In this redistribution the four species of '' Famatina'' were polyphyletic and ''F. maulensis'' segregated with ''Phycella'' and was consequently transferred: The generic distribution here is based on Garcia et al 2019. * 'Placea'' previous genus* '' Phycella'' (~13 species) * '' Rhodolirium'' (2 species) * ''
