2n= 74 (2x). - Asia (China), Far East (Japan), Canada (Saskatchewan and Manitoba). - Kurita (1963); Haufler and Wang (1991).

Geography: Asian (C-NE) - amphi-Pacific - North American: ALA CAN GRL.

Notes: Haufler et al. (1993b) considered the northeastern Asian and North American Polypodium sibiricum one of the diploid parents of the tetraploid eastern North American P. virginianum L. (non-arctic). They referred the name "columbianum" to the tetraploid, southwestern North American P. hesperium Maxon (non-arctic), of another parentage altogether.
