. Further investigations have also shown that the South American genera '' Arjona'' and '' Quinchamalium'' (previously in the family

) are part of this family. Thus the family contains three genera. ''Quinchamalium'' was thought to comprise 21 species in 2015, but this was reduced to a single widespread and morphologically variable species in that year. Christenhusz ''et al''. claimed there was a total of 58 known species in 2016, but for some reason counted 25 species of ''Quinchamalium'' and eight of ''Arjona''. *'' Arjona'' Cavanilles (5 or 6 species) – western and southern South America *'' Quinchamalium'' Molina (1 species) – Andes and temperate South America *'' Schoepfia'' Schreber (25 species) – temperate and tropical East Asia, tropical America
