Malus orientalis

Malus orientalis, the eastern crabapple or Caucasus apple, is a species in the genus Malus found in Bulgaria, Turkey (including East Thrace), the Transcaucasus, and Iran. With its relatively large yellow fruit, it has been consumed by people for millennia, with a string of halved, dried fruit being found in a royal tomb at Ur. Drying the fruit and then rehydrating by boiling cuts the tartness. M.orientalis contributed slightly to the gene pool of domesticated apples, a distant second to Malus sieversii.
