Leaves 0.6–1.5(–2)cm, 4-angled in cross section, rigid, pale blue-green, glaucous, bearing stomates on all surfaces, apex mostly blunt-tipped. Seed cones 1.5–2.5(–3.5)cm; scales fan-shaped, broadest near apex, 8–12 × 8–12mm, rigid, margin at apex irregularly toothed. 2n =24.

Discussion
To a limited extent, Picea mariana hybridizes with P. rubens, e.g., on disturbed sites in eastern Canada. Natural hybridization with P. glauca, though reported, remains unverified (A.G. Gordon 1976).
Because Picea mariana is a small tree, it has limited commercial value. Frequently it is harvested with P. glauca and used for pulp.
Black spruce (Picea mariana) is the provincial tree of Newfoundland.
