siberian crabapples collected from various trees at a few sites

siberian crabapples collected from various trees at a few sites. these tiny ones on the right are a new phenotype to me, I initially thought they were prunus. wild or ornamental malus baccata is the best description of them, interesting that the fruit more closely resembles other rosacea, the overripe fruits are sticky not mealy, the seeds have no discernible husk, there’s 8-10 or more seeds, and they’re the size of pin cherries. is it possible there’s some hybridization with another malus, or does this apple have some other name?
