Ponderosa pine (Pinus ponderosa willamettensis) is a type of pine that prefers more inland sites. Also known as the yellow pine, it is characterized by its long needles, grouped into threes ten to twenty centimeters long. Its scaly bark is cinnamon-brown and to some smells like vanilla. Its cones are prominent, usually in groups of threes, shaped like an egg. The scales are thick with triangular, pointed tips arranged in a spiral pattern down the center. It is associated with Douglas-fir in many inner forests of the Pacific coast, as far east as Oklahoma and as south as Texas.
