An old, confused name, included only because it is still sometimes seen in books and other listings. Spach (1834) quite carefully described a tree of unknown origin grown in French gardens, suggesting that it resembled what might be expected of a hybrid between an orchard apple and an American species, strongly disagreeing with others’ opinion that it was a variety of M. sempervirens (a synonym of M. angustifolia), and commenting on its pale pink, highly fragrant flowers. Jacobson (1996) equates it with Rehder’s better-defined M. × platycarpa (q.v.). Fiala (1994) maintains the name for hybrids between M. coronaria and M. domestica, since he interprets M. × platycarpa as a variety of M. coronaria. However, Plants of the World Online (Royal Botanic Gardens, Kew 2020) lists it as a synonym of the Mediterranean Pyrus spinosa, although Spach’s description really does not suggest that species. The name is best left to sink into obscurity.
