Basionym Pinus pendula Aiton.
Much confusion over the taxonomy. Tropicos considers this the accepted name but Kew says it is a synonym of Larix x pendula (Aiton) Salisb.
Based on the explanation of circumstances from Hillier (see Larix x pendula) and the fact that there is no plant information available for Abies pendula in today's sources, I concur with Kew.
