 Each region is designated by a name and a Roman numeral assigned from north to south, except for the Santiago Metropolitan Region, which does not have a number.The creation of two new regions in 2007, Arica and Parinacota (XV) and Los Ríos (XIV), and a third region in 2018, Ñuble (XVI) made this numbering lose its original order meaning.The national flower is the copihue ("Lapageria rosea", Chilean bellflower), which grows in the woods of southern Chile.
