 found not to be the same plant, but to be distinct from that species and varietally related to Sorbus americana 

 Marshall. Usually shrubby in the Northwest but sometimes 1.5 to 20 feet high and 2 to 3 inches in diameter 

 (Toneass National Forest ), Planted for ornament in Alaskan towns, it attains a height of 30 or 40 feet 

 (fide C. T Gardner, Forest Supervisor, Tongass National Forest).
