We revisit the Triangle of Citrus to discuss a cornerstone of the shape, the Mandarin orange (Citrus reticulata). We talk etymology, genetic diversity and interbreeding before a visit from a pair of happy carolers. Merry Christmas!

Completely Arbortrary is produced and hosted by Casey Clapp and Alex Crowson
