Notes

About 160 species, in north temperate areas, the Mediterranean, and Andean South America. Harbaugh & al. (2010), Greenberg & Donoghue (2011), and most recently Sadeghian & al. (2015) have sampled Arenaria and, between their results, have removed about one-half of the species into four segregate genera not aligning in the same tribe as Arenaria. Sadeghian & al. (2015) found that four of the five remaining subgenera that McNeill (1962) recognized form Arenaria s.str., with the placement of subg. Dicranilla still unknown. While a few of the infrageneric groups recognized by McNeill (1962) are confirmed by molecular results (e.g., sect. Plinthine, subg. Leiosperma), most are not.
