The core Asterales are Stylidiaceae (6 genera), APA clade (Alseuosmiaceae, Phellinaceae and Argophyllaceae (7 genera)) and MGCA clade (Menyanthaceae, Goodeniaceae, Calyceraceae - total 20 genera), and Asteraceae (1600 genera). Other Asterales are Rousseaceae (4 genera), Campanulaceae (84 genera) and Pentaphragmataceae (1 genus).
All Asterales families are represented in the southern hemisphere; however Asteraceae and Campanulaceae are cosmopolitan and Menyanthaceae nearly so.
