“Polypodiaceae Bercht. & J.Presl, Přir. Rostlin: 272. 1820” was not validly published. On p. 272: “Rad Polypodiaceae” is published. Vienna Code Art. 18.2, Ex. 4: Names published at the rank of order (řad) by Berchtold & Presl (O přirozenosti rostlin .... 1820) are not to be treated as having been published at the rank of family, since the term family (čeleď) was sometimes used to denote a rank below the rank of order.
