All except Vauquelinia (with 15 chromosomes) have a basal haploid

Malus florentina, the Florentine crabapple, Italian crabapple, or hawthorn-leaf crabapple, is a species of apple (Malus) in the rose family (Rosaceae). It was first described in 1806 as Crataegus florentina, however, the species' taxonomy was unclear for decades, and it was at times considered to be a natural hybrid between the wild service tree (Torminalis glaberrima) and the European wild apple (M. sylvestris). Today, its inclusion in Malus is largely undisputed. It is a small deciduous tree with dark-green leaves, characterised by large, white flowers, small fruit, and a late flowering
