An evergreen, coniferous tree (family Araucariaceae), native to southern South America (where there are no monkeys) and the national tree of Chile. It grows up to 50 m tall and has tough, thick, triangular leaves with sharp edges and points, and edible seeds. It is widely cultivated for ornament. It acquired its common name in 1850, when Charles Austin saw a specimen in Pencarrow Gardens, Cornwall, owned by Sir William Molesworth, and remarked that ‘it would puzzle a monkey to climb that’.
