Leaves (4–)5–8cm × 1–2(–3)mm, yellow-green, apex narrowly acute to short-acuminate. Seed cones maturing in 2 years, then shedding seeds or variously serotinous, long-persistent, strongly asymmetric, mostly recurved, seldom whorled, mostly in 2s or solitary, mid and lower apophyses mostly much domed.

Discussion
Pinus contorta var. latifolia is fire successional. It is the most wide-ranging and commercially utilized variety. Its poor self-pruning character makes it less desirable for lumber but adequate for mine timbers, fences, and pulpwood.
Lodgepole pine (Pinus contorta var. latifolia) is the provincial tree of Alberta.
