Myrcianthes oreophila (Unka or Unca Tree) is a native species in high-altitude Andes of Peru. It is known for its hard, white wood, small, serrated leaves and white flowers. It rarely exceeds 16 feet in height. The tree canopy resembles an umbrella shape. It is often found along the Inca Trail. The Unka’s main ecological roles include watershed protection, filtration and soil erosion. They serve as a natural filtration system that traps water from mist and rain, which then feeds natural springs. Its strong root system anchors the soil. Historically, the wood was used by the Incas for their ceremonial vessels known as keros. The flowers are used to prepare a natural diuretic medicine. The Unka tree symbolizes endurance and strength.
