The William Mohr Medal is the highest special medal awarded by the American Iris Society to Arilbred irises with less than 1/2 and more than 1/4 Aril content. The candidates are those Arilbred irises that have received the Award of Merit 2, 3, or 4 years ago. The winners of the medal are then among those eligible for the American Dykes Medal the following three years.
Here are the two candidate Arilbred irises on the 2015 ballot.
