The Rosales includes 9 families and about 6300 species; the monophyly of this order is supported by molecular phylogenetic analyzes and characterized morphologically by a reduction or lack of endosperm and the presence (Rosaceae, Rhamnaceae, and some Ulmaceae) or absence (Cannabaceae, Urticaceae, and Moraceae) of a hypanthium. However, phylogenetic relationships within order are still not well resolved, but the principal families recognized are Rosaceae, Rhamnaceae, Ulmaceae, Cannabaceae, Urticaceae, and Moraceae. This Family is cosmopolitan and most abundant in the Northern hemisphere with showy species such as apples, pears, peaches, plums, cherries, almonds, apricots, firethorns, meadowsweets, hawthorns, etc. The genus Rosa L. (Roses) are perennial, dicotyledonous plants belonging to the sub-family Rosoideae.
