 | | The first comprises Caryophyllaceae (86 genera, 2,200 species; mostly with a temperate distribution), Achatocarpaceae (3 genera, 7 species; western North America to South America), and Amaranthaceae (including Chenopodiaceae; 174 genera, 2,050 species; warm temperate and subtropical regions) form a clade, with the last two as sisters. |

 | | A third clade within core Caryophyllales is composed of Aizoaceae (125 genera, 2,020 species; mostly warm southern Africa and Australia) and Nyctaginaceae (30 genera, 395 species; pantropical)—each of which is monophyletic—and Phytolaccaceae (18 genera, 65 species; pantropical to warm temperate) and its segregates. |
