About 65 species of the Himalayas and adjacent south China. Considered as a subgenus of Arenaria by many (e.g., McNeill 1962), Harbaugh & al. (2010) proposed, and Sadeghian & al. (2015) confirmed, that Odontostemma should be treated as a genus, clustering with Stellaria and Cerastium rather than Arenaria. Work on new combinations necessary for recognizing most species in Odontostemma is underway (R. K. Rabeler & W. L. Wagner, unpubl. data).
