Phyllocladus alpinus is a type of coniferous tree that grows in mountainous regions. Some synonyms for this species include alpine totara, mountain pine, and celery top pine. These names are reflective of the tree's characteristic thin, needle-like leaves (or "phylloclades") that resemble celery stalks. Phyllocladus alpinus is also known as a slow-growing tree, with an estimated lifespan of up to 800 years. This longevity has been attributed to the tree's ability to tolerate extreme weather conditions, such as freezing temperatures and high winds. Due to its unique physical characteristics and resilience, Phyllocladus alpinus holds an important ecological and cultural significance in various parts of the world.
