Dickinson et al. (2002) has produced a parsimonious tree derived from the
cladistic analysis of 125 combined morphological and molecular characters from
members of the Rosaceae (Fig. 2) and added several genera to Maloideae. Spiraeoideae,
no longer monophyletic, is split by Amygdaloideae (Prunoideae). The
Rosoideae have been subdivided into individual tribes. Thus, Dickinson et al.
recircumscribes Maloideae and Rosoideae, the two largest subfamilies.
