Slash Pine - Pinus elliottii
Named for the flexible branches (which can be tied in simple knots), Limber Pine is a small tree of mountainous regimes, growing to nearly 12,000 feet in the Rocky Mountains. The long needles are borne in bundles of 5 and are glossy above with faint stomatal lines beneath. The bark is pale on young trees but dark brown and broken into scaly plates on older trees. The large cone (up to 8 inches) is pale and ovoid and opens at maturity. At timberline the trees are often dwarfed, but at lower elevations they may attain a height of 50 feet.
