This species does not seem to be closely related to anj- other Sorbus. In the 

 inferior ovary and in the 3-4 styles connate below the middle, it agrees with S. 

 Hedlundii Schneider, but differs from it in the much larger russet-colored fruit 

 and the glabrous leaves which resemble certain species of the section Micromelcs, 

 as S. aronioides Rehder and S. meliosmifolia Rehder.
