Rosales (Rose)


The order Rosales contains about 8000 species, including many of economic and ecological importance. The nine families of this order are divided into three major subgroups: the rose family (Rosaceae), the urticoids (figs, nettles and relatives), and the rhamnoids (buckthorns and relatives).

Keywords: phylogeny; apple; pear; DNA sequence; evolution
