Description: This incredibly beautiful specimen is an example of the seed cone from Auraucaria mirabilis. This silicified cone has been sectioned and polished to show the wonderful interior (the species name says it all). It differs from pinecones in having only a single ovule (seed) in the cone scale, rather than a pair. The genus derives its name from the Arauco Province of Chile. Its closest relatives today are the Monkey Puzzle Tree of South America (I’ve included a photo of a branch section) and the Norfolk Island Pine.
