Abies lasiocarpa

Subalpine fir is a North American fir in the pine or Pinaceae family native to western North America from the Yukon to much of British Columbia and parts of Alberta in Canada, and extending down into interior western states in the U.S., being distinct to high elevation sites. Trees can reach 50 m tall.

• Tree crown is narrow, spire-like.
• Needles are flat, 1.5–3.0 cm long, glaucous green above with a broad stripe of stomata, and two blue-white stomatal bands below; the fresh leaf scars are reddish. They are arranged spirally on the shoot, twisted to be above the shoots. Needles are attached to the twig by a base resembling a small suction cup.
• The species is monoecious. Cones are erect, 6–12 cm long, dark blackish-purple with fine yellow-brown pubescence, ripening brown and disintegrating to release the winged seeds in early fall.
• Buds are globose, small, resinous, tan to dark brown; bark on young trees is smooth, gray, and with resin blisters, becoming rough and fissured or scaly on old trees.
