INTRODUCTION TO ARAUCARIAS

ARAUCARIA species

Araucariaceae

Members of the araucaria family (Araucariaceae) are cone-bearing trees of ancient lineage. They have cone scales with only one seed per scale. Some can grow quite large, and are, or have been, important timber sources. 

Araucaria is the largest genus in the araucaria family, comprising 19 or 20 species, and all are native to the southern hemisphere. Almost all species are found in tropical or subtropical rainforest, except the monkey-puzzle tree, which inhabits montane areas in South America. Other genera are Agathis and little known Wollemia.

Araucarias are evergreen trees with regularly whorled branches. Leaves are scale-like or needle-like. Male and female cones occur on the same tree; the female cones are quite large, and ripen in 2–3 years. The seeds of Bunya-bunya (Araucaria bidwellii) are large and nourishing, still considered by many to be a delicacy.

CHILEAN PINE or MONKEY-PUZZLE TREE (Araucaria auracana) is native to the southern mountains of Chile and southwest Argentina. Monkey puzzle tree may live 1000 years. It is unusual within the genus in occupying dry habitats, which is typical for many conifers that attain great age. This specimen is one of a few at the University of California Botanical Garden in Berkeley, California. Alas, most there do not seem to be thriving. Monkey puzzle is fire adapted, though risks extinction in the wild due to limited and severely fragmented distribution, coupled with ongoing habitat reduction.

NORFOLK ISLAND PINE (Araucaria heterophylla, formerly A. excelsa), native to Norfolk Island east of Australia.

Widely planted in San Francisco Bay Area, more.
