either too frequent or too infrequent) can work negatively on the successful regeneration to mature trees)
