Balsam Fir (Abies lasiocarpa)

Balsam Fir (Abies lasiocarpa)

This small conifer has smooth bark divided by shallow fissures somewhat roughened by cinnamon-red scales, and drooping lower branches, the upper ones forming spire-like heads. If you take hold of a branch it feels quite soft in the hand. The needles which are rounded or shallow-notched at the apex, are whitish below with a green midrib and the two resin-ducts are imbedded in them. The buds are small, round and gummy.
