bristlecone pine. Called the “oldest living things on earth,” some gnarled, twisted bristlecone pines (Pinus aristata) in Cali- fornia’s White Mountains are more than 5,000 years old. Named for the bristle-like prickles at the end of its cones, this slow- growing tree also goes by the names Jack pine, cattail pine, and foxtail pine, the last two names alluding to the tufts at the ends of its twigs. |
