General: Limber Pines (Pinus flexilis) are coniferous (cone-bearing) trees with medium-length, roundish, light green needles that form tufts at the end of the branches. Needles set in bundles of 5, and the bundles radiate in all directions from the twigs. The bark is light colored (white to gray). The cones are cylindrical, to 8-inches long, and the cone scales have thick tips.

In Nevada, Limber Pine is an uncommon component of the montane vegetation in the Spring and Sheep mountains in the Transition (Yellow Pine Forests), Canadian (Pine-Fir Forest), and Hudsonian (Bristlecone Forest) life zones. This species is more common north of the Las Vegas region.
