A confused and unhelpful name; we quote and fully endorse Bean (1981): ‘This name is really of no service in horticultural nomenclature but appears in several manuals and must be mentioned. The parentage was originally given by Zabel as M. dasyphylla × M. baccata, without description. Rehder gave the first parent as M. pumila [i.e. Malus domestica] and referred to this group various hybrid crabs raised in the USA from the crossing of orchard apples with “Siberian” crab.’
Since it seems highly likely that some hybrid crabs of unknown parentage would belong here, and because M. baccata is anyway involved in some modern M. domestica breeding programmes, it seems pointless to single out particular cultivars as belonging here. Those that have been include ‘Hopa’, ‘Hyslop’, ‘Martha’ and ‘Transcendent’ (Fiala 1994).
