Kortbawi Lebanese unknown is a family heirloom from a good friend of mine. His family brought it to America approximately 140 years ago. Their family has been growing it ever since!  It does appear to perhaps fit into the mt Etna family. However, it has been showing pinkish colors on some stems & leaf undersides. After being with the owner he confirmed his does indeed have these pink colors.
 
This tree is currently growing in a tallboy treepot.
