Pinus monophylla (One-Leaf Pinyon Pine)

Pinus monophylla, commonly known as the One-Leaf Pinyon Pine, is a slow-growing evergreen tree native to the southwestern United States and northern Mexico. It is characterized by its unique feature of having only one needle per fascicle, hence the name 'monophylla.' The tree has a dense, rounded crown and thick, fissured bark. It produces edible pine nuts and its wood is highly valued for its durability and straight grain.
